Weed seedlings Hoe or winkle out freshly germinated seedlings of weeds that are hard to get rid of once mature, such as Galium aparine (aka goosegrass), alkanet, dandelion and dock. Reuse compost To save time and effort later, tip out the compost from last year's summer containers and spread it around the garden. Wash and two-thirds refill the pots with fresh compost ready for replanting. Clean up On a fine day tidy up and sweep out your shed and/or greenhouse. Wash and prepare seed trays, root-trainers et cetera.
