Grow tomatoes in a hanging pot for a productive patio plant. Smaller determinate varieties are best for hanging baskets and pots. Many nurseries market tomatoes specifically for this use, so consult a local nursery or your county extension agent for varieties that grow well in your area. Hang the pot in a sunny window or on the patio where it will receive at least eight hours of sun daily. Protect the tomatoes from extreme temperatures by bringing the pot indoors when temperatures climb above 90 degrees F or below 50 degrees F.
Choose a hanging basket or pot at least 12 inches in diameter with good drainage.
Place a piece of window screen over the bottom of the pot to keep the soil from washing away.
Fill the pot to within 3/4 inch of the top with potting soil. Mix in a slow release tomato fertilizer.
Form a small hole for the tomato plant. Place the plant into the hole, burying it a little deeper than it was originally planted. Press the soil in around the plant.
Water the plant to moisten the soil thoroughly. Continue watering every day or two as needed to keep the soil moist. Water deeply each time until water runs out the drain hole.
Hang the pot in a sunny location out of the wind. Turn the plant every other day to encourage even growth.
Use a water-soluble tomato fertilizer when the tomatoes begin to form. Continue fertilizing every two to three weeks while the tomatoes are growing.
