Absolute novice - help! Reviving front garden
im absolutely new to gardening and hope I can draw upon your knowledge to help with my front hedge problem. 4 buxus balls were killed as a matter of days, having looked it up it appears that it was due to scale insect, when I was digging plants out I saw lots of caterpillars too and those seem to be box plant ones. Now I want to order new box plants and lavender to plant in their place and dont know if I need to replace ground, pour insecticide all over it or leave it for now and re plant in a month? I don't want to spend money for the plants to be killed again in a few days... :-( also, is it good time to plant now?
many thanks!!! Your help is really appreciated xx
