No problem but you will only get green leaves less flowers. A handful of bonemeal in each hole and they should bloom next year.

2 weeks ago I found a bag of mixed daffodils in the garage that hadn't been planted in fall. Some had green growing. Potted them up with some Bulbtone (can't hurt as far as I know) and greenery still growing with some new shoots emerging around all 4 pots. Will keep them going until fall, trim spent greenery and then plant in ground. Shame to waste them and they seem hardy so worth a try. Besides, now I'll see what color/form they are and can put them where I like them best among other bulbs already in beds.

Besides crocus there isn't much up except a few yellow daffs. Plenty of green and just waiting on the blooms through early summer.
