This succulent became a problem for my garden (Athens, Greece, zone 9, near the sea). It was more than 2 m high (6,5 feet) and the bush was more than 3 m. (9,5-10 feet) large. It was difficult to keep its growth under control. Finally we decide to eradicate it. This task was much more difficult. Now we have a small one in a pot and a free space in our garden.
But today, 4 years after the eradication, no plant can grow there. I am searching if "Aco subulata" has an allelopathy factor that impede other plants to grow. In the same place we have planted a Jasminum nudiflorum, then a Buddleja davidi and finally a Bougainvillea spectabilis. None of them succeed.

This is the fastest growing cactus I own and living in Australia, it gets plenty of sun and I have covered the soil surface with sugarcane mulch, and it keeps the plant cooler than normal, it seems to be the key to the growth rate.
Does anyone else use mulch instead of the small rocks or grit? And have you had any luck?

Mine is less than a foot tall so I'll have to be patient to see how big it will grow!
According to George Hull (Glendale Public Library) the asparagas cactus is:
Hardy in USDA zones 9-10. Should be planted in full sun. Native at higher elevations up to 12000' in Ecuador and Peru. This is one of the tree-like cacti growing up to 13' tall and 10' in diameter. Leaves are narrow and up to 5" long.
Update 8-28-04: The local critters (rabbits and round-tailed ground squirrels) just couldn't resist it. Such a shame, I really like this plant. *sigh*
This is a great cactus!! Once established it grows very rapidly. I was told this specimen could reach a height of six foot tall four feet wide. I have had no problems with it and it take full sun where I live.
