The triangle plum usually changes the basin once every two years, generally before the Spring Festival Flower sprouts, after changing the basin, the root sprouts directly. But the larger potted plants need to be changed frequently, and they can also be changed when flowering. Because the big root of T. triangularis stored a lot of nutrients, and replaced 1 /3 of the soil, and cut 1 /3 of the fine heels, it had no effect on the growth and development of the whole plant.
Here's a brief introduction to the method of changing the pot of bougainvillea. Take the young seedling as an example: .
Prepare the soil and the basin to be changed before changing the basin. Choose the fertile soil with rich organic matter and loose soil, which can be mixed with a little wood bran or rotten leaf soil.
Generally, the new basin is larger than the old one, which is good for the growth of plants.
It's still a little tricky to take off the basin. As long as you clamp the root of the plant with your right index finger and middle finger, directly turn the basin upside down, buckle the drain hole with your left hand, and lift it out, the whole basin soil will come out.
As for the large basin, loosen the basin soil around the basin, reduce the weight and friction, and then grab the root to lift it out.
After the plant is taken out of the basin, part of the soil at the root shall be removed, and the soil near the root shall not be moved. The new basin can be planted with rubble. When going to the basin, add soil while planting, take the plant in the left hand, and add soil with the shovel in the right hand. Don't bury the soil too deep. It's easy to lose oxygen. If the plant is too large, it can be operated by two people.
After changing the basin, water it. If there is no drooping of leaves, apply a little light fertilizer and water immediately, and then maintain it normally.
