Episode Details

Are you trying to grow a salsa garden? It's great that most of the ingredients for salsa ripen at about the same time in the backyard garden. The main salsa ingredients - tomatoes, peppers, onions, and garlic - are ready this time of year. And if you wait until September or October to make the salsa, there might be some limes ready from a backyard lime tree in citrus growing regions. But there is one ingredient that throws off that salsa recipe timing: cilantro. Cilantro is easy to grow in hot climates in fall, winter, and early spring. But in hot summers? You can forget about it being ready when the rest of your salsa ingredients are all growing fine. Because of the rising frequency of extended, triple digit summer temperatures (“heat dome” seems to be the 2024 phrase that pays), cilantro is going to turn bitter and send up flower stalks (which, by the way, the beneficial insects love).

You could buy cilantro at the store or farmer’s market. But the aroma and tangy taste of fresh, homegrown, just-picked cilantro can’t be beat.

Before we delve into the solution for getting fresh homegrown cilantro in the summer, here’s what you may have missed in last Friday’s Garden Basics with Farmer Fred Podcast, #348:

Right now - mid-summer - is peach and plum harvest time for most of us. Phil Pursel of Dave Wilson Nursery talks about choosing the tastiest peach and plum tree varieties, along with care tips, including watering and fertilization. Phil points out the difference between freestone and cling peaches, the importance of chill hours for peach trees, and the major insect pests of peach trees. Phil’s favorite peach: the Red Baron. Fred’s favorite: a dwarf variety, the Garden Gold peach. Phil’s favorite plum: the Emerald Beaut. Fred’s tastiest favorite plum: The weeping Santa Rosa plum.

We’ve talked in the past about ways to improve clay soil; but what about sandy soil? Maser Gardener Gail Pothour offers tips for a listener in Michigan on what to add to that sandy soil to help it retain nutrients and water. And it turns out, Gail is also knowledgeable about how parts of Michigan got its sandy soil to begin with!

The episode concludes with our America’s Favorite Retired College Horticulture Professor, Debbie Flower, dissecting a listener’s plan for adding sticks to the bottom of a new raised bed. Even though it’s counterintuitive, that can actually slow down the flow of water through the bed, leading to possible wet soil problems for the plant roots. Unlike what water does above ground (fall through the air, downward). Underground, water must travel along soil particles, not air particles - to head downward. Thus, the importance of using a uniform soil type throughout the container or raised bed.

How To Grow Cilantro in a Hot Summer Climate

There is a solution for cilantro lovers who garden in a hot climate, according to Renee Shepherd, owner of Renee’s Garden seed catalog: Grow cilantro as a microgreen. “Pick it when it's very young, just a few inches tall,” advises Shepherd, based in Santa Cruz County, CA. “The hotter the weather, the younger you pick it. I have seen it growing that way in the Napa Valley. I work with a grower there who besides growing the cilantro seed for us, grows very fancy greens for upscale restaurants in San Francisco. And it's very hot in Napa, just as hot as where you are. He's successful growing cilantro as a microgreen. He uses row covers for protection and grows it in an area that gets afternoon shade through the summer.”
