Why Your Tomatoes Aren't Producing (And How to Fix It)

I can't tell you how many folks come up to me at the farmers market frustrated about tomato plants that look healthy but just won't produce.

Green leaves. Good height. Plenty of flowers. But no tomatoes.

Usually, it's not one big problem. It's three or four little things stacking up — too much water, not enough calcium, poor airflow, or planting too shallow.

Now here's the good news: those are all fixable.

1. You're Watering Too Much (or Too Inconsistently)

Tomatoes don't like wet feet. They like deep, consistent moisture — not daily surface watering that keeps the top inch wet while the roots stay dry.

What I recommend: water deeply two or three times a week, letting the soil dry slightly between waterings. The goal is to encourage roots to grow down, not stay shallow.

Inconsistent watering — soaking one day, bone dry the next — is also the number one cause of blossom end rot and cracked fruit. A good watering ring around the base of the plant, like the Tomato Crater®, directs water straight to the root zone where it belongs.

2. Not Enough Calcium

Calcium deficiency is sneaky. The plant looks fine on the outside, but inside it's struggling to move nutrients from the roots to the fruit.

Signs to watch for: blossom end rot (dark, sunken spots on the bottom of the fruit), curling leaves, and stunted new growth.

The fix: add crushed eggshells or agricultural lime to your soil before planting. Mid-season, a foliar calcium spray can help fast. And again — consistent watering helps calcium move through the plant properly.

3. Poor Airflow Around the Plant

Tomatoes need air moving through them. When plants are crowded or over-leafed, moisture sits on the foliage, fungal disease sets in, and pollination suffers.

Prune the suckers — those little shoots that grow in the crotch between the stem and a branch. Keep the lower 12 inches of the plant clear of leaves. Give each plant at least 24 inches of space.

Good airflow means better pollination, which means more fruit. Simple as that.

4. You Planted Too Shallow

This one surprises people. Tomatoes are one of the few plants that actually benefit from being planted deep — sometimes up to two-thirds of the stem underground.

Those little hairs on the tomato stem? They become roots when buried. More roots means better water and nutrient uptake, stronger plants, and more fruit.

When I plant, I dig a trench, lay the plant on its side at an angle, and bury everything but the top few sets of leaves. The stem curves upward toward the sun within a day or two.

The Bottom Line

If your tomatoes look healthy but aren't producing, run through this checklist:

✅ Am I watering deeply and consistently?
✅ Does my soil have enough calcium?
✅ Is there good airflow through the plant?
✅ Did I plant deep enough?

Fix those four things and I'd bet you'll see a difference within two weeks.

If you want to make watering easier and more consistent, take a look at the Tomato Crater® — it's the tool I use every season to make sure water goes exactly where the roots need it. Made right here in the USA.

Good luck out there. And remember — gardening isn't about being perfect. It's about paying attention.
