Rosemary is suitable for growing in warm environment, but the environment is sultry and poorly ventilated, which will lead to slow growth. Rosemary growth rate is slow, if the temperature is high, ventilation is improper, growth is more inhibited. Yellow and dry leaves are just the beginning. If not ventilated in time, the whole plant will become weeds.
Rosemary likes sunshine. It needs to receive at least 6 hours of sunshine every day. If the sunlight is insufficient, the leaves produced by photosynthesis are less green, dark yellow, and the nutrients of the plants themselves are not enough. As time goes on, the leaves will gradually dry up, and it is easy to infect various diseases and insect pests.
The leaves of rosemary are narrow and luxuriant, so it's difficult to observe the insects on the leaves. In fact, some insects specially drill holes and attach to the back of the narrow leaves, which is difficult to observe. Therefore, in the maintenance, keep the environment clean, ventilate regularly, spray bactericide regularly, clean up the dead leaves on the surface of basin soil in time, and cut off the excessive and aged dead leaves.
