What fertilizer is good for longevity flowers

Overview of Kalanchoe fertilization

Kalanchoe is a plant of the genus Kalanchoe in the Crassulaceae family. It prefers a warm, slightly humid and sunny environment. It is not cold-resistant. The suitable temperature for its growth is 15-25℃. It is drought-resistant and has no strict requirements on soil. It is suitable for growing in fertile sandy loam.

Generally, peanut shells can be used to fertilize Kalanchoe, because they contain a lot of oil and other nutrients. After composting, they can be converted into nitrogen, phosphorus and potassium organic fertilizers, which can provide sufficient nutrients for Kalanchoe, and can also effectively improve the looseness of the soil and promote vigorous flowering.

What fertilizer is good for longevity flowers

Normally, it is better to apply potassium dihydrogen phosphate foliar fertilizer to Kalanchoe, especially after pruning the plant, its new branches grow more lush, and the leaves are thick and dark green. At this time, applying potassium dihydrogen phosphate can promote the growth of flower buds. Under normal circumstances, it can be applied every 7-10 days.

How to fertilize Kalanchoe

When fertilizing the Kalanchoe, you can poke a few small holes on the edge of the pot away from the root system, then put the fertilizer in evenly and cover it with soil. Be careful not to let the fertilizer touch the root system. With watering, the fertilizer can be decomposed and provide nutrition for the Kalanchoe.

1. Fertilization in spring

Spring is the flowering period of Kalanchoe. If you fertilize the plant at this time, it will easily cause it to sprout new buds. The new buds will compete with the flowers for nutrients, causing the flower buds to fall off and the flowering period to become shorter, so it is not advisable to fertilize at this time.

2. Fertilization in summer

It is better to choose June to fertilize in summer. You can use fertilizers containing nitrogen, phosphorus and potassium, or you can use your own fermented cake fertilizer and soybean water, all of which can promote better growth of plants.

3. Fertilize in autumn

It is better to apply fertilizer in autumn around October. This is the time when the Kalanchoe sprouts flower buds. You should apply phosphorus and potassium fertilizers. You can apply Huaduoduo No. 2 or potassium dihydrogen phosphate to promote the germination of flower buds.

4. Fertilize in winter

Around December in winter is the flowering period of Kalanchoe. Stop fertilizing at this time. If you fertilize it at this time, it may cause fertilizer damage, which will affect the normal growth of the plant.

Points to note when fertilizing Kalanchoe

1. When fertilizing Kalanchoe, be careful not to apply too much or too concentrated fertilizer, because this can easily cause fertilizer damage, which can affect the growth of the plant at the very least, and can even cause root burn and death.

2. To prevent root burn caused by fertilizer, when applying phosphorus and potassium fertilizers to Kalanchoe, do not use potassium dihydrogen phosphate and Huaduoduo No. 2 together, because they are both high-phosphorus and potassium fertilizers, and using them together will easily cause fertilizer damage. They can be used alternately.

3. If too much fertilizer is applied to the Kalanchoe, causing the soil to be too fertile, it will easily cause the leaves to turn yellow. At this time, a large amount of water is needed to dilute the fertilizer and drain the excess water and dry it.

4. Kalanchoe is a short-day plant and is sensitive to photoperiods, so after fertilizing it, you need to pay attention to providing it with short-day light, about 8-9 hours of light per day.
