What to Do When the Tips of the Rose Bush Shoots Turn Black
When the tips of the rose bush shoots turn black, you can spray the shoots with omethoate solution, doing so once a week for three consecutive weeks to help the plant recover its growth. You can also provide the rose bush with timely water, keeping the soil moist, or set up a shade net for it to prevent the shoots from being sunburned by strong sunlight.
1. -- Spraying Pesticide --
If the tips of the rose bush shoots turn black, it might be due to pest damage during growth. In this case, you should cut off the blackened shoots and then spray the rose bush with omethoate solution to eliminate the pests. If you are concerned about the pesticide being harmful to humans, you can also use cigarette water to spray the rose bush.
2. -- Timely Watering --
If the tips of the rose bush shoots turn black, it might also be because the plant has absorbed too little water, leading to the shoots drying out due to lack of water. Therefore, it is necessary to provide timely water during the later care stage, preferably spraying the rose bush with water every three days, using uncontaminated natural water, such as lake water, for watering.
3. -- Supplementing Nutrients --
Rose bushes have a high demand for nutrients during the growth of new shoots. If the nutrients provided are insufficient, the plant may lack fertilizer and the shoots will turn black. Therefore, during the later care stage, it is necessary to provide the rose bush with a mixed fertilizer rich in nitrogen, phosphorus, and potassium elements to allow the plant to absorb balanced nutrition and grow healthily.
4. -- Reducing Sunlight --
The new shoots of the rose bush cannot grow in strong sunlight. If the shoots are exposed to direct sunlight for a long time, they will be sunburned and turn black. Therefore, during the later care stage, it is necessary to set up a shade net for the rose bush or move it to a well-lit but not direct sunlight environment to prevent the shoots from receiving direct sunlight.
