Planting and Caring for a Vertical Garden {Part 4: #DigIn}

This is a sponsored post written by me on behalf of The Home Depot.

On Monday, I shared with you our tutorial on how to build a vertical garden.

DIY Vertical Garden Tutorial #digin #heartoutdoors

In today’s post (the last post in the series), I will show you how to plant the flowers in your vertical garden and how to care for the garden after completing the build.

We left off with our completed box.  You will want to grab the flowers that you chose.  (Read our tips on choosing flowers for a vertical garden here.)

You will now need to cut a small “X” in the weed block with a utility knife or razor.  (Be careful, kids!)  You want the “X” to be big enough to allow the plant to fit through but not so large that the plant falls out.

Move the dirt around a little to make room for your plant.  Grab your first plant and place it in the hole you just created.

Be gentle with the plant.  Try to keep the roots intact.  The plant should fit snuggly in the vertical garden but it shouldn’t be super hard to push in.  I caught the hang of it after planting a couple of the flowers.  Continue to plant the flowers until your vertical garden bed is full.  I placed one to two plants in each section of lattice.  It’s a little bare now but should fill in nicely as we head into summer.

Once the flowers were planted, I gave them a big ol’ drink of H2O.

Nate and I were both pleased at how well the Behr Weather Proofing Stain repelled the water.  (As you can see in the photo above.)  Long live the vertical garden!

Now comes the hard part.  You need to keep your vertical garden horizontal for about 3 weeks.  Why?  You need to allow the soil to settle and to allow the roots to take hold.

Unless you are an impatient blogger on a deadline.  A blogger who thinks it is lame to post a vertical garden horizontally for reveal photos.  We attached some ladder hooks to the back of the garden bed with screws and hung the garden on the deck for a quick photo op.

The flowers were beginning to get a bit droopy by the end of our 5 minute shoot.  We quickly returned the bed to the horizontal position where it will stay for the next couple of weeks.  We will water the bed as needed and apply fertilizer every month or two.  We should be able to use the bed again next year.  We will just need to apply new weed block and soil to ensure the growth of healthy plants.

This impatient blogger can’t wait to get the vertical garden hung back up and for the flowers to fill in.  Ike, on the other hand, is more concerned about sunbathing.

This vertical garden project has inspired me to tackle a Flower Tower, another #DigIn project from the Home Depot Garden Club.  And that project totally isn’t sponsored.  I’m just pumped to tackle it.

How to Build a Vertical Garden Tutorial {Part 3: #DigIn}

This is a sponsored post written by me on behalf of The Home Depot.  I know, a sponsored post.  But keep reading because the project is awesome!

Who’s ready to see our vertical garden?

DIY Vertical Garden Tutorial #digin #heartoutdoors

Fun, right? Well, it’ll be even more fun when it fills out.  Hurry up Summer!

Who’s ready to tackle a DIY vertical garden of their own?

We used the vertical garden plans from the Garden Club over at Home Depot.  There are written plans and a video on how to make the garden.  We found the video to be the most helpful.  We did notice that the cut list was incorrect and the material list was missing many items.  We added those in our tutorial for completeness sake.

FYI, there are many photos and steps to this project.  Don’t let the length of this tutorial scare you you away.  We just wanted to make the tutorial as complete as possible.  The build really isn’t super hard.  It is, however, a little time consuming. I think it took us 3-4 hours in total.  We’re happy with the results though so it was totally worth our time.

  • Two 3/4” PVC caps
  • Two 3/4” x 1-1/4” PVC reducing bushing
  • PVC glue
  • Silicone caulk (optional)
  • One bag (1.5 cubic feet) potting soil
  • Flowers (Read about our suggestions for choosing vertical garden flowers here.)

Cut List:
1”x6” whitewood

  • 2 @ 32”
  • 3 @ 15”
1”x2” whitewood
  • 2 @ 32”
  • 1 @ 15”
  • 1 @ 18”
1”x4” whitewood
  • Inside length: mitered at 45 degrees
    • 2 @ 28.5”
    • 2 @ 16.5”
1/4” plywood 32” x 16.5”
3/4” PVC
  • 1 @ 10”
  • 1 @ 24” (If you bought a 2’ section, you do not need to cut this piece.)
You will want to start by grabbing your cut list and cutting your boards to size.  (Or have the Home Depot cut them for you if you don’t have a miter saw at home.  Nate’s dad stores his at our house.  Super convenient.)

#digin DIY Vertical Garden Cut List

You can stain your project at any time.  I think it’s easier to do in the beginning and it gives the project a cleaner look.  We used Behr Weather Proofing Stain in Driftwood Grey.  It’s important that you choose a finish that is appropriate for outdoor projects.  The Behr Weather Proofing is a stain and sealer in one which will help protect the box from the elements.  I applied two thin coats. It’s also important that you wear your best paint shirt when photographing blog photos. (Go Hawks!)

Take the 2 lengths of 32” wood and measure down from the top by 14” and up from the bottom by 3 ½”. Place a mark at each location.   Now with the three 15” boards place one at the very top one at the 14” mark and one at the 3 ½” mark.  These boards will form the body and compartments of the soil bed.  With the exception of the board at the 14” mark secure these in place with 1 ½” exterior wood screws.

Take the piece of 16 ½”  x 32” plywood and secure it to the bed frame with wood screws or with Brad nails. This will form the back of the vertical garden.

Now it is time to add the holes for our drip irrigation system. We used ¾” PVC pipe, one routed to each compartment. Use a 1” spade bit to drill a hole in the top of the frame. This hole should be just off center.

Take the middle support we didn’t screw in previously and slide it up and flush with the top board.  Using clamps to hold the board in place, drill the hole for the lower compartment. Clamping the boards together insures that the holes line up perfectly for the PVC to pass through.

Remove the clamps and move the center support back down to the 14” mark and fasten it into place as you did the top and bottom.

Use a 1” spade bit to drill a second hole in the top of the frame. This hole should be just off center.  This hole will be used to provide irrigation for the top compartment.

#digin Vertical Garden

To build the frame supports, the 32” long 1”x2” are drilled into place along the top edge of the soil bed.  This frame will give us extra surface area to support the face frame.

Repeat this with the 18” long 1”x2” along the top and the 15” long 1”x2” along the bottom.

Now it is time to line the bed with a moisture barrier. This is to prevent wood rot and warping from the moist soil over time. We used a plastic drop cloth (2 mil) that stated it was waterproof.

#digin Vertical Garden

Line each compartment and secure the plastic with staples.  Cut away excess.

#digin Vertical Garden

Next we need to add the irrigation system.  Make “X” shaped incisions in the plastic liner at the 1” holes we drilled into the bed frame.

#digin Vertical Garden

Take the piece of 10” long PVC and push through the hole without the pass through into the second compartment. When it’s about half way in attach the PVC cap to the end within the box. Glue the 1 ¼” - ¾” reducing bushing to the opposite end (this will be the water inlet).  Repeat the process for the 24” long PVC line that runs into the second compartment.


#digin Vertical Garden

We applied a thin strip of caulk to the outside to help keep moisture from getting in behind the pipes and plastic.  Wipe away excess.

#digin Vertical Garden

Use a small drill bit to place drip holes along the length of PVC, rotating slightly after each one. Make sure to get a hole as close to the bottom as possible to prevent standing water in the line.  On the 24” pipe, you only need to drill the drip holes into the second compartment section of pipe, leaving the rest solid.

Now you are ready to add your soil. We filled the bed half way with soil and then wetted it down a little.  We did this to help settle the soil to ensure that we filled it full enough.  We then filled the bed with soil up to the edges. You should also shake the box a little to help the soil settle. Check out that heavy lifting.  Hercules, Hercules!

Next, cover the bed with a layer of weed block placed tightly across the top.  Staple in place.  Cut away excess.

#digin Vertical Garden

Now you need to construct the frame.  Using the mitered 1”x4” pieces, place pocket holes (using a pocket hole jig) on the outside edges of the 16.5” pieces.  Secure with clamps.  Attach together with pocket hole screws. Optional: You could bypass this step and attach each piece to the bed frame with screws.  We chose to use the pocket hole method because it creates a stronger and cleaner looking frame.

You now have a completed box and frame.  It’s time to attach them using Brad nails (or screws).

I told Nate to look like he was having fun.  That’s what I got.

You’re almost there.  We just need to add the lattice!

#digin Vertical Garden

Measure the inside of your box.  It should be 20.5”x16.5” but it could vary.  Cut your lattice with a circular saw.   Attach the lattice to the inner support with Brad nails or staples.

Vertical Garden Complete

Woo hoo! You did it.  Your vertical garden build is ready for flowers!  We’ll finish the series on Friday with planting the flowers, hanging and styling the vertical garden.
