Snow covered cacti on the balcony


Snow covered cacti growing in window boxes

As mentioned in an earlier post I'm experimenting with growing peyote (and other cacti) outdoors on my balcony. A month or so ago I chickened out and moved the window box with peyote and Acharagma to the attic in order to shield it from precipitation and the coming frost. Today I'm glad I did as the balcony (and the flower boxes with it) has been completely covered in snow for the last couple of days - and I'm not sure if that would become the peyote plants well.


Echinocereus triglochidiatus covered by snow (with E. reichenbachii in the background)

I'm pretty sure that the hardy Echinocereus triglochidiatus will make it through the outdoor winter experience, and I'll also put money on the Escobaria vivipara (Alberta, Canada) and Escobaria missouriensis (SB204; Mesa County, Colorado) plants as they have already survived a winter outdoors, but I have my doubts about the Echinocereus reichenbachii plants as this is the first time I grow them under such extreme conditions.


Snow covered Mammillaria grahamii

Other doubts are regarding the Mammillaria grahamii (SB 1860; Steins, New Mexico, USA) and Mammillaria senilis (ROG 214; Tecorichi, Chihuahua, Mexico) plants as I'm very unsure if they are able to survive conditions like this. We'll know come spring.

Late-flowering peyote cactus

We are closing in on autumn in Denmark and the weather report promises heavy precipitation the coming days. Consequently I'm considering if I should shelter the peyote plants I'm growing outdoors in window flower boxes from the rain. Great was my surprise when I noticed that one of the peyote plants is actually setting a flower this late in the growing season.


Late-flowering peyote cactus

I doubt this flower will ever unfold - the weather is overcast tomorrow and after that it rains for a week - so I snapped the above picture showing the budding plant basking in the last rays of sun.

... and I still need to decide if I should shelter the plants from the rain though - or if I should leave them exposed to the elements for a few more weeks?

Reclaiming my winter-hardy cactus bed - day 2

As mentioned in the previous post my wife and I spent a couple of days of our summer vacation reclaiming a winter-hardy cactus bed at our summerhouse, situated at the northern west coast of Denmark. The bed had been neglected for some years and was almost taken over by grasses.


Winter-hardy cactus bed - half of which is still overgrown by grasses

At the beginning of the second day we were still missing half of the bed. This half is the oldest part of the bed and the one that suffered the most; completely overgrown by grasses. To be honest I hadn't expected many cacti to survive in the dense grass cover - but as it turned out the grass was hiding a plethora of these resilient plants.


Recovering winter-hardy Opuntia cacti from the dense grass cover

Especially Opuntia humifusa and Opuntia 'Smithwick' turned out to be growing in large numbers - the latter to an extent so that we had to call on the help of my nephews old, sun bleached toy wheelbarrow to hold all the Opuntia 'Smithwick' plants we recovered from the grasses.


Reclaimed winter-hardy cactus bed

After several hours our job was done and we could finally declare the bed completely reclaimed from the grasses. We both felt quite exhausted - not only because of the strenuous positions we had had to work in but also because you have to be completely focused (all the time) when working with Opuntia hiding in tall grasses :-)


Overview of the newly reclaimed part of the Opuntia cactus bed

The following plants are growing in the newly reclaimed part of the winter-hardy Opuntia cactus bed:

Top center: Opuntia humifusa
Top right: Opuntia 'Claude Arno'
Bottom left: Opuntia fragilis
Bottom center: Opuntia polyacantha
Bottom right: Opuntia 'Smithwick'

The plants at the top left are Opuntia trichophora v. nova (Roswell, New Mexico) growing in the part of the bed that was reclaimed the day before.

Reclaiming my winter-hardy cactus bed - day 1

Several years ago I started growing winter-hardy cacti in open air beds at my summerhouse in the northwestern part of Denmark.


Neglected winter-hardy cactus bed almost taken over by grasses

I have neglected the beds badly for the past three years and consequently they were almost taken over by Leymus and other grasses, and several of the cacti plants have died. Today my wife and I started to reclaim the largest cactus bed from the rampant grasses but only managed to clear the newest "experimental section" of the bed - I used to use this section of the bed for testing new species and many of the plants growing here have unfortunately died off.

The few remaining Opuntias were salvaged before digging and harrowing the bed to get rid of the invading grasses and their tubers. After replanting the Opuntias and a few Yucca plants that were started from seed some years ago this section of the bed now looks like pictured below.


Reclaimed and replanted cactus and yucca bed

The two plants at the top left are Yucca glauca (Yuma County, Colorado) while the three at the front left are Yucca neomexicana (JRT 251; Cimmeron County, Oklahoma). The center plant is an Opuntia hystricina cultivar named 'Hanau' and finally the plants at the top right are Opuntia trichophora v. nova (Roswell, New Mexico).

We'll continue salvaging the remaining part of the bed tomorrow.

Peyote plants maimed by birds

As mentioned in the post "Growing peyote (and other cacti) on the balcony" I'm experimenting with growing peyote cacti in window flower boxes on my balcony.


Peyote cactus maimed by a bird

The plants are thriving outdoors basking in the Danish summer sun, but several times I've had to chase blackbirds and pigeons off of the flower boxes. Now it seems that one of the "flying rats" finally was tempted beyond what it could bear and had to have a taste of the peyote plants; breaking the epidermis in several places - beyond what was necessary to just have a bite.


Bird damaged peyote in flower box

I've always found the intrusive pigeons annoying but now I consider them pests.

Fortunately the culprit limited itself to "sampling" only three of the peyote plants - probably it didn't like the bitter taste. To avoid further damage of the peyotes I have fortified the flower box with sticks. Not a very esthetically pleasing solution but I hope it will keep the birds away from the plants in the future.

Mummified aphids - an aphid parasitoid at play


Acyrthosiphon pisum (pea aphid) - courtesy of Wikipedia

Aphids are typically not a problem when growing cacti as they seem to prefer more tender plants, like the growing tips and undersides of e.g. Capsicum plants (a.k.a. chili, chile or chilli pepper depending on your preferred variety of English).

Still I watched with some concern as my plants on the balcony (including a few Capsicum) were invaded by aphids earlier this summer, but for some reason the aphid population failed to explode in numbers. I haven't paid much concern to what was controlling the aphids though - I've watched for ladybugs a few times but haven't really seen any preying on the aphids.


The "mummified" remains of an aphid

Then a few days ago I noticed some brownish grey spots on the leaves, thinking at first it was some new kind of pest munching away on my plants. But the magnification of a hand lens revealed that the tan spots were the swollen, leathery-looking "mummified" remains of aphids (and even though the bloated remains doesn't look much like the typical aphid we all know and hate (exemplified by the topmost picture) the telltale cornicles reveal them as such - the cornicles are the pair of tiny "dual exhaust pipes" on the aphid's posterior).

Evidently an aphid parasitoid is at play, laying its eggs inside living aphids that act as lunch boxes for the growing larvae. Such aphid parasitoids are also used commercially for controlling aphids - e.g. Aphidius matricariae are released in many greenhouses.


Larva growing inside immobilized aphid

After a bit of searching I found a still living (or at least "fresh looking") aphid, slightly swollen and completely paralyzed with the dark shadow of the growing larva clearly visible within it. Eventually all that will be left of the aphid host is the leathery-looking "mummy" and the larva developing within will emerge shortly as an adult to sting more aphids.

It's brutal but I side with the aphid parasitoid :-)

Tricotyledon Echinocactus polycephalus seedling


Tricotyledon Echinocactus polycephalus seedling

As mentioned in the previous post I started a handful of Echinocactus polycephalus (SNL 91; Las Vegas, Nevada) from seed a few weeks ago. I didn't achieve impressive germination rates and many of the seedlings were killed off by mold while still enclosed in the humid atmosphere of the germination "tent" - and more have withered after I exposed the seedlings to the harsher environment outside of the plastic bag they germinated in. So for all practical purposes Echinocactus polycephalus (and E. horizonthalonius) live up to their reputation of being extremely difficult to grow from seed.


Echinocactus polycephalus seedling growing its first spines

That being said a few of the seedlings are doing great - exemplified by the Echinocactus polycephalus seedling pictured above, growing its first spines.


Tricotyledon Echinocactus polycephalus seedling - top view

Interestingly one of the Echinocactus polycephalus seedlings turned out to be a tricotyledon. Members of the Cactus family belong to the group of dicotyledons, i.e. their seedlings have two cotyledons or embryonic leaves. So evidently Echinocactus polycephalus is a dicot but for some reason this seedling decided to grow three seed leaves instead of the habitual two.

Polycotyledons could be considered freaks of nature or "mutant" plants but this seedling will probably grow up looking exactly like the other plants from the same batch. The last time I experienced a polycot seedling was some years ago when an Opuntia polyacantha var. hystricina seedling germinated with three seed leaves.

Tricotyledon Opuntia polyacantha var. hystricina seedling

Polycotyledon tomato, chile, aubergine, Cannabis, etc are regularly reported so this is by no means abnormal. It would be interesting to know though if this is affecting the plants in any way (as mentioned, the last time I experienced a tricot seedling the plant grew up to be indistinguishable from the "normal" plants). I'm also curious as to what is causing the extra seed leaves (the Opuntia seedling mentioned above was grown fresh from seed collected in the Grand Canyon; indicating to me that polycots are occurring naturally and are not (only) caused by "mutagens" in the environment).

Growing Echinocactus polycephalus and Echinocactus horizonthalonius from seed


Immaculate Echinocactus polycephalus seedling

Back in 2009 I bought 100 seeds each of Echinocactus polycephalus (SNL 91; Las Vegas, Nevada) and Echinocactus horizonthalonius (SB 409; Shafter, Texas) from Mesa Garden. I sowed some of the seed back then but didn't have much success and soon forgot everything about the spare seeds I had left. That is until a few days ago :-)

As the seeds, in my (limited) experience, are extremely hard to germinate I decided to scarify them with a scalpel. You have to be very careful not to damage the embryo when making shallow cuts in the testa (seed coat) with a scalpel - and manually scarifying 80-some tiny seeds is an extreme test of your patience. After brutally cleaving several seed embryos I settled for chipping away at the protrusion of the hilum - this allowed me to break of small pieces of the testa without damaging the embryo within. The scarified seeds were left to soak in water for a few hours - I added the smallest tad of detergent to remove the water surface tension and allow for more efficient soaking of the seeds.


Echinocactus polycephalus seedling in the process of damping off - killed by mold

A few days after sowing the seeds several seedlings have surfaced. Unfortunately a few of them are already showing "rusty" spots and some has completely damped off, killed by mold. Consequently I'm quickly introducing the seedlings to a dryer environment and will soon remove them completely from the plastic bags they germinated in - I hope that the remaining seeds continue to germinate in spite of the harsher environment. Steve Brack's encouraging notes regarding this type of cacti reads: "rot easily, right after germination: not too wet, dry air and stronger light."


Etiolated Echinocactus polycephalus seedling, red from the sun

Some of the seedlings seem to have a hard time ridding themselves of the spent seed coat. They grow slightly etiolated and don't develop much chlorophyl in the deep shade of the testa - consequently they turn all red when exposed to the sunlight.


Echinocactus polycephalus seedling showing "rusty" spots

As usual I'm germinating my seeds in pots placed in clear plastic bags. As it's early summer I'm experimenting with germinating the seeds outdoors on the balcony - the daytime temperatures are around 20 C (68 F) with pleasantly cool nights. The temperature inside the bags off course grow hotter as they are exposed to sun during the day.


Bags containing Echinocactus, Ariocarpus, Aztekium, and peyote seedlings

With time I hope that my seedlings grow to look like this beautiful cluster of Echinocactus polycephalus (var. xeranthemoides) that overlooks the Tonto Platform in the Grand Canyon


Echinocactus polycephalus (var. xeranthemoides) overlooking the Tonto Platform

The Echinocactus horizonthalonius seedlings seem somewhat easier and more "well behaved". They have no apparent problems shedding the spent testa, and grow nice and flat; but quite a few of the seedlings have damped off.

Growing peyote (and other cacti) on the balcony


40 peyote cacti growing in a window flower box

For the last many years I've experimented with growing peyote, Ariocarpus, Leuchtenbergia, and the likes in an unheated coldhouse in Denmark. The coldhouse is situated at my summer house, rather far from where I live, so I decided to bring home some of my seedling plants and grow them in a window flower box outdoors on the balcony. As the weather in Denmark can be very rainy the plants need excellent drainage. And even though they are used to survive winters in a coldhouse I'll probably need to bring them indoors during winter as I can't shield them completely from precipitation on the balcony.


Flower box planted with peyote and Acharagma

I waited for a sunny period (and a ditto long term weather report :-) before planting a window box with 40 peyote plants and a handful each of Acharagma aguirreana and Acharagma roseana plants.

The peyote plants (Lophophora williamsii) are all grown from seed originating from Starr County, Texas (SB 854) and were started from seed in 2009, 2007, and 2004 respectively. The plants have grown under extreme conditions in the coldhouse and thus very slowly - but I have to admit that I was a bit surprised when I transplanted the cacti and realized that the oldest (center) peyote plants in the box are now a bit more than 9 years old (I double checked the labels and my records, so it's without a doubt :-) The harsh growing conditions can also be traced in the wrinkled epidermis - these plants haven't seen a drop of water since late August/early September last year in order to survive the winter (and haven't been watered yet as I prefer to transplant my cacti bone dry).

Both Acharagma species were started from seed in spring 2009.


Drainage layer of Leca pebbles

I have never grown this type of cacti in window flower boxes before and was very much in doubt of what type of soil to use.

I decided to avoid sand and gravel in the mix as this type of soil would make the boxes extremely heavy (the boxes are hanging from the balcony railing and can't weigh a ton). Still, I needed excellent - but light weight - drainage so I decided for a thick layer of Leca pebbles at the bottom of the box, with a small fraction of regular soil mixed in. Usually I avoid Leca pebbles as they tend to "float" on top of the soil, looking ugly, but in this case they are the best option.

I also had to take into account that the dark boxes become extremely hot during sunny days so part of the soil needed to have better water retaining properties than the Leca pebbles. My solution was to use a top layer consisting of burnt moler cat litter and coir (a natural fibre extracted from the husk of coconut) - both are able to retain water but don't get soggy and waterlogged.

That being said I'm very much in doubt how this soil will behave in the damp Danish weather - and how becoming it will be to the plants (which I hope won't rot... but I'm sure time will tell :-)


Flower box planted with Echinocereus reichenbachii and Mammillaria

Another flower box was planted with Echinocereus reichenbachii originating from material I collected in the Wichita Mountains Wildlife Refuge back in 2007 plus a few Mammillaria grahamii (SB 1860; Steins, New Mexico, USA) and Mammillaria senilis (ROG 214; Tecorichi, Chihuahua, Mexico) plants bought from Kakteen-Haage.

I don't have much experience with growing Mammillaria species but selected these plants for their ability to tolerate cold conditions - and also for their beautiful flowers of course :-) One thing I learnt the hard way is that the fish hook spines of the Mammillaria plants behave like velcro when the plants get too close to each other, i.e. you should be very careful when planting several plants in the same container.


Three cacti window flower boxes on a row

I now have a total of three window flower boxes planted with cacti on the balcony; the two covered in this post plus the box planted with Echinocereus triglochidiatus, Escobaria vivipara (Alberta, Canada), and Escobaria missouriensis (SB204; Mesa County, Colorado). The latter box was planted last year and wintered outdoors on the balcony.

Sunburned San Pedro cactus (Trichocereus pachanoi)

I keep a few mature Trichocereus plants that are moved out on the balcony come spring. While the Trichocereus peruvianus (Peruvian Torch cactus) and Trichocereus bridgesii plants usually take the transition to being exposed to the elements in stride, I always have to look out for my Trichocereus pachanoi (San Pedro cactus) not to get sunburned. Like in humans sunburn in cacti is the result of an inflammation/damage of the epidermis caused by excessive exposure to ultraviolet (UV) radiation from sunlight; typically most severe in new growth.


San Pedro cactus developing a sunburn

Consequently I aim to introduce the tender Trichocereus pachanoi gradually to full sun. This spring I made sure to place the San Pedro in an area that lies in shade most of the day. I even heeded the weather reports and moved the plants indoors on sunny days. Still the San Pedro is developing a sunburn in the new growth area facing the sun - interestingly it doesn't seem to get sunburned at the growing point at the tip but always a bit down the side from it, probably because of the steeper angle of incidence of the sun rays and UV radiation.


Undamaged, bright green new San Pedro growth

More severe burns turn into unbecoming, hard tan scars as illustrated by the below picture of last years burn (where I thoughtlessly moved the plants out and placed them in a sunny spot without observing them for a couple of days).

A light sunburn can be outgrown but the hard scars are permanent.

I'll end this post on a more positive note with the image below of a Ginkgo biloba happily setting new leaves :-) The Ginkgo biloba grows on the balcony year-round.
