m0useanswered grow question 3 years ago if the spiders are as small or smaller then the period in this sentence you have issues.
If not then they are a most likely predators.
Familiarize yourself with spider mites to rules them out, that's the dangerous one. They feed on plants and kill them.
Any other spiders in your garden eat other things. mainly bugs.

If they are not mites and are garden spiders, can brush them off and hopefully they will go away, a nest may have hatched around your plant and that's why they are all on it right now. When I grow outdoors I see little nests in a leaf folds, I just pluck them off as I do not like an abundance of spiders. I do get the little black and yellow jumping spiders and they are ok in my books. no webs or messy bits.
