Winter Tips (primarily)

Linda Gamble provided this compendium of information from various reference sources on the internet (like cactuslimon.com).  The information listed is valuableAs time permits, the list can be extended and amended.  Temperature maximums and minimums would be great additions along with members' personal success tips.  When striking out to grow your plants here in Southern Nevada, remember how hot and scorching the sun can be, how cold that dark corner of your north patio can get, and most of all:  if what you are doing "isn't broken, don't fix it."

SUCCULENT PLANTS

 

Adenium Plant Care:  Good for beginners. Likes light and some summer sun; ideal winter plant for indoors.  It doesn't mind dry warm air. The more it is in the sun the more abundantly it blooms, if in winter it remains in a warm room it continues to grow; when the plant is on a window sill, it should be turned regularly, otherwise it only grows in one direction. In the summer, when it is actively growing, water more, but make sure the soil drains well.  In the winter if the plant goes nearly dormant, water less.  From March to September fertilize every 3 weeks with cactus fertilizer.  (If the caudex becomes soft, the plant has likely been overwatered for the given light conditions.  Severe underwater can also cause a softening of the caudex.)

 

Adromiscus Plant Care:  They like sunny warm, light location. In the summer water abundantly, provide good drainage to avoid wet soil, in the winter hardly at all. Propagate with leaves that have fallen.

 

Aeonium Plant Care:  The plant likes to be in a light location in the summer in half shade and plenty of water, in winter they require bright and cool situation. If potted put the plant in a pot that is too large, rather than too small.

Aloe Plant Care: Sunny location, light shade, moderate water in summer, opinion is divided as to weather aloes should receive any water in winter, a little water will help prevent die back of the leaf tips, to much will result in loss of roots by rooting. When potting aloes the stem must not be buried. Some turn red in the bright sun and they will turn green again if they are in the shade.

 

Aloinopsis Plant Care:  This succulent needs a very open soil, it is not necessary to repot annually, it is better to break the cluster up, pull the heads off, dry for two days then pot . Water the plant freely but small amounts during summer, allowing to dry between watering, do not water during winter.

 

Avonia Plant Care: locate in a very sunny and warm spot; water very little; use a very porous cacti soil with good drainage.

Provide proper drainage and considerably less water in the cool months. Do not let this specimen sit damp in cool weather, they need good draining soil.

 

Pleiospilos bolusii:  They are stone-like plants (sometimes called living stones). The surfaces are grayish -green covered with dark dots, resembling a small chunk of granite. The plant consists of one pair of very succulent leaves with flattened tops; the leaves are about 1" long and almost as broad. The stem is so short that the plant is almost described as stem less. The heads may be split off in late summer to propagate the plant. It flowers in autumn; the flower opens in the late afternoon, but only on sunny days, they are golden yellow. When the previous season's leaves have completely shriveled, the current season leaves will be well formed, this will be late summer. This species grows large.
