I started an experiment with asparagus seedlings back in June, hoping to jumpstart my asparagus patch. Now, in September, I have them growing indoors under a grow light, and while they were browning for a bit, I'm seeing new shoots coming up. Since these seedlings need a cold period and can't stay indoors, what are my options? Should I try to acclimate them to the outdoors now that it's getting cold, move them to the garage, or wait until they go dormant? Will they even go dormant if I keep them under grow lights, or will I need to make that happen myself?

I keep my asparagus in a greenhouse that doesn't go below 40°F, and they've been doing great. If your seedlings are getting too big, consider repotting them. Treat them like a houseplant and find them a nice spot. However, if you're thinking about transplanting them into the ground now, I would be cautious; it's probably not worth the risk.
Asparagus is pretty hardy! I’d say get those seedlings outside as soon as you can. They’ll handle the cold better than you might think.
Honestly, it might just be time to wrap up this experiment and let them go. From seed, asparagus can take 2-3 years to yield anything worthwhile. It's a long wait!
