The daylight of spring and summer are like rocket fuel for plants. Therefore, you can repot your houseplants at this time. They usually grow in two different ways. The first is about the leaves and flowers of the older plants. In the second, the roots grow underground and are mostly invisible. So late winter or spring are suitable times of the year when you want to repot your houseplants. Depending on the requirements for the transplant, you have several options.
Repotting indoor plants – facts worth knowing
The roots usually support all of the green growth above the ground. Sometimes you need to repot your houseplant into a larger pot for this reason. The old pot will be tight, while the new one offers more space for these roots. So healthy roots help create a healthy plant. Use our instructions when you repot your plants to create a pleasant atmosphere in your home.
Plants should therefore be moved to larger containers as they grow. If there is no more space for the plant’s roots, they can be tied to the pot. That is, the roots of the plant cramp up and form a tightly packed mass that inhibits growth. The most obvious sign of this is when you can already see roots on the surface of the soil. In this case, they will leak from the drain hole in the bottom of the pot.
If the plant appears to be stopping growth or has slowed it down, it is likely tied to the pot. If the plant is small, it is best to turn the pot on its side and take the plant out of the container. First of all, look at the roots. Are they rolled up in the bottom of the pot? If so, it’s definitely time to repot. Cuttings created by plants can overfill the pot and must therefore be separated and propagated in separate containers.
When should you repot indoor plants?
If your plant has just come home from the garden center, let it adjust to the new environment for a few weeks before repotting. The plants are usually in shock until they adjust to the new light, temperature, and humidity conditions. If you want to hide a simple plastic container, you can just put it in a planter.
Younger plants that are actively growing should be moved to larger pots once a year, for which you also use fresh soil. Repotting large indoor plants like the rubber tree or slow-growing plants can be done every two years. You notice this when these seem to grow out of their pots or appear top-heavy.
When a plant is thriving, you can be confident that it will be happy in its pot. When repotting green plants, it is a good idea to do so at the beginning of a phase of active growth. Repotting indoor plants that bloom in winter should be done in early autumn after the rest period.
Repot indoor plants step by step
The best way to remove the plant from its original container is to turn it on its side and carefully remove it from the pot. If the plant doesn’t move, you may need to tap the bottom of the pot on a hard surface to loosen the old soil. Otherwise you can also use a trowel or knife, being careful not to damage the root ball.
First of all, it is best to try to gently loosen the root ball. You can shake off excess potting soil to avoid damaging the tender roots. Use sharp scissors to remove brown, black, or visibly damaged roots. For heavily rooted plants or if you plan to reconstruct into a larger planter without repotting, cut off up to 3/4 of the root mass, starting with the bottom and sides of the plant.
As a new container, it is best to choose a clean new pot no more than 2 centimeters in diameter larger than the old home of your houseplant. Too much space slows down normal and healthy growth and can also lead to root rot.
If you are potting in a container without drainage, we recommend adding an approximately 1 cm thick layer of activated charcoal to the bottom of the pot. Some gardeners recommend a layer of pebbles on the base of a pot to improve drainage. However, it is unclear whether this will help. As long as the pot is drained, we exclude pebbles. Next, a layer of fresh potting soil is placed at the bottom of the pot so that the base of the plant is about an inch below the edge of the pot.
What to do after repotting your houseplants
After you have placed your plant in the new pot, fill it with soil until all the roots are covered and there is enough air there. Gently consolidate the soil to make sure there are no air pockets. However, be careful not to crush delicate roots. To begin with, you can lightly water the potting soil to keep the new soil moist, but don’t completely submerge it in water.
As mentioned above, plants tend to go into a shock phase after being replanted. However, don’t worry about it as this is perfectly normal. The plants can appear withered and thirsty. However, be careful not to water until about a week after repotting.
This will ensure that the roots damaged when you re-potted have healed. Move the plants to a cooler, shaded spot during the recovery period. Most potting soil contains fertilizer. So to avoid over-fertilizing and damaging your plant, you can stop fertilizing for about 6 weeks after repotting.
