|Last spring I had planted two shasta daisies, but it is mid May and still haven't seen any sign of life yet. How long should I wait before I know that they are not coming back?
|Shasta daisies are perennial plants. The tops of the plants will die down in the winter, but new sprouts will appear in spring and the plants will bloom from mid-summer through fall. I suspect you'll begin to see new sprouts within the next too weeks. If not, the roots may have drowned over the winter months. If poorly draining soil is a problem in your garden, you might try planting them in raised beds (which not only drain well but warm up faster in the spring, so you'll see them sprout several weeks earlier!) Shasta daisies perform best in full sunshine, in average but well-draining soil.
