Planting coriander and what to do in your garden this week:
BOTH the aromatic leaves and stems of coriander can be used to add flavour and fragrance to curries, salsas and other spicy dishes.
Sow seeds in succession from March until August and you should have leaves from June until October. Seeds can be sown 2.5cm deep and 5cm apart, directly into beds of rich, well-drained soil in light shade to prevent bolting, keep well-weeded and well-watered and let some plants develop seed to save and use next year.
Cut the flowerheads when the seeds are brown, cover with a paper bag and hang up to dry in a warm place. Good varieties for leaves include 'Leisure' and 'Calypso'
Jobs for this week:
Reduce the length of wisteria tendrils by half.
Water dahlias regularly and feed fortnightly, paying particular attention to young plants which are slow to grow.
Go on slug and snail patrol in your garden, particularly after a heavy downpour, and pick off all those you see.
Peg down runners on strawberry plants that you want to propagate.
Feed late-flowering border perennials.
Collect and sow or store ripe seeds before they fall.
Plant autumn-flowering bulbs such as amaryllis, nerines and autumn crocuses.
Summer-prune side-shoots of wall-trained plums and cherries, with the exception of Morello.
Where roots are exposed due to watering, apply a top-dressing of John Innes No 3 compost to tomatoes.
Buy winter varieties of spinach, which can be sown in August and September to crop between October and April.
Top up ponds on a regular basis because water can evaporate quickly during hot spells.
Thin oxygenating plants in the pond before they take over completely. Pull them out with a rake and leave them to dry out, to allow any wildlife hiding inside to escape.
Sow coriander seeds over summer
