1. Don't rush to change pots for big rock paulownia in flowering period. What we bought is the big rock paulownia, most of which are in full bloom. Don't change pots for this big rock tree to prevent the leaves from withering and the flowers from falling. When can I change the basin for Dayantong? Generally, you can wait until the big rock tree blooms, and then it is not too late to change pots for it.
We need to change the pots for Dayantong. The flowerpots we use don't need to be too big, because they are too big to water easily and often accumulate water and rot roots. Dayantong is afraid of this, so he needs to use a smaller flowerpot. In addition, the material of the flowerpot is preferably a clay earthen basin with good water permeability and air permeability. Although this flowerpot is not beautiful, it is more flowery.
We can use loose and slightly acidic soil with good air permeability and smooth drainage as the soil for changing pots of Erythrina macrophylla. Generally, mixed soil of humus soil, peat soil and perlite can be used for breeding.
When we change pots for Erythrina macrophylla, we can remove some outside soil and put it on pots with protective soil. Moreover, when we put the pot, the bulbs need to be exposed, not all buried in the soil, because the new buds of Erythrina macrophylla grow from the bulbs. If too much soil is buried, the buds will rot easily after watering.
2. Big chimneys like warm environment, and the suitable temperature in the growing season is 10 ~25 degrees, but in different periods, big chimneys like different temperatures, for example, in the months of 1 ~ 18~25 degrees. Therefore, when it is extremely hot, it needs to be placed in a cool and ventilated environment. In order to cool down, water is often sprayed around the flowerpot.
When the year of 65438+ 10 comes, Dayantong's favorite temperature is 10 to 12. Therefore, in the environment of low temperature in winter, it is necessary to raise the temperature appropriately in order to make the big rock tree grow better and blossom.
3. I don't like strong sunshine. Dayantong doesn't like strong sunshine, but when the seedlings are young, they can have more sunshine, so that the seedlings will be more robust. When the sun is strong in summer, it needs to be placed in a cool and ventilated place. Also, in other growth periods, the light should not be too strong, otherwise the growth will be slow. Generally, in spring, autumn and winter, we can keep it in a scattered light environment. Proper shading can make the flowering period longer after flowering.
4. Pot-soaking method Watering flowers and leaves with big eyes has fluff, so I am afraid of water. Once there is water on leaves and flowers, it is easy to have rotten leaves and flowers. Therefore, we need to pay special attention when watering the big rock tree. Generally, pot soaking can be used, which can not only make the soil looser, but also keep the leaves out of contact with water.
In the rainy season, the big rock tree should be moved to a shelter from the rain to prevent the leaves from getting wet and rotting. There is still water in the flowerpot, which is easy to rot the roots.
5, thin and fat, the flowers with big eyes are bigger and spend a lot, so big eyes are more fat. When we plant Erythrina macrophylla, we can add a small amount of decomposed manure to the flowerpot, which can not only maintain the acidity of the soil, but also be beneficial to the growth of Erythrina macrophylla.
Then from leaf growth to flower bud formation, a thin decomposed cake fertilizer can be applied every 7~ 10 day. When the big rock tree grows buds, we can increase phosphorus and potassium fertilizer, which can make the big rock tree bloom, big and bright. Also, when fertilizing Erythrina macrophylla, you must not get the fertilizer on the leaves and flowers to prevent the leaves and flowers from rotting. There is also fertilization for Erythrina macrophylla, and it can also be fertilized by pot soaking to avoid fertilizer solution on leaves and flowers.
Dayantong is also called velvet flower. When it blooms, it is big and bright, which is a kind of flower that many flower lovers like. Don't change pots when the big rock paulownia we bought is in full bloom. It's not too late to change pots when it blooms. Then, through proper illumination, reasonable temperature, watering and fertilization, the seedlings of Erythrina macrophylla can grow strong and flowery.
