None of the spring bulbs I've bought give me any idea when it is safe to put them in the ground.
I'm in north zone 5 on a hillside that is a bit colder than the rest of the county. We still have one last patch of ice in the yard and my compost heap is still frozen but my bulbs are growing like gangbusters.
The stuff I bought includes:
- Dahlias (regular and the spiny type). I potted up last year's which I stored in peat in the basement to see if I could give them a head start (and figure out if they are still alive.) I am wondering if I should pot up the new ones to give them a head start, too. I was told I can't plant these until no frost and last year mine seemed to take forever to grow from roots and they flowered later than everyone else's I saw on my walks, though they did eventually have pretty flowers. Should I pot the new ones to get a head start or just wait until it's warmer?
- Lily of the Valley - I've got a lot of woodsy shade that won't grow much under some oaks. I read online that they probably won't flower this year.
- Balloon flower.
- Clematis (well, there's a bit of help with them. The packages says "when the ground temperature is 50 degrees". Does that mean they can withstand a night frost? The ones I got are teensy and I stuck these in potting soil with a stick to climb as they were already growing in the bag. From reading about them online, it sounds like maybe I should grow them in big containers on my deck this summer and plant them in September. I'd like to have them grow on the trellis surrounding our deck where we had a really nice show of Morning glories last year. It isn't full sun by any stretch of the imagination, but the morning glories didn't seem to mind, so I'm hoping they clematis won't either.
Also, what about planting dianthus? I found some for sale next to the pansies and wondered if this means I can put them in the ground now.
I learned an amazing amount about gardening here last year and am really excited about what I'm going to be able to do this year.
