How late can you plant perennials, shrubs, etc?
I have read a few threads on this subject and I'm still uncertain of how late I can plant. Quite a few people said fall is a good time to plant because it gives the plant time to develop strong roots before the heat comes on.
When you get a chance please answer these questions:
1. How late can I plant perennials?
2. If the cut-off date is fall, exactly what month is the lastest I can plant?
3. Can I plant Juniper trees in fall? (up to what month)
4. As I understand some decidious trees should not be planted in fall b/c they are marginally hardy in zone 5, such as an evergreen Magnolia (Brakens Beauty). Can a sweetbay Magnolia be planted in fall?
5. Up to what month can ornamental grasses and shrub roses (i.e knockout) be planted?
5a.Why is a plant at risk if planted in fall? or right near the time ground freezes? Does the ground freeze all the way down to where the roots are and then kill the plant?
6. Last question what does bareroot mean, how is that different than b&b.
Thank you so much for your anticipated response to these many questions.
