Seasonal Feeding Schedules for Maryland’s Cannabis Climate

Growing cannabis in Maryland means dancing with four distinct seasons - each bringing its own quirks in temperature, humidity, and growth potential. Whether you’re growing outdoors in raised beds or indoors near a bay window, aligning your feeding schedule with the rhythms of the season is essential to producing full, flavorful buds.

This article lays out a seasonal cannabis feeding calendar built for Maryland’s unique climate, focusing on organic nutrients, adjusting to weather shifts, and keeping your soil alive all year long.

SPRING (March – May): The Wake-Up Phase

What’s Happening:

• Germination and early vegetative growth
• Soil warming up
• Rainfall increasing

Feeding Focus:

• Nitrogen-rich amendments to fuel early leaf growth (e.g., composted manure, blood meal, alfalfa)
• Microbe boosters to re-activate living soil after winter (e.g., worm castings, compost teas)
• Light applications of liquid kelp or fish emulsion for balanced early nutrients

Tips:

• Apply granular nutrients around the root zone after transplanting outdoors (late April–early May)
• Use mulch to stabilize early spring temps and retain nutrients

SUMMER (June – August): The Power Phase

What’s Happening:

• Fast vegetative growth (early summer)
• Flowering begins (late summer)
• Hot, humid conditions

Feeding Focus:

• Mid-June to Mid-July (Veg Phase):
• Continue high-nitrogen feedings, but begin introducing calcium and magnesium
• Add silica for stem strength (important with Maryland wind/rain)
• Late July to August (Pre-Flower & Flowering):
• Gradually reduce nitrogen
• Increase phosphorus and potassium for bloom support
• Use bat guano, bone meal, or bloom-specific organic teas

Tips:

• Watch for nutrient leaching after summer storms
• Use foliar sprays early in the morning if plants are struggling with uptake

FALL (September – November): The Finish Line

What’s Happening:

• Flowering and ripening
• Cooler nights, possible early frost by late October

Feeding Focus:

• Use PK boosters (like langbeinite or seabird guano) for final flower swelling
• Incorporate sugar sources like molasses to feed soil microbes and enhance terpenes
• Stop feeding 2–3 weeks before harvest to flush out excess nutrients

Tips:

• Begin harvest preparations in October
• Cover plants or use row tunnels to extend harvest if early frost threatens

WINTER (December – February): The Reset Phase

What’s Happening:

• Dormancy for outdoor growers
• Indoor growers often run small winter cycles

Feeding Focus:

• No feeding outdoors - focus on soil amending and cover cropping
• Amend beds with compost, lime, and minerals to recharge for spring
• For indoor: use a mild, veg-friendly nutrient blend if running autoflowers or clones

Tips:

• Grow winter cover crops (like clover or rye) in your raised beds
• Store leftover nutrients and check expiration dates before spring
