There are so many peoples, who want to know, how to grow the most beautiful Cactus. Cacti are fun to grow because of their eccentric, even comical shapes. They are extremely beautiful especially when they bloom. If your air is dry and you have trouble growing plants that like high humidity, put away your mister and pebble-filled trays and try cacti instead.
They also need less attention than other houseplants. They are part of the large group of desert plants called “succulents” which store water in their fleshy leaves to get them through the long dry spells their native climates are known for.
Cacti don’t have conventional leaves, just stems, which are often jointed. They also have “areoles” small holes from which tufts emerge. Sometimes the tufts are soft, like hairs; sometimes they are sharp and spiny. The tufts shelter them from the sun and if sharp, against creatures who might bite them to get at the water inside. The flowers which appear in spring and summer also emerge from the areoles.
Cacti are a large family, with several genera that make good houseplants. Here are some good ones to start with Mammillaria cacti are sometimes called “pincushion” or “nipple” cacti. Most look like small round globes covered with nipples and bear clusters of small, pretty flowers in a crown around the top.
Some good ones to try are the old lady cactus “Mammillaria hahniana” which is well covered with long white hairs, produces red flowers, and generally grows well under 10 inches; the tiny golden star cactus “M. elongata” which is composed of a cluster of long projections with yellow spines and white flowers; M. zeilmanniana, which forms a little round ball and produces pinkish-red flowers even at a young age.
Moreover, the Easter lily cactus (Echinopsis multiplex) is a little round cactus with vertical ribs and large, pink flowers borne on tall stems; these open in the evening and have a lovely fragrance.
Hybrids, which are crossed with species of Lobivia cactus, come in other colors such as red and orange and maybe day blooming. Among the many other good flowering cacti to try are species of Opuntia “prickly pear” Aporocactus “rattail”, Echinocereus “hedgehog”, Ferocactus “barrel”, and Rebutia “crown”.
One of the most popular cacti is the Christmas cactus “Schlumbergera truncate or Zygocactus truncatus” a jungle epiphyte that sends out long, arching jointed stems. Lovely red or white tube-shaped flowers dangle from the tips around Christmas time. The variety is known as the “Thanksgiving cactus” blooms a few weeks earlier and can be distinguished by the fact that the last joint on a stem has two prominent teeth.
A similar plant, Easter cactus (Rhipsalidopsis gaertneri), is spring blooming. Plants are long-lived and can grow as tall as 3 feet and at least as wide. Most cacti prefer full sun, so give them as much of it as you can. Some will do all right in bright light or under fluorescent lights.
They like warm temperatures during the day but can tolerate 40 to 45 degrees at night don’t let them freeze though and may even bloom better if you turn down your thermostat at night. They like dry air but will take average humidity.
In spring and summer when growth is active they should be watered thoroughly. However, during the winter they go dormant for a time, a period they need in order to bloom. They perhaps won’t need water at all during this time unless they wrinkle. If your water is softened water them with bottled water, since they cannot tolerate salt.
Moreover, plant cacti in small, shallow clay pots, with a light, sandy soil except for Christmas cacti. Repot in spring if you see roots in the drainage hole. Don’t feed new plants for a year, then feed about once a month during the growing season with a weak concentration of low nitrogen liquid fertilizer; don’t feed cacti at all while they are dormant.
They love to be summered outdoors, in fact, the cooler days and shorter nights at the end of summer can help to trigger bloom, but bring them indoors when temperatures start to get down into the 40s. Propagate them by transplanting offsets that have developed their own roots.
Christmas and Thanksgiving cacti need more water and fertilizer than other cacti, and they need more organic soil. Feed them twice a month in spring and summer, and let the soil dry out a bit between watering. But starting eight weeks before the time you want them to bloom, give them a rest.
Keep them in a cool place that gets no light at night 50 to 60 degrees, give them no fertilizer and just enough water to keep them from wrinkling, and don’t re-pot them during this time do it in spring. Gradually introduce them to warmer temperatures. Water while blooming, and then keep the cacti on the dry side until spring. They are propagated easily by stem cuttings.
