Week Four: Acquainting ourselves with the solanaceae family, and with the three-striped potato beetle

Cool weather and a good heavy rain offered sweet relief to our brassicas and good conditions for transplanting starts from the solanaceae family. Solanaceae, also called nightshades, are characterized by their flowering plants and include the many varieties of potatoes, tomatoes, tomatillos, eggplants, and peppers.

The transplant was quite similar to the transplanting of the brassica family. Tomatoes require slightly more attention as they tends to grow into heavily fruit-bearing and therefore top-heavy plants. Our tomato transplants ranged from about six to twelve inches and had a soft, white fuzz quality to the bottom half of the stalk. This fuzz is the beginning of what will become a strong root system, and therefore wants to be submerged fully underground. Tomatoes want to be planted in a hole that is one-half as deep as their overall height (at the time of transplant). This requires the careful removal of low-growing branches. Finally, removing all flowers and suckers will encourage the plant to allocated its energy to the establishment of a strong and developed root system. This is crucial to the health of the plant.

Eggplant and peppers need not be buried as deep as the tomato. Just slightly above the existing soil line is fine. Pinching off any premature flowering will improve the health of the plant. Below is Alex choosing what to plant from a variety of peppers!


As for the tomatillo, the transplant is just like that of the eggplant and the pepper. The plant itself though will grow to be quite large and so we’ve dedicated one of our communal beds to the tomatillo crop. To no surprise, the three-striped potato beetle arrived within two weeks of planting.


Also called the three-lined potato beetle, this pest can live off of the leaves of any member of the solanaceae family but has a preference for the tomatillo. We had the opportunity to observe about twenty beetles spread across our five tomatillo plants. It was mid-morning, they were mating, and the backsides of the plant’s leaves were marked with the yellow-orange eggs of the next generation. These pests cannot merely be pulled off of the plant. They must be removed from the garden – either in a tightly sealed container or in a cup of soapy water. The eggs need only to be wiped off of the leaves for the newborns require immediate sustenance and will not survive if born away from their food source.
