Recently, many flower enthusiasts are纠结, on one hand, the Chinese roses are getting weaker and weaker, showing a clear sign of starvation, on the other hand, it's too hot to apply more fertilizer, which is really troublesome!
Should we apply more fertilizer to the Chinese roses in summer?
About whether to apply more fertilizer, we must differentiate based on the growth condition of the rose plants. Any fertilization theory that ignores the actual state of the Chinese roses is impractical and should not be blindly followed.
If your Chinese roses are in a rapid growth state, you need to apply more fertilizer and increase the frequency and amount of application. For example, for climbing roses, summer is the疯狂 growth period of suckers. Should you apply more fertilizer? Without sufficient fertilizer and water, how can the suckers grow thick and long?
It's the same for shrub roses. The heat-resistant shrub roses also grow vigorously in summer. As long as they are growing, they consume fertilizer and water, so continuous fertilization is necessary.
Only when heat-sensitive varieties of Chinese roses show obvious growth stagnation should you stop applying fast-acting water-soluble fertilizers or nutrient solutions. Even for Chinese roses in a slow growth period, continuous fertilization is needed because high watering frequency in summer can easily lead to a lack of fertilizer in the potting soil. As long as they are growing, you need to apply fertilizer, just with different fertilizers depending on the growth conditions.
How should we fertilize Chinese roses in summer?
For Chinese roses in different growth states, we should use different fertilizers. For those in a vigorous growth period, we can use fast-acting fertilizers as in spring. And according to the watering frequency, we should appropriately increase the application frequency and reduce the concentration.
For example:
Should we fertilize Chinese roses in summer?
If in spring we apply a 1000-fold fast-acting fertilizer every 5 days when watering, then in summer, when watering is done every day, the fertilization schedule should be adjusted accordingly, applying fertilizer every 2-3 days and reducing the concentration to 1200-1500-fold.
This shows that in summer, we should focus more on "applying thin fertilizer frequently."
Many of our flower enthusiasts' Chinese roses are in a state of poor or slow growth in summer, and the fundamental reason for this is that the daily management has not been done well, such as overwatering leading to root rot or high fertilizer concentration causing burning of the seedlings. Green Plant Enthusiast Network suggests that新手 flower enthusiasts read the book "How to Grow Chinese Roses from Scratch" to quickly grasp the basic care techniques and avoid taking detours.
If the Chinese roses have already shown slow growth and are not in good condition, you should pay attention. If you can't control the amount of water-soluble fertilizer well, Green Plant Enthusiast Network suggests not to apply water-soluble fertilizer to the roots. Instead, you can spray nutrient solution on the leaves, adjusting the concentration according to the plant's condition. If the condition is general and there are many leaves, use 1500-fold; if the condition is very long, use 2000-fold, and spray every 3 days.
Of course, relying solely on foliar spray is not enough. To make Chinese roses recover quickly and grow and bloom again, you need to use long-acting fertilizers. You can shallowly bury fermented sheep manure around the pot, and for indoor balcony gardening enthusiasts, you can shallowly bury or scatter controlled-release fertilizers.
Note that you should use controlled-release fertilizers, not slow-release fertilizers. There is a difference between the two. Controlled-release fertilizers slowly release fertilizer and continuously provide nutrients for the Chinese rose potted plants (G-Y) without causing fertilizer damage.
Green Plant Enthusiast Network buries fermented sheep manure and controlled-release fertilizers shallowly around the roots in summer, so throughout the summer, there is no need to worry about a lack of fertilizer or fertilizer damage. How well the plants are cared for in summer will directly affect the number of flowers in the following spring.
