The 8 Best Types of Fertilizer to Keep Your Hydrangeas Blue and in Bloom

October 5, 2022


Hydrangeas are the most popular variety of shrubs for homeowners to plant in their yards. They are a favorite amongst those with a green thumb because of their beautiful colors and versatile sizes. As a result, there are many techniques known for keeping these plants healthy and happy. However, the real key element to keeping your hydrangeas beautiful and healthy is to give them the right fertilizer. As a result, in this article, we will cover the top fertilizers you can use to ensure that your flowers remain healthy and are in perpetual bloom.

Espoma Holly-Tone

This fertilizer is a complete hydroponic plant food designed for use in soil and soilless media. It is one of the best choices because it contains all the essential elements for healthy growth and flowering, including nitrogen, phosphorus, potassium, calcium carbonate, and magnesium sulfate. In addition, the formula contains humic acid, trace minerals, amino acids, water-soluble chelates, and fulvic acid.

Fish Bone Meal Fertilizer Powder

It is another good fertilizer for keeping your hydrangea blue because it contains fish bone meal and kelp meal, which provide trace elements that help keep blooms open longer than other fertilizers. You should apply this product once every six weeks during the growing season.

Espoma Flower Tone Plant Food

Espoma Flower Tone Plant Food is another excellent option for hydrangeas that need extra nutrients throughout the growing season. This product contains nitrogen and phosphorus, which will help promote flower growth and strong roots. It also contains iron, which helps prevent chlorosis (yellowing) of leaves by providing needed iron to plants when they need it most.

Miracle-Gro Indoor Plant Food Spikes

These spikes are a good choice if you have an indoor hydrangea that needs to be fertilized regularly. They're designed specifically for indoor plants and release nutrients slowly over time, so your plant doesn't get too much all at once and burn its roots or leaves.

The spikes feed for up to three months and only need to be inserted into the soil once per year, no more than one inch deep, so they're easy to use and won't harm your plant's roots if you accidentally hit them with your shovel while planting or mulching around them.

Dr. Earth Total Advantage Rose and Flower Fertilizer

This water-soluble fertilizer contains all the essential plant nutrients, including nitrogen, phosphorus, and potassium. It also contains magnesium and sulfur, which are necessary for plant growth. In addition, the package contains a mix of organic fertilizers derived from natural ingredients. These include kelp meal, fish meal, and rock phosphate.

The best way to use this product is to sprinkle it around the base of your plants when they're actively growing in springtime or early summer. You can also add it to your watering can if you're fertilizing potted plants or shrubs that have been transplanted outdoors into pots or raised beds indoors for winter.

Miracle-Gro Water Soluble Bloom Booster Flower Food

It is a product to use if you want to keep your hydrangeas blue. Miracle-Gro Water Soluble Bloom Booster Flower Food is:

• A water-soluble fertilizer that contains chelated iron makes it easy for the plant to absorb.

• This product provides your hydrangea with the nutrition it needs to stay healthy and beautiful.

• It also acts as an antiperspirant, which means it helps prevent your plant from losing too much moisture through its leaves.

The best part about using Miracle-Gro Water Soluble Bloom Booster Flower Food is that it doesn't have a strong smell or leave any residue on your plants. You can add it directly into your watering can or pour it directly into the soil around your hydrangeas, forming smart soil solutions without worrying about harming them.

FoxFarm Happy Frog Fruit & Flower Dry Organic Fertilizer

This organic fertilizer is a good choice for hydrangeas because it has a high phosphorus content. Phosphorus helps boost root growth and flower production in plants like hydrangeas. This fertilizer also contains trace elements like iron which helps ensure that your hydrangeas have strong roots and blooms throughout the growing season.

Natural Guard Organic Rose & Flower Food

Natural Guard Organic Rose & Flower Food is a balanced fertilizer for all flowering plants. It contains seaweed extract, which helps improve soil structure, drainage, and water retention. It also has humic acid, which helps to retain moisture in the soil. This organic plant food is an excellent source of nutrients, including nitrogen, phosphorus, potassium, and other trace minerals necessary for vigorous growth.

The Bottom Line

Hydrangeas are beautiful, useful plants, and using these best practices for fertilizer application will keep them looking their best. Unfortunately, there are so many different fertilizers out there that it can be overwhelming when deciding what type is right for your garden.

The main thing to remember when looking at other fertilizers is that the primary ingredients should be natural and organic. This way, you know that your plants will not only stay healthy, but your flowers will remain colored as well.


I believe in making the impossible possible because there’s no fun in giving up. Travel, design, fashion and current trends in the field of industrial construction are topics that I enjoy writing about.
