Hello Charles and all
The last three raised beds I put in last year (wooden sides, 6″ deep) were placed over grass and existing flower borders. I cleared what I thought were most of the perennial flowers and some shrubs but now ornamental alliums are springing up in two of the beds and will require removal.
My question is this. If I just remove the top growth will they eventually just give up coming up? I dug out as many as I could find before placing the new beds but you know what bulbs are like. I do not want to try digging them out again now.
Also, on some old raised beds down by the Apple tree I noticed last year that bindweed was making a comeback. I have open land at the back of my property and it is creeping in from there. About ten years ago I put glyphosate on it (the only chemical I have ever used and only for this purpose) which halted it for this long. Haven’t used glyphosate since and don’t want to again. I noticed it was in my spring small shrub and bulb boarder and creeping into these raised beds too. I trowelled it out and disposed of it but it was rife at that end of the garden. As it is coming from ‘the other side of the fence’ am I fighting a losing battle?
Cheers all
Eliza
