How to Harvest Annual and Perennial Herbs
So you’ve been growing herbs and now it’s time for a big, end-of-summer harvest. You watched our new video where Tricia shows you how to harvest and preserve herbs—and she says that you should use different techniques for annual and perennial herbs.
Wait a minute—which herbs are annuals and which are perennials? They all grow in the summer.
We’ll give you a quick guide to which herbs are annual and which are perennial.
Some herbs are easy to figure out. An evergreen like rosemary, that lives on through winter snows and increases in size over the years is a perennial.
Cilantro has delicate leaves and that’s a tip-off that it’s an annual.
Within perennials there are two kinds—tough-customer hardy perennials like lavender that make it through a USDA zone 7 winter, and the tender perennials that make it through a “rough” Santa Barbara winter (they’ll only be perennial for you in zones 9 - 11).
By the way, the USDA recently relabeled many of the zones, so your own USDA zone might have a new number. Find out your current number here.
The odds are that if you have herbs in your garden you have both annuals and perennials. Coming up are lists of both kinds of herbs, along with the techniques for harvesting and preserving them.
Harvesting annual herbs
Do you grow any of these popular, annual herbs?
Biennials that can be grown and harvested as annuals
Harvest time for annuals
Throughout the summer you can typically harvest quite a bit of an annual herb plant. A good rule of thumb is to leave four to six inches of plant for later growth.
Preserving annual herbs
Freezing retains the best flavor for: parsley, cilantro, chervil, sweet cicely, chives, tarragon, dill, and fennel.
Harvesting perennial herbs
Are these perennial herbs in your garden?
Harvest time for perennial herbs
Perennial herbs should usually be harvested throughout the summer until two months before the first frost of fall. Harvest about one third of the current season’s growth, for some it is just the growing tips. You don’t want to harvest them too late into the season because the plant will produce tender growth that won’t have time to harden off before the frost comes.
Preserving perennial herbs
Drying retains the best flavor for: mint, thyme, lavender, oregano, marjoram, sage, rosemary, savory, lovage, lemon verbena, and lemon balm. Tricia uses one of our dehydrators, and also shows you how to bundle and hang herbs to dry.
Process your herb harvest quickly
Snip the herbs you need quickly, neatly, and evenly with our herb scissors. The unusual blade design features a set of five, sharp 3” stainless steel blades that allow you to cut, chop or mince herbs directly into a pan or over a plate for garnishing. The large plastic handles have a soft silicone lining for a comfortable grip. At a generous 7 1/2” long overall, the scissors are dishwasher safe and come with a blade cleaner/storage case.
