Tomatoes – Thin Stalks
Q: I grew both Big Boy and Better Boy plants in a small raised plot While I got some fruit, the plants were very tall and the stalks were thin and grew to heights in excess of eight feet. Was it a watering problem or a fertilizer problem?
A: Assuming the plants were in full sun, I’d guess it had to do with fertilization. Extra nitrogen causes a plant to grow leaves and stems. Fertilizing too often causes a tomato to grow very tall without making many blooms.
