I decided to separate the young sulcatas because one is growing so much quicker than the other two. It's 30 sq ft in size, big enough to house the leopard with him.I am planting 2 types of spine-less cactus ,2 yucca plants, 1 bunch of sundrops, and a mulberry tree as the main plants for shade, and to nibble on. I removed all the regular cactus plants so I can plant the spine-less, but am leaving the weed grass in place.have some bamboo in flower boxes that will set on the wall to give shade in the evening sun. Here are some pics of before and how I am going to set the plants, hopefully this evening.That pile of cactus is what I dug out. Len
