Spring is here in the Ozarks. It could still frost, but days are warm. It’s time to start those garden tub greens.

Which Greens?

There are several to choose from. The big question is whether or not frost will still visit. That takes bok choi off the list for a couple more weeks.

Thumbing through my line of seed packets, I take out Napa cabbage, beets, kohlrabi, green onions, red and green lettuces, tatsoi, red and green mizuna and carrots. These should take a light frost.

Why Garden Tub Greens?

My garden soil is still cold. The tubs sit out in the sun and warm up. All of the greens I’ve chosen may like cooler weather, but they don’t like it cold and damp.

The one disadvantage is the size of the tubs. Some of these do get big, so I can’t plant very many. My other option is pulling some like beets early for just the greens.

Another consideration is how long these take to mature. Ozark springs can be long and cool. More often they are short and become summer almost overnight.

Planting the Tubs

My garden tubs have mulch on them. Most of this mulch needs to stay or the weeds will have a party.

So I clear a ring around the tub a few inches inside. Seeds are planted in this ring.

The weeds will still have a party. At least, they will try. But it will be a small party.

Succession

About the time these greens are ready to harvest, summer will be moving in. I can still grow greens in some of the tubs, but ones that can take some heat.

Most of the tubs will have peppers, eggplant and other summer crops to fill them until fall cools things down again.

I have written about using tubs in the garden before, but it bears repeating. Since I am filling garden tubs again this year, it’s a good topic as I’ve learned more about them.

The tubs I am writing about are the empty plastic tubs from cattle licks. There are lots of cattlemen around me and these tubs are popular ways to add nutrition for their cows. My feed store buys back the empties and sells them to people like me so they are not left to get trashed out in the fields.

Preparing the Tubs

Drainage holes are the first step. Originally I drilled several half inch holes in the bottom of the tubs necessitating use of blocks under them.

There are several difficulties with this approach. One is finding enough blocks, bricks or rocks to set under the tubs. Another is trying to pull the weeds that inevitably start growing under them.

I now drill these holes in the sides about two inches from the bottom. The tub can be set on the ground. The base provides a water reservoir for dry weather as tubs dry out fast.

Filling Garden Tubs

First and foremost is setting the tub where it will stay. Second is a layer of large gravel. I like some large, flat ones for over the drainage holes. The rest is fist sized or larger to a depth just above the drainage holes.

Then comes the dirt. It takes a lot of dirt to fill one of these tubs. My preference is a mix of dirt and compost. In reality, I use compost (sometimes pure in a pinch), dirt, sand and red dirt (clay). This last must be very well mixed in.

Using the Tubs

Most vegetables have shallow roots, so the tubs work well. One tub is sufficient for one tomato plant, three or four pepper plants or a ring of greens. I do put mulch on top to help hold moisture in.

The tubs do heat up when in the sun. I felt the dirt one sunny summer day and it was warm enough, if it was water, to take a bath. Vegetables don’t appreciate this.

I hang sun screens on tubs in the sun. Others I place so they get afternoon shade.

Filling garden tubs is work and they do wear out in five to ten years, but they let me grow many things I couldn’t otherwise – like carrots – and my peppers prefer growing in tubs.
