Too late to transplant?
I have some lavender, asters, coreopsis, Russian sage and Bo-Bo hydrangeas that I want to move. Is it too late to attempt that now or should I wait till early spring? Thanks, Mary Parker
Here is a good resource on transplanting perennials. https://extension.usu.edu/files/publications/factsheet/pub__4864455.htm
You are cutting it a little close. The average first hard freeze in Kentucky is early November. http://www.weather.gov/lmk/lexington_freeze_infoTypically you want a good three to four weeks before that first hard freeze. Remember, average does not mean that's when the first hard freeze will happen; sometimes we get them sooner, sometimes later. If you decide to risk it, I would pay particular attention to some of the mulching instructions in the linked publication. Mulching can help if we have dry weeks ahead (most people don't think about the fall and early winter being dry). Mulch more importantly helps provide stable and warmer temperatures.

Fall is a good time for transplanting typically. But a few weeks earlier would have been safest for the plants.
