Rose fertilization in summer should be done like this
A little knowledge to share with you about rose fertilization in summer, here are some small experiences in plant cultivation. Let's learn about it together next.
The temperature has明显 risen in the past two days, and it feels like the hot summer is about to arrive. I even had the urge to turn on the air conditioner at noon. In Zhejiang, the temperature is already very high, and in some southern regions, it must be even hotter.
Summer is here, and for rose lovers, it's a difficult time. What kind of fertilizer should be used for roses in summer?
Roses will enter a semi-dormant state when it's very hot in summer, and their growth may stop or become very slow. Fertilizing at this time can easily cause fertilizer damage and lead to rose black rot.
However, if no fertilizer is used, and the roses are still growing, they will need nutrients, which can easily make the roses weak. This contradiction makes many rose lovers feel desperate. Should they fertilize or not?
Two steps for rose fertilization in summer. For fertilizing roses in summer, it is recommended to divide it into two steps: first, determine whether fertilization is needed, and then decide what kind of fertilizer is safer and more effective.
1. Determine whether the roses have entered dormancy.
Roses in summer do not necessarily enter a semi-dormant state, it all depends on the temperature. Some rose lovers have good heat prevention measures, and the temperature is not very high. In this case, roses often do not go dormant and remain in the growing period, which requires continuous fertilization.
Fertilize according to our normal growing period fertilization frequency.
In hotter environments, roses may enter a semi-dormant state, mainly showing "stunted growth," not growing or growing very slowly. Even after pruning, no new buds grow. Many rose lovers think that the roses are stunted, but in fact, it's because it's too hot, and the roses have entered a semi-dormant state.
Should fertilization be done for such roses?
Many people suggest stopping fertilization directly, but many rose lovers still hope that the roses can bloom earlier and use fertilizers to promote growth. The suggestion is to take a compromising approach: fertilize, but do not use fast-acting fertilizers.
2. What kind of fertilizer should be used?
When roses enter a semi-dormant state in summer, or when you are not sure whether your roses have entered a semi-dormant state, it is recommended to apply fermented organic fertilizer.
You can use fermented chicken manure, mix nutrients with a small amount of soil, and then sprinkle it directly on the surface of the flower pot. Each time you water, the fertilizer will seep into the soil with the flowing water. Fermented organic fertilizer has a gentle effect and is less likely to cause fertilizer damage. Moreover, organic fertilizer contains a lot of organic matter, which can maintain the looseness of the potting soil and prevent soil compaction.
What if there is no organic fertilizer?
If there is no fermented organic fertilizer or it is considered too dirty, you can use long-acting controlled-release fertilizer instead, magic fertilizer, or slow-release fertilizer.
Long-time followers should remember that I mentioned not to use slow-release fertilizer in summer, but it can actually be used, just not mixed with soil or used as a base fertilizer.
When using slow-release fertilizer as a top dressing in summer, use a small amount, which can be 1/3-1/2 of the usual amount, directly sprinkled on the surface of the potting soil without covering it with soil. This ensures a more lasting effect. If fertilizer damage is detected, the slow-release fertilizer can be removed immediately, which will not cause severe damage.
In summer, ensuring sufficient nutrient supply for roses can enhance their resistance, as fighting against extreme heat also requires energy. Appropriate nutrient supplementation in summer is also of great significance for the beautiful blooms of roses in autumn. To grow roses well, every step must be done right. Good summer management means that the mass blooming in autumn is not far off.
In addition to appropriate top dressing, there is a lot more to do in rose management in summer. Welcome to continue following.
