I found this old information when i googled for info about root depth.
They talk about the length of the roots of some vegetables. Healthy and not.
Don't know if this will help.

Here is a link that might be useful: root diagrams

That root diagram book is really beautiful! I might just print some of the diagrams and hang them on my wall! Thank you!

Carol, I used a container that size for mixed mesclun last year. It worked fine. My only trouble was the dog knocked it over and I lost a lot of soil. I still had a decent crop for my salads in spite of that.

Thanks guys,
the root diagrams are very interesting,if you go by that,the container would not be deep enough,for onions any way,but Kat,you think it will be ok for lettuce?

This made me wonder about growing in pots,seems there would not be enough room for tomatoeS,but plenty of you do it,and it workes out fine.hmmmmmmmmmmm,i suppose i would need to fertilize,i really don't use any thing on any of my plantings,well, i do use my worm tea,ha ha

As you can tell, i am nervous about planting my veggies,i really want to have a nice crop to share with family.I planted a few store bought tomatoes last year,and only got about 6 tomatoes,from 8 plants.
Maybe i should add some manure,and tll it up,but then i will have a bunch of weed to deal with,hummmmmmmmmmm.

I don't know if you've heard this tip for tom's but here goes. I heard it on gardening by the yard, he said take a pen and tap the stem near the flowers to help them self pollinate. I just tapped them with my finger when I checked the garden. It worked really well. I had new tom's forming every few days.
I also saw a show that suggested mesclun and loose leaf lettuce for table top garden/center pieces. So I think your container would definately be ok for lettuce. Mine grew fine and only had three inches of soil after the dogs tipped it over. I guess it helped me thin them out, lol.

Lettuce will probably do fine. I grew lettuce in flower pots last year.

Carol, are you using those under-bed storage boxes? Sounds like it, which is what I put in my cold frames this winter. I sowed a lettuce mix, spinach, and carrots - don't worry, the carrots were short, lol! Made for window-boxes, actually. So I think your lettuces will do fine. Are you planning on cutting your lettuce as it grows, or harvesting heads? I cut it as it grows.

I think the onions might need a bit more depth though.

Good luck!
:)

Hi Dee,
Yep,i am using the underbed storage containrs,oh goodie, i will sow my lettuce in it then,i am trying to save on space.
I am in zone 5,Illinois,when do you think it will be safe to sow lettuce here?
Thank you,

I planted a mixture of salad greens again in the fall and they didn't die until the week before Christmas in my zone 6, although some mornings they were stiff and looked totally frozen. By noon they would look fine. I had them in a HUGE container in a somewhat sheltered spot, but they are pretty tough. I will be starting some very soon.

just 1morehosta last year i planted my toms in big white buckets I also don't like the "look" I'm thinking of spray painting them w/ some of that textured paint you know the kind you can spray on Terra cotta pots? By the way I had the worst tom crop ever, my fault I should of used better soil & fertilized more and now I wonder if they even got pollinated will try Floodthelast tip Thanks!!

Hi play,
I did see someone posted a picture of real colorful buckets they used,i just can't remember who it was.Maybe they will see this and chim in.
I don't want any thing i have to baby,fertilizing and pollinating by hand is to much work,when you have so much other stuff going on,IMHO,:0)
I just wanna grow some tomaotes darn it,lol
