Decide how big of a garden you want. If you're not sure, you can always start small. While you think about it, plan around an area that gets at least six hours of sunlight. More would be better.
Now you can choose what you want to grow. Keep in mind what grows best in your area and the space you have allocated. If you plant seeds, the packet will have clear directions. Just remember that seeds take longer than container plants, which you can put in the ground during the spring after the last frost.
With vegetables, timing is everything. Broccoli, carrots, lettuce, peas, and spinach like cool weather. So you can plant them one month before the last expected frost. After the last frost, plant your warm-weather vegetables: corn, tomatoes, cucumbers, and peppers.
At the seedling stage, your plants just need to be kept moist. Later on, make watering and feeding a regular routine. Aim for the base of the plant. For excellent results, try Miracle-Gro® Organic Choice® All-Purpose Organic Plant Food, followed by a healthy dose of water. Another way to go is to feed and water at the same time with products such as Miracle-Gro® LiquaFeed®.
Weeds compete with your vegetables. They steal nutrients, water, and sunlight, so you want to keep them out. A two-inch layer of mulch around your plants will help discourage weeds. Grass clippings work, too. They also provide nitrogen as they break down. Once your plants are mature, put a layer of pre-emergent around your garden bed.
