Excerpt from the "Three-Step Method of Rose Cultivation" series
At the end of yesterday's article, I left everyone with a question:
Why did the healthy rose suddenly droop its head?
I wonder if rose enthusiasts have encountered similar problems?
Rose stem sawflies cause significant damage to roses, far exceeding the damage caused by leaf sawflies and cutting sawflies.
Stem sawflies specifically target the tender branches of roses, laying their eggs inside the branches. After the eggs hatch, the larvae feed on the branch sap, causing the tender branches to lose water and droop.
Stem sawflies cause significant damage to roses, so what do stem sawflies look like?
Let's first get to know stem sawflies.
Stem sawflies are relatively thin and long, with a body length not exceeding 18 millimeters, a flat back edge on the mesothoracic plate, no narrow waist, cylindrical or somewhat flattened on the side, and a spur on the tibia of the front leg.
So how should we prevent and control stem sawflies?
Stem sawflies are so hateful, how should we prevent and control them? This should be the question everyone is most concerned about.
However, the control of rose stem sawflies is really quite troublesome. Because stem sawflies mainly lay eggs on tender branches to cause harm and then fly away after laying eggs.
Therefore, chemical control is not very effective. Unless you see stem sawflies, you can use radar spray to kill them.
But the probability of seeing them is still quite low, and our roses are often affected without our knowledge.
If your roses have been attacked by stem sawflies, you might as well try sticky insect boards. Buy some yellow sticky boards, which can have a certain effect, but they may also harm other flying insects.
If stem sawflies particularly favor your roses and sticky boards are not effective, you can only consider using a net to protect your roses.
Use a net with dense holes to cover your roses, and after coming several times without any gains, stem sawflies will naturally give up.
I hope these three methods of preventing and controlling stem sawflies are helpful to you.
So how should you deal with the tender rose branches that have been damaged by stem sawflies?
You must cut off the branches where stem sawflies have laid eggs promptly. If the branches have already withered, you must cut them until there are no longer any bored holes.
Otherwise, the larvae of stem sawflies will remain inside the branches and further harm the roses.
Speaking of problems encountered during rose cultivation, stem sawflies are just one of them. Because stem sawflies are a relatively common problem now, I have shared this information earlier.
Starting tomorrow, I will share continuously about common problems and coping methods in rose cultivation.
If you want your roses to be problem-free, have fewer problems, and be able to treat them promptly after problems arise, please continue to follow the subsequent articles.
