The Best Ways to Store Onion Plants Before Planting for Optimal Growth

Onions are a staple ingredient in many dishes and can be grown in your own backyard. However, before you start planting your onion plants, it is important to know how to store them properly. In this blog post, we will guide you through the steps on how to store onion plants before planting.

Why is it Important to Store Onion Plants Before Planting?

Proper storage of onion plants can greatly affect their growth and development. By storing your onion plants correctly, you can ensure that they stay healthy and vigorous until it’s time for planting.

When Should You Store Onion Plants?

You should store your onion plants after purchasing them or if you have received them by mail. It’s important not to leave the plants sitting out in direct sunlight or extreme heat as this could damage the roots and leaves of the plant.

Where Should You Store Onion Plants?

The ideal place to store onion plants is in a cool location with good air circulation. A garage or basement would be suitable locations for storing onions as long as they are kept away from any heating sources such as furnaces or hot water heaters.

Steps on How to Store Your Onion Plants

Now that we’ve established why it’s important to store your onion plants before planting let’s go over some steps on how to do so:

Step 1: Inspect Your Onion Plants

Before storing your onions, inspect each plant carefully for any signs of disease or damage. Remove any dead leaves or broken stems from the plant but do not remove more than one-third of its foliage.

Step 2: Cut Back Tops

Cut back approximately one-third of each top so that no more than four inches remain above ground level; this will help reduce moisture loss during storage while still allowing enough light penetration for photosynthesis.

Step 3: Cure the Onion Plants

After cutting back the tops of your onion plants, allow them to cure for one to two days in a well-ventilated area. This will help reduce moisture loss and allow any wounds to heal before storage.

Step 4: Prepare Storage Area

Prepare a storage area by cleaning it thoroughly and removing any debris or clutter. Make sure that the storage location is dry, has good air circulation, and is cool (between 32-40°F).

Step 5: Store Your Onion Plants

Place your onion plants in a cardboard box or mesh bag, making sure not to overcrowd them. Stack no more than three layers of bags or boxes on top of each other. Avoid using plastic containers as they can trap moisture and cause rotting.


Now that you know how to store onions properly before planting, you can ensure healthy growth and development once they are planted in your garden. By following these simple steps outlined above, you will be able to keep your onion plants fresh until it’s time for planting season!
