Aerial or vertical planting can increase the amount of plants you can grow in your garden by saving ground space. It also lets you grow vegetables in places you wouldn't usually think to grow them, such as your deck or near a sun window. While it may seem like common sense, using an upside-down tomato planter requires a few considerations to make sure your plants are a success.
Determine how many tomato plants your upside-down tomato planter can hold. Count the number of slits or holes in the sides and bottom of the planter.
Purchase one tomato plant for each opening in your planter. Look for plants that are at least 6 inches tall, with several healthy leaves. Smaller plants might not thrive in this planter.
Locate the first hole in you planter. Guide your tomato plant through the inside of the planter, leaves first, and then gently guide the leaves though the hole. Working from the inside out causes the least amount of damage to the plant. Repeat this step until you have all your plants through the planter holes.
Fill the planter with moist potting soil. Adjust your plants as you add soil to make sure they are secure and well anchored. Tap down your planter gently to make sure soil gets in and around the root structure of each plant with no major gaps or air pockets.
Hang your planter in a location where it will get at least eight hours of bright sunlight each day. Water your planter daily, especially in the hottest months. Because the planter is small with less soil than you would traditionally use to plant this many tomato plants, it will dry out quickly and may need twice daily watering.
