How to Keep White Hydrangeas White: What You Need to Know

How to Keep White Hydrangeas White: What You Need to Know

There are a few different ways to keep your white Hydrangeas looking fresh and white for as long as possible.

The first and most important way to keep your Hydrangeas white is to provide them with the perfect environment.

The Ideal Environment

Hydrangeas prefer bright, indirect sunlight. The best time of day for planting Hydrangeas is either in the morning or early evening when it’s still light out but before the sun starts beating down on the plant.

Next, Hydrangeas do not like extremely hot weather. The hotter it gets outdoors, the more your flowers will fade and turn a light green color.

If you live in a heat-prone area or have a lot of direct sunlight on your hydrangea bushes, you should invest in a sun shield. These can be purchased and put over your shrubs to protect them from the sun.

The third thing you should know about Hydrangeas is that they do not like wet feet. They need well-draining soil to ensure their roots don’t get waterlogged, which will cause the flowers to rot and turn an unsightly black color.

 It is important to plant white Hydrangeas in soil that has good drainage.

Last, Hydrangeas are thirsty flowers. They need a lot of water. You should remember to keep them watered daily during the hot summer months; especially if you have the sun shield installed because even with the shield, they will still get some direct sunlight and dry out faster.

The second way to keep your white Hydrangeas looking fresh is by trimming them.


You should remove any dying flowers as they fade to encourage new blooms. Trim the dead blooms down all the way to the base of the plant so that it can grow healthier and produce more flowers.

In addition, if you have a lot of brown, dead leaves on the bottom of your hydrangea that you don’t want to use in your flower arrangements, you can trim them off.

Be careful not to remove more than 1/3 of the plant at a time because it can do more damage than good.

The third way to keep your white Hydrangeas looking white is by fertilizing them.


Adding fertilizer to your Hydrangeas is a great way to help them stay healthy and vibrant. You should apply fertilizer at least once every two months during the spring and summer seasons, or more often if needed.

When applying fertilizer, you should mix it into the soil around the base of the plant and then water it generously.

Additional Tips for Keeping Your Flowers Looking Fresh

Below is a quick list of some other things you can do to keep your Hydrangeas nice and white!

1. Don’t over-water them. As mentioned before, Hydrangeas need water, but they don’t like wet feet either, so be careful with how much water you give them. If the soil is soaked, stop watering until it dries out a bit.

2. Don’t feed them with too much nitrogen fertilizer, especially in an acidic soil mix. If you notice the flower petals developing brown tips, you may want to cut down on the amount of fertilizer you give them until their next scheduled feeding time.

3. Prune your Hydrangeas in the spring. Remove dead or diseased canes and cut back on some of your shrubs to promote new growth and a bushy shape.

4. Leave the spent flowers on your Hydrangeas and remove them in autumn. This will encourage new flower growth and help keep the flower buds nice and tight.

5. Check for insects and other pests regularly. If you notice any signs of infestation, contact a professional pest control service to get rid of them the right way!

6. Of course, Hydrangeas don’t like extreme heat or cold, so try to keep them out of direct sunlight and protect them from frost during the wintertime.

7. Finally, make sure to plant your Hydrangeas in a suitable location and around plants they get along with. They don’t like competition for moisture, nutrients, or sunlight!
