Waiting to Garden...

Spring is in the air, the Vernal Equinox is in only 2 weeks (March 20, 2011) but the weather is still very winter-y. I have been itching to get out in the garden.


A confirmed Plant-a-holic, I have houseplants to keep me occupied in the winter months, but there is nothing like getting out and digging in the dirt. We have had a large organic vegetable garden for the past 42 years and expect to have one until I die. But I have to admit, gardening our sloping mountain terrain was getting to be more work every year.

So we have been working on making our garden easier to work so we can be happy playing in the dirt as long into our future as is possible. This is a multi year project, of which 2011 is year 3.

Our garden is about 1/8 of an acre. In 2009 we built a retaining wall and leveled out the top 2/3 of our garden area. This had a downhill slope of 6' from top to bottom, not to mention the differences side to side. We built a 4' tall wall and dug down 3' at the top. This required moving a LOT of dirt!

The Skid Steer moving dirt!

Moving this much dirt is more than a shovel job, luckily we were able to get a Skid Steer to use. We carefully pushed all the top garden dirt with years of mulch & amendments to one side as we dug down into the thick clay that makes up most of the land here.

The area where the wall went needed to be level, with a big enough area to put in drainage behind the wall. Then we could begin to assemble the retaining wall block by block. The wall is of landscaping blocks that lock together, and requires no mortar.
Once the wall was built up we backfilled it with the dirt we had set aside and some topsoil we had trucked in from elsewhere. We left a wide sloping  path up one side to run wheelbarrows up to the top of the garden.

Garden steps and beds with mulch

There was still some steep slope beyond what we had planned on with the wall, so we put large rocks and made stairs for access to this part of the garden.

By now we were itching to get our plants in the soil, and the first part of our plan was actually accomplished! I cannot tell you how much easier it is to work level ground than the free form terraces with the endless raking they needed.

Finished wall with garden & dedicated flower row

In 2010 we did phase two of our plan. This required making three broad terraced areas out of the remaining bottom third of the garden and starting to install raised beds. We purchased raised bed kits from Naturalyards, as we wanted to take advantage of those who had a lot of experience. This was far too important a project for us to reinvent the wheel, and we learned a lot. We really wanted to make these beds gopher proof (see our earlier blog on Gophers - not for the faint of heart...), and try to keep out the noxious bindweed that plagues us here, as well.

Attaching hardware cloth to the bottom of the bed.

Our plan was to attach weedcloth, and then 1/2" galvanized hardware cloth, to the bottom of the beds before installing and filling them. This won't last forever, but it will last a long, long, time. We have a hardware cloth lined bed in our greenhouse that we installed in the 1990's and is still intact.

Assembled bed showing the cross braces

One of the important things we learned about raised beds is, if they are longer than 6 feet, you need to have cross bracing to keep them from bowing out when they are filled with dirt. These beds are assembled with aluminum rods (aluminum won't rust) that are driven down through pre-drilled boards. Where there is a joint between two boards of a long bed you insert a metal strap and run the rod through that as well, to hold it in place.

Another thing we discovered is how much better it is to have a top trim on the bed so you have a place to sit or place tools or harvest baskets.

We use drip irrigation (from DripWorks) in the beds and T-tape, another form of  drip irrigation, to the beds in the terrace for ease of irrigation and conservation of water.

These changes have been a complete success. We raised onions, greens, cabbages, beets, broccoli, and the most perfect gopher-free carrots we have ever grown, in these beds last year. Currently we have fall-planted garlic and cabbage, as well as this years onions and beets in the ground. The terrace behind the retaining wall has proved easy to work and had a fabulous harvest of corn, tomatoes, squash, beans and other larger crops. On top of that, it was easier than it has ever been to keep our garden going

If all goes as planned, we hope to build 2 to 4 more beds this year. In every way these changes have met or exceeded our expectations, and I see wonderful fresh vegetables and flowers in our future.
