Trellis for Heavier Items

Post  Chopper on 5/5/2010, 3:46 pm

Do you think the typical conduit/nylon netting trellis is strong enough for cantaloupes and watermelon?

Certainly yes to the conduit, but I used a cattle panel instead of trellis twine for the Israeli melons and spaghetti squash "just in case". I think the worse that would happen is you'd need to cradle the melon and attach that to the crosspiece of the conduit.

The woven nylon "cord" netting that I've seen for the trellises can probably hold about ten melons on a single string (if you tied them all up in something and tied the string to it). Heck, it may hold 20-30. That stuff is stong. I'd worry more about the structure itself. Nylon is ridiculously strong. It may stretch some, but it won't break on you.

Excellent. Thanks for the input! Now I can obsess and worry about the next thing...

I decided to look into it a bit further, and found that the nylon thread my wife uses in her sewing machine has a tensile strength of almost 10 lbs. Nylon sewing thread for a home-type sewing machine can go up to 25 lbs or so.

A double braided nylon cord at 1/4 inch diameter can hold 1500-2000 lbs. Obviously this isn't what the garden trellis nettings could hold, but if even the lightest weight nylon sewing thread can hold almost 10 lbs I think our trellises should hold pretty well.

I also saw that as far as "cordage" goes, the outside of nylon cordage has a low abrasion risk, as does the cordage on the inside. So, should be a great all-around material that doesn't harm the stems or fruits/veggies.

Overkill

Post  SirTravers on 5/5/2010, 8:09 pm

I guess I have somewhat of an overkill. Since my neighborhood is new there is an abundance of leftover construction materials. I grabbed several panels of the grating they use under the concrete for driveways.
I ripped a 8 foot 2x6 in half and used roofing nails to hang the grating on the boards after I nailed them to my box. hehe.

I wish I could get some leftover building materials! With the price of plywood so high these last few months, I actually picked up 2 8 ft 1x12 boards and cut them to four foot lengths. I used those as my box bottom, because I had to put it on a hill, so had to raise one side up 12" off the ground and needed a sturdy bottom!

With a 1/4 gap between the 1x12 boards, I imagine I may have to water more often than usual, but it saved me quite a bit of cash! And on the bright side, I didn't need to drill drainage holes . . .
