Teach you to make your own jasmine, gardenia, rhododendron and camellia fertilizer, which are simple and practical.

When we raise these flowering plants, such as rhododendron, gardenia, jasmine, camellia and so on, we often hear people suggest applying alum fertilizer to them. What on earth is alum, fertilizer and water? What effect can it have on these flowering plants? How to make alum fertilizer water at home? Today, let's solve them one by one.

Friends who often grow flowers know that flowering plants such as rhododendron and gardenia are mostly transported from the greenhouse of the southern base. Due to the climatic conditions and regional differences between the south and the north, the soil acidity and alkalinity are different between the south and the north. The soil in the south is sour, while the soil and water quality in the north are alkaline. Flowers from the south come to the homes of flower friends in the north, and there may be no change in the short term. Over a long period of time, yellow leaves will wilt. Apart from being related to aquaculture management, most of the reasons are due to the lack of soil acidity. And the flower friends invented the retting alum fat water just to solve this problem.

Alum fertilizer water is a kind of acidic fertilizer, which can just solve the problem of soil alkalinity in the process of cultivating south and north flowers. Applying appropriate amount of alum fertilizer water in the peak growth period of acidophile plants can make the plant leaves thick and green and the flowers big and colorful.

There are two ways to make alum fertilizer and water: 1. Ferrous sulfate, dried dung, cake fertilizer and water are prepared according to the ratio of 1: 3 to 5: 100, put into an airtight plastic container, and become a black-green liquid after full fermentation. In general, families grow flowers and use abandoned old oil buckets. If possible, you can expose yourself to the sun and open the bottle cap every few days to deflate to prevent the bottle from bursting. It usually takes 1 month in summer and 2-3 months in winter.

two。 Fermented mixed organic fertilizer such as Amoy rice water, fruit peel enzyme, bean cake water, etc. add a small amount of ferrous sulfate, is also alum fertilizer water. The rotten alum fertilizer water not only contains sufficient humus, but also slightly acidic, and watered the flowers 20 times with water, which not only replenishes the nutrients to the flowers, but also can quickly alleviate the chlorosis caused by soil alkali or iron deficiency. When fertilizing, remember to apply thin fertilizer frequently, not too much, so as not to burn roots. Give it a try!
