Why it matters
Growers, packers, and exporters care about firmness and skin durability; stronger tissue improves pack-out and supports fruit quality during handling.
When it appears
Built through fruit development and pre-harvest.
How to identify it
- Soft fruit that bruises and handles poorly
- Weak skin prone to cracking
- Visual defects and poor pack-out
How to manage it
- Build cell-wall strength with Calcium Boost and Armour Boost; reinforce membranes with Cellular Boost; keep watering even.
