Super easy, lots of fun.
- NOTE!!!! Before anyone comments about pressure treated lumber...READ THE INSTRUCTABLE, we already advise against it in there and just because the wood LOOKS like treated lumber to you, doesn't mean it is. It's poplar. Poplar and a non-white balanced cheapo camera!!! Leave it alone or offer to buy me a better one. And YES, I totally abuse my kids. We've already dealt with THAT too in the comments...so if your comment isn't about the topic at hand or not a question, with all due respect....keep it to yourself. Thx.
Step 1: Planning and Materials
MATERIALS we needed for 2 2'x4' boxes:
- 3 pieces of 1"x6"x10' lumber*
- screws (we used 2" decking since we had some laying around)
- covering for the bottom (we used old window screen, but plastic, fabric, plywood would work too)
- industrial screws
- compost, newspaper, potting soil of choice (See Bartholomew's site @ http://www.squarefootgardening.com for his super mixture. This should probably vary depending on what you will be growing though.)
- Plants and/or seeds
- Saw (we used a jigsaw since we are masochistic...I mean live in a townhouse and don't have the room for a table saw)
- Industrial Stapler
- Electric Screw Driver
- bonus for reclaimed lumber, but sadly since the building slump hit our area pretty hard and we haven't had any hurricanes (knock on wood) recently, recycled/reclaimed lumber is hard to come by. Use poplar if you can afford it, some plants dislike pine and pressure treated could release chemicals into the soil (or so I heard).
Step 2: Playing With Wood
The theory is, start the potato plant on the same level as all the other plants and as the sprouts break the dirt level, keep adding more dirt in the extended. So instead of only having 6" of growing room, an additional extender increases the space by 6" and with two additional, we'll have 18" of dirt for the potatoes to grow through.
So in total we had two 2'x4' garden boxes and 4 1'x1' extenders, for a total of the following cuts of wood:
Four 2' pieces
Four 4' pieces
16 1' pieces
Step 3: Screw it
Step 4: Staple your screening
Step 5: Fill 'er up
Step 7: Measuring
Step 8: Create a grid
Step 9: Planting and maintaining
Plant according to your plant's directions, for example if you are suppose to plant every 12" apart, place1 plant in each area, 6" apart = 4 plants/area, etc.
Comparing 4 plants in a 1' square area compared to 36" needed for row gardens plus the space for walking between the rows...this method seems to be a great idea for gardening, plus if you ad a plywood bottom and legs, you can bring the planters up to wheelchair height.
