I’ve been asked a lot recently about how to manage vegetative growth versus reproductive growth. On the mini-episode this week, I talk about which nutrients drive strong vegetative growth, and which drive strong reproductive growth and development, along with the hormonal interactions which drive plant dominance. Nutrients in both categories interact with and synergize or antagonize certain plant hormones. These interactions shape how trees and plants develop reproductive buds and fruitwood versus shoot growth. On this episode, I talk about which nutrients are vegetative, which are reproductive, and how to switch plant dominance between vegetative and reproductive stages.

4 Vegetative Growth nutrients:

  • Nitrate Nitrogen (not ammonium or urea)
  • Potassium
  • Chloride
  • Calcium

Reproductive nutrients:

All other nutrients will bring a slight reproductive response but the below 3 drive the strongest reproductive growth.

  • Manganese
  • Phosphorus
  • Ammonium
