That might work with older crops but could be challenging with younger crops. You could read this post https://growinginthegarden.com/how-to-water-your-garden-with-flood-irrigation/ for more information about using flood irrigation in your garden.

I’m in Phoenix and lucky to get irrigation. I’m trying to plan my first garden. Would a sunken basin work with the flood irrigation I get almost every other week?

Hi Catherine,

Thank you for the question. I lived in Boulder for a little over 5 years, and gardening there is certainly tricky and unpredictable! I remember the early and late snowstorms and the hail! Although we have more caliche here than clay, I have had to consider drainage in my garden as well. I would recommend you do a simple drainage test after you’ve got the basin bed dug, but before filling in any soil. You can do this by filling up the bed with water to the top with a garden hose and then letting the water sit for 24 hours. If it drains completely after 24 hours, then it should be fine for growing what you choose to in without worrying about it. I do this each time I want to plant a new bed, tree, or shrub to check the drainage. It’s a simple place to start and will quickly show you if any additional things need to be done. If you find it doesn’t drain, let me know in the comments here and I can give you some additional advice to improve the drainage.

Happy Gardening!

Kara

I live in the arid and high alititude of 6000+ of Denver, Colorado. We suffer from hot summer days, colder nights, low rainfall, and very low humidity. We say we live in the high desert here at the beginning of the eastern great plains. Let me preface this by saying we get hot and dry very quickly in the summer! We are also a mile high closer to the sun which doesn’t help either.
I have multiple raised beds and containers and have found ways to successfully garden here with lots of frost blankets, shade cloth, and of course, city water. We do have rain on occasion in the summer, but it is usually an absolute downpour (no gentle, sprinkling rains).
I have been fascinated with your sunken basin beds since watching you put them in and subsequently growing in them with great success. I have an area to put in at least two 4 x 4 sunken basin beds but did hope you may be able to answer a few questions.
We do have some clay soil and definitely a clay layer about 10″ down when digging in general, So in removing 4″ or so and amending the soil, would having this sunken basin area act like a bathtub? As a just in case, are there particular veggies you could recommend that can tolerant a moister soil in that situation? I was originally thinking about a 3 sisters garden or brassicas, but honestly, I am open to anything. I also have trellises available so I can go up with other veggies too!
Any guidance would be appreciated! Love your YT channel, btw!
Thank you!
Catherine

Yes, you’re right. Periodically watering extra deep will help flush salts. Same principle applies to sunken beds.

I’ve heard that can be a problem here (I’m also in AZ). Have you researched this at all? I’m thinking periodically flushing the beds with extra water to wash any salt buildup out the bottom should work, but I don’t have much experience with sunken beds yet. Do you have any thoughts?

Generally, you can pull them off pretty easily when it’s time to remove the plants. You may have to cut the vines in a few places, but it doesn’t take very long to remove a large amount of plant material.

Just rip them out? weave them back through all the holes?

@brenda chilson,

Hi Brenda, thanks so much for your question.

Soils aren’t consistent in the low desert. There could be a couple of reasons you’re struggling to dig.

The first is caliche. Some gardeners have a thick layer of caliche that is very difficult to dig through. I’ve known some who’ve used a jackhammer to penetrate through it. Caliche is a layer of compressed calcium carbonate that is like concrete and which prevents proper water drainage. If you see a layer of white material as you dig a hole, it’s likely caliche. It’s recommended to remove it as you dig it up. It’s possible you have caliche in your gardening area. I don’t have much of it on my property, but in the few spots I do, I used an auger to punch through it.

The second is that the high temperatures and low moisture in the low desert bake and compact the soil over time, making it very difficult to dig into. There is a little trick I’ve learned to make that much easier. If you’re planning to dig, soak the area with a sprinkler or garden hose turned on low. The water will soak into the soil and soften it. It may look muddy afterwards, but by the next morning or afternoon, it will be soft and moist, but not muddy, and much easier to work with. This is what I did.

I practice the no dig method after building my garden beds. However, the first time I turn over the soil, I use a tiller to make quick work of it. The one I use is a very small one. If you don’t own one, maybe you could rent one or borrow one from a friend. After that first time, I don’t till again because it disturbs the mycorrhizal network in the soil.

Here are links to the two tools mentioned above:

I hope this helps! Happy gardening!

Rabbits, chimunks and snakes, as well as thrasher birds. So we have to do enclosed as well. I dug holes for plants I brought from Oregon with a pickaxe in our courtyard and ended up with carpal tunnel and shoulder issues! Curious how you dug the holes??!!
I think we will have to go with raised beds with that being considered.
