The first thing to know about growing hydrangeas is that they are not just for planting in the ground. You can grow them in containers and windowsill gardens as well.

You will want to keep your plants near a window, so be sure you don’t place them where they are blocked from sunlight by other buildings or trees. This blog post will give you tips and techniques on how to use baking soda to grow hydrangeas!

Is Baking Soda Good for Hydrangeas?

Yes. Baking soda can be used to fertilize a hydrangea plant and help it grow. It contains 24% nitrogen, which is beneficial for the soil microbiome of the plants that are going to consume it.

How to Use Baking Soda To Grow Hydrangeas?

Step One: Choose a location and select the type of container you want to plant your hydrangea in.

Step Two: Purchase or make an organic potting soil mix, preferably made from composted forest mulch (choose one that is pH-neutral). You will need about four cubic feet for every 100 square feet of planting area.

Step Three: Fill the container with soil, a little less than one inch from the top.

Step Four: Place your hydrangea plant in the pot according to instructions on packaging or that you can find online.

Step Five: Water thoroughly after placing plants in their containers and making sure they are also watered each day for best results.

Step Six: Add baking soda to the soil, if desired.

Is Baking Soda Good for the Hydrangea Roots?

Yes. Adding baking soda to the soil around a plant can help improve water retention and root growth for your hydrangea, which will lead in turn to better leaf production.

Can Baking Soda Reduce Fungal Disease?

Yes. Baking soda is an organic fungicide with anti-fungal properties that can help prevent fungal disease from attacking your hydrangea plants, so it’s a good idea to use it every time you water the plant or give them fertilizer.

How Much Should You Use?

It depends on how much baking soda you want to add to your plants. One tablespoon per gallon of water is a good amount for most circumstances, but you can use two tablespoons if the plant has been growing poorly and looks like it needs an extra boost.

How Long do I Continue To Use It?

For the best results with hydrangeas, it’s recommended that you use baking soda for at least six months.

Benefits of Baking Soda for Hydrangeas

  • Baking Soda helps to alkalize soil pH levels so the plant isn’t struggling with an acidic environment.
  • It can help prevent the fungal disease from attacking hydrangea plants and make them more resistant against it in general.
  • Fertilizing your plants with baking soda will promote root growth, which will help improve leaf production.
  • It is an organic fungicide with anti-fungal properties that can be used to kill any fungal disease on your hydrangea plants.
  • Baking Soda provides 24% nitrogen, which helps the soil microbiome of plants consume it grow and flourish.

Will it Make my Hydrangeas Flowers Change Color?

No. Baking soda will not make any color changes to your hydrangeas and is safe for plants of all types, including those that you are trying to keep a specific hue on them (like blue flowers).

The Right Time To Plant Hydrangeas

You’ve found your perfect location, picked out a container, and purchased organic potting mix—but what about when is the best time of year to plant hydrangeas? The springtime is a popular season for planting.

How To Care For Hydrangeas

The following are basic care instructions for hydrangea plants:

  • Fertilize with an organic fertilizer. This should be done at least once a year, but you can use it as often as every four months if desired. Look for one that contains some nitrogen and phosphorus; these will help the plant grow and bloom.
  • Water your plants often, especially during dry or hot periods of time. The soil should be moist but not wet; if you see water standing on top of it, then this means that there is too much moisture in the area and more watering will need to be done.

How To Keep Hydrangeas From Blooming

Hydrangeas should be pruned every year, and you can do this in either late winter or early spring. When you are trimming the plant, take off at least a third of its branches and discard them. You will also want to clip back any dead flowers that remain on the shrub so they don’t attract pests.

Hydrangeas in Containers vs Hydrangeas in Ground: What’s Better?

There is no definite answer as it really depends on what you want and what you have in terms of space. Many people prefer to grow their hydrangeas indoors, at a window, or near an outdoor area with plenty of light exposure.
