Still time to seed cilantro for a fall crop

Most everyone that has a vegetable garden is enjoying fresh tomatoes right now. Those of us who love fresh salsa, picante sauce and other Tex/Mex dishes that are flavored with cilantro are lamenting the fact that our garden cilantro has long since bolted and gone to seed.

Both temperature and day length influence flowering and seed setting with the longest vegetative period occurring when the plant is growing in the cooler temperatures and shorter days of spring and fall.

It is always aggravating to have someone tell you what you should have done, but I am going to go ahead and say it — you should have been harvesting the aromatic foliage of this popular plant when it was growing vigorously this spring and frozen it in resealable bags for use now in your Tex/Mex dishes. It doesn’t hold its flavor well when dried, so freezing is the best method.

All is not lost, as you can sow a fall crop of cilantro to have with your fall tomato crop. All you have to do is count back about 70 days from your typical first frost date, and sow cilantro seed on that date. For example, for north Mississippi our first frost is typically around Halloween, so I would sow my seed on Aug. 23.

Johnny’s Select Seeds indicate that cilantro will germinate in about seven-10 days and be ready for harvesting of leaves in 50-55 days. Only harvest about a third of the foliage at a time.

Seed begin to form in 90-105 days from seeding, at which point the foliage becomes a little “off” tasting and the life cycle of the plant will be ending. For a fall crop the plant may succumb to freezing temperatures before the seed are formed. Sow seed about a half-inch deep in well-drained soil.


Decisions have to made to remove plants from the garden. This time of year it is summer squash and Southern pea plants, which still are producing a little but are taking up a lot of room. Start new plants for later fresh supply or if your freezer or pantry isn’t stocked . Old squash plants can serve as a source of disease spores and is a particular problem if you are also trying to grow pumpkins.

Now is the time to start broccoli, cabbage, cauliflower, Brussels sprouts and other cole crops for fall gardening. These plants should be moved to the garden in mid-September. A new broccoli variety to try is Castle Dome, which has a shorter growing season than many varieties and makes a smooth head with small beads. Gardeners with sandy soils may get a response to added boron fertilizer when growing cole crops. It only takes a teaspoon per hundred feet of row and too much can kill plants.

Folks who just want a few cucumbers to make Fire and Ice salad during the hot days of September should locate seed of Patio Snacker cucumber. This variety was designed to be grown in containers and the plant seldom grows more than two feet. Cucumbers are full sized.


August is when the lawn should look its best. Any area not growing well should be investigated. This time of year is when it is easy to see that the tree has grown enough to prevent sunlight from reaching the grass at least half of the day.

Rains have slowed down enough that you can see if soil compaction is preventing root growth. Many thin, weak areas are treated with a fungicide when it is physical restrictions that are causing the grass to grow poorly.
