Multiplication - it's not maths, honest

February is a good time to divide wildlife-friendly perennials, such as golden rod (Solidago canadensis), knapweeds (Centaurea scabiosa), ice plant (Sedum spectabile and other Sedums), yarrow (Achillea Spp.), lily of the valley (Convallaria majalis) and michaelmas daisy (Aster novi-belgii). These plants will provide nectar and pollen for bees, butterflies, hoverflies and many other insects. Michaelmas daisies should be replanted in a new spot every 2 to 3 years as they deplete nutrients quickly.

Watch out for frog and toad spawn. Although both are translucent jelly with dark spots, they are easy to distinguish. Frog spawn is laid in a mass of spheres and toad spawn is laid in strips. Frog spawn is normally laid on the surface. It sometimes dries out in garden ponds as the water level can drop quickly, leaving it stranded on top of pond plants. You could always rescue it. Toads lay their spawn more deeply and tangle it around aquatic plants.
