I've read about using old car tires to make a potato barrel planter. The concept is simple, where you place the tire on the ground, fill with soil, plant the seed potato, and then as the potato plant grows taller in the redneck potato barrel planter, you simply add more soil (like hilling) and add another tire. You continue adding soil and tires periodically.
Although we didn't start our potatos as early as we could have, we still got them planted in a reasonable time for our (USDA) zone 5 climate.
Of the reasons for the delay was, (1) I wanted to build two additional raised beds for potatos, and (2) I hadn't bought seed potatos yet.
The first photo is of newly planted seed potatos (cut into sections with 1 eye per chunk These chunks will be covered with soil and watered. The bottom photo on this page shows how these chunks had grown in 24 days in May. So the photo of the planting (and the planting) occurred on May 5.
We planted both of our black elderberry plants in the spring of 2010. We chose one "Nova" and one "York" elderberry plant due to the timing of their fruit ripining being slightly staggard, one from the other.
Both plants were surrounded with chicken-wire, but I didn't put landscape fabric around either of them until the summer of 2010 (should've done it sooner).
We laid out our blueberry bushes where all four bushes would be within 25 feet of each other.
In the photo, I've circled the four blueberry plants (for clarity).
The two in the foreground are expected to only grow about as high as the fence.
The two in the background are expected to grow about 6 feet tall and 6 feet wide.
All four plants are encased in chicken-wire, with the top covered with plastic bird-netting.
Both of our 2 thornless blackberry plants (planted from bare-root the previous year, 2009), had their primocane 'pruned' by rabbits or squirrels over the 2009-2010 winter.
The photos below show the spring growth of the "south" blackberry as of May 29.
In one photo, you can see how tall the canes have grown this spring.
In the other photo, you can see how the blackberry has grown through the holes in the chicken-wire (I was lax this spring with respect to blackberries).
The inverted cucumber trellis that we use is simply a retaining wall.
Instead of having the cucumbers plants grow 'up' in this location, we allow them to grow down the wall.
Over the past years, we've planted several cucumber varieties in this location and they've all grown well.
Essentially we've created our own little cucumber gardens where the cucumber seedlings can rest and grow.
