I am going to plant Yukon Gold potatoes, Russet potatoes, carrots, beets, asparagus, and onions in the same garden bed (not a raised bed, just a big square of dirt in the lawn). My plan was to plant the asparagus, then the onions, then the russet potatoes, then the Yukon Gold potatoes, then the carrots, and finally the beets in that order. However, I read that carrots could stunt potato tuber growth, and that although onions are good next to potatoes, asparagus is not. Also, I read that beets may not be the best near potatoes. If I have a bit of space in between the potatoes and the carrots/beets, and the asparagus is across from the potatoes with the onions in between, will it be a problem? Is there a better order to plant everything? Also, I have a garden box and I am going to plant peas, cucumbers, and pumpkins in it. Is there a good order for those to be planted in? Thank you for your help.

You should put the tallest plants on the north side of your plot, so they will not shade the other plants.

I believe the reasoning for potatoes and asparagus not being good companion plants is that they are both deep rooted; unless you are interplanting them, it shouldn't be a problem. Ditto for carrots and potatoes.

Also, keep in mind that the asparagus will be staying in the same place for many years - it isn't something you plant each year, or move around.

So, for the crops you want to grow, I would put the asparagus on the north side in full rows.
Next I would plant the potatoes, also in full rows across the bed. (assuming you are planting enough to make full rows; there is really no reason you can't put the plants in using shorter rows - the main thing is to keep the taller plants to the north of the shorter plants, and leave enough room between the rows or patches to access your plants)
Next I would plant the onions, and then the carrots and beets.

Of course, you don't need to make all the rows going east to west, either; but I would definitely put the asparagus on the north side because the stalks get quite tall and you need to let them grow until late fall because that is what "feeds" the roots.

For your garden box, you will probably need to provide some support for the peas, and plan to let the cukes and squash trail over the sides.

I hope that helps a bit - and that other people will offer their opinions for you as well; happy gardening!

Thank you very much! That is very helpful. So if I leave a bit of space between the asparagus and potatoes, then it won't be a problem?

Best leave more space than you think rather than less.

I agree - the asparagus stalks get fairly tall and bushy, and the potatoes do spread out a bit underground from where the plant is, and you're going to need to dig them to harvest - you don't want to be digging up the asparagus along with them.
(I'd be inclined to leave at least 2 feet in between them, 3 feet if you have room.)

Ok - thanks. On a separate note, I decided to put just the pumpkins and peas in the garden box to give more space for the pumpkins to grow (and peas and pumpkins are companion plants, while pumpkins and cucumbers are not), and I was wondering if I grow the cucumbers in raised pots similar to hanging baskets, will the cucumbers be able to grow over the side and the cucumbers grow on the hanging vines rather than growing them from the ground and needing a trellis? Or do they work better with a trellis growing in the ground?

I am not sure cucumber vines are sturdy enough to hang like that.
Peas climb but only to 3-6 feet, and are kind of short lived here. Pumpkins will climb too if they see a thing to climb.

I'm generally ignorant of companion and antagonistic planting ideas.

regarding carrots stunting potatoes, well, the row of potatoes you plant will need about 3 feet wide of free space - I feel sure the vines will lay over a good 18 inches to each side, plus you have to move some dirt to dig them. So you cannot plant carrots 'on top of' potatoes - the carrots would never grow. Plant too close and you'll be stepping on other crops to dig potatoes. (The phrase we are looking for here is - Ask me how I know )

Are you in Alberta CA? Here is one site I found

I've never grown cucumbers in a hanging basket but I actually think they would do fine that way; I think I might have to try it just to see! Otherwise, I agree with everything Sally said above

As far as the potato vines sprawling over to the sides - they do; I use some small (cheap) border fences to keep things under control because I tend to make my paths a little on the narrow side.

I just m.easured my potatoes, the vines are laying over every bit of a 3 foot wide swath.

Ok - thank you to everyone - and the website above looks useful. I will remember about the potato spacing. The reason I thought hanging cucumbers would work is because I grew cucumbers in my garden box last year and the cucumbers grew well on the vines hanging over the side.

Well, there ya go! cukes
