Science-based companion planting

Much has been written about which plants work well together, and often the various human emotions, such as love and hate, accompany these descriptions. Extension agents, university professors, and other scientists had debunked most of the anecdotal benefits of traditional companion planting. 

But now there is new science on using various plants to:
- act as trap crops to lure pests away from crops,
- attract predatory insects that will reduce pest problems on crops,
- add diversity, which may confuse pest organisms.
- reduce weeds,
- increase pollinator populations,
- add nutrients, and more.

Jessica Walliser's new book, "Plant  Partners: Science-Based Companion Strategies for the Vegetable Garden" (published by Storey Publishing) is the winner of a 2021 The American Horticultural Society Book Award. Jessica is a rare two-time winner of this prestigious award and her book compiles this latest research on using plants to accomplish several benefits in vegetable gardens.

The lettuces

Lettuces: fast, easy-to-grow, cool-weather crops

I planted four types of lettuce in this bed: oakleaf,
black-seeded Simpson, drunken woman, & romaine.

Here in North Florida, we grow our cool-weather crops right through the winter. At the end of September, I planted four types of lettuces in a bed next to the house and also planted a curly parsley row there as well. The lettuces were oakleaf, black-seeded Simpson, drunken woman (which was new for us), and romaine. They all did very well, but the romaine gave us the longest and best harvest. I was remiss in not taking any good photos of this bed while it was in its peak. 

With leaf lettuces, you can harvest the outer leaves as needed or you can cut the plant off just above ground level with the hope that the plant would produce new leaves for a second or maybe a third harvest while the weather is still cool, This works best in Florida with varieties of lettuce that are more tolerant of warm weather or ones that are described as "slow-to-bolt."
