Organic Spinach Seeds

Grow your own nutritious greens with our Organic Spinach Seeds! These seeds will sprout into delicious spinach, perfect for adding to salads, smoothies, and more. These seeds are organic, non-GMO, and heirloom so you can grow the highest quality harvest.

Instructions: 

We recommend using the following to sow the seeds: 

• 12 Cavity Greenhouse or Planter with Humidity Dome
• Soil Pods 
• Liquid Fertilizer 

Spinach prefers cooler climates, and this particular variety does best in winter. In fact, if it’s too warm, they’re likely to “bolt”. Spinach is a fast-growing plant, and as such would benefit from some fertilizing.

The best method for doing so is to harvest the outer, older leaves so that the younger leaves have time to grow in. This variety works great in salads or in cooking.
