Radish Surprise

A volunteer radish–I think it is a daikon–sprouted up in a little clear pocket of our yard. We let it go, ignored it. It grew bigger, and bigger, and bigger. Usually a radish is harvested early, so we never see how big they can get.

This one got huge, then burst out into hundreds of tiny purple flowers. Hummingbirds, honey bees and all sorts of flying insects visit it all day, every day. It has become one of the queens of the garden.

The picture below is horrible. The radish plant really is quite pretty,  the equal of any ornamental flowering shrub–but as bad is the picture is, it gives you some scale. See the bales of our straw bale garden behind it?  I think it must be pulling water from there, which accounts for its size and longevity. It’s gone a little past its prime now– a couple of weeks ago the blooms were thicker.

By the way, radish blossoms are tasty food for people, too.

Straw Bale Garden Tour Part I

In this vide we take you into the backyard for a tour of our straw bale garden.

We started rotting the bales in late April by adding blood meal. In May we added a balanced fertilizer and started planting the bales. In the video you’ll see the veggies we planted in early June.

The soaker hose you see comes from Home Depot. I’m pretty sure it is this stuff.

Every other week I add some fish emulsion to a watering can and hand water the plants to make sure they have enough nutrients.

Straw Bale Garden Part V: Growing Vegetables

It’s too early to call my straw bale garden a success but, so far, the vegetables I planted in the bales are growing. I got a late start on planting–I put in the tomatoes, squash and basil in mid May/Early June–just in time for the cloudy, cool weather we have here in early summer.

Check out the difference between the tomato I planted in a bale on the left, compared with a tomato in one of my raised beds. The tomato in the bale is doing a lot better.

The bales are home to organisms that support healthy vegetables: mushrooms and worms. When I dug into the bales to plant some chard seedlings yesterday I found a lot of worms. I had thought that straw bale gardening was like hydroponics–essentially fertilizer added to a growing medium. But the presence of worms and mushrooms indicates that well rotted straw bales are more like the kind healthy soil that supports a web of soil organisms that, in turn, help vegetables grow.

Some of the plants, like this winter squash, I planted as seedlings.

Others, like this cucumber, I sowed directly into the bales by making a little hole and putting in the seed with some home made seedling mix.

Again, the vegetables in the bales are doing better than veggies in my two remaining raised beds. The reason, I believe, is that the beds are depleted and the compost I added to them was low quality.

While more resource intensive than growing in the ground or raised bed, straw bale gardening has a lot of advantages for the beginning gardener. Integrating fertilizers into a straw bale is a lot easier than making high quality compost and a lot faster. While not a long term strategy, I’m looking forward to trying straw bale gardening again.

Picture Sundays: A Keyhole Bed and Straw Bale Garden in Texas

John W. from Kerrville, Texas sent in some pictures of his garden. John says,

This is my first year to use compost tea.  I am growing plants in two Keyhole Gardens, self watering 5 gal plastic buckets and two hay bales (coastal Bermuda hay) that have a wooden framework on top containing bulk landscaping compost from a local nursery. My plants are growing super fast and my tomatoes are loaded.  This looks to be the best garden I have ever had.

Judging from the fencing it looks like you’ve also figured out a way to deal with the deer. Thanks for the pics John and good luck with the garden!

Self-Irrigating Gutter Update

We’ll get back to our thoughts on responses to the Three Headed Hydra of Doom tomorrow, but for today we’re going to take a quick break for a practical post: Self-Irrigating Strawberries!

This spring I built a self-irrigating gutter (SIG) using two gutters based on a video by Larry Hall. You can see my original post about this project here. Essentially, it is a gutter filled with potting mix, sitting on top of another gutter filled with water. Every eight inches there is a 3 inch perforated pot filled with potting mix that hangs down into the water filled gutter. For mulch I used re-purposed billboard vinyl scavenged from a dumpster by my neighbor Ray.

The SIG works, but there have been a few problems. My strawberries, I believe, have a fungal disease called red stele (Phytophthora fragariae) which came either from the soil that came with the starts or from the planting mix I used. If I want to grow strawberries again I’m going to have to thoroughly disinfect the gutters.

The SIG is hooked up to a 55 gallon rain barrel. Unfortunately the lower gutter leaked around 50 gallons of stored rainwater down into the garage below (our house is on a hill and the garage is at street level). To prevent this problem in the future I put a manual irrigation timer on the barrel so that if there is a leak, I won’t lose all the water at once.

If I were to do this project again, I’d also use a refinement that Larry Hall just posted in the video above. This improvement on the design replaces the lower gutter with a 4-inch drain pipe. The drain pipe is easier to keep water-tight. And instead of using a gutter filled with soil I might use a series of pots (an idea that’s also in the video)–gutters are too shallow for most plants.

Despite the problems, I would call the project a success. In fact, I may expand my gutter system out onto the rest of the garage roo.
