Learning to Prune -- At Last!

Four years ago, we grew the Godzilla of tomato vines. We couldn’t stake it up high enough or fast enough to keep up with its growth.

It was a productive plant and produced fabulous tomatoes. But its branches were so thick we could barely reach in to grab the ripe ones without destroying the green ones. And we won’t even discuss the ones that were out reach inside the dark maw of this behemoth.

I swore after trying to tame that plant, I would learn to prune. And now, nearly two months after planting our pony packs of cherry and Roma tomatoes, we’ve done it! We’ve pruned!

Probably not enough and probably too late, but at long last I think I understand what needs to be removed: the suckers, the sprouting leaves that grow in the crotches (axils, if you want to be technical) between the leaves and the main stem.

I started pinching and clipping unsure if I was getting a sucker, a branch or a flower bud. But the more hands on time I spent with the plant, the clearer the suckers were to me. Eventually, I realized that even if I was clipping off flowers and buds, we had so many on the vine that it didn’t matter if I made mistakes.

I suspect our worst pruning mistakes were made weeks ago. We thought our cherry tomato plants would be small and bush like — determinate tomatoes. This type of tomato only needs to have the suckers removed below the first flower cluster. Pruning anything more than that won’t improve fruit size or plant vigor.

Our cherry tomato plants are clearly indeterminate. They have multiple stems and they are growing into tall octopi. Karen has done a great job of tying them upright to bamboo stakes. She’s also gone in a cut away branches so that more sunlight can get in. Right now the plants are producing and look extremely healthy.

The Romas are getting fat and colorful. They are much more civilized plants; not so tall and not so wild.

Gardening takes a lot of faith: faith you're doing the work "right enough" and faith that a plant will produce despite the mistakes you make. Time will tell what our pruning has wrought. More later.

Hand-Knit Trellis Now Ready for Climbing Foot-Long Beans

Just as the "June" gloom is starting to burn off, I finished my knitted trellis for the garden. It completely surrounds one of our bamboo tripods, with space at the bottom for tending the romaine lettuces growing within the tripod. It's knit out of nylon twine on US 35 needles. While the nylon has no stretch (the way a wool yarn does), the huge gauge has loads of give. The piece was knit flat with ties attached along one edge. It is tied to the tripod along one leg. One some early samples for a knitted plant trellis, I experimented with lace patterns. They look lovely, but I realized two things. One, once the plants grow up the trellis any knitting pattern is lost. Secondly, the plants and leaves need space to grow in and out of. I used a pattern for a shawl: k1, yo, k2tog and then repeat. I got lost a number of times: the yarn-overs drifted over other stitches on occasion. As this was a speed project that won't be visible ones the beans grow over it, I didn

Know Your Soil For Best Garden Results

I've always taken soil for granted. It was there. You put seeds into it. You put water on it. Plants grow and produce flowers, fruit or vegetables. Gayle Weinstein, author of Xeriscape Handbook; A How-To Guide to Natural, Resource-Wise Gardening , takes a different view: “Soil . . . acts as a highway between life and death, land and atmosphere, plants and animals.” It stores water, air and nutrients and makes it possible for an exchange of elements and chemical reactions to occur, she adds. She describes soil as being animal, vegetable and mineral combined. Here are six tests Gayle recommends for getting to know your soil. Grab a shovel and a quart jar. Dig up two cups of dry soil two-to-six inches deep from the areas you want to test. Gather a glass of water, dish washing detergent and paper towels. A soil pH kit, a meter or litmus paper will be needed for the final test.

Determinate vs indeterminate: why does it matter?

When Karen and I planted our 2020 garden, we made the one mistake you never want to make with tomatoes: we didn't check whether the plants we bought were determinant or indeterminate. Our assumption that the cherry tomato plants would be small (small tomatoes means small plant, right?) and the romas would be big, was 180 degrees wrong. The Great Green Goddess of Gardening was on our side, however. Karen has been able to stake up the indeterminate cherry tomatoes -- and the determinate romas have plenty of string fencing to grow on. I've been asked to write more about the differences between indeterminate and determinant tomato plants. Since I clearly needed to review, I'm glad to do so. In simple terms, determinate plants are like bushes or shrubs; indeterminate plants are like trees. Determinate plants are genetically set to grow to a certain size and stop. Indeterminate plants will keep producing stems, leaves and fruit as long as they get enough water, light and warmth.
