When to repot ornamental grass?
Choosing the right time for transplanting ornamental grasses is very important. It depends on whether the plant will accept after repotting and whether it will grow nicely in the new place.
Unfortunately, there is no one universal date that I could give you. But I’ll show you when it’s best to overdo it. When choosing the best time to repot , you need to consider several factors.
Below you will find a list of the most important of them.
The type of ornamental grass and its influence on the date of transplanting
They can be divided into two main groups: spring grasses and summer grasses. Spring grasses are those that start growing in early spring and bloom in summer. This group includes, for example, Chinese miscanthus, giant stipa, or Japanese hakonechloa.
Summer grasses are those that begin to grow in the summer and bloom in the fall. This group includes, for example, pennisetum, panicum, or imperata. Spring grasses are best repotted in the fall, after flowering, and summer grasses – in early spring, before the start of growth.
The condition of ornamental grass and the date of transplanting
Before transplanting, you need to check that the grass is healthy and there are no signs of diseases or pests. If so, they should be combated beforehand or the diseased part of the plant should be removed.
In addition, you need to assess whether the grass is already too old. Also, remember that too thick grass needs rejuvenation or loosening.
When transplanting, you can divide it into several parts and replant only the healthiest and prettiest ones.
Influence of weather on transplanting time
Transplanting ornamental grasses requires appropriate soil temperature and moisture. Do not transplant grasses during heat, drought, or frost. This can cause the roots to dry out or freeze.
The optimum temperature for transplanting is around 15-20 degrees Celsius a. Soil moisture should be moderate and the soil should not be overwatered.
Repotting is best done on cloudy days. Choose morning or evening to avoid getting too much sun on your plants.
The best times of the year for repotting
As you can see, there are a lot of different factors to consider when planning a repotting date.
In the beginning, I wrote that the best time to transplant ornamental grasses is spring or autumn.
Let me now explain the benefits and challenges of these seasons. As always in life, nothing is black or white. Both seasons have their advantages and disadvantages.
Spring: benefits and challenges
Spring is the perfect time to repot ornamental grasses. The plant is dormant or just starting to grow.
Repotting will refresh it and improve drainage. It will also allow you to remove old and damaged parts that no longer look aesthetically pleasing.
If you plan to repot grass in the spring, choose only well-developed and healthy plants. Water them regularly and abundantly for the first few weeks after transplanting.
It is also worth using a fertilizer that will stimulate their growth and resistance.
Autumn: benefits and challenges
Fall is also a good time to repot ornamental grasses. It will allow you to refresh and rejuvenate plants, ensuring the attractiveness of the crop in the next season.
When transplanting grasses during this period, you must remember about possible frosts. They can damage the roots of grasses that have not yet had time to get used to the new place.
To prevent the term, you can cover the grass with a special fabric coat. Such a coat will allow you to maintain a slightly higher temperature and protect the grass from the wind.
An alternative is to tie the grasses with strings. Then only the outer stalks will be exposed to unfavorable weather conditions.
If you are afraid of frost, you can also use mulch. Cover the ground around the grass with it. It should protect the roots a bit.
The process of transplanting ornamental grass
Prepare your destination
Before you start transplanting, it is worth preparing a new place. It is imperative that you remove any weeds and other plant remains from it.
Also, remove any stones that will interfere with planting. Take care of the right soil for your type of grass. Make sure the soil has the correct pH. If not, adapt it to your grass.
It is also worth improving drainage and digging the place where the grass will be planted. This group of plants likes well-drained soil.
Repotting ornamental grass step by step

- Divide the clump into smaller parts with a knife or your hand, so that each of them has several healthy shoots and roots.
- Remove dead and damaged parts and weeds from the clump.
- Move the clump to a new place and dig a hole for it with a depth equal to the length of the roots.
- Place the clump in the hole and fill it with soil, compacting it lightly.
- Water generously and use a bark or straw mulch to prevent the soil from drying out.
After transplanting, it is worth taking care of the plant. Then it will definitely be accepted in a new place.
Maintenance rules after transplanting
After transplanting, you need to take care of the regular watering of ornamental grass. The soil should be constantly slightly moist, but not overflowing.
Adjust the frequency of watering to weather conditions.
Watch the grasses and see if they have started to wilt.
After a few days, apply an all-purpose grass fertilizer to revitalize the plant and boost growth.
