Downspout trellis for climbing plants outdoor
Transform plain downspouts into a vertical garden with tall HDPE mesh and offset brackets.
This 108 in x 4 in HDPE mesh downspout trellis gives climbing plants like clematis, morning glory, and mandevilla a full-height support on the downspout. Offset brackets securely hold the mesh about 2 inches away from the pipe for airflow and healthy upward growth without rust, rot, or overheating.
Description
This surface-mounted trellis kit uses UV-resistant black mesh and offset brackets so vines climb in front of the downspout, not on it. The mesh doesn’t heat up in the sun like metal, and the slim profile fits beside gutters, corners, and tight side yards where other trellises won’t.
What’s included
-
9 feet of heavy-duty HDPE mesh (ships rolled, then unrolls flat)
-
3 Black composite mounting brackets sized for the mesh
-
3 Mounting screws for typical wood, vinyl, or metal installations
-
3 Stainless steel zip ties
-
Simple installation guide with tips for clematis and other vines
Installation & mounting
Most gardeners complete this installation in about 20 minutes or less using a drill/driver and household scissors.
-
Carefully untie the string and remove the loose black composite block, the small bag with button head fasteners, and the 3 stainless steel cable ties. Set these aside for the last steps.
-
Mount the top black composite block (the one with the attached screw) on the front of the downspout just under the gutter seam. Position it so the two button head fasteners press against the downspout. The special screw is self-drilling, so no pilot hole is needed.
-
Unroll the mesh. On the second black composite block, remove the long screw and the two button head fasteners, then re-insert the button head fasteners through the mesh and back into the block at the height you want your trellis to end. Start the long screw into the block so the fasteners again press against the downspout.
-
Pull this second block down until the mesh hangs straight. With a screw gun, start the screw at a slight angle until it bites, then rotate the block to tighten the mesh and drive the screw in fully. Trim any extra mesh at the bottom with household scissors.
-
Use the remaining mid support black composite block to add a third point of support. Attach it to the mesh with the two button head fasteners, then secure it to the downspout with the screw.
-
Install one stainless steel cable tie on each black composite block. Lace the cable tie through the mesh across the front of the block so it can’t slide off, then wrap it around the downspout and tighten by pulling the loose end while holding the collar in place.

Tips for clematis & vines
-
Choose a clematis or vine that matches your sun conditions and hardiness zone.
-
For clematis, look for medium-vigorous varieties that typically spread about 3 to 4 feet wide and reach 6 to 10 feet in height so they fill the trellis without overwhelming the downspout.
-
Keep roots cool with mulch or low plants at the base of the trellis while allowing the vine itself to climb into the light.
-
Gently weave new growth into the mesh instead of letting it wrap around the downspout. Once the vine starts climbing, it will usually self-train and grab the mesh on its own.
-
For very tall growth, pinch or lightly prune the tips once they reach the top of the trellis to encourage side shoots and fuller coverage.
FAQs
Will this damage my downspout?
No. The mesh and brackets are surface-mounted so vines grow on the trellis in front of the pipe, not on the downspout itself.
Can I cut the mesh?
Yes. You can trim the mesh shorter with scissors or snips to fit lower downspouts or shorter walls.
