Caring for hydrangea in a pot

Hydrangeas grown in pots require the same care as those grown in the yard. They just need more fertilizer and water, as containers dry out much faster than the ground. Here's what they need:

a light

Hydrangeas need morning sun and afternoon shade to protect them from drying out, and potted hydrangeas are no exception. Growing hydrangeas in pots means that you are not limited to growing them in just one place. You can move the pot to the place you need to get more or less light. Just make sure they get four to six hours of sunlight per day or dim light throughout the day.


When you grow hydrangeas in pots, you don't have to worry about poor soil. You are using a brand-name potting soil. Choose a high-quality, well-draining mix with compost mixed in and keep it moist. Add a layer of mulch to retain moisture.


There is no need to worry if the container's soil is too dry or too wet. Simply water the pots in the morning until excess water comes out of the drainage holes. Then check them again in the afternoon. If wilted, water. Watering potted plants takes much less time, because all the water goes directly to the roots, rather than running off the surface of the soil.

Temperature and humidity

Hydrangeas like moderate temperatures from 50 to 80 degrees Fahrenheit, and do not like heat. They tolerate even high humidity but do not like a dry climate. Move the container of hydrangeas to a location where they will get more shade in the afternoon and water them if they are wilted.


Potted hydrangeas need a slow-release granular fertilizer in the spring. When planting hydrangeas in pots in the spring, use a potting mix that contains a slow-release fertilizer or add some to the soil before planting. In the second year, apply a slow-release fertilizer to the soil surface and keep it off the plant's branches. Repeat every four to six weeks and stop in late summer to discourage growth that will not have time to harden off before cold weather sets in.

Types of hydrangeas for pots

  • “Tuff things” (Hydrangea serrated) is a thriving mountain hydrangea, a good variety for pots. They grow shorter and more compact and offer the same color-changing ability as French hydrangeas. It is very durable, and most selections feature clusters of lace flowers.
  • “Invincible Wei White” (Hydrangea arborescens) is a smooth dwarf hydrangea that grows 1 to 2.5 feet tall and wide. The white flowers bloom from early summer through fall and change from pink to cream as they age.
  • “Little Lime” (Hydrangea paniculata) is a miniature version of the Limelight Hydrangea. It is a cluster hydrangea with clusters of green flowers that turn pink in fall. It grows to 3-5 feet wide and tall.


Different types of hydrangeas need pruning at different times, depending on whether they thrive on old or new wood. Varieties that thrive on older growth, such as bigleaf and mountain ones, should be pruned in the summer after they bloom, if necessary. Species that thrive on new growth, such as curly and smooth varieties, can be pruned between late fall and early spring. During the growing season, faded hydrangea flowers can be pruned to encourage new growth.

Propagating hydrangea for pots

Most of the hydrangea varieties suitable for containers are cultivars. It is illegal to propagate branded or patented plants.

Potting and repotting

Make this process easier on yourself by choosing a large pot that is at least 14 inches wide at the top and make sure it has drainage holes. The more soil the pot contains, the less often you should water and fertilize. Also choose a rolling selection that thrives on current and last year's growth. This way, if you get into the habit of pruning and overdo it (most hydrangeas need very little pruning), you'll still get flowers even if you cut off some of the flower buds.

Use a high-quality potting soil that contains a slow-release fertilizer and mix it in with some compost. Loosen the edges of the roots, then place the hydrangea in the pot, leaving 2-3 inches of space above the root ball. Fill in the surrounding area with more soil to fill it in and pat it down. Water well and add a layer of mulch to the top. The plant will need to be repotted in three to five years.


Potted hydrangeas should be kept outside in the winter so they can experience seasonal changes and go through a dormant period, but they may need some extra care. Move the pot to a location opposite the house or other structure where it will receive sun and rain but is protected from harsh winds and frost. In temperate climates, potted hydrangeas can tolerate winter weather, just be sure to water them less frequently. In cool areas, water the container well in the fall and add a layer of mulch.

Common plant pests and diseases

Pest problems are not common for hydrangeas, but they may be affected by spider mites, aphids and Japanese beetles. Treat infestations with insecticidal soap.

Hydrangeas are susceptible to diseases such as powdery mildew, wilt and leaf spot. The likelihood of fungal diseases increases when the plant is crowded and there is not enough air flow. Also water your hydrangea from its base rather than from the top to avoid getting its leaves wet. If you see yellow or brown leaves or spots, treat the plant with a fungicide.

How to make potted hydrangea bloom

Different types of hydrangea have different flowers. Lacecap varieties have flowers surrounding small buds, mauve flowers are large and round, and oak-leafed hydrangeas have cone-shaped clusters. If your hydrangeas don't bloom in pots, there are several reasons why. Insufficient sunlight can be a factor. Check the plant's exposure to sunlight and be sure to place the container in a location that gets four to six hours of sunlight with afternoon shade.

Also make sure to water them frequently, as containers are prone to drying out. Pruning at the wrong time can reduce flowering. Prune after the plant blooms to avoid removing the following season's flowers. Too much water can also lead to a decrease in flowering. Make sure the soil is evenly moist but never saturated.

Common problems with potted hydrangeas

Hydrangeas grow easily in pots, problems are usually due to growing conditions and can often be adjusted. If the leaves wilt or turn yellow or brown, this is a sign to evaluate plant care.

Curling leaves

This is often a sign that temperatures are too high for hydrangeas. Wilted leaves often regain their appearance when temperatures cool and there is shade in the evening. If the leaves are curled or wilted, try moving the container to afternoon shade and give the plant more water if the top inch of soil is dry.

Leaves turn yellow

Check the soil to make sure it is not too wet. Wet soil can cause rot, and overwatering can cause the leaves to turn yellow. Skip watering until the top few inches of soil are dry. Use well-drained soil and a pot with drainage holes to avoid wet soil conditions.

Leaves turn brown

If your hydrangea leaves are turning brown, it may be due to exposure to underwater or too much sun. Water deeply several times a week and add a layer of mulch to the top. Too much direct sunlight can cause leaf burn. Move the container so it is shaded from the afternoon sun. It can also indicate that too much fertilizer has been used. If in doubt, water the plant to remove excess fertilizer.

The hydrangeas are back in Grumpy's good graces. Good pots make happy plants.

Frequently asked questions

  • Can potted hydrangeas grow indoors?

    Potted hydrangeas will live indoors for a short time, but they need to be outside to experience seasonal changes. Potted hydrangeas may be kept indoors but do not last long. They are temporary plants grown to flower very quickly, and since they are grown in a greenhouse, they are not very cold tolerant. Hydrangeas do best when they go through a natural dormancy period caused by cool temperatures.

  • Can potted hydrangeas survive frost?

    Hydrangeas can tolerate cold temperatures, but may be affected by frost. Frost can damage any new shoots, but will not severely harm the plant.

  • Do hydrangeas grow better in the ground or in pots?

    Hydrangeas do very well in pots. If your space is too small to grow hydrangeas in the ground or your soil conditions will not support them, a container is a good option. Use well-drained soil and make sure the plant gets plenty of water and morning sun.
