Here's What's Growing This Weekend.
When the air warms and the lilacs bloom, Zone 6 and 7 gardeners can plant dahlia tubers outdoors. Set them 18 to 24 inches apart in soil mixed with some fertilizer.
Once your soil temperature reaches 50 degrees, you can start planting gladioli. I'd recommend planting these in sets and adding a new bunch every 10 days or so; that way, you'll have plenty for cutting once they bloom. Plant these 5 inches deep, 5 inches apart, again with plenty of fertilizer.
By now, your tulips have very likely gone by. If so, remove the tulip foliage—and if you hope to perennialize them, fertilize them now.
Move pots of tuberous begonias and other bulbs started indoors out to a sheltered spot to harden off. In a week or so you can move them to their permanent summer location.
As for pests, watch out for Japanese beetles! They can ruin the foliage of canna, dahlias, and other bulb flowers. If you find them, pick them off by hand.
