How to help sunflower?
Hi all.
Slugs have been eating the stem of my sunflower pretty bad so i used some wool as a protective measure to cover the base of the stem a few nights ago.
Today, one of the sunflowers does not look so great and i’m wondering if this could be doing more harm than good. Or could this be pointing to another issue?
They get watered every evening so nothing has changed in that area.
Thanks
