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.
Fall is the prime time to grow broccoli and cauliflower in Southland gardens. Both love the bright days and cool nights of our autumn growing season. Gardeners new to our area often try to grow these vegetables in the spring--the traditional growing time in most of the rest of the country. This is a mistake in all but the coastal areas of Southern California, as spring-grown broccoli and cauliflower often do not have time to form proper heads before bolting to seed. Beginning this month, transplants for broccoli and cauliflower start showing up at local nurseries.
