Read More... Cultivation and Propagation: Rebutia vulpinaSN|5039]]SN|5039]] is easy to grow and free flowering. Nevertheless, it is appropriate to provide adequate growing conditions in order to obtain abundant blooms.
Growth rate: It is a relatively rapidly growing species that will make large clumps given the best conditions.
Soils: As most Rebutia cultivated for their blossom, it needs a soil mixture a little richer than the average cactus with still an excellent drainage. Prefer a low pH compost, avoid substrata too rich in limestone.
Repotting: This plant needs plenty of space for its roots, repotting should be done every other year or when the it has outgrown its pot. It is rot prone and should be planted in a shallow pot. Use pot with good drainage.
Watering: Needs moderate to copious waterings in summer (it is more demanding than other cactus), but do not overwater, keep dry in winter at a minimum temperature of 0°C.
Fertilization: Feed with a high potassium fertilizer in summer.
Hardiness: It is quite frost resistant if kept dry and hardy to -5° C to -18° C for short periods (depending on varieties and growing conditions). However warmth throughout the year will increase the grower's success (minimum 5° C during rest season).
Exposition: The plant tolerates bright situations which encourages flowering and heavy spine production, but is likely to suffer from sun scorch or stunted growth if over exposed to direct sunlight during the hottest part of the day in summer. It grows well with filtered sunlight or afternoon shade.
Uses: It is an excellent plant for container growing. It look fine in a cold greenhouse and frame or outdoor in a rockery. It is also used as a rootstock for grafting delicate and slow growing cactus species.
Pests & diseases: It may be attractive to a variety of insects, but plants in good condition should be nearly pest-free, particularly if they are grown in a mineral potting-mix, with good exposure and ventilation. Nonetheless, there are several pests to watch for:
- Red spiders: Red spiders may be effectively rubbed up by watering the plants from above.
- Mealy bugs: Mealy bugs occasionally develop aerial into the new growth among the wool with disfiguring results, but the worst types develop underground on the roots and are invisible except by their effects.
- Scales: Scales are rarely a problem.
- Rot: This species is particularly easy and accommodating, seldom suffer of cryptogamic diseases. Rot it is only a minor problem with cacti if the plants are watered and “aired” correctly.
Propagation: Direct sow after last frost, offsets (if available) . Seeds germinate in 7-14 days at 21-27° C in spring, remove gradually the glass cover as soon the plants will be well rooted (ca 1-2 weeks) and keep ventilated, no full sun for young plants! To make a cutting twist off a branch and permit it to dry out a couple of weeks, lay it on the soil and insert the stem end partially into the soil. Try to keep the cutting somewhat upright so that the roots are able to grow downward.
