I am having trouble getting cilantro seeds to germinate outside during July and August and also inside during those months. Right now I have some seeds in a plastic bag with moist potting soil and they haven’t germinated after 3 weeks. Any tips?

There could be a few reasons why you aren't having much luck. It's possible you are planting the seed too deeply. Seeds should be planted 1/4 to 1/2 inches deep. You may also want to do a germination test to see if your seed is viable. Get a paper towel wet and place 10 seeds on the towel and fold it over the seed. Then place the paper towel and seeds in a plastic bag and seal it. Watch the bag to see how man seeds germinate. Cilantro also tends to like cooler temperatures and will germinate best when soil temperatures are between 55 and 68 F.
