Hostas are thin
I LOVE Hostas and planted quite a few in our yard here in Massachusetts, where the soil in our yard is sandy. They have been coming up beautifully for the past seven or eight years. This spring, however, 5 of them in the same landscaped area only pushed up a few weak leaves. What happened? We've had plenty of rain and the area gets watered by our sprinklers every day.

I can think of two possible culprits for your failing hostas. Perhaps they accidentally got hit by overspray with a broadleaf weed killer that was applied to your turf. Or perhaps you've got voles. Voles generally travel in underground tunnels like moles, but they love to raid perennial beds and devour the crowns of perennials. Dig around a little where the hostas were and look for an open cavity where the crown used to be. If you do have voles, you can should be able to drive them off by lightly sprinkling bloodmeal onto the ground around your plants.
