Ideal conditions

Due to its light demands, Oreocereus Trollii should be kept outdoors, though it can also thrive indoors if provided with direct sunlight.
The Oreocereus Trollii cactus can survive in quite a wide range of temperatures. These cacti mostly do alright at temperatures as low as 20 degrees Fahrenheit (-6.7 degrees Celsius), and they are also quite resistant to heat thanks to their hair.

Watering

Water Oreocereus Trollii just like any other succulent – when the soil is dry to the touch. This cactus is drought-resistant and thus doesn’t need much water, though it should be watered regularly for best results.
Avoid overwatering the Oreocereus Trollii cactus-like many other cacti, this cactus is sensitive to standing water and may even develop root rot due to it.
If your area is rainy, then you may not need to water your Oreocereus Trollii manually. Only water the cactus yourself when its soil is dry and no rain is expected.
In the winter months, reduce the water supply to this cactus – Oreocereus Trollii gets dormant and has reduced water needs in winter. You may lightly water it once or twice a month, but be very careful with winter watering since root rot is much easier to trigger in winter than in summer.

Where to plant

Plant Oreocereus Trollii in a fast-draining cactus potting mix to prevent water from accumulating around the cactus’ roots. For added drainage, you may add perlite or pumice in a 1:1 ratio or even more.
If planting the Oreocereus Trollii cactus in a pot, be sure to pick a pot with large drainage holes at the base.
Outdoors is where Oreocereus Trollii does best, so we recommend that you do keep your cactus outside where the plant will have easy access to direct sunlight.
Though the Oreocereus Trollii cactus is pretty resistant to heat, you should move it to a shaded location during heat waves or extreme heat just in case.
If you are planning to keep the Oreocereus Trollii cactus indoors, then make sure to place it on a sunny window sill that receives direct sunlight all day.

General care information

Aside from the above, you’ll also need to occasionally fertilize and repot your Oreocereus Trollii cactus.
Fertilization isn’t required if you’ve just repotted the cactus into fresh soil. Otherwise, dilute a cacti fertilizer into half strength and fertilize the soil once every 4-8 weeks, depending on your mix.
As for repotting, the Oreocereus Trollii cactus grows up to 12 feet tall and around 4 inches wide, so your cactus may require repotting quite a few times throughout its lifetime.
Before repotting, allow the soil to dry. Remove the plant from the soil, inspect its roots, and remove any parts that are rotten or damaged. Then, place the cactus into new soil and don’t water it for around a week to allow it to recover.

Synonyme(s): Sulcorebutia canigueralii, S. tarabucoensis – the status of this genus seems to be unclear.
Family: Cactaceae
Origin: Bolivia



Sulcorebutia rauschii - purple shimmering color
A beautiful variety of a miniature cactus from Bolivia. The plant is extremely attractive both due to its coloration and interesting, velvety surface. Its spherical bodies shimmer green and purple, and its surface is covered with small, black, completely flattened spines, which are another decorative element of this species. Sulcorebutia rauschii rarely grows alone, most often it forms compact, dense clumps with many miniature, spherical shoots, the diameter of which usually does not exceed 5 cm. The long list of advantages of this inconspicuous cactus is completed by flowers - intense in their pink-purple color, with a funnel-shaped shape, appearing in large numbers in late spring. Despite its small size, the accumulation of aesthetic values ​​makes this genre very original.

The values ​​of Sulcorebutii rauschii
extremely effective green-purple coloration
structured surface
dense, colorful clumps growing to the sides
beautiful, intense pink-purple flowers
Requirements of Sulcorebutii rauschii
well-drained coarse-grained soil ensuring quick drainage of excess water
very sparing watering (the plant tolerates excess moisture very poorly)
bright, sunny position with good air circulation
fertilize during the growing season
transplanting rare, every few years
Transplanting succulents
The offered seedlings are produced in a peat substrate, which is not suitable for cultivation due to the high water absorption coefficient. Excess water often leads to root rot and disease development. We recommend transplanting succulents immediately after receiving them into the correct substrate. A special substrate for succulents with carefully selected proportions of ingredients that increase permeability can be found in our offer by clicking here. Especially for you, we have prepared a step-by-step instruction on transplanting succulents. The manual is available here. The best times to transplant succulents are spring and summer. When buying succulents in the fall and winter, it is safer to leave them in the existing substrate, taking care of very economical watering. In the autumn and winter period, succulents growing in such a substrate are watered with a little water once every 4-8 weeks (depending on the temperature). To minimize the risk of overfilling, it is best to use the hand-held water sprayer for watering. The shrinkage of the succulent leaves is a clear indicator for the next watering.

Schlumbergera truncata
Common name(s): Christmas Cactus, Thanksgiving Cactus
Family: Cactaceae
Origin: the wild type is native to Brasil
More infos: from Schlumbergera truncata are white, yellow, red, pink and multicolored cultivars available. The wild type has pink flowers.



Care of the plant Schlumbergera truncata or False Christmas cactus
The genus Schlumbergera, family Cactaceae, comprises 8 species of epiphytic cacti originating in Brazil. Some species are: Schlumbergera truncata, Schlumbergera kautskyi, Schlumbergera russelliana, Schlumbergera opuntioides.

Common names: False Christmas cactus, Thanksgiving Cactus, Crab Cactus, Zygocactus, Lobster cactus, Claw Cactus, Holiday Cactus, Linkleaf, Yoke Cactus, Crab's claw cactus, Easter Cactus.

They are epiphytic cacti with hanging stems formed by flat segments with teeth on the edge. These segments are deep green in color that turn reddish in direct sunlight. The showy flowers are tubular in shape with red, pink, white or orange petals. They bloom during the winter.

They are used as indoor plants in hanging pots or in regular pots to place on furniture or windows.

Schlumbergera truncata needs an outdoor shade exposure (mid-spring to mid-fall). Indoors it needs a bright exposure but without direct sun. The temperature should not be lower than 8 ºC; for them to flourish well, the temperature should be 12-23 ºC.

The soil can be a commercial cactus substrate with 1/3 of leaf mulch. The transplant is done in the first half of spring but they do not support it very well.

Irrigate with lime-free water by sprinkling in spring and summer frequently (every 4 days); When the first flower buds appear, water the soil, preventing the flowers from getting wet (water once a week). During the resting period (the plant adopts a matte tone after flowering) reduce watering a lot and lower the room temperature a little.

Fertilize every 15 days with a mineral cactus fertilizer from the second half of spring to the middle of fall.

They are very resistant plants to the most common pests and diseases.

They are easily propagated from stem cuttings during the second half of spring.

Cereus peruvianus “Monstrosus,” commonly known as the Monstrose Apple Cactus, is a cactus with a branching, tree-like form.
The name Cereus originates in a book by Tabernaemontanus published in 1625 and refers to the candle-like form of species.
This cactus is native to Brazil, Paraguay, Uruguay, and Argentina, as well as the nearby ABC Islands of the Dutch Caribbean.. To Purchase C. repandusThe Cereus (Ser-E-us) cactus grows in humid to subhumid forests on rocky outcroppings.
Reportedly, a C. repandus has grown to a height of 110 feet at the SDM College of Dental Sciences at Dhathard Karnataka, India.
Other common names are Peruvian Apple, Peruvian Torch, Apple Cactus, Column Cactus, Hedge Cactus, and Queen of the Night.
Cereus peruvianusis not an ‘officially recognized’ taxon, but nonetheless is a botanical name that is ‘commonly used’ by many to lump together both taxa.
And moreover, some taxonomist will not differentiate between the two as separate taxa and will call them both Cereus repandus.

‘Monstrose’ or ‘Monstrosus’ are botanical terms used to describe a naturally occurring mutant growth formation.

Cereus repandus and Cereus hildmannianus are very similar in appearance and are often confused with each other.
Cereus peruvianus has been scientifically proven to neutralize harmful electromagnetic waves.
These waves are emitted by the television, telephone, computer.

It is reported that placing the plant in those areas of the house where the electronics are placed is beneficial.The large fruit of this cactus is presently being researched as a significant fruit crop for production in arid climates like Israel. Cereus repandus fruits and stems of are edible. Its wood has been used in making furniture and for firewood. Sliced stems have been used as a soap substitute. It is cultivated as a living fence also

‘Cereus’ is a latin word meaning ‘wax’ or ‘torch’.
This cactus is a shy bloomer but when it does they are small white flowers that give way to orange to red fruit that looks similar to an apple. Hense the name Apple Cactus.
Flowers only open at night however and live for less than 24 hours before closing.
Blooming usually happens from June to September. After blooming, the plant will produce fleshy fruits. When ripe, the fruit opens up exposing an edible pulp.

The fruits, known locally as pitaya, olala are thornless and vary in skin color from violet-red to yellow.
The edible flesh is white and contains small, edible, crunchy seeds. The flesh sweetens as the fruit opens out fully.New plants are normally raised from seeds. But, although these seeds germinate and grow up more quickly than those of most cacti, seed propagation is still a slow process.Cereus peruvianus can also be propagated by means of sections of stem rooted in the standard potting mixture, but this process is often impractical since it involves the virtual destruction of the original plant.The Monstrose Apple Cactus grows best in a hot, sunny site with no shade.Newly purchased or planted cacti can suffer from sunburn if they are not gradually introduced to the higher light intensity.
Cereus peruvianus cacti need acclimation, to the fullest possible sunlight. Since the light coming from a window is one-sided, a columnar plant will tend to lean in that direction and so it is most important to turn such plant frequently.
If possible, get the Cereus peruvianus outdoors during the summer months for fresh air and extra light to improve their color and to help lengthen their spines.

Warm temperatures are usually suitable in spring, summer, and autumn.
For the winter these plants should be moved into a cool position where they can rest.
Cereus peruvianus is hardy down to -6°C (20°F) when planted in soil.
Cereus peruvianus tries to continue growing in low-light of the short-day months will develop an abnormally thin, frail stem.At the beginning of the growth period, apply a dressing of slow release fertilizer and stir it into the surface of the soil in the pot. Fertilizer may be incorporated in potting mixture when repotting.
Cereus peruvianus needs either a peat based or soil based mixture will do well. Plants up to 2-inch may be kept in 3-inch pots, but these cacti are fast growing and may need to be moved into larger pots at least once a year.
Where soil does not offer excellent drainage, adding a fine gravel or crushed granite into the planting site and slightly mounding the planting area encourages water to drain away from the plant’s roots efficiently.
Click To Purchase Cactus Soil
Monstrose Apple Cacti grown indoors or as container specimens require a container with ample drain holes and a well-drained potting medium.
Potting medium formulated specifically for cacti and succulents is commercially available.
Remove every plant from its pot in early spring to see whether the roots are tightly packed. If they are, move the plant into a pot one size larger; otherwise, return it to its current pot, but top-dress it with fresh potting mixture.Monstrose apple cactus can be planted in areas with little to no irrigation such as in desert style landscapes, medians, and hot, arid climates.
Because of its extensive taproot system and relatively no need for regular watering, Cereus peruvianus, like other members of the cactus family, has very low water and fertilizer needs.

Before providing supplemental irrigation, it is a good idea to feel the soil an inch below the soil surface to make sure it is completely dry to the touch.
Cereus peruvianus, when established, generally need watering only once or twice per month.
A light application of a balanced fertilizer in early spring encourages monstrose apple cactus growth but is not necessary. No irrigation or fertilizer applications are necessary from late fall through spring when conditions are cool and wet.In poorly drained soils or if this cactus is subjected to excessive moisture it is likely to end up with root rot. Select a site with good drainage or improve site drainage to avoid this and only water the cactus when it is warranted.
Cereus is only necessary to control plant width as desired and thin outcrossing or unsightly branches.
Pests include scales and mealybugs, which are best addressed by providing the cactus with proper cultural care.
Preventing natural predators or parasites of the pests to achieve control.
Pests include scales and mealybugs, which are best addressed by providing the cactus with proper cultural care and allowing natural predators or parasites of the pests to achieve control.
