Stems, Blooms,
and Fruit
The large fruit of this cactus is presently being researched as a significant fruit crop for production in arid climates like Israel.
Cereus
‘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.
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.
Propagating Cereus peruvianus
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.

Light and Temperature Requirements
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.

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.

Soil and Site Considerations
Cacti grow best in a well-drained sandy or gravelly loam soil, in general.
At the beginning of the
Cereus
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.
Monstrose Apple Cacti
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.
Water and Fertilizer
Cereusperuvianus is a very fast grower. This plant is a perfect candidate indoor plant for a sunny south, east or west window.
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
Supply a deep watering about four to six weeks following planting.
The plant will need supplemental water about every two weeks during the first hot summer following planting to
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.

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.
Potential Problems or Pests
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 peruvianuspruning 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.

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.
On young or very visible specimens, knocking mealybugs off the cactus with a forceful stream of water or applying insecticidal soap or horticultural oil is warranted. Or check out The Perfect Solution For Healthy Plants.
