How To Fertilize Hydrangea

When you fertilize hydrangea, you are giving your shrubs the nutrients they need to stay healthy and produce blooms. Over time, the shrub will tell you when it needs fertilizer by producing fewer blooms. When that happens, apply a slow-release fertilizer.

How To Fertilize Hydrangea

Here is the complete process explained in detail on how to fertilize hydrangea:

Step 1:

1. Mix the fertilizer at a rate of 2 cups per plant and pour into the hole when you plant.

Step 2:

2. Apply an organic mulch around your hydrangea plants to keep in moisture, control weeds, and reduce soil erosion.

Step 3:

3. Fertilize again in early spring with a slow-release fertilizer at a rate of 1 cup per plant.

How to Grow Hydrangeas

Hydrangeas are one of the most popular flowering shrubs for their large, colorful blooms that last for weeks on end in summertime. They’re also one of the easiest shrubs to grow!

Here’s what you need to know about growing hydrangeas:


Full sun is best but they will tolerate light shade as well. If you want your hydrangea to bloom, give it full sun or as much sunlight as possible during the growing season (late April through September).


Water regularly but deeply during dry periods so that the water penetrates far into the root zone and doesn’t run off quickly. Mulch helps retain moisture by keeping water from evaporating too quickly from the surface of the soil and by keeping down weeds between plants and around their roots that compete for water with your hydrangea plants.


Soil should be moist but well drained, not soggy or wet, which can cause root rot problems and other diseases in hydrangeas. Give them a light application of compost or manure in early spring before new growth starts (in late March) and then again after they’ve finished blooming (in October). You can also use an organic mulch like shredded bark around their base to help retain moisture and keep down weeds between plants while helping feed your hydrangeas over time as it decomposes slowly over time into the soil beneath them!


Feed your hydrangeas every year after they finish blooming with a balanced fertilizer like 10-10-10 at a rate of 1 cup per plant mixed with water according to package directions (1/2 cup for smaller containers) and poured into holes made when you plant new ones or old ones that are being moved elsewhere in your yard (or just sprinkle it on top of soil around established ones). This encourages strong growth so they’ll produce more flowers next year! Wait until after bloom is over before fertilizing so you don’t encourage tender new growth that will only be killed by frost!


You can prune back some branches after bloom if you want to make them fuller or reduce their height if they get too tall for their location in your landscape design plan, but this isn’t necessary unless you have good reason to do it because they’re outgrowing their space – just cut them back to where there’s healthy new growth coming out near where you want them shorter – anywhere along the length of each branch is fine!

Pruning will stimulate more buds further up on each branch so it will fill out nicely next year! Cut stems back to just above an outward facing bud or leaf node – wherever there’s new growth coming out – on each branch since this is where all future stems will develop from this season on! The exception is if you want more than one leader growing up from each main stem; then cut back farther along each stem so there’s room for both leaders to grow without being crowded by one another once they reach maturity! Avoid cutting back too hard though because this can damage buds further up on each stem causing loss of flowers next year!

Also make sure not to prune off any flower buds that remain after bloom finishes because these may turn into seed pods later this season which should ripen next fall allowing birds who visit your garden later in summertime when most trees have lost their leaves some food sources for winter months ahead when natural food sources become scarce due to lack of fruit production during colder weather conditions outside your region…and more seeds produced means more flowers next year too!

So leave those flowers alone even if they’re already dead looking since these could still produce seed pods later this season…if not now then next fall instead…so let Mother Nature take her course here! But don’t worry because even if no seed pods form within these remaining dead looking dried flower stalks after all petals have fallen off naturally following bloom, these dead looking stalks won’t look ugly either since they’ll remain standing upright throughout winter months ahead providing some nice winter interest adding vertical height contrast against surrounding landscape

elements like snow covered groundcover beneath them plus evergreen trees & shrubs nearby beyond…not bad at all actually especially if there are no bare spots left behind when all else has shed its leaves come autumn time outside where you live…so let nature take its course here too so don’t worry about pruning off those remaining dried flower stalks even though

Tips for How To Fertilize Hydrangea

Here are 5 things to take care of with respect to how to fertilize hydrangea:

1. Use a fertilizer that has an NPK ratio of 5-10-5 or 10-10-10.

2. Apply the fertilizer once a month between April and September.


Interesting Facts About Hydrangea

Here are 5 things you should know about hydrangea:

1. Hydrangeas are a genus of about 30 species in the flowering plant family Hydrangeaceae, native to woodland in China and Japan, with a few species extending into southeast Asia.

2. The scientific name is derived from the Greek words “hydor” (water) and “angeion” (vessel), referring to the bladder-like receptacle that holds the nectar produced by the flower.

3. Some hydrangea flowers are blue, but most are shades of pink or white.

4. Hydrangeas are popular garden shrubs due to their large size and showy flowers, which range in color from white through lavender to deep purple; they can also be found in shades of pink, red and green. Most hydrangeas bloom from late spring through early fall, depending on climate and cultivar, with some blooming all year round where temperatures don’t drop below freezing for long periods of time. They can grow up to 25 feet tall with a wide spread as well as a vase shape or mounding habit. They have compound leaves with 3 leaflets which resemble oak leaves; this characteristic gives them another common name: oakleaf hydrangea . The leaflets have serrated edges and are typically light green with paler undersides on top while they turn dark red-purple underneath when exposed to sunlight. In autumn they may turn shades of orange or red before dropping off altogether after frost has killed them back down to ground level…which leads me right into my next point!

5. One of the things I love about hydrangeas is how dramatic they look in winter! Their bare branches stand out against snow covered trees and it makes for such a beautiful contrast! It also makes them easy to find when you want them back again come springtime!

The best fertilizer for hydrangea is organic. I use a homemade compost tea with my hydrangeas and they love it. You can purchase organic fertilizer but the compost tea works just as well and you can make your own.

How do I prune my hydrangea?

Hydrangeas can be pruned in several different ways, depending on what look you are trying to achieve. They can be pruned to a bush shape, an open vase shape or even a tree form.

The best time to fertilize hydrangeas is in early spring. This will give the plant a chance to store up nutrients before it blooms.

How much should you fertilize hydrangeas?

You should fertilize your hydrangea with 1/2 cup of a balanced fertilizer such as 10-10-10 once every two years. You can use a slow release fertilizer, but only if you have clay soil. If you have sandy soil, use an organic fertilizer that contains nitrogen, phosphorus and potassium instead.

Miracle Grow is a fertilizer that contains nitrogen, phosphorus and potassium. These are the three primary nutrients plants need to grow. Miracle Grow is not good for hydrangeas because it is only one of the three primary nutrients they need to grow.

Hydrangeas need to have all three of these elements in order to thrive. If your hydrangea does not appear to be thriving, then you should test your soil for these three elements. You can do this by having your soil tested by a local university or extension office or simply buy some testing kits at your local garden center.

Once you know what levels are in your soil, then you can add any needed supplements accordingly.

Epsom salt is a naturally occurring mineral compound composed of magnesium and sulfate. It’s commonly used as a laxative, but it can also be used to help fertilize plants, increase the uptake of nutrients in soil, and improve the overall health of plants.

When you use Epsom salt for hydrangeas, you are increasing the amount of magnesium that these plants can absorb from their soil. This results in stronger stems and leaves, better root growth, and improved blooms. In addition to helping your hydrangeas grow better overall, Epsom salt can also help them flower earlier than they normally would or bloom more abundantly.

How to Use Epsom Salt for Hydrangeas

In order to use Epsom salt for hydrangeas effectively, you will need to do two things: mix the Epsom salt with water and then apply it directly to your plant’s soil. Here’s how:

Mix one tablespoon of Epsom salt into one quart (1 liter) of water in a bucket or watering can. If you have large pots or planters with multiple hydrangea plants in them, make sure that you have enough solution for each plant. Pour this mixture into your watering can or sprinkler system and water your hydrangeas as normal using this solution instead of plain water. You may want to dilute the solution further if your hydrangeas are planted in large pots
