Sand grape Crassula rupestris crassulaceae green lock dragon, transliterated as sand grape. Sandy grape is a perennial succulent herb, with clusters of plants, fine branches and fleshy stems, which will gradually become semi-lignified after a long time.

Morphological characteristics

The fleshy leaves of sandy grape plants are grayish green to light blue, the leaf margin is slightly emerald green, and the leaf margin will appear red in late autumn and early spring when the temperature difference is large. Leaves alternately opposite, ovoid-triangular, without petiole, base connected, new leaves superimposed up and down, with a little interval between adult leaves. The flowers are white and bloom from April to May.

Growth habit

Sandy grape native to South Africa, need plenty of sunshine and cool, dry environment, resistant to semi-shade, afraid of waterlogging, avoid muggy and humid. It has the habit of growing in cool season and dormant at high temperature in summer, so it is the "winter type" of succulent plants.

Training technology

From September to June of the second year is the growing period of the plant (the environment of the flower friend is different, the growing period is also short). If the light is not enough, the plant will grow too long, and the distance between the leaves will be lengthened, making the plant type loose, while the plant growing in the sunny place will be short and strong, and the stem nodes will be arranged compactly. It is necessary to keep the soil moist and avoid stagnant water during the growing period. The soil used cinder mixed with peat, a small amount of perlite, the proportion is about 5:4:1, the soil surface covered with small stones.

It can withstand a low temperature of about minus 2 ℃, which is the indoor temperature. If it is not in the open air, the top growth point of the lower leaf will appear frostbite, dry up and die, and new side branches will sprout again in the withered place in the coming year. The water is basically cut off throughout the winter, and the water will begin to be cut off slowly below 5 degrees. When the summer high temperature, the whole plant growth is slow or completely stopped, at this time to be well ventilated and properly shaded, avoid exposure, control watering, not long-term rain, so as to avoid plant rot. Grape in sandy land needs to be pruned frequently in the process of cultivation, cutting off disorderly branches to maintain the beautiful posture of the plant.

Reproduction method

The propagation of grape in sandy land is generally beheaded, take healthy branches with growing points, cut them according to a section about 3 to 5 centimeters high, dry the wound and cut them, or directly cut them in the dry granular soil with a small amount of water supply after a few days. It is a very good breed, and many small roots are easy to grow between leaves and leaves. When it comes to the right soil, it will take root firmly in the soil. Another advantage of beheading reproduction is that it can give the mother plant a better shape. Willing flower friends can give it a try. After beheading, new growing points will sprout again, and some will sprout two branches. If you cut off your head more times, the plant will show an inverted cone. Top-heavy, this is the time to use things to support.
