Harvesting Herbs

Picking Fresh

Do remember that herbs should be harvested when the oils responsible for flavour and aroma are at their peak. Begin harvesting the herb when the plant has enough foliage to maintain growth. Try not to pick more than a third so the plant becomes too bare and gives the plant time to recover. Harvest early in the morning, after the dew dries, but before the heat of the day.

Dried Herbs

Freezing Herbs

Overwintering Herbs

You could opt to place them in sheltered areas of the garden like along a wall out the way or place them in a cold frame if you have one. You can even relocate your herbs into an open-front shed.
