What fertilizer is good for rubber plants? Grow them fast this way
The rubber plant (Ficus elastica) is a plant with a relatively long growth cycle, so when people grow rubber plants, they all hope it can grow vigorously. However, during fertilizing, people do not know what fertilizer is good for rubber plants, especially in summer when rubber plants have a very large demand for fertilizer and water. If you want to know how to grow rubber plants fast, you usually need to fertilize them frequently during the growing season.
1. What fertilizer is good for rubber plants
Rubber plants grow very fast during the seedling stage, so their demand for fertilizer is naturally great. Therefore, during the growing period, rubber plants need to be fertilized frequently. However, many people do not understand what fertilizer is good for rubber plants. When fertilizing, you can usually apply a 10-fold diluted decomposed cake fertilizer water mixed with an equal amount of 500-fold potassium dihydrogen phosphate liquid fertilizer. As for frequency, fertilize once every 20 days in spring and autumn, and once every 15 days in summer.
Under your careful cultivation, the rubber plant will certainly grow vigorously. However, in early autumn, gradually reduce the frequency of fertilizing and watering, because this can promote solid plant growth and help it overwinter, so people must pay attention to this point during cultivation. After that, shorten the side branches once a year, and in 3 years you can obtain a round, full tree body 1.5-2 m tall.
2. How to grow rubber plants fast
1. Proper watering
The moisture level of the soil directly affects the growth rate of the rubber plant, so when watering daily, you must pay attention: you cannot water too much, and you cannot water too little. Especially in winter, if you water too much, root rot can easily occur. Only proper watering can let the rubber plant grow vigorously.
2. Accurate temperature control
When people grow rubber plants, they usually do not pay much attention to its growing environment. They may only know to place it somewhere with sunlight and it will grow vigorously, but reality is completely different. Although it can still grow at 30 degrees, its growth momentum will be greatly reduced, so the most suitable temperature for its growth is between 20 degrees and 25 degrees.
3. Prune frequently
Proper pruning can make plants grow more vigorously. The pruning time can be chosen in spring, cutting off pest- and disease-affected parts and weaker branches and leaves together, which can reduce the loss of nutrients. Therefore, when growing rubber plants, its growth speed is usually fastest in summer. You should create the best growing environment for it, and its growth rate will also increase. So if you want to know how to grow rubber plants fast, you must pay attention to this point.
4. It needs sunlight exposure
When growing it, you must choose a brighter place to put it, or a semi-shaded place is also fine. It is not suitable to be placed in direct sunlight, especially from May to September. In spring, autumn and winter, apart from the midday sun, it can be placed in the sun at other times, which is beneficial to its growth.
3. How to make rubber plants grow thick
1. Pinching
Pinching can actually also control the plant's growth. The pinching height should preferably be close to the diameter of the flower pot, better lower than higher, so the rubber plant will be more beautiful. However, when pinching, note that you only pinch off the topmost tender new shoots. You can pinch them off with your fingernails. After pinching, branches will grow, and the trunk growing thick depends on the years; the more you pinch, the more branches there will be.
2. Control fertilizing
Usually when people fertilize rubber plants, in order to make them grow fast, they keep increasing the amount of fertilizer, which often leads to excessive nutrients. As a result, although the rubber plant grows very fast, the branches are not very thick. So you must reduce the amount of fertilizer and lengthen the fertilizing interval to slow down its rampant growth momentum.
Conclusion: Through the detailed introduction above, I believe everyone now knows what fertilizer is good for rubber plants. In the process of growing it, if you want to know how to grow rubber plants fast, you still need to follow the methods described in the article. Only in this way can you truly grow a round and full rubber plant.
