How to Grow Italian Heirloom Tomatoes
HOW TO GROW ITALIAN HEIRLOOM TOMATOES
PLANTING ITALIAN HEIRLOOM TOMATOES
Plant your Italian heirloom tomato seeds in organic soil. This should consist of compost which enough fertilizer and moisture.
Plant early in the spring, as soon as all danger of frost has passed. You can also start seeds indoors. If you’re not comfortable growing tomatoes from seeds, you can purchase small plants from your local nursery.
Seedlings will sprout within 6-8 weeks and will need to be hardened before transplanted outdoors.
Once transplanted, thin the seedlings and pinch off the top to create stronger plants.
Sow each seed at about 1/4″ inch deep and space each row 4′ apart.
Space each plant 36″ apart.
Transplant your seedlings in an area with full sun, and be mindful that they’ll need an average temperature of 65F (18C) to thrive.
Once the plants become sturdy enough, stake them.
Tomato plants also need a lot of water so be sure to mulch around the plants for consistent moisture and water regularly.
HARVESTING ITALIAN HEIRLOOM TOMATOES:
You can start harvesting your tomatoes the second they get ripe. This will usually be 65-80 days after planting.
The more often you harvest, the more tomatoes you’ll have growing in!
You can also harvest green tomatoes, especially at the end of the growing season as they’ll keep for about 4 weeks, after which they will ripen on their own.
