The buxus moth has come to Europe recent years and has arrived in central France, people are desperately using chemicals to kill off the caterpillars. Huge bushes i've seen completely devoured. I'd kept mine low as a wind break around my veggie garden. Internet said the leaves would come back, but they haven't so far, any way, they'll die in next years cycle. So i decided to make the hedge a rosemary hedge, which i use in massage oil and to make a hydrosol for hair and help with concentration. Had some two year old cuttings to start the replacement.
Lavender is great as well, but i haven't managed to propagate it by layering or cuttings so far. Bought some seeds that grew plants, hope to get viable seeds from those. Lavender hedges grow quite wide, they don't take kindly to trimming like rosemary.
Hester. What new plague comes will come. Nothing i can do about it. I had never heard of the rosemary beetle until you mentioned it. I have about 250 different plant species in my garden and that provides for a lot of different insects, which provides for a lot of birds, which do their bit in pest control. I’ve read it’s good to have clusters of plants. Easier to find for insects when they flower. As well i find blocks easier to maintain and harvest. On top of that they seem to thrive if i cluster them, while solo they have to put up a fight to survive. I prefer the calmer look of it as well. Others tend to think my garden is chaotic any way. I think they wouldn’t understand if i make it even more so.
If my 3 meter hedgerow of rosemary is going to fall prey to beetles so be it. I’m hoping for a 30 meter one in the coming years elsewhere. Guess i’ll break it up now.
