You can let tomato vines sprawl onto a bed of mulch but this looks messy and the fruit underneath the vine tends to get lost and left to rot. It's better to stake, trellis, or cage the plants.
There are different types of tomato cages. Some tall. Some short. Some round and some square.
If you are growing indeterminate tomatoes, use the largest, tallest tomato cages you can get to support them. You'll be glad you did later in the season when the plants have grown to gargantuan proportions.
You can either set a cage over each plant or you can plant 3-4 plants around each cage.
If you chose to do the latter, dig a hole and fill it with compost first. Set the cage over the hole and space the tomato plants about 2 feet apart around it. The compost will provide extra nutrients to the plants throughout the growing season.
Planting tomatoes in an upside down tomato planter is simple.
Pinch the lower leaves off the main stem and gently push the plant's root ball and main stem through the hole in the bottom of the planter.
You can plant 2 tomatoes if the planter is large enough.
Use newspaper to hold the seedling in place and keep your soil from escaping through the hole in the upside down tomato planter.
Fill the planter with a potting mix that contains water crystals. Hanging pots dry out quickly. Mix in some slow release tomato fertilizer. You don't want to have to take your upside down tomatoes down to do this later.
Hang the plant before you water it. Make sure the support is strong enough to hold the planter when the soil is wet. Check after watering to make sure the soil is at the correct level.
