ABOUT:

Cereus forbesii ‘Spiralis’ Cactus is a fast growing columnar and then later branching cactus that over time forms into a ‘Candelabra effect’ from the base.

When young and grown from seed these cacti start off growing straight and then start to grow with a twist after 5 cm’s in height and can reach 13 feet high when mature.

Cereus forbesii ‘Spiralis’ originated from an original cactus in Brazil and around 1980 a few cuttings from this original cactus were taken and imported into Europe. Nearly all Cereus forbesii ‘Spiralis’ that are sold worldwide have been grown from seed or from cuttings.

This cactus is becoming more common in cultivation with many online and garden shops selling it.

Here is a special Video I have made for my You Tube Channel called Desert Plants of Avalon on How to Care for & Grow Cereus forbesii ‘spiralis’ Cactus, and you can watch this video below:

LIGHT REQUIREMENTS

Mature Cereus forbesii ‘spiralis’ like full sun, and a sunny position or window or greenhouse is ideal, but young plants like to have more shade until they are more mature.  If you are growing these Cacti behind glass though you will need to protect them from intense midday sun on very hot days in Summer, this is to prevent scorch or yellowing of the cactus skin, and a shade cloth or light net curtain can be used over glass to protect these cacti from the very hot midday sun in Summer. If you only have a north facing window that never receives any sun or growing indoors away from windows then LED Plant Grow lights especially made for plants can be used to replicate the natural full spectrum light and sunlight that these cacti need to grow and thrive.

SOIL

Cereus forbseii ‘Spiralis’ need a very well draining cactus and succulent soil that is free draining and dries out fast in between watering’s, you can use any good quality cactus soil that is ideally low in peat, but I like to make up my own Cactus soil of 3 equal parts of Loam, Grit and Horticultural sharp Sand, you can also use Pumice or Perlite or Lava Rock instead of Grit, the most important thing to remember is that the soil drains fast and dries out fast in between watering.

Here is a video I have made for my You Tube Channel called Desert Plants of Avalon on How to make Cactus Soil in 3 easy steps: 

WATERING

Spring and Summer water when the soil in the pot has dried out and reduce watering from late Summer, keep Cereus forbesii ‘Spiralis’ cacti dry with little to no water over the Winter months, If your cactus starts to look shrivelled over the Winter months then a light watering can be given as long as the temperature you are overwintering your Cactus is above 10 Celsius /50 Fahrenheit, as temperatures lower than this can cause rot. 

FERTILISING 

Feed Cereus forbesii ‘Spiralis’ Cacti twice a month in Spring and Summer with a good quality cactus and succulent fertiliser, you can also use a good quality Tomato feed used at half the recommended strength that they recommend for tomatoes, if you want to see what I like to use to fertilise my cacti and how I do it then check out this video I made for my You Tube Channel called Desert Plants of Avalon on How I fertilise my Cacti and you can watch this video below:

TEMPERATURE

These Cacti like a minimum Winter temperature of 50 Fahrenheit / 10 Celsius and they are not frost hardy at all. The ideal temperature during their growing season in Spring and Summer is around 60 – 80 Fahrenheit / 15 – 27 Celsius, its best to protect these cacti from excess heat above 85 Fahrenheit / 30 Celsius because stems can scar and scab and yellowing can occur unless plenty of ventilation can be given, open windows and use circulating fans in very hot sunny weather.

RE POTTING 

Re potting is best done in Spring and Summer and when the cactus has outgrown its pot. Cereus forbesii ‘Spiralis’ grow fast when they are given plenty of root space and you may need to re pot every one to two years. Once repotted its best to keep these cacti unwatered for a week to ten days to allow the roots to settle into the new soil and pot.

If you want to know How to repot a cereus forbesii spiralis cactus than check out this video I made for my You Tube Channel called Desert Plants of Avalon on Repotting a Cereus forbesii spiralis Cactus and you can watch this video below:

FLOWERING

Cereus forbesii ‘Spiralis’ will produce White and pink blooms in Summer with buds a deep purple colour, red fruits form if the flowers get pollinated.

If you want to know How to get your Cacti to flower, then check out this video I have made for my You Tube Channel called Desert Plants of Avalon on How to get your Cacti to Flower and you can watch this video below: 

PROPAGATION 

Cereus forbesii ‘Spiralis’ can be propagated by seeds or from cuttings taken in Spring or Summer, Cuttings must be allowed to fully callus over for a few days or weeks first before planting. These cacti grow tall and branch out over time and these branches can be pruned off and taken as cuttings. Seeds will germinate after 2-6 weeks. If you want to know How to Grow Cacti from Seed then check out a video I have made for my You Tube Channel called Desert Plants of Avalon on How to grow Cacti from Seed and you can watch this video below:

PESTS 

Mealy Bugs and Spider Mites, Thrips and Scale insect are the most common pests of all cacti, but Cereus forbesii ‘spiralis’ is very prone to Mealy Bugs and Scale insects, this is because these pests love to hide in between the twists on these cacti. Remove any pests that are visible with a q tip cotton bud dipped in rubbing alcohol / Isopropyl alcohol, and then once pests have been removed with the rubbing/isopropyl alcohol treat the whole cactus with a systematic insecticide spray or Horticultural Neem oil mixed with Horticultural soap.  Check out a video I have made for my You Tube Channel called Desert Plants of Avalon on How to use Neem oil on Cacti as a pest and disease treatment, and you can watch this video below:

How To Care for Myrtillocactus geometrizans ‘Fukurokuryuzinboku’ The Booby Cactus

Hi Guys 😀 In this Cactus care Blog I am talking about the very unusual and very wacky and yes a little bit naughty of a cactus called Myrtillocactus geometrizans var. ‘Fukurokuryuzinboku’ also known as ‘The Booby Cactus’ 

I have made a special How To Care for video on Myrtillocactus geometrizans var. ‘Fukurokuryuzinboku‘ also known as ‘The Booby Cactus’ on my You Tube Channel called Desert Plants of Avalon and I have linked the care video at the end of this Blog 😀 

Myrtillocactus geometrizans cv. Fukurokuryuzinboku, Myrtillocactus geometrizans
Myrtillocactus geometrizans, Myrtillocactus geometrizans cv. Fukurokuryuzinboku, also known as Blue Candle Booby cactus, Breast Cactus, Titty Cactus.

ABOUT :

Myrtillocactus geometrizans Fukurokuryuzinboku is a monstrose cultivar of the more commonly seen Myrtillocactus geometrizans, but this Cactus has more unusual shaped ribs along with areoles that resemble nipples making this cactus appear like it has little breasts in appearance, this is why this cactus is often nicknamed as ‘The Booby Cactus’ or ‘Titty Cactus’.

Myrtillocactus geometrizans Fukurokuryuzinboku is a rare plant to find for sale and is only available from specialist cactus nurseries and online cactus nurseries but is now becoming more popular to grow in cultivation, it is definitely one of the more expensive cactus plants to buy.

It is a Japanese cultivar that can grow up to 4.5 metres high ( 178 inches ) and 10 cm wide in diameter ( 4 inches ).

LIGHT :

This cactus definitely like a nice sunny spot, however when these plants are still young ( less than 3 inches in height ) or if taken as cuttings they are best placed in a less sunnier position, however when cuttings have fully rooted and the plant is taller than 3 inches in height they love to be placed in a sunny position as long as ventilation can be provided. If grown on a very sunny south facing window in the middle of summer then a shade cloth may be placed over the window to allow indirect sunshine onto the plant this will prevent scorch or yellowing of the stem.

SOIL : 

A very well draining cactus soil is an absolute must for these cacti as soil that stays wet for too long will encourage rot, a good quality well draining cactus and succulent soil mix is to be used and not any other type of houseplant soil. I like to make my own cactus soil up for these cacti and use a mix of 3 equal parts of Loam, Horticultural sharp sand, and Grit. Here is a video I have made for my You Tube Channel called Desert Plants of Avalon on How I make my own cactus soil and you can watch this video below:

WATERING : 

From Spring until mid Fall / Autumn these cacti love to be watered very regularly always allowing the soil in their pots to fully dry out first before watering them again, this is a better guide I like to give to people because when it comes to watering all cacti, one size does not fit all haha, as it can depend on many different factors for example the temperature, the climate etc, but as a good rule of thumb during their active growing period of Spring until mid Fall I recommend to water every time the soil in their pots has fully dried out.

In Winter these cacti like to have a winter rest period and no water should be given from late Fall / Autumn  until Spring. Its normal for these cacti to shrivel as they use up their water stores during winter and their little ‘breasts’ will start to shrivel haha ‘however if you are overwintering your cactus indoors in a heated room and notice that the cactus is looking a bit too shrivelled you can go ahead and water just enough to plump up the plant again, but avoid doing this if growing your cactus in a cooler environment e.g a greenhouse or polytunnel etc, due to the cooler temperatures and higher air humidity levels of a greenhouse or polytunnel or other outdoor structure, its better a few wrinkly ‘boobs’ than  rotten ones haha, and your cactus will soon plump back up again in Spring when normal watering resumes.

Clean Rainwater is always best if you have access to it, but if not then let your tap water sit for 24 hours to help to dissipate some of the chemicals that are present in tap water.

FERTILISING : 

From spring and Summer feed these cacti once every 3 weeks with a good quality cactus and succulent fertiliser. Do not feed at all in Winter when these plants are resting.

TEMPERATURE : 

Myrtillocactus geometrizans Fukurokuryuzinboku can not take frost and in Winter this cactus must be kept above 10 Celsius / 50 Fahrenheit, many growers would recommend that they can take lower than this if kept totally dry over winter but personally I would not recommend it as Myrtillocactus has a tendency to scar and scab and at the worst case rot in low temperatures during the Winter months when they are dormant, especially in my climate in Ireland and the UK where the air humidity is very high outdoors in winter, if you live in a more arid winter environment and country then its possible these plants can take lower temps in Winter but avoid frost at all costs.

During the Spring and Summer these cacti can take very high temperatures as long as plenty of ventilation can be given. If growing behind glass, e.g in a sunny window or greenhouse or conservatory, sun room etc, then windows must be open or and a fan / doors etc for ventilation during very hot and sunny days.

RE POTTING : 

Its best to re pot these cacti during their active growing period in Spring and Summer and only when the plant has outgrown its pot, as with all cacti its far better to under pot rather than over pot because too much soil around their roots can stay damp for too long and may encourage the chances of root rot.

FLOWERING : 

Myrtillocactus geometrizans Fukurokuryuzinboku will bloom when mature from about 60 cm tall in height ( 24 inches ) The flowers form in Spring and are small white flowers.

PROPAGATION : 

Propagation of Myrtillocactus geometrizans Fukurokuryuzinboku is from cuttings taken in Spring and Summer. Cuttings need to fully dry ( callus ) over for a couple of weeks or more until a hard white callus has formed at the base of the cut before planting up as cuttings. Cuttings of these cacti need very warm weather above 18 Celsius / 65 Fahrenheit to root for the best success, additional heat with a heat mat can help with rooting these cuttings if your Summers are cool and damp like mine in Ireland and UK.

Seed propagation of Myrtillocactus geometrizans Fukurokuryuzinbokus is not recommend, this is because this cactus is a monstrose variety of the original Myrtillocactus geometrizans and any seeds germinated will grow as normal Myrtillocactus geometrizans cactus plants and will not grow with the little ‘breasts’.
