You can root fall tomatoes easily from existing tomato plants. The “old” plants continue to grow and produce in your garden while new seedlings take root. Then, by planting “cloned” seedlings, you can enjoy a whole new late tomato crop.

How long does it take for a tomato plant to grow?

Tomatoes love heat. They won’t really start to grow until both the soil and air temperatures remain warm. You can speed things up in the soil by covering the planting area with black or red plastic a couple of weeks before you intend to plant. Those extra degrees of soil warmth will translate into earlier tomatoes.

Why do you need to start tomato seeds from seed?

Starting tomatoes from seed allows you to grow the variety and quantity you desire. It also means you need to calculate the proper time for starting the plants. To do that, you need to know how long it will take your plants to reach the desired size, and the last expected frost date in your area.

With a hand shovel, make a hole large enough for the root ball of the transplant. Firm the soil around the roots and water the transplants. For a stronger, more vigorous plant, plant tomatoes so that some of the stem is below the soil line and new roots will emerge from the buried part of the stem.

Why are my tomato plants growing too close together?

Another cause may be planting tomatoes too closely together. Tomatoes are self-pollinating, meaning that each flower contains both the male (stamens) and female (pistils) parts. Wind typically pollinates tomatoes, but if plants are too close together, the wind can’t reach the flowers. What to do about it: Have your soil tested.

When to start tomato plants indoors or outside?
