Frozen balls - it's a seedy business this 'ere wildlife gardening lark!

This is a good time of year to order wild flower and grass seed. It will be one less thing to worry about in spring when our time is more precious in the garden. Please remember how important it is not to alter wild areas by sowing or collecting seeds!

Ponds are increasingly likely to freeze over at this time of year. This causes two problems. One, animals are unable to drink and wash, and two, noxious gases from decomposition are locked in and essential gases locked out.

The solution is to float a piece of wood or a ball on the surface and remove it after freezing to leave some open water. Pour hot water over it if necessary. Avoid brightly-coloured or reflective materials as these might frighten wildlife. However, a ball isn't a good idea if you have pets or small children who might reach for it.
