Our tomato plants long ago outgrew the measly cages we put them in, and have since taken over our entire herb garden and started spreading through the fence into our neighbor's garden as well. When it became apparent that our neighbor was eyeing the tomatoes on their side a little too keenly, we decided it was time to stake up the sprawling limbs.
The thing is, the plants grew well established in their chaos. Their limbs have interwoven to the point where you can barely discern the origin plant, and untangling them revealed a different problem: if we staked the branch up, it would be upside down. That is, the undersides of the leaves would be exposed to the sun, and the weight of the tomatoes on that branch would be resting back onto its stem. Can the branch/tomatoes survive this way? Or will all the leaves burn and the tomato fall off under its own weight?
