I have my namwah patch heavily mulched, and constantly add layers of manure, kitchen scraps, leaves, grass.. you name it. With each new layer i put down more wood chips. I dont mulch right on the Pstem, but leave that area clear for a few inches to prevent rot. I also fertilize weekly with about a 1/2 cup of 13/13/13 per plant. I further add potassium sulphate every 2 weeks. I really feel that good soil, and tons of organic matter are the key.. sunlight and water cant do much without a good root system to uptake nutrients and moisture. Most of my namwah are 13ft of Pstem, all of that growth since March/April. I have many other varieties as well, but the namwah are planted in the best prepared bed in the yard. The others are about 6-8 feet at this point in the season.
