I have a smallish climbing rose on my balcony, along with some other plants
The rose is covered with tiny brown insects, so tiny at first I thought perhaps it was earth splashing up if rain had got in or something.
New to this planting thing, should I buy some insect killer or just try rinsing them off? Will they spread to the other plants? It's a tiny balcony so they all sit together. Thanks for any tips.
