These cylindrical wire structures surround the entire plant, providing ample support from all sides. As your Cherry Tomatoes grow, gently guide the branches through the openings in the cage so they stay upright and avoid breaking under their weight.

Another technique is pruning. By removing some of the lower branches and suckers (small shoots that emerge at leaf joints), you can redirect energy toward fruit production instead of excessive foliage growth. Consider using trellises or arbors for vertical support. These structures offer a more decorative solution while giving your Cherry Tomatoes something sturdy to climb on.
