| Strange as it sounds, it turns out much of the damage to my nephew's plants was caused by birds--I believe finches--eating the leaves. I've witnessed it firsthand as have others. It's also been reported a number of times online. Below is a link to the Sacramento Bee which describes the problem. Anyone else experience this? By the way, to my amazement my nephew's plants have mostly recovered. They are now over 8 feet and still growing. |
