How to Make an Air Pruning Bed 1: Plans, Shopping List, and Budget

 Budget/Shopping list:

Air Pruning Bed
PartAmountCost/PieceTotal
Untreated Douglas Fir 2"x10"x8'2$15.15$30.30
3'x10' 1/4" Hardware Cloth1$24.13$24.13
4' Untreated lath bundle (50)1$19.98$19.98
3 1/2 " screws1$5.98$5.98
1 1/2" screws1$1.28$1.28
Staples1$6.97$6.97
Pedestals - Cinder Block4$1.12$4.48
$93.12
Cover Cage
Untreated Pine 1x2x8 (furring strip)4$1.77$7.08
Wildlife netting, 100'x7'1$19.98$19.98
$27.06
Total Cost$120.18


Note, this is the cost for the 1st bed. You will have leftover hardware cloth, screws, and lath, so the 2nd bed will be less expensive.

We chose douglas fir, since it is more rot resistant as compared to untreated pine. Cedar would be best, or even black locust if you have access, since these woods are more rot-resistant. Whichever wood you choose, just make sure it is untreated to avoid having chemicals leach into the soil.

After reviewing videos on YouTube, like:

Twisted Tree Farm

Edible Acres

Oak Ridge Farmstead

we decided to go with 1/4" hardware cloth for the base, and to wrap the material around the bottom, onto the sides and reinforce with a simple piece of lath. Soil weighs an incredible amount! 

In fact, our original design was twice as big, at 8'x4'. However, after calculating that the beds would weigh over 1,000 lbs, we down-sized, just in case we needed to move the beds at some point.

To calculate the soil weight, first figure out your cubic feet of soil:

Length (in feet) x Width (in feet) x Depth (in feet) = cubic feet of soil

Then, multiply the cubic feet of soil x 80 lbs (assuming your dirt is loose and moist).


Next step is to make the beds!

DIY Wooden Garden Signs

 I was shopping for some natural-looking garden signs to add to my garden, but struggled to find something that I liked. I already had some old lathe and extra bamboo stakes laying around, and thought it would be perfect for making some simple wooden signs! It's biodegradable, unlike those plastic labels you get with the typical nursery plants. I had some garden twine (jute, I believe) to tie the bamboo stakes to the lathe. Perfect! I did purchase some special paint markers, since regular Sharpies do tend to wear off in the rain throughout the growing season.  Here's how I did it: Materials: Lathe Bamboo stakes Garden twine, jute or similar Paint markers Spray polyurethane (optional) Process: 1. Cut the lathe into desired length. I eyeballed about 3-4". I cut a few with a hand saw, but quickly switched to a battery-powered circular saw! 2. Sand edges and any rough faces. 3. Cut bamboo to desired length. I cut about 12" pieces using a circular saw, which did splinter t...

How to Make a Natural Rooting Hormone Using Willow

Big box stores sell a small jar of synthetic rooting hormone for only a few dollars, but many people want to avoid exposing themselves to this. A DIY alternative is willow water. Have you ever tried to cut down a willow tree, only to find a few months later that it is sprouting everywhere? This tree just wants to grow and roots so easily. You can take advantage of this natural tendency for rooting by making willow water. The magic behind this phenomenon is in 2 compounds that are found in willow trees: salicylic acid (the stuff in aspirin that helps with resistance to pathogens) and IBA (indolebutyric acid, which stimulates root growth).  First, find a willow tree...any variety of willow will work here. Willows love water, so check by ponds, rivers, and streams. The best time to collect would be early spring or summer. If you're collecting in the summer, you'll need to remove the leaves. Focus on getting the new growth - the ends of the branches that are thin and pliable.  Nex...
