Picking herbs is good for them

This is great weather for tomatoes, sunny and hot just how they like it. We should get a bumper crop of very red tomatoes, packed with flavor. But herbs are taking the heat. Watering is very important now. Picking herbs and greens helps prevent them from forming seeds. The best way to pick parsley, and many herbs and leafy vegetables, is to snip the whole leaf and stem from the stock. Sometimes you can twist them off, when you pick parsley and Swiss chard.
Basil's a little different. You should cut the stock or branch, just above leaves, well below the leaves you want to harvest. Picking in late morning is the best time of day, especially for greens and herbs.
Pick leaves often to prevent the plants from going to seed. Because once they go to seed, many of the plants lose their herbiness flavor.
For Rosemary and sage, cut 5 inch branches and hang to air dry or chop and freeze in herb ice cubes or clumps in a freezer bag.
