Fertilizing Your Summer Vegetable Garden for Maximum Production

Summer is peak season for your vegetable garden—and if you want it to produce big, beautiful harvests, now is the time to dial in your fertilization strategy. Long days and hot temperatures mean faster growth, but they also create nutrient demand and stress.

In this guide, you’ll learn how to fertilize your summer vegetable garden for maximum yields using trusted products from Supply Solutions LLC, including fish-based fertilizers, calcium nitrate, and ammonium sulfate.

Why Summer Vegetables Need Strategic Feeding

During summer, plants are growing and fruiting at full tilt. This means:

• Higher nutrient uptake as crops grow rapidly
• More watering = more nutrient leaching
• Heat stress can reduce root function and mineral absorption

A summer fertilization plan keeps your plants productive, healthy, and resilient.

Top Nutrients for Summer Vegetable Success

✔ Nitrogen (N) – Drives leafy growth and supports fruit development
✔ Calcium (Ca) – Prevents blossom-end rot and improves root integrity
✔ Phosphorus (P) – Boosts flowering and early fruit set
✔ Potassium (K) – Increases fruit quality and plant durability
✔ Micronutrients – Prevent minor deficiencies that limit yield

Fertilizer Products to Use in Summer

• 10-10-10 Liquid Fish Fertilizer with Micronutrients – Great all-purpose support for most crops
• 15.5-0-0 Calcium Nitrate – Ideal for tomatoes, peppers, and melons
• Ammonium Sulfate (21-0-0-24S) – Provides nitrogen and lowers soil pH in alkaline conditions
• Compost tea or fish emulsion – For weekly boosts in organic systems

Weekly Feeding Schedule Example

Week	Fertilizer	Purpose
Week 1	10-10-10 Fish Fertilizer	Balanced growth and flowering
Week 2	Calcium Nitrate	Prevent blossom-end rot
Week 3	10-10-10 + Compost Tea	Strengthen fruit set and root system
Week 4	Ammonium Sulfate	Boost N and adjust pH

Repeat this cycle through harvest for consistent performance.

Application Tips for Summer

• Water before and after feeding to avoid stress
• Use foliar sprays in the early morning for fast results
• Keep feeding zones clean—don’t splash fertilizer on fruit or leaves in midday heat
• Apply every 7–10 days for fast-growing crops like cucumbers, zucchini, and leafy greens

Crop-Specific Guidance

Crop	Preferred Fertilizer
Tomatoes & Peppers	10-10-10 + Calcium Nitrate
Cucumbers & Squash	12-6-6 early, 10-10-10 during fruiting
Leafy Greens	10-10-10 weekly, light applications
Beans & Corn	Ammonium Sulfate or 10-10-10 as foliar

Real Garden Example

A backyard gardener fed their summer vegetable garden with alternating 10-10-10 and calcium nitrate. Results included:

• Larger tomato yields with fewer blossom-end rot problems
• Consistent green foliage and fruit production into September
• Less need for pest intervention due to healthier plants

Don’t Forget to Mulch and Monitor

Fertilizer works best when combined with:

• Mulching to retain moisture and prevent runoff
• Drip irrigation for even moisture and nutrient delivery
• Soil testing to track mid-season needs

Final Word: Feed for Flavor and Abundance

A well-fed garden is a productive garden. With the right summer fertilizer plan, you’ll:

• Boost harvests
• Improve crop quality
• Extend productivity into the late season
