Transplanting hydrangeas: When is the right time to change the location for garden hydrangea and hydrangea in the container?

Whether in a container or in an ornamental garden, hydrangeas only feel comfortable when they remain in the same place for several years, and they usually do not tolerate a change of location well. In some cases, however, you can not avoid it: Unless it’s because the garden is newly planted, or because the plant is infested with pests, or perhaps because a tree next to it is crowding out the shrub. If you want to transplant hydrangeas, there are a few things you should keep in mind. With these tips, the hydrangea is guaranteed to tolerate the change of location well.

When to transplant hydrangeas: Timing is critical to success

There are several reasons why you might want to transplant your hydrangeas. In the case of garden hydrangea, choosing the right location is especially important. If the shrub produces few or no flowers, if its leaves are always wet and if it hardly grows, then these are signs that it is not comfortable in its current place. It is also advisable to change the place in case of over-fertilization.

However, since any transplanting stresses flowering shrubs, there is a risk that the perennials will die. Especially if you transplant them at the wrong time.

As with all plants, the rule of thumb is that it’s best to transplant hydrangea during the dormant season. There are differences, however:

  • The farmer’s hydrangea and the plate hydrangea are best transplanted at the end of the dormant season, around February to April. An important prerequisite for this is that the permafrost has already passed.
  • The ball and panicle hydrangeas, on the other hand, are transplanted in late summer to early fall (late August to late September), that is, immediately after the end of the flowering period and before the beginning of the dormant season.
  • Potted plants are transplanted from the pot into the garden from early April to mid-August.

Transplant hydrangeas, but in August: is it possible? Can hydrangea tolerate a change of location in the summer?

For now: transplanting in summer is only an option in exceptional cases. In this case, good preparation is the key.

1. you should transplant hydrangeas on a cloudy day.

2. experts advise against transplanting the shrubs during hot spells. This could cause the plant to lose its flowers and leaves and even die.

3. maintenance pruning can be omitted this year, it would further stress the hydrangeas and stress makes them more susceptible to diseases and pests.

4. water hydrangea bushes abundantly even after the flowering period is over. If the plant forms flowers again, it is an indication that they are comfortable in a new location.

Potted plants can cope well with a change of location in the summer. In exceptional cases, ball and panicle hydrangea also tolerate the change of location well and quickly grow in the new place in the garden.

Transplanting hydrangeas: What location, what soil? Step-by-step instructions

Hydrangea transplanting tips in summer

1. choose the right location. Especially in summer and autumn hydrangeas need a lot of moisture and can not tolerate drought well. Therefore, the best locations are sunny and partial shade, well protected from wind and heavy rain.

Loosen the soil and work in leaf humus. Remove stones. Measure the soil pH or send a sample to the lab. Hydrangea prefers slightly acidic soil. If needed, you can improve the permeability of the soil by mixing in sand. This will then allow the orchids to root through much faster.

3. dig a planting hole and pour about 10 liters of decalcified tap water into the hole.

After the end of the flowering period, you can easily transplant the garden hydrangeas (ball and panicle hydrangea). To do this, proceed as follows:

  1. Cut the hydrangea after the flowering period. The plant will then need two weeks to recover from the cut. Only then can you repot it.
  2. Hydrangeas are shallow rooted, so do not dig directly around the visible area of the root system. Be very careful when doing this so you don’t damage the fine roots. Do not remove the soil at the roots.
  3. For larger shrubs, you can loosely tie the shoots together so you don’t damage them when planting out and planting in.
  4. Place the garden hydrangea in the planting hole and cover the roots with soil.
  5. Water the freshly transplanted hydrangea abundantly.

Planting hydrangeas from pot in the garden in August

Potted plants are particularly sensitive to frost and must be planted in the garden no later than the beginning of August so that they grow well until the first frost. They prefer an off-sun, absolutely wind-protected and preferably still warm location with west or south orientation.

1. dig a planting hole twice as wide as the diameter of the container. Loosen the soil, work in leaf humus and if needed – sand. Pour about 10 to 14 liters of decalcified tap water into the hole.

2. carefully remove the plant from the container, leaving at least part of the potting soil at the roots, and immediately plant the hydrangea in the garden.

3. place the container plant in the hole. Cover the roots with soil and water the plant abundantly.
