Want big, flavorful garlic bulbs? Set your plants up for success in the fall, before the ground freezes! 

Many gardeners wait to fertilize in the spring, then wonder why their bulbs are small when they dig them up in the summer. Whereas our organic Garlic & Onion Fertilizer Blend is designed to be worked into the soil when fall planting, so your plants have plenty of nutrients available from the get-go. 

Quantity: Each bag is 2 lbs and covers about 25 row feet.

Planting with strawberries? Go right ahead! This 5-3-7 fertilizer is also well-suited for strawberry plants, and can be used throughout the whole bed in place of our strawberry fertilizer blend.


What's in it:

  • Slow-release nitrogen—Feeds steadily throughout the fall without pushing too much growth ahead of a freeze
  • Key minerals—Phosphorus, potassium, sulfur (the reason why onions make you cry and garlic smells pungent), and the other key minerals garlic & onions love
  • Biochar—Increases soil water and nutrient retention, preventing nutrient loss
  • Humates—Also boost nutrient retention and micronutrient availability, and improve soil structure
  • Kelp meal— Supplies trace elements and natural growth hormones to enhance bulb flavor, size, and plant resilience against stress.

All of the ingredients are certified organic.


How to use it:

Work into the bed at planting, typically October–November. If you are interplanting strawberries and garlic you may need to work it in a little bit earlier when you plant the strawberries (September-October). 

Note: This blend does not replace the need for spring fertilizing. It gives your plants a stronger foundation from the start, but you may still need to add nitrogen in the spring to get the bulb size you want.


Made by farmers who use this ourselves!

We grow strawberries and garlic on our certified organic farm in Carlisle, Ohio. This is the blend we developed for our own beds, custom-pelletized in small batches. No synthetics, no fillers, nothing we wouldn't want our kids walking through barefoot. 100% organic and kid safe.
