4. Malformed or stunted leaves and flowers
What could have caused this is the presence of spider mites. They are tiny yellow, red or green spiders on the underside of leaves. They also suck juices from leaves. The application of Orthene or Isotox may help in treating this infestation.
5. Weak and mottled leaves with tiny white webs under them
This might be caused by aphids. They are small soft-bodied insects that usually brown, green or red. Often clustered under leaves and flower buds, they suck plant juices from tender buds. Malathion or diazinon spray may help roses to survive these bugs.
6. Flowers that don’t open or are deformed when they open.
Thrips could be the reason behind this deformation and unopened flowers. It is characterized with slender, brown-yellow bugs with fringed wings thriving in flower buds. They also suck juices from flower buds. One should cut and discard the infested flowers. Using Orthene and malathion may also treat this health problem of your roses.
This valuable information regarding the diseases your roses are prone to have will prove to be very helpful in making your rose gardening endeavor more rewarding.
