Tomatoes are one of the most rewarding crops for home gardeners, offering rich flavor and endless culinary possibilities. But what happens when your once-thriving plants suddenly stop producing? It can be frustrating—but often, it’s also fixable.
Here’s a comprehensive guide to understanding the key reasons behind reduced tomato yields and how to bring your plants back to life.
1. Understand the Tomato Growth Cycle
Tomatoes follow a clear developmental path:
-
Germination
-
Vegetative growth (4–6 weeks)
-
Flowering (around week 6–8)
-
Fruiting
-
Senescence (aging)
Each stage has different needs. For example, flowering requires more phosphorus, while early vegetative growth thrives on nitrogen. Misunderstanding this timing can lead to improper fertilization or care that halts production.
2. Pollination Problems
Tomatoes are self-pollinating, but without adequate movement from wind or pollinators (like bees), flowers can drop without forming fruit. This is especially a concern in greenhouses or during hot, still days.
Tip: Gently shake plants or use a soft brush to mimic pollination indoors.
3. Temperature Stress
Tomatoes are picky about climate. If temperatures:
-
Drop below 55°F (13°C) at night, or
-
Rise above 90°F (32°C) in the day,
…flowering and fruit set can be disrupted. Heat stress especially causes flower drop.
Solution: Use shade cloths in summer or protective covers in cooler nights to regulate conditions.
4. Inconsistent Watering
Too much or too little water causes blossom drop and fruit splitting.
Best Practice:
-
Deeply water 1–2 inches per week
-
Water early in the morning
-
Mulch the soil to maintain moisture
