As long as the area receives enough sun it should be just fine. My backyard property is much smaller than most, yet I still have a few spots where I can grow tomatoes.
Tomatoes grow really well in pots. Put the pot in full sun
Hi Louise. Pick a spot that gets full sun. Begin by tilling and loosening up the soil. Break up the big clumps and remove all weeds. The roots do well in loose soil. Scatter a bag of compost on the area and work it into the soil. Purchase your tomatoes. Dig holes and place a tomato in each hole. Approx 3 feet apart. Put a tomato cage right over each plant and feed your plants up thru the center of the cage as they grow. Water them at least every other day during the hot summer for 15 minutes. Pull any weeds that sprout up. Pick and enjoy. Good luck Louise.
Hi Louise: Along with the above suggestions, check the label on the plants and get the ones that are Determinate and not Indeterminate. The Determinate ones are the ones that grow short and bushy, just perfect for a patio planter. The Indeterminate are just crazy! They grow tall and leggy and need a lot of support posts. But, with good soil, fertilizer and watering, they will do just fine. Also, if you have a red pot, for some reason, red is good for tomatoes. Why? No idea:) Good luck
