Its probiotic beneficial soil microbes and mycorrhizae help your hydrangeas draw more water and nutrients from the soil for better growth. Plus, they raise tolerance to a new environment’s stresses.

How To Choose The Best Fertilizer For Hydrangeas?
What Are The Types Of Fertilizer?
There are 3 types:
This is a concentrate, so you will dilute it with water or a ready-to-use product before using it. Whether you spray on the foliage or pour around the base, your hydrangeas can quickly absorb this type of fertilizer to boost nutritional value for your plant instantly. However, this isn’t an ideal choice for rainy areas. It is easy to be washed due to overwatering or rainfall.
This is the most common choice because it’s effortless to use. You can dissolve in the water, pour on the soil or sprinkle around the base. Moreover, they are known as time-release granules. Thanks to the polymer coating, they slowly dissolve to feed your plant. Granular fertilizer is a long-term supply of nutrients.
Like granules, this is also a long-term investment because it’s compressed and shaped into hardened spikes, which will slowly dissolve to offer nutrients for your plants within 2-3 months.
Although it’s straightforward to apply - you just need to bury the spikes in the soil near the plant base; this type of fertilizer can’t boost your hydrangeas immediately.
Do You Need Organic Or Inorganic Fertilizer?
Inorganic fertilizer is a combination of chemical and synthetic nutrients. It is formulated to result in a specific growing outcome. For example, an inorganic fertilizer with an increased acidity level can produce more abundant or larger blooms. Some inorganic fertilizers have time-released ingredients to slowly dissolve and feed your plant up to a few weeks or months.
Most gardeners love this choice more because it contains natural ingredients such as compost, poultry manure, and earthworm without chemicals. Though it isn’t as strong as inorganic fertilizer, it can improve soil health and nutritional value. For instance, organic fertilizer can provide both soil health and help heavy clay drain better.
What Is The N-p-k Ratio?
Any commercial fertilizer is labeled this ratio: N (nitrogen), phosphorus (P), and potassium (K).
You should invest in an all-purpose and balanced fertilizer like 10-10-10 (N-P-K) for hydrangeas because it contains an equal amount of nutrients. This is useful for the healthy development of foliage and bountiful blooms.
The different needs can make these numbers change. It’s better to buy a hydrangea fertilizer with an NPK ratio based on the nutrient deficiency of the soil:
Yellowing and wilting are the signs of lacking nitrogen. If your plant shows these features, it might require a high content of nitrogen. In this case, when choosing your fertilizer, make sure that N in NPK is the highest number.
High phosphorus content can boost the blooms of hydrangeas, while potassium develops roots and stems for your robust and vibrant hydrangeas.
A high concentration of phosphorus like (10-20-10) can raise the bloom’s quality and size.
What Is The Best Soil Type?
Hydrangeas work well in light soil because it provides your plant with better drainage. If you grow your hydrangeas in heavy or clay-like soil, organic fertilizers can help you improve this condition.

How do you fertilize hydrangeas?
What is the best time to fertilize hydrangeas?
You should fertilize most hydrangeas twice per year: in the early spring (May) and early summer (July). However, some types of hydrangeas have some special requirements as follows:
- Bigleaf hydrangeas require you to apply light fertilizer a few times during March, May, and June.
- Oakleaf and Panicle hydrangeas need to be fertilized twice: April and June.
- For smooth hydrangeas, you just need to fertilize once in late winter.
Should you fertilize newly planted hydrangeas?
You don’t have to fertilize newly planted hydrangeas for the first year.
Is Miracle Grow good for hydrangeas?
How do I increase hydrangea blooms?
Grow your hydrangeas in a place where they can get as much sunlight as they can tolerate getting more blooms.
Water your hydrangeas every one or two weeks, depending on the weather condition.
Apply and spread a 3-inch layer of mulch on the soil to maintain moisture and keep the root cool. This way is helpful with some hydrangeas, such as Hydrangea arborescens and smooth hydrangea.
Fertilize your hydrangea in the early spring when it is foliage production.
Use a pair of sharp pruning shears to deadhead a hydrangea throughout the flowering season as long as you don’t hurt the stems. If you don’t cut the dead flowers, they will go to seed.
Carefully prune the hydrangea for the next good season’s flowers. Just cut the flowers blooming on last year’s wood. Don’t prune in the late summer because you just remove buds at this time.
The best fertilizer for hydrangeas helps your plants develop entirely. Some nutrients help you transplant your hydrangeas to a new growing environment safely and conveniently, while others promote the development of roots, leaves, and flowers.
