Carrots don't require much space. It all depends on how big the roots are at harvest time. If you're growing baby carrots, spacing them between 3/4 of an inch and 2 inches. If you want bigger carrots, thinning to a final spacing of 2 inches-4 inches is about right.

Carrots need a good moisture supply to become well established and to produce good root development. Carrots need at least 1 inch of water each week during the growing season. Remember to soak the soil thoroughly when watering.

Carrots are very easy to harvest. Simply pull up the plant by the tops (the green leafy part). You can basically harvest them any time, depending on the size you want. For baby carrots, harvest them at 4 to 5 inches. For bigger carrots, harvest them at 3/4 to 1 1/2 inches.

Peas

Peas need nutrient rich soil produce a good crop. Peas planted in early spring do well in raised beds that have good drainage. They can be started as soon as the soil can be worked.

Peas need to be planted 1 to 1 1/2 inches apart in all directions. The rows should be 12 to 18 inches apart. If you are planting a large bed of peas, you can plant them in a zig-zag pattern with 12 to 18 inches between the plants.

Peas need lots of even moisture throughout the growing season. They like soil with good drainage and if they stay too wet, they will get root rot.

You know your peas are ready to harvest when their pods are plump but not bursting. Harvest them every 2-4 days to encourage them to keep growing.

Green Beans

Green beans are easy to grow, and will thrive in almost any soil. They need to have good drainage though, or the seeds will rot. To prepare the soil, break up large clods of dirt and rake the area smooth.

Plant your beans 1 to 1 1/2 inches deep, and 2 inches apart within rows. Space the rows about 24 to 36 inches. If you want lots of beans, plant beans every two weeks, until a good month and a half before first expected frost date.

Peas need lots of moisture during germination. Water them deeply once a week, making sure the soil drains well. Once your peas have started to sprout, you don't need to irrigate them as much.

Fresh beans are usually ready for harvest about 8 to 10 days after flowering. They will be pencil thin, and the beans will be bright green. The bean pods will snap easily when bent. Pinch or cut the beans off rather than pulling them.

Potatoes

Potatoes need well-drained soil. It's a good idea to mix compost into your bed to make sure there are plenty of nutrients in the soil.

Plant your potato seeds in early spring, about 3 weeks before the last frost. Space your potatoes between 6 and 12 inches apart, in shallow holes (about 3 inches deep). Make the rows between 30 and 36 inches.

Keep your potatoes evenly moist and water them deeply during dry spells. If you plant your potatoes in a hill, they will dry out quicker so watch the soil moisture carefully.

You'll know your potatoes are ready to harvest when their leaves die back. Some people prefer ?new potatoes.? These are immature potatoes that are picked several months after planting, but before the potato plants reach maturity. You can find these new potatoes when the potato plants blossom.
