Onion Plants Buyer's Guide

Also called onion transplants

Onions, leeks, and shallots – all relatives in the Allium genus – are some of the easiest garden plants you can grow. Whether you require short-day onion plants for the South (10-12 hour day length) or long-day onion plants for the North (14-16 hour day length), you can successfully grow your own crisp, flavorful onions right at home. Since they are relatives, leeks, and shallots can be grown and used in ways similar to onions – from planting to eating. All onion plants are multi-purpose vegetables in the garden since they work to repel rodents that tend to find the bulbs unappealing. Of course, the best part is you will harvest delicious, full-sized onions, leeks, and shallots all in the same year they’re planted! Since they store well, you can enjoy these homegrown vegetables any time of year.

To ensure your growing success and satisfaction, there are a few things to consider when you buy an onion plant.

Most onion plants are available only during the spring ordering season. In addition, many onion plants have a deadline for ordering that is before the normal spring ordering deadline. Be sure to check the individual onion plants to see if they have specific order deadlines.
