Who knows why the leaves of Chinese rose are eaten, but the worms can't find them? Insecticide. There's nothing I can do. What's the solution?

The reason is that the leaf shears cut off the leaves.

Leaf-cutting bees cut leaves not for foraging, but for nesting, storing "food" and laying eggs. I like to choose tender, thin, soft and fully unfolded middle and upper leaves as nesting materials. Because the leaf cutter bees cut the leaves repeatedly, they leave some regular nicks on the leaves.

Solution:

1, electrocute Feng Ye with a fly swatter.

It takes some time and patience. First of all, you need to know the visiting time of the leaf cutter bee. Leaf-cutting bees will be killed by flies when they cut leaves, and they can usually be removed in two or three days.

2, wind oil essence

Leaf-cutting bees hate the pungent smell, so they apply essential balm to the flowerpot rocks in advance. It should be noted that essential balm is volatile, and it will be replenished several times in the future until the leaf cutter forgets this place and will not come again.

3, sticky yellow board

Sticking a yellow board around the flowerpot can effectively drive away the leaf-cutting bees.

Step 4 change position

The leaf-cutting bee is very specific. It can move the flowerpot by one seat, and the leaf-cutting bee can't find it.

Matters needing attention in rose cultivation:

1, flowerpot:

In the choice of flowerpots, you can gradually choose the right flowerpots with the growth of plants. You can choose a flowerpot of about 15 cm at the seedling stage, and then use a bigger one for the later development of plants.

2. Soil:

Loose and breathable sandy soil is more suitable and needs to contain a lot of nutrients. Too sticky soil will hinder the growth of Chinese rose, so pay attention to avoid this kind of soil when choosing.

3. Lighting:

Rose is a plant that likes light and is not tolerant of shade. It takes a long time to be exposed to the sun to grow stronger.

4. Water:

In the early stage of germination, leaf growth and flowering, it is necessary to supply water in time, because roses will consume more nutrients during these periods. However, in winter, when the temperature is cold and the plants enter dormancy, watering should be reduced at this time.
