Leave seedheads on for the birds
Allowing seedheads to remain on some perennials in borders will boost birds’ food stores. The strong upright stems of echinacea, monarda, rudbeckia and agastache look great over winter, and are a good source of seeds for tits and finches.
The taller teasels and grasses may need support, so use a few bare twigs strategically pressed into the ground to keep them aloft. Leave them until next spring and cut them back when new shoots appear at the base.
