by Ray AllenWait! Don't put those garden tools away. June is a great planting month in almost the entire country. As for wildflower seeds, it's fine; you'll just have to water more. And as for perennials and bulbs, just use common sense. Bulbs like glads, dahlias, cannas, and callas can be planted in the ground or in patio pots all month. Just be sure you keep them watered while they grow. For late planting of perennials, start with the ones that bloom in summer or fall. If you plant spring bloomers (say, bleeding hearts), they'll be fine, but you won't see bloom until next spring. But go ahead and fill in those spaces. It's not too late.
