Once you plant them and get them to start growing, they should come back every year without hardly any effort or time from you.

Is hydrangea an annual or perennial?

Since hydrangeas come back on their own every single year, they would be considered a perennial plant.

There are actually many perennial plants that you can sprinkle throughout your garden to grow back each year on their own.

Do hydrangeas need a lot of water?

During the peak of their growing season, you can figure that they’ll need about an inch or so of water every week.

Besides that, they should be fine to get any extra water from the rain.

If you feel that it needs a tad bit more, use your best judgment.

How many hours of sun do hydrangeas need?

Hydrangeas like the sun and need it to grow. Make certain that you plant your plants somewhere that they’ll get about 6 hours of sunlight every single day.

Otherwise, you’ll be setting them up to not grow as well as they could, or possibly not at all.

What month do you prune hydrangeas?

This all just depends on when the plant is growing. Pruning it during the winter months will help it to be ready for growth during the next season.

But if you notice that it needs a pruning once it starts to bloom, you can prune it during the spring as well.

Where to Plant Hydrangeas

Hydrangeas thrive best in partial moist and well drained organic rich soil.

They need sunlight to thrive. So choose a place that gets sun in the morning and afternoon, but has shade in the late afternoon to prevent wilting and bleached leave in hot summer temperature.

How to Plant Hydrangea

Prepare the soil by adding organic matter if necessary.

Plant in a hole that is as deep as the root bulb and 2-3 times as wide to give the roots enough room to expand. Leave space of 3-8 inches between plants.

Be sure to loosen the roots before planting. Fill up the hole with soil and water very well.

How to Plant Hydrangea in Pots

You will need to use potting mix instead of garden soil when planting hydrangea in pots.

Use pots that have drainage holes and are large enough to allow the plant grow.

Make room for watering by leaving 2-3 inches between the top soil and the rim of the pot.

Hydrangea Care and Pruning

How to Water Hydrangea Plant

Most of them don’t really need major pruning other than removing dead stems and old flowers to keep the plant tidy.

Why is my hydrangea not blooming?

There are several factors that can cause your hydrangea to not bloom. It could be that you mistakingly removed a stem that would have bloomed or that you pruned at the wrong time.

It could also be that it’s not getting enough sunlight or that frost may have damaged the flower buds. Another factor is over-fertilization.

Cercospora is a type of disease that produces leaf spots on the bottom of the leaves that are often purple or brown in color.

You can try to stop this disease from happening by not watering the leaves whenever you’re watering the plant.

Try to water at the base of the plant instead.
