Starting Plants From Seed on a Windowsill

A tray, a bag of compost and a bright window are all it takes to grow your own seedlings. Most of it comes down to paying attention: a plant tells you what it needs well before it is in trouble.

Feed in the growing season

From spring to late summer, when a plant is putting out new leaves, a weak liquid feed once a month is plenty. In winter most plants rest, and feeding them then does more harm than good.

Clean the leaves

Dust blocks light. Wipe large leaves with a damp cloth every month or so; rinse small-leaved plants under a lukewarm shower. They will look better and grow better.
