  1. Miracle-Gro Water Soluble Azalea, Camellia, Rhododendron Plant Food

This water-soluble fertilizer from the well-known brand Miracle-Gro is specially formulated to provide adequate nutrition to acid-loving plants. Available in packs of 1.5 lb, 4 lb, and 5 lb, this product feeds and acidifies the plant at the same time.

Miracle-Gro Water Soluble Azalea, Camellia, Rhododendron Plant Food, 5...
  • Instantly feeds acid-loving plants for lush...
  • Feed every 1-2 weeks

Why Did We Like It?

What we loved about this product was that it feeds the plant instantly to provide beautiful blooms and lush green foliage in a much shorter time.

For getting best results, you need to use the fertilizer once every one or two weeks. Applying the product is very simple, as you just need a Miracle-Gro Garden Feeder or any watering can. Also, be assured that the fertilizer won’t harm other plants in the garden or burn foliage if used as advised.

Besides, this product can be used for both outdoor and indoor plants. You just need to ensure that the right amount of fertilizer is being used. For outdoor plants, you need to mix 1 tablespoon of Miracle-Gro per gallon of water, but ½ teaspoon is sufficient for indoor plants.

Furthermore, a 1.5 lb pack of the product can feed plants spread over an area of about 600 square feet.

What Could’ve Been Better?

Although the product is really great for hydrangea plants and gives you the results you desire to see, we felt its packaging needs to improve. We received a big plastic bag containing the fertilizer instead of a canister as shown in the pictures on online shopping sites. It was difficult to store and had the measuring spoon lying loose in the box.

Pros
  • Easy to use
  • Suitable for both indoor and outdoor plants
  • 1.5 lb pack covers 600 sq ft.
  • Promotes beautiful and quicker results
Cons
  • Packaging not consistent
  1. Osmocote Smart-Release Plant Food Plus

Our next pick for you is this all-in-one solution for potted plants from Osmocote. This fertilizer can be used for all plant varieties and also works equally well in all growing conditions. It comes in a pack of 8 lbs and can feed a plant for up to 6 months.

Sale
Osmocote Smart-Release Plant Food Plus Outdoor & Indoor, 8 lbs
  • Our best formula, fortified with 11 essential...
  • Works with virtually all plant varieties, in all...

Why Did We Like It?

We loved how the product could be applied by just sprinkling it onto the soil and then mixing it properly; all that is needed afterward is regular watering. And the fertilizer consists of the 11 most essential nutrients that the plant needs. It is derived from ammonium nitrate and is a slow-release fertilizer designed to feed your plant gradually.

Interestingly, this product has a unique way of supplying essential nutrients to plants. Each of its granules is coated with a semi-permeable resin. As a result, when water is applied to the plant, the coating allows it to penetrate within and dissolve the nutrients.

These dissolved nutrients are then released during temperature changes. So, warmer periods are more favorable for the rapid release of nutrients. What remains after the release is the empty shell of the granules.

What Could’ve Been Better?

We loved this product as it resulted in abundant blooms in our hydrangea plants. However, sometimes we found that the granules took longer to dissolve. So, in turn, the results were visible after a longer period. This might be due to a possible change in the formula.

Pros
  • Unique resin-coated granules
  • Easy to apply
  • Slow-release fertilizer
  • Works well in all growing conditions
Cons
  • Might take longer to dissolve sometimes
  1. Jobe’s Organics Soil Acidifier

This product from Jobe’s Organics is another great source of nutrition for acid-loving plants like hydrangea. It is verified by OMRI as a standard organic gardening product and comes in an easy to pour 6 pound bag.

Jobe’s Organics 9364 Fertilizer, 6 lb
  • Organic granular for decreasing soils alkalinity;...
  • OMRI listed for organic gardening by usda;...

Why Did We Like It?

Soils which possess greater alkalinity are not ideal for the acid-loving hydrangea plants to thrive. As such, a fertilizer is needed which can help the soil acquire the right pH. And this one from Jobe’s Organics is one of the best options you will come across.

Its special formula provides acid-loving plants with sulfur, which is a natural ingredient used for correcting alkaline soils. This gives a boost to your hydrangea plant’s health, and helps it to produce prettier and more vibrant blue flowers. Note that you should conduct a soil test before applying this soil acidifier.

Besides, this product uses fully natural ingredients, and hence, poses no threats of contamination by harmful chemicals. It is also safe for use around pets and children. Furthermore, this soil acidifier is also a cost-effective option to go for.

What Could’ve Been Better?

This product gave wonderful results for most of our hydrangea plants. However, the instructions for applying the product to potted plants seemed to be a bit unclear. We used the amount recommended but found that some of the leaves were burnt after the application. Although the burnt parts did recover within a couple of days.

Pros
  • Completely natural ingredients
  • Pet and child safe
  • Cost-effective option
  • Produces prettier blooms
Cons
  • Instructions for potted plants unclean
  1. Flower Fuel 1-34-32

The next pick we have for you is this super-effective bloom booster from Element. It contains a variety of nutrients along with more resin and oil which together help in achieving heavier, larger and denser harvests. This fertilizer comes in packs of 200 gm, 1000 gm, 5000gm and 20000 gm to suit your growing needs.

  • Flower Fuel is a super-premium bloom booster....
  • Formulated to achieve larger, denser and heavier...

Why Did We Like It?

Achieving large and beautiful blooms in abundance is something which every gardener dreams of. But due to inadequate nutrient availability, the results often tend to be quite different from the expectations. So, what you need to make sure is that the plants are getting the right nutrients at the right time.

This can be ensured with the superior-quality Flower-Fuel fertilizer, which encourages plants to absorb all vital organic compounds and nutrients at an accelerated rate. Behind this “magic” is a proprietary and complex mix of high-end hormones and vitamins and chelating agents. Besides, this efficient mix also includes bio-available forms of potassium and phosphorus.

Furthermore, this fertilizer works wonderfully with any base nutrient including the popular 3-part and 2-part nutrients. It can be used in any kind of soil and hydroponic or aeroponic horticulture systems.

And that’s not all. Each pack includes a 2.5 teaspoon and ¼ teaspoon scoop for adding correct amounts of fertilizer according to your needs.

What Could’ve Been Better?

Although the fertilizer is quite effective on hydrangea plants and produces just the results you would want to see, its packaging might be faulty sometimes. We had received a jar with a broken lid which has to be glued back together. So, be sure to check the packaging when the product arrives.

Pros
  • Suitable for all soil types
  • Includes convenient measuring scoop
  • Promotes accelerated nutrient absorption
  • Includes bioavailable forms of potassium and phosphorous
Cons
  • Packaging may be faulty

Applying this product is also quite easy. You just have to add two teaspoons of the product to 1 gallon of water in your garden-feeder or watering jug. Note that the solution must be applied at the base of the plant. For getting best results, feed the blooming plants every 7-14 days.

On the whole, this fertilizer provides your hydrangeas with the exact growing environment that they need. It helps to make the soil pH suitable for these acid-loving flowers. Furthermore, applying this product won’t lead to any burns if the feeding instructions are followed.

What Could’ve Been Better?

This product works quite well on hydrangeas and gives us perfect blooms. However, once we found the fertilizer color to be much lighter than the usual intense bluish-green. This might be due to a change in formulation but there was no mention of this on the label.

Pros
  • Provides suitable growing environment
  • Helps achieve perfect blooms
  • Easy to apply
  • Feeding plants every 1-2 weeks is sufficient
Cons
  • Fertilizer color might vary with different purchases

  • Can be used both as a plant food and as a soil...

Why Did We Like It?

This soil acidifier is formulated to lower the soil pH to the level that is best for any acid-loving plant. As a result, you can achieve optimal growth for your hydrangea plants. And you will get the blooms in the blue and beautiful form that you want.

Added to this, it contains all the vital nutrients that the plants require. These nutrients also include high amounts of pure minerals which provide nourishment to all parts of the plant. As such, you don’t need to buy a separate plant food product for your hydrangeas.

Besides, this product is much more long-lasting than several others. It ensures a sustained availability of nutrients for the plant for as long as two months. So, no hassles of frequent application are involved. This also makes sure that the fertilizer doesn’t leach into the ground and surface water.

What Could’ve Been Better?

Although the product gave us the blue blooms that we desired, for some plants it took much longer to act. While we got beautiful blooms in a few within around 2 months, others took as much as six months to show the results. So, if you have a lot of acid-loving plants in your garden, it might require a little more patience to see all of them producing abundant blooms.

Pros
  • Lowers soil pH to the suitable level
  • Contains highly pure minerals
  • Helps in achieving optimum growth
  • Long-lasting nutrient source
Cons
  • Might take longer to act on some plants
  1. Burpee Organic Bone Meal Fertilizer

This bone meal fertilizer from Burpee is a great choice for ensuring ideal growth and development of your hydrangea plants. It is highly suitable both for giving a boost to established flower gardens and for nurturing new bedding plants.

Burpee Organic Bone Meal Fertilizer, 3 lb (1 Pack)
  • Why bone meal? - provides vital Organic nitrogen,...
  • Strong roots, vibrant blooms - promotes strong...

Why Did We Like It?

Phosphorus and calcium are two key nutrients required for the ideal development of all parts of your hydrangea plant. But often most of the products have insufficient quantities of these essential elements. However, with this fertilizer from Burpee at home, you don’t need to worry about this problem.

This fertilizer contains high amounts of bone meal which is a natural source of calcium and phosphorus. An early-season addition of phosphorus to the soil will help in promoting root strength and nourishment, which in turn will enhance early season growth.

As a result, you achieve superior-grade blossoms during harvest time. Interestingly, its bone meal content enables sustained release of nitrogen which helps to maintain robust growth all through the season. Besides, applying this fertilizer to young plants gives them a nutritional boost and keeps them strong during the growing season.

What Could’ve Been Better?

Though this product works wonderfully on hydrangea plants, it may be overpriced if you purchase it from online shopping sites. In comparison, the price offered in any local store close is much more reasonable. It is nearly three times less than the price shown online.

Pros
  • Results in vibrant superior-grade blooms
  • Enhances early season growth
  • Rich in nitrogen
  • OMRI listed for organic gardening
Cons
  • Much costlier if purchased online
  1. Bonide (BND56428) – Bailey’s Color Me Blue Hydrangeas Pellets

  • TURNS HYDRANGEAS BLUE - One of the most beautiful...
  • LOWERS SOIL PH - For amazing blue blooms on your...

Why Did We Like It?

The pH level needed to achieve amazing blue blossoms of hydrangea is between 5.0 and 5.8. And this product from Bonide acts quite efficiently to lower your pH into this range. Using a soil tester for an accurate pH reading is recommended before applying this fertilizer as well.

For bringing your soil pH to just the desired level, this fertilizer uses 90 percent elemental sulfur. This sulfur is oxidized by soil bacteria to form sulfuric acid which brings about the change. Notably, the product is also highly suitable for already blue flowers as it promotes vivid color and more vigor.

Furthermore, the acidifier is very easy to apply as it doesn’t need any mixing. Measurement is also made simple by a measuring scoop which is included with the jar. So, you can scoop the pellets directly into the soil. Just ensure that you water the plants well after application.

What Could’ve Been Better?

Though this product is extremely useful for amending the soil quality, it is not recommended for use as a fertilizing substitute. As such, you will have to get a separate fertilizer for the plant to ensure adequate nutrient availability. This just means that you will have to spend a bit more for your plants.

Pros
  • Maintains accurate pH level
  • Gives more vigor and vivid color
  • Purely organic
  • No mixing needed
Cons
  • Not recommended for use as a fertilizer
  1. J R Peters Inc 59324 Jacks Classic Hydrangea Fertilizer

JR Peters is a leading brand in the horticulture industry and is well-known for bringing innovation to the production of water-soluble fertilizers. This product from the brand consists of several beneficial nutrients and comes in a pack of 1.5 pounds. It has an N-P-K ratio of 7-3-3.

Why Did We Like It?

This fertilizer contains a perfect combination of high-quality nutrients and ammonium sulfate to promote a holistic development of the plant.

While the micronutrients provide a nutritional boost to the plants, ammonium sulphate helps to create the ideal environment for growth. The latter lowers the soil pH to make it suitable for acid-loving plants.

On using the product as recommended, your hydrangea plants are sure to produce lush green leaves and more vibrant blue blossoms. Generally, you can spot healthier and fuller leaves within just a few weeks.

Also, this product is easy to apply as you just have to soak the roots with the fertilizer solution. During the first month it should be applied at the rate of 1 tablespoon per gallon of water every 14 days. In the subsequent months, feeding once a month would be sufficient. Note that the right time to apply this fertilizer is during early morning late evening.

What Could’ve Been Better?

This product is highly beneficial in providing the required nutrition to the plants and makes them look healthier within weeks. However, it may not always turn the color of the blossoms into an intense blue. The flowers might turn lavender in some cases. So, if you want a more intense color in your blossoms, this might not always show the result you desire.

Pros
  • Lowers pH of soil
  • Promotes lush green leaves
  • Easy to apply
  • Results in a holistic development of the plant
Cons
  • May not always promote intense blue blossoms
  1. Espoma HT18 Holly Tone

Espoma HT18 Holly Tone, 18-Pound
  • Plant Food For Acid-Loving Plants And Is...
  • It Is Used By Professionals Everywhere

Why Did We Like It?

This product contains beneficial biotone microbes which help in enriching the soil with a variety of essential nutrients. This way, you get beautiful blooms and healthy plants through regular application. And you won’t get these special microbes in any other fertilizer, as these are proprietary to the brand.

Besides, this product even contains substantial amounts of magnesium, calcium and sulfur. These minerals help in providing the soil quality needed for acid-loving plants to thrive. Added to this, the fertilizer is free from any extra chemicals, and is thus, completely safe for the soil and plants.

Moreover, you can get this fertilizer in other bigger packs starting from 36 lb to 50 lb. If you have many hydrangea plants in the garden, buying such bigger bags will be a good idea.

What Could’ve Been Better?

Though we were more than satisfied with how the product turned out to be, we had an issue with the packaging. When the product arrived, we found that the bag was torn and taped up with duct tape. As such, it also became a bit difficult to read the instructions printed on the backside. So, make sure you check the packaging at the time of arrival if you are buying the product online.

Pros
  • Improves soil quality
  • Contains calcium, magnesium, and sulfur
  • Comes in bigger sizes suitable for more plants
  • No extra chemicals added
Cons
  • Packaging may be faulty
  1. Bonide Product INC 037321007050 Aluminum Sulfate

Another excellent choice for a soil acidifier would be this one from Bonide Products.

This product comes in a 4 lb bag and is suitable for all acid-loving plants.

  • LOWERS SOIL PH - 5.0 is a suitable pH for many...
  • ACID LOVING PLANTS - Aluminum Sulfate is designed...

Why Did We Like It?

Maintaining a perfect pH level of the soil is a must for achieving bright and beautiful hydrangea blooms. However, an ordinary acidifier may not always yield the desired pH level of the soil.

A pH of 5.0 is considered ideal for a plant that thrives in an acidic environment. And with this Ammonium Sulfate pack from Bonide, you can easily lower your soil pH to this target. Besides, it helps in achieving blue blossoms as well.

You can use this product for all types of soil including clay, sandy and loamy soil. Thus, unlike many other acidifiers, you don’t need to worry about whether it will work in your soil type.

Applying this product is also easy, as you just have to blend in in the soil and water thoroughly afterward. At least two weeks after the application, you should recheck the soil pH and reapply until the desired level is reached.

Furthermore, the acidifier comes with an application chart which mentions the amount of Ammonium Sulphate needed to lower the pH to 5.0.

What Could’ve Been Better?

Although we were able to achieve the exact pH level quite comfortably with this product, we had an issue with its storage. It so happened that we prepared premixed soil batches for various plants and stored them in totes. But this product absorbed the moisture from the surroundings, and turned into a crystalline coating over the growing medium.

Pros
  • Can yield blue colored hydrangeas
  • Lowers pH of soil to 5.0
  • Comes with application chart
  • Comes in 4 lb. bag
Cons
  • Can absorb moisture to turn crystalline

  • FOR ALL ACID LOVING PLANTS - E Z-gro 21-7-7...
  • DESIGNED FOR - Hydrangeas, rhododendrons, azaleas,...

Why Did We Like It?

What we loved about the product is that it efficiently delivers optimal nutrition to the plants to produce large and beautiful blossoms. This is possible due to the enhanced micronutrient package blended in this fertilizer. It also helps in reducing the soil pH considerably, thereby making iron and other trace minerals available to your hydrangea plants.

Besides, its concentrate liquid form makes it easy to use, as it just needs to be mixed with water and applied to the soil. To help in applying an accurate amount of the fertilizer, there is a free measuring cup included with the product.

Ideally you should apply the fertilizer during morning or late in the afternoon. Aso, make sure that you don’t pour it directly on the foliage, as that might damage the plant. On planting, you should apply it at a rate of 2.5 oz every two weeks for the first month. Then onwards, you can feed the same once a month.

What Could’ve Been Better?

This product makes the plants much healthier and the blossoms more beautiful and vibrant. However, it may not be ideal if you want to turn your blossoms into blue. In fact, it gives such results only in rare cases. Hence, you should choose another product if you aim to achieve blue blossoms.

Pros
  • Delivers optimal nutrition to plants
  • Comes with measuring cup
  • Can be used just by mixing it with water
  • Reduces soil pH considerably
Cons
  • May not turn blossoms into blue

Hydrangeas Fertilizer Buyer’s Guide

Achieving beautiful hydrangea plants with abundant blooms is not a herculean task at all. You just need to provide adequate care to the plant and make sure it receives all the necessary nutrients regularly.

So, purchasing the right fertilizer is of utmost importance and shouldn’t be taken lightly. Here are some important points that you need to keep in mind before you go on to choose a suitable fertilizer for your hydrangea plants.

  1. The Soil Type

You need to figure out the type of soil in your garden. Generally, hydrangeas grow well on light soil since it makes for convenient drainage. So, if the soil is heavy or clay-like, you should consider adding organic fertilizers to improve it.

Checking the soil acidity is also a very important factor before you move on to choose a hydrangea fertilizer. Plus, while going through the product details of a particular fertilizer, make sure to check whether it is suitable for your soil type.

  1. Type of Hydrangea

This is another essential factor to keep in mind. Every hydrangea plant has its own unique timing and nutrient needs. For instance, smooth hydrangeas require a fertilizer only during winter. However, plants with big leaves need frequent application throughout the first six months of the year. And as for the panicle and oakleaf hydrangeas, they are better with two hydrangea applications in April and June.

  1. Cost

You must keep in mind your budget before you go on to choose a fertilizer. That’s because products made by different manufacturers come in different prices and sizes. Although the cost is never the sole factor to determine the effectiveness of a fertilizer, it can be a challenge if you have a tight budget.

  1. Ease Of Use

Different methods of application are suitable for different types of fertilizers. While some may need to be mixed with water before use, others can just be sprinkled onto the soil. If you want a fertilizer that will save you time, you better go for the latter type.

Verdict

With this, we come to the end of our guide and we hope it will be easier for you to choose the right fertilizer for your garden now.

Before we sign off, we would like to recap our favorites from the list. The Espoma GSUL6 Soil Acidifier will be an ideal choice if you want a product to provide the necessary nutrition besides maintaining the right pH.

But, if you are looking for just a soil acidifier and can purchase a separate plant food product, Bonide BND56428 Soil Acidifier will be a great choice. On the other hand, Jobe’s Organic Soil Acidifier will be perfect if you are looking for a cost-effective but efficient product.

Let us know whether you agree with our verdict in the comments section below.

Till next time! Adios!
