Some of my Hibiscus were severily attack by aphids, mealybugs and thrips, in result the leaves and flowers are small and curled. I'm still treating the plants for the pests,but is there a way to get them back on track?How can I get an Hibiscus to grow strong and bloom again?
Ladybugs will take care of the aphids, mealybugs and thrips. Hard insecticides are bad for the plants. Spring is the time to fertilize, make sure the middle number is high when you choose your fertilizer. Another thing to remember is hibiscus like the sun but also like water so you have to water your hibiscus often.How can I get an Hibiscus to grow strong and bloom again?
Storyofstuff is right, hibiscus are know for problems, but the flowers are worth it. Cut it back..toss the clippings...give a lil fertilizer and it will pop back pretty as ever. If these hibiscus are close together might as well cut um all back and start fresh .
those should have been cut back to the ground every year, they will take care of them selfs, if you had a pest problem you can just hope you dont have one this year.
If the hibiscus is a woody type, it is probably a lost cause. Aphids can readily transmit viruses to plants. Once a plant gets a virus, there is no way to save it. The curled leaves and blooms are an indication of a virus. Your best bet is to dig it up and burn it. Do not plant another in the same spot. The virus will have gotten into the soil and will be taken up in the roots of any plant placed there. These links will explain.
