To grow in the selection of plants together in a pot for plants that have similar needs and growing conditions have no place. Garlic and salad are both planted in the fall or in the spring and both prefer sun to partial shade. However attracts salad moist, fertile soil as garlic. Harvest times vary, as well.
Garlic needs to grow a cold dormant period and good gardeners plant it in the fall in all except the coldest climates. Northern gardeners plant them in the spring. New shoots emerge in spring and mature in June or July, depending on the climate. Lettuce grows quickly in cool weather and is usually planted in spring or fall. It matures in 30 to 60 days and will be bitter when warm temperatures arrive. If you plant garlic and salad together, they will not ripen at the same time. The lettuce crop will be issued long before the garlic matures.
Lettuce grows high in rich, moist soil in nitrogen, while garlic prefer something dry conditions and less nitrogen. Both plants grow best in full sun, but tolerates partial shade. If you plant garlic in the fall, it may need a heavy straw mulch to protect it from winter damage. Sink the pot into the ground if possible to isolate it.
Lettuce plants produce lush foliage in a variety of colors, while producing high garlic plants tips of the leaves, like onions and chives. Planted together in a container, these two very different growing habits collide visually. Instead, try growing different types of salad with green herbs, such as dill or parsley.
Although garlic and lettuce can grow together in containers, other combinations probably make more sense. Grow garlic in the ground or in a pot by itself. Plant Salad with other cool season, leafy vegetables, such as arugula, broccoli or kale. Add pansies for a punch of color.
