Harvesting: When onion tops have fallen over and turned yellow or brown, they are ready for harvest. Harvest in the morning, lifting onions with a garden fork. Dry them in the garden in the sun for 2 to 3 days, lightly covering the bulbs with straw, or the tops of other onions to prevent sunscald. Cure onions for 3 to 7 days in a dry area with good air circulation. Once dry, cut the roots to 1/4", and the greens to 1" to create a seal, preventing decay.

Great germination rate, almost 100%! The onion seedlings look very healthy. I used Fort Vee seedling mix, and am trimming the seedlings for better growth. I’m happy with these!

So what does matter to a home gardener when choosing a catalogue from which to order seeds? For me it is knowing that my order will be processed and shipped el pronto quicko. It is knowing that the germination rate of the seed I have ordered approaches 80% or higher. It is knowing that they are not about selling odd ball novelty varieties but about providing rock solid varieties with proven performance. They almost always have whatever I am looking for. Botanical Interests has been my go to resource for seeds for 3 years and they have never disappointed.
