Have a pro onion tip that's worked for you? Let us know... 👀⬇

Unfollowed the advice from an onion gardener. She keeps the greens cut back to about 4 to 6 inches. Produces a bigger onion. Thought I would try it this year. I incorporated a time released fertilizer into soil before planting. After greens were about 4 inches I fertilized the onions with a high nitrogen fertilizer. Worked like a charm. My onions have never looked better and the size is larger than ever.

I find good spacing and a high nitrogen fertilizer is what makes my onions grow even in less than full sun. Someone pointed out that the bulb is actually just the bottom of the onion leaf so for healthy bulbs you need lots of nitrogen. It's not a root like a carrot or beet.

Record rain during winter here and still wet in the spring. Got 20 out of 50. Zone 6b. East Coast. USA. We are new at onions. First year yield was a much bigger harvest. We did trenches and put them too close. Live and learn. Thanks Kevin.

It would’ve been interesting to see if you fertilized the closer ones and didn’t fertilize the ones spaced out more

My neighbor keeps growing sets and I keep telling him... I mean I show him the onions I grow every year but he just refuses to get it. Grow from seeed!! it's so easy, onions are probably the most reliable, consistent crop I grow and I do the same thing every year, 100+ per square yard is possible.

my onions in my small containers did best. they were well spaced. Like 4 onion slips in planter similar size to that growbag in the video.
The ones in my raised planters did pretty well, but got stressed out by raccoons and flowered pretty early.
very rewarding plant to grow.

[CamilaMayumi]

Wow this video was a really time consuming and hard work! What an interesting experiment! Congrats.

[megslive]

hey kevin thjanks so much ironnicly I was just looking for a onion video on your channel because yours are always the most helpful and go into every detail ( and before this the cucumber video came when I was looking for that) thanks so much your videos helped me get my garden going, Keep up the good work!!!

[danagwena]

I'm growing onions rn. Thanks for the tip. Please try planting 147 bean plants. Just a random request😐😶

[pamelamercer]

Freeze dry them. It's one of the best things I do with my freeze dryer. So convenient for cooling!

It would be nice to see some experimentation with strawberries in the same patch. You can test the three varieties. Dappled light to full. Straw mulch to no straw mulch. Clay soil, to loamy, to sandy and maybe even in straight up hay.

Lots of folks say get strawberries, they're easy. I've found, yeah, after 2-3 seasons of making mistakes, they are easy. My initial problem was getting the soil, right so that the water and sun wouldn't be so much of an issue in my near-alpine desert climate.

An old timer gave me sweet italian red starts. He said use triple-16 fertilizer, keep watered, and to "nip" the tops off. Had pretty decent size bulbs, but I also had competition fron the rats. It was a so-so crop this year.

[asteria]

I wonder if adding the fertilizer a couple weeks after planting would be more fruitful than adding at planting? Wouldnt a lot wash away before the roots could get to it?

[Cottagecore_Hippie]

Thanks for this! I'm giving homesteading a try next year. I'm learning all I can to grow as much food for my family as I can.

[rinarose]

Super interesting to see how long the roots are on the grow bag onions compared to the in-ground ones!

[IbrahimMomoh]

Epic gardening video is a most watch for me. Thanks for sharing

[thelrb]

I would love a video on garden plants/varieties that do better in shaded areas. I live in an area where it is surrounded by massive trees so the sunlight is minimal for me.

[ventureroots]

Thanks for this video. Will definitely try some of these tips when I eventually tried to grow onions. I've heard they can be really finicky, so this helps.

Onions are 1 of the best "No Waste" vegetables you can grow. Green leaves chopped
for salads/garnish's, chopped and frozen, dehydrated and ground for granulated, or
ground onion in the pantry, and of course whole. No Waste, Period!
