Echinomastus johnsonii care
Re: Echinomastus johnsonii care
I have new growth coming now, but it really didn't fatten up a lot in spring.

Re: Echinomastus johnsonii care
I have purchased a number of Echinomastus johnsonii and used a potting mix of 1/3 sandy loam, 1/3 pea gravel and 1/3 coarse sand. The cactus have a number of seed pods and will try to harvest seed. I was told that you can water the cactus twice a month or more if the soil dries out quickly. I live in Los Angeles and it rains in the winter months and sometimes in the summer. I know that I do not have high summer temperature and wonder how well these cactus will grow in my area.
What are your recommendations for growing this cactus in Los Angeles?

Re: Echinomastus johnsonii care
I was told that you should never use any pumice when you grow Echinomastus johnsonii because it holds too much water. I was also told to use diluted plant fertilizer twice a year. A number of cactus have finished flowering and green seed pods are forming. I grow the cactus outside and it rained yesterday and today in Los Angeles. I hope that these cactus will grow in Los Angeles. I also see some growth in my Ferocactus cylindraceus that was purchased from the same grower. I realize that I do not have high summer temperatures where most cactus grow but, I have grown cactus for more than fifty years and still have these cactus.
Re: Echinomastus johnsonii care
I do use a little bit of pumice in the potting mix, it holds water but that is a problem only if you water too much or if you let the plants take to much rain. These plants grow from late winter to mid spring, watering beyond that is a risk. From mid may to early october my johnsonii can take water once every 2 or 3 weeks, if temperatures are too high I don't.
Some of the plants in a mix of lapillus, pumice and marl, in full growth as of April 2017 in Rome, Italy good growing

Re: Echinomastus johnsonii care
I planted about 100 seeds recently and will see if any of them germinate. I was told by a grower that he gets between 10-20% germination rate. I wanted to see if I could grow plants from seeds that I collected from my own plants. I have collected more than 1,000 seeds from my plants.

Re: Echinomastus johnsonii care
The seeds are beginning to sprout and will see how many plants will grow. I see one of the seedlings is growing very rapidly and believe that these plants grow in very arid conditions.

Re: Echinomastus johnsonii care
The Echinomastus johnsonii seedlings did not survive the winter months. I am thinking about sowing some more seeds. I had only two adult plants flower and lost two plants earlier this year. A majority of plants are producing new spines. I grow the plants outdoors and receive winter rain with very little summer rain. I have decided to water the plants once or twice a month except for in the summer months when the plants become dormant.
Re: Echinomastus johnsonii care
Don't forget water retention in potting soils is also influenced by climate. If you live in a country with baking hot sun all day you can use water retentive mixes that would quickly cause rot in colder more humid countries. Not only does your soil mix need to be tailored for the containers you use, but also for your climate. When it comes to potting soils recipes there is no one mix that fits all, you need to use them as a starting point, then tailor them to suit your conditions.

Re: Echinomastus johnsonii care
I am continuing to water my plants and many of them are growing new spines. I will stop watering in the summer months.

Hello everyone,
I'm resurrecting this old thread because it's of particular interest to me. I'm really interested in growing cacti from my home state of California, and E. johnsonii is a favorite of mine to encounter in habitat. Does anyone have any idea where I could get seeds from this lovely species?
Thanks a bunch,
ZP

AKA Sclerocactus johnsonii. I usually try eBay first -- unfortunately no johnsonii, but you can find S. wrightii seeds here:zpeckler wrote: ↑Wed Mar 22, 2023 12:48 am Hello everyone,

Re: Echinomastus johnsonii care
I have a single E. johnsonii. Does anyone know if they are self-compatible? If so, I may be able to get you some seed later this year. I have not tried selfing it in the past, and it has not simply self-fertilized and created a nice fruit for me to harvest.

Re: Echinomastus johnsonii care
Thanks man!Three Deserts on Etsy or Mesa Garden
I found Three Deserts (Rob Romero's Etsy Shop) and was able to get a small variety of Echinomastus seeds from him, including johnsonii. I've been keeping an eye on Mesa Garden and I haven't seen their seeds come back in stock in almost a year. I was able to get some from the Czech grower Jan Novak as well, but the import permitting process was a real pain.
The seeds just got planted. Wish me luck!
