Yeah it's pansy time here in WI! So I bought some and potted them up on Sunday. Now I would like to actually keep them healthy and happy and hopefully have them fill out the pot! So I have dutifully watered and am now wondering when/if I should fertlize? All have open blooms and one pot has some chives in it as well. I do have a fish/seaweed fertilizer that I could use. When should I use it and are there signs that a pot needs fertilizer?
