What are the precautions for fertilizing bonsai and flowering plants
Bonsai
Fertilizing bonsai and flowering plants should be based mainly on organic fertilizers, applied in combination with chemical fertilizers. When applying, the following points should be noted:
1. Organic fertilizers are mainly used as a base fertilizer before transplanting or repotting, and must be fully decomposed.
2. Whether chemical fertilizers are used as a base fertilizer or a top dressing, over-fertilization must be prevented. Generally, 0.15-0.2 g of nitrogen (N) is applied per 1 kg of soil; the application rate of nitrogen fertilizer or compound fertilizer can be estimated on this basis. Specifically, it should be based on the size of the pot and the size of the plant; usually 10-30 granules of compound fertilizer are applied per pot each time.
3. When fertilizing, chemical fertilizers should not be placed at the base of the roots, so as to avoid burning the roots and to avoid hindering absorption; the fertilizer should be applied at the edge of the pot; do not scatter the fertilizer on the leaf surface, to prevent burning the leaves.
4. Once fertilizer burn occurs, water promptly or repot, replacing part or most of the potting soil with new soil.

Precautions for fertilizing flowering plants

Fellow flower growers all know that if you want to grow flowers well, fertilizing is indispensable. Everyone surely thinks fertilizing is easy! You just sprinkle the fertilizer into the soil and that's it. In fact, this approach is wrong. Fertilizing flowering plants is quite particular, so when fertilizing flowering plants, you need to know these precautions.
① When fertilizing flowering plants, apply small amounts but more frequently.
② The inorganic fertilizer applied to flowering plants must not be broadcast or come into contact with the base of the plant stems.
③ Organic fertilizers can only be used after being composted and fully fermented and decomposed.
④ In summer, when plants grow vigorously, fertilize more.
⑤ In winter, when plants grow slowly, fertilize less.
⑥ After heavy rain, or when the plant's leaves are yellow-green and dull, apply a supplementary fertilizer promptly.
⑦ For flowering plants with corms or fleshy stems, because they can store nutrients and have fewer roots, the top-dressing amount can be less than the normal fertilization amount.
⑧ For fibrous-rooted flowering plants, because they are planted in loose media, top dressing should be applied in small amounts but more frequently, at 1/4 to 1/5 of the normal amount.
⑨ Large-leaved shade-loving foliage plants grow rapidly and have well-developed root systems, so they need more fertilizer.
⑩ For bonsai, the top-dressing amount should be small and the fertilizer effect should be long-lasting, mainly using bone meal and cake fertilizer.
So you see, fertilizing flowering plants well is also a subject of study! Have you learned it?
