Building a Garden Shade

Summer is a tough time in Florida to grow vegetables but there is a solution, by shading your garden you can keep the intense sun from damaging your plants. I’ve successfully used a shade cloth canopy over the last two years and have had good production throughout summer. There are a few things that won’t do good as they will bolt from the heat (romaine lettuce for example) but many other plants grow and produce just fine.

Recently I’ve had a friend ask about purchasing a cheap carport cover from Harbor Freight tools to use as a garden shade. I have had experience with this cover but not for a garden. The frame of this cover is made from painted steel which rusts very quickly and the cover is too shady for plants, I’ve found a 40% shade works well.

Here is the list I put together with links to the products to make a good quality 10’x20′ cover. The plan is easily modified for different sizes, my garden has a 20’x20′ cover. Here’s a drawing showing the main components:

Garden canopy frame

Links to components:

(4) Low peak corner fittings (red)
(2) Low Peak Top End Fittings (green)
(2) Low Peak Side Fittings (blue) 
(1) Low Peak Top Center Fitting (gray) 

Optional (6) footpads (brown) – I use these but you can just plant the pipes right into the ground if desired. Attach some sort of weights to hold the frame down in high winds.

These are all 1  3/8″ pipe connectors, this pipe is also known as chain link top rail. You can get this at any hardware store but the best deal will be at a fencing supply company. For a 10×20 as above you would need:

(6) Rafters @ 5′ each
(6) Ridges @ 10′ each
(6) Legs at whatever height you want, I used 6′. Add a little more if you are going to shove them into the ground.

This builds the frame, it is all galvanized and should last you many years if not a lifetime. The connectors can also be reused for different sizes and configurations. The final width of this design will be slightly less than 10 feet due to the rafter slope but it will be very close. For the shade cloth:

10 x 20 shade cloth 40%
9 inch Bungees

They also sell a 6 inch bungee but the longer ones are easier to set up, you can wrap it around the pole an extra time to shorten it if needed. The shade cloth will probably last 4-5 years from what I’ve seen so far, the bungees about 2 years. Harbor Freight tools sells a grommet repair kit for around $4, it’s a good investment for shade cloth repairs.

Also, check Craigslist and Facebook marketplace for used top rail. You may be able to save $$ this way.
