Probably because of two typhoons at the south of Japan, the temperature of past several days were lower than 30 deg C. This is like a little early autumn weather.
Whatever the cause is, my succulents seem to be able to catch their breath after severe horrible hotness and humidity for about a month.
Dioscorea Elephantipes, Elephant's Foot, or Hottentot Bread recovered from his hibernation during hot season, and started to grow fine string like vine. It will soon open up leaves having shapes of hearts. It twines around anything that touches, so I made for him a spiral support with an aluminum wire this year.
Albuca Spiralis "frizzle sizzle" did not lost leaves last summer, but this year one of the bulbs lost the leaves and went dormant. I think it is because the roots were damaged as the bulb was badly inclined by the weight of flower stalk when it bloomed this spring. But, it also started to grow leaves.
After the typhoon would go away, it will be hotter again. I wish they can tolerate the coming back of summer.
