Autumn-planted seedlings of hardy spring annuals not yet in flower can be supplemented with mature bloomers for instant colour.
Young seedlings will benefit from some liquid plant food. And although snails tend to hibernate over winter, slugs are still active so baits are still advised.
Plant the last of the fruiting trees in well prepared, free-draining sites. Where space is limited, plant two trees in one hole; alternatively purchase a double or triple grafted plant. Or you can espalier along a wall or against a fence as a free standing hedge.
Rake leaves from lawns onto garden beds but not too thickly, or supplementary watering may not reach the plant roots.
