Living things respond to their environment. Response to stimuli is an important characteristic of life. Anything that causes a living organism to react is called a stimulus (plural is stimuli) Stimuli can be external or internal. For instance, if you feel like going to the bathroom, it is an internal stimulus that is controlled by the brain.
Planting leafy green vegetables is easy, but itâs all in the timing. Knowing when to plant greens (such as spinach, kale, and lettuce) depends on your climate and if the leaf vegetables are heat- or cold-tolerant. Greens grow year-round in areas with mild summers and winters, such as the West Coast. For most other areas, spring and fall are the best times to grow greens.
Chinese greens are next on the list of crops you can plant in August. These are also technically part of the brassica family. But again they deserve there own spot on the list. Chinese greens like, pac choy and tatsoi are very hardy and grow super well in the fall.
