Hydrangea Scale protection
Lyndsay Griggs Posts: 23
I had one of my Hydrangea covered in hydrangea scale, which I found out what it was on here.
I am now wondering if there is anything I can do to protect my other hydrangeas from getting it, I keep checking them
Only a systemic insecticide would prevent them but that would also poison any visiting bees so not something I would do or recommend. Infestations only occur when adult scale is already present but goes unnoticed. When their eggs hatch young scale insect nymphs run all over the plant before settling. If you stay vigilent and rub-off any adult scales that you see it is unlikely you will get another infestation.
It's a sap-sucking insect Lyndsay, but they don't move once they have chosen a place to suck the sap. The young insects are highly mobile though and may arrive on birds feathers or cross from other hydrangea which are close by, especially if the leaves are touching.
Having to remove a very lovely hydrangea as is covered in hydrangea scale can i plant a new one in the same place or is the soil affected also?????
Scale insects don't infect the soil but I would mix some blood, fish and bone into the soil according to the directions on the pack to feed the soil before planting another one.
Hi thanks for the advise will do so.
