Chives grow quickly in spring and summer. Cut as you need them for use, trimming right down to the base. Keep four or five pots at the ready, so you always have some at different stages to harvest.
When cutting parsley, always remove the whole leaf, together with the leaf stalk, nipping it back to where it joins the clump. Avoid the oldest leaves as these tend to be tough.
Cutting rosemary for culinary use will prevent the plant from becoming woody. Use secateurs to trim 10cm - 15cm from each shoot, as required. Avoid cutting back into woody, leafless branches. Hang up bunches of rosemary to air dry, ready to use in winter.
When harvesting basil, nip out with scissors or between finger and thumb, the tips of the plants back to just above a pair of leaves. New growth will emerge at this point. Don't nip just below the leaf, leaving a short stem, as this will simply wither.
