It's been about at least 9-10 years since I started with 2 very small plants. The wire basket dirt and spaghnum moss worked fine in the beginning, then it grew larger and started to tip over from the weight. So I reattached new chains and hung it at 180 degrees from the original. It started pups on the top, bottom and backside completely engulfing the wire basket.
That's why I'll need the metal cutting ability.........and depth. The ball is about 18-24 inches of solid growth (old basal leaves) and the full width is about 6 feet in diameter all the way around. It is a definite conversation piece, and I'll be sad to have to divide it, but it just too huge. Been threatening to divide it for a couple years, but until read Ken's article and he gave me tips on dividing it, I feel confident it will be successful.
