GrowScripts Olive Tree Fertilizer Calendar

For container-grown olive trees (1–10 gal pots)
(Use with 18-6-12 CRF, Essential Trace Elements, and Calcium Nutrient Solution)

Month Feeding Focus What to Apply Why It Matters
January Rest / Cool Weather No feeding. Keep soil lightly moist. Olive trees slow growth in cooler months; roots rest and recover.
February Wake-Up Feed Apply ½ pouch 18-6-12 CRF + Micronutrient Feed Recharges roots before new shoots and buds emerge.
March New Growth Apply 18-6-12 CRF (start of 6-month feed) + Micronutrient Feed Fuels active shoot and leaf expansion.
April Bloom & Fruit Set Apply Calcium Nutrient Solution (foliar or soil) Reduces blossom drop and strengthens fruit formation.
May Active Growth Continue Micronutrient Feed every 2–3 weeks Maintains balanced leaf color and strong canopy growth.
June Peak Feeding Mist with Hydration Boost+ weekly; add Cal-Mg mid-month Supports nutrient uptake and reduces heat stress.
July Fruit Development Light Micronutrient Feed + steady watering Keeps fruit sizing and foliage balanced through summer.
August Late Growth & Second CRF Apply 18-6-12 CRF (2nd 6-month feeding) + Calcium Nutrient Solution Builds reserves for next year’s bloom and oil production.
September Fruit Ripening Maintain Micronutrient Feed once Supports late fruit color and oil accumulation.
October Transition Apply final Micronutrient Feed Strengthens branches and roots before cooler weather.
November–December Rest/Micronutrient Feed No feeding but Micronutrient Feed. Water when top inch of soil is dry. Allows roots to rest and prevents salt buildup in soil.
