Summer's hot weather weakens the growth of roses , so proper watering and fertilization are essential for their healthy growth and high-quality blooms. So, how should you fertilize roses planted in the ground during the summer? Let's find out.
1. Fertilization time
Fertilizer should be applied in the relatively cool evening when the temperature is lower, which is conducive to plant absorption and less likely to cause fertilizer or pesticide damage.
2. Fertilizer Selection
In summer, it is recommended to use fermented organic fertilizers with mild fertilizing effects, such as fermented chicken manure or fermented sheep manure , and avoid using slow-release fertilizers to prevent fertilizer damage.
3. Fertilization methods
Dig a 30cm hole about 30cm away from the rose bush's roots. Then, apply fertilizer according to the size of the rose seedling. After digging the hole, add the chosen fertilizer directly to it and pour in a few spoonfuls of water. Do not cover the hole immediately; wait three to five days before covering it with soil. After that, you don't need to do anything else. The organic fertilizer will be slowly decomposed by microorganisms in the soil, producing a large amount of nutrients that will be readily absorbed by the rose's roots.
4. Fertilization frequency
Summer fertilization should follow the principle of applying diluted fertilizer frequently. Increase the concentration and frequency of fertilizer application; for example, if you fertilize it twice a month, now fertilize it three to four times. This way, it can absorb nutrients through water, and the absorbed nutrients are only minor, which can be quickly decomposed to promote the growth of the rose.
5. Remember to fertilize after rain.
In summer, some areas experience heavy rainfall, and each thorough rain washes away the fertilizer in the soil. After the rain, plants enter a very vigorous growth phase and their need for fertilizer increases, so remember to replenish fertilizer promptly after the rain stops.
6. Observe the growth carefully.
Before fertilizing, observe the growth of the rose plants. If the roses are growing slowly or are stunted, stop fertilizing.
