beginner's corner “ When you do manually secure growing vines or other plants, select materials that won’t cut delicate stems, and tie or loop them loosely enough to allow for stem expansion as the plant matures." Even vining plants can develop side shoots and create prob- lems on a trellis if they aren’t carefully pruned. Cucumbers are a good example. Carefully removing suckers to maintain a single main stem can keep cucumbers and other vines on the straight and narrow, just like it can tame a sprawling tomato plant. When pruning some fruiting vines to achieve a single stem habit, use caution. All that side greenery isn’t necessar- ily extraneous. On the same Y juncture where you may find a sucker, which is characterized by its leaf development, you might also encounter essential growth like a tendril, flower, or small fruit. Familiarize yourself with the appearance of all the plant’s growth stages before you grab your shears or prepare to pinch. If you do want side shoots to develop, control their numbers to help maintain good air flow and curtail excess growth below waist level, where competition for light is fierce. Pay attention to the anchoring structure of the vines you’re installing, too. Instead of the tendrils we discussed above, some vines attach by hugging surfaces with elongated leaf stems, in which case they may prefer wider or narrower supports. Others use adhesive disks (yes, like glue) to attach themselves. These anchors are effective, but to make good contact, they need a textured surface rather than a smooth material like PVC or vinyl. Vines with aerial roots also require textured surfaces. Yes, a plant, even a vine, can be manu- ally secured using clips or twine, but taking advantage of its natural inclinations makes the job of maintaining a successful trellis easier. The plants will secure themselves, even though their choices may occasionally need some adjustment. When you do manually secure growing vines or other plants, select materials that won’t cut delicate stems, and tie or loop them loosely enough to allow for stem expansion as the plant matures. There are proponents of most of the popular securing material options on the market. Detractors warn that thin poly twine can cut plants, while natural fibers can only be used for a single season and may break under 118 grow cycle
