About 2 months ago we bought a beautiful "Tetrastigma voinierianum" also
known as "chestnut vine" or "lizard vine". We placed it in shadowy spot and
it immediately started growing new branches. So we were happy that the plant
feels ok. But now, it is getting a lot of yellow leafs that eventually dry
out and drop off. It looks liek the plant is dying. We do not know why. It
still grows new branches but the core of its mature leafs goes away. Is
theer anything we can do to stop that process ?
