Crops in this Family: Apples, Strawberries, Almonds, Cherries, Plums, Pear, Peach, Nectarine, Apricot, Blackberry, Raspberry
Below is a tissue nutrient sufficiency table for the Rose Family (Rosaceae), which includes crops like apple (Malus domestica), strawberry (Fragaria × ananassa), and rose (Rosa spp.). This table provides macro- and micronutrient sufficiency ranges, leaf water content (LWC), and Brix values across key growth stages. Since nutrient needs vary across Rosaceae species, this table is a generalized synthesis based on well-studied members (e.g., apple data from Cornell University, strawberry data from the University of Florida, and other sources), adjusted for the family’s physiology.
Growth stages are defined as:
- Vegetative (shoot/leaf growth to pre-bloom)
- Flowering (bloom initiation)
- Fruit Set (early fruit development)
- Fruit Maturation (fruit growth to harvest)
- Harvest
Nutrient concentrations are in percentages (%) for macronutrients and parts per million (ppm) for micronutrients, with LWC as a percentage of fresh weight and Brix (°Bx) as soluble solids in leaf sap (not fruit Brix, which is a separate quality metric).

Scanning Recommendation:
- Ensure that over 25% of the scan bed is covered with a single layer of vegetation.
- Nutrient and LWC data are from fully expanded leaves (e.g., apple mid-shoot leaves 60–90 days post-bloom, strawberry mature trifoliate leaves).
- Leaf selection should be similar to these illustrations.

Apples:
