Mid-fall is an unpredictable time of year. In cold regions quite severe frosts can suddenly strike, while in mild climates some plants are still growing and tender plants may go on flowering for a while. This is the time to listen to the weather forecast and to be on the alert, in particular, for frost warnings.
Mid-fall is the time to create and dig over any new flower beds for next spring, weeding them carefully. Collect seed from flowers, keeping it dry until sowing.
