How to fertilize a cactus and precautions for cactus fertilization
How to fertilize a cactusLet me tell you about the small knowledge of how to fertilize a cactus and the precautions for fertilizing a cactus. The following is a detailed answer by the editor for you.Cacti are slow-growing plants that require a lot of fertilizer to grow faster. Therefore, if you want to grow cacti well, you must first know how to fertilize them. I'm afraid most people don't even fertilize them when growing cacti, which can affect the normal growth of the cactus. Let's follow the editor to learn about the precautions for fertilizing cacti.[Part 1: How to fertilize a cactus]Cacti require different fertilizing frequencies in each season. Generally, in spring, when cacti are in their peak growing period, fertilizer is essential. Therefore, it is necessary to fertilize frequently, preferably every half month. This can provide adequate nutrients. However, in summer, when temperatures are higher, it is advisable to reduce the frequency of fertilization.You can choose to fertilize once every two months to make the cactus grow faster. However, in autumn, cacti enter another growing period, but the frequency of fertilization should be less than that in spring, so fertilizing once a month is recommended. But in winter, fertilization must stop, as it can affect the plant's normal growth or even cause root rot.[Part 2: Cactus fertilizing methods]There are two ways to fertilize cacti: applying base fertilizer and top-dressing. Base fertilizer is suitable before potting or repotting. You can mix a small amount of cake residue, bone meal, chicken and pigeon droppings into the soil, let them blend well with the soil, and the base fertilizer will be ready after a period of time. Top-dressing is suitable in spring and autumn, using diluted NPK compound fertilizer or organic fertilizers, but the specific amount of fertilizer should depend on the plant's growth.When fertilizing cacti, be careful not to let the fertilizer touch the ball. The amount of fertilizer should be less rather than more, as excessive fertilization can easily cause the plant to grow wildly, increasing the risk of frost damage to the new soft balls during winter.[Part 3: Precautions for fertilizing cacti]<1. Reasonable fertilization>So-called reasonable fertilization means applying fertilizer at the right time and in the right amount, with the correct type and concentration of fertilizer. Timely means fertilizing when the plant needs it the most and avoiding excessive fertilization, which can affect normal growth or even cause root rot. Therefore, everyone should pay attention to this.<2. Do not fertilize in special cases>Do not fertilize newly purchased cacti that are about to bloom or are blooming, cacti that have been lacking light for a long time, cacti waiting to root, newly emerged seedlings, newly potted cacti, cacti affected by pests, cacti under direct sunlight, and beginners growing cacti are advised not to fertilize.
