Do not delay with changing the soil.
When the light increases clearly and the plants start new growth, it is time to change the soils for the houseplants.
The work should not be delayed far into the spring.
– The time of soil change is just before the plant begins a vigorous growth phase. Then it will also grow the root system strongly, Kekkilä’s garden expert Mari Kaartokallio says.
Chairman of the Houseplants Association Paula Heino-Linnahalme says that the old people also rely on traditional knowledge in soil exchange.
– According to some, the optimal time for soil change is March 27-28. The old people’s calendar, for its part, says that the best time to change soils is from the new moon to the full moon, March 14-26.
It is not necessary to change the soil every year, as for some plants a new layer of soil on top of the root clump may be sufficient. In any case, fresh soil is necessary, as it gives the plant room to grow new roots, which will also allow the press to grow.
Choose the right mold, don’t forget the potting gravel
It depends on the type of houseplant what kind of mold is best for it. Many houseplants enjoy nutritious flower soil, but for cacti and succulents, for example, it is worth buying cactus soil.
– Especially large green plants, such as palms, like green soil, Kaartokallio says.
According to Heino-Linnahalmi, all soils, with the exception of cactus and seedling soil, need crumbs.
– My personal favorite is cheap flower soil, to which I add sand, gravel, bark crumbs, perlite, lecasora or curd moss.
In addition to the soil, it is a good idea to pick up gravel from the shop, which is placed on the bottom of the pot to give air.
– This ensures oxygen supply to the roots, Kaartokallio says.
The stones or gravel that were previously in the pot can also be reused, as long as you remember to rinse them in water, for example, wrapped in tights.
Choose a bigger pot
Before the soil change, the plant is watered well enough, for example the night before the soil change or hours earlier. This makes it easier to remove the pot and makes changing the soil easier.
If necessary, the plant is transferred to a larger pot. Cacti do not need to change pots every year, but many plants from tropical conditions do need them because they grow fast.
– The size of the pot should be estimated correctly. Even if the pot is too big, the plant may blow up, says Kaartokallio.
When removing the soil pack from the old pot, it is advisable to be careful. In the worst case, the root can be completely cut off. A disposable knife can be used to aid in removal.
– At the same time you can open the root system carefully. The roots are spread evenly on top of the new soil added to the bottom of the pot.
When the plant is in a new pot, new mold is pressed gently between the root pile and the pot. Mold is also added on top of the clump to prevent the plant from drying out.
There must be sufficient water between the edge of the pot and the soil surface.
The size of the pot should be estimated correctly. Even if the pot is too big, the plant may mouth.
Do not fertilize for two weeks
After the soil change, the plant is watered with room temperature water and transferred to a place of suitable brightness.
Soil exchange is a bit like a visit to the dentist for a plant. Sad and maybe sore, but necessary, Heino-Linnahalme says.
– The plant should be re-watered the next day, unless it is absolutely necessary to compact the soil. Spraying for a couple of days will help the plant recover from the shock.
Houseplants should not be given nutrients for two weeks after soil change. In summer, the plant must not be left unfertilized. Active weekly fertilization lasts from September to October.
– In winter, fertilization is enough once a month, Kaartokallio advises.
Useful plants on the windowsill
Households’ interest in gardening and especially in growing useful crops has increased, Biolan says in a press release. Interest has increased, especially among young adults under the age of 35.
– In busy everyday life, we want easy tips for growing a fresh crop on your own plate, garden advice Riikka Kerttula says in a press release.
Growing useful crops does not require a field or necessarily even a yard.
– The utility garden can also be set up on a balcony or even on a windowsill.
The Marttoja and Biolan Grow at Home campaign pages contain ecological education tips that are easy to implement with children.
