|I have a gigantic malva alcea that is crowding out other plants. Is it too late to dig it up, divide it and transplant it somewhere else. The same applies to a sildacea. The sidalcea is looking kind of worn down this year after 3 years of vibrancy. Is it done? Should I throw it away?
How soon can I dig up my dafs and tulips, so I can plant more flowers where they were?
|Malva alcea is very deep rooted, and in my experience, would be difficult to transplant especially this late in the season. You might allow the malva to seed down, then select the best seedlings which are easy to transplant early in the spring, and discard the parent. If you are no longer satisfied with the sidalcea, then discard it. As with many perennials, this one seems to do better with a regular division program, usually every other year, best done in early spring. This allows time for the plant to become established before the heat of summer hits.
Daffodils and tulips must be allowed to ripen their foliage before digging. Ideally you would wait until the leaves are fully dried and brown.
