What are the secrets to fertilizing Chinese roses?
Chinese roses have large and bright flowers with numerous varieties. Well-maintained Chinese roses can bloom every month and are deeply loved by many rose enthusiasts. Experienced rose growers know that Chinese roses are "heavy feeders" and require a lot of water and fertilizer to bloom well.
Due to the eagerness to grow healthy Chinese roses, many enthusiasts apply all kinds of fertilizers excessively without paying attention to the amount or concentration. As a result, the roses not only fail to grow as expected but may also suffer from various fertilizer injuries and damage, failing to bloom and even facing the threat of death.
Although Chinese roses like fertilizer, it is not advisable to fertilize them randomly. When fertilizing Chinese roses, remember the "3 dos and 2 don'ts" principle to ensure they absorb adequate nutrients without suffering from fertilizer damage, thus enabling them to burst with strong shoots and bloom profusely!
1. Apply base fertilizer
Rose enthusiasts all hope that their plants will produce many strong shoots, as these new branches emerging from the soil are extremely vigorous and are the main force for blooming. To encourage many strong shoots, you must first ensure that the soil is sufficiently fertile.
Spring is the peak growing season for Chinese roses and the best time for them to produce strong shoots. Therefore, after pruning the roses in winter, experienced gardeners apply base fertilizer by burying fish intestines and kitchen scraps in the potting soil to increase its fertility.
Those without composting experience or those growing roses on indoor balconies should not try composting. Improper composting can easily cause root burn and create an unpleasant smell in the house. It's better to use granular slow-release fertilizer for the base. Dig small holes around the edge of the pot and sprinkle the granules evenly. The slow-release fertilizer will gradually release nutrients, enhancing the soil fertility, and once the roses resume growth in spring, they will burst with strong shoots, making blooming a breeze!
2. Apply thin fertilizer frequently
Although Chinese roses like abundant fertilizer, they should not be supplied with it unrestrictedly. Over-fertilizing can cause an accumulation of nutrient solution in the potting soil, leading to root damage. Therefore, always apply thin fertilizer frequently!
During the growing season, dilute a specialized organic nutrient solution for roses with water at a ratio of 1:1000 every 10 days and slowly pour it around the edge of the pot. This allows the roses to absorb an appropriate amount of nutrients continuously, ensuring continuous growth and blooming!
3. Water promptly after applying liquid fertilizer
After applying liquid fertilizer to Chinese roses, remember to water them with clean water early the next morning. This is known as "return water." Promptly watering with return water allows the accumulated fertilizer solution on the surface of the soil to渗透 into the deeper soil, helping the roses absorb nutrients and avoiding the risk of root damage from excess fertilizer.
4. Do not apply foliar fertilizer after bud formation
Besides applying root fertilizers, many enthusiasts also like to apply foliar fertilizers to Chinese roses. It is best to apply foliar fertilizers during the leaf expansion stage. Dilute a high-nitrogen and potassium fertilizer solution with water, pour it into a spray bottle, and evenly spray it on both sides of the rose leaves. Absorbing rich nitrogen and potassium fertilizers helps the roses develop strong roots, green leaves, and continuous growth of lateral branches, preparing them for flower bud differentiation.
However, once the Chinese roses have developed buds and the buds are half-open, it is best not to spray foliar fertilizers to avoid the fertilizer solution from accumulating in the flower buds, which could cause bud damage and prevent us from seeing beautiful rose flowers.
5. Do not fertilize after the flowers are fully open
After the rose buds have fully opened, do not fertilize them. Continuous nutrient supply will cause the roses to undergo continuous physiological metabolism, accelerating petal fall, which is not conducive to long-term appreciation. Therefore, once the roses have fully bloomed, we should stop fertilizing to extend the flowering period, allowing us to enjoy the beauty of the roses for a longer time!
When growing Chinese roses, always remember the "3 dos and 2 don'ts" of fertilizing to avoid mistakes, ensuring the roses have adequate nutrition, burst with strong shoots, and bloom continuously!
