I have 3 to ID. All are out side in the garden.

I have not done pictures of before and after , but I do notice when I put a nursery grown/greenhouse cactus into my garden by the end of the first season it will shrink up to or more than 50% or the transplanted size. I have seen this with Echinocereus, Mammillaria, Echinopsis, even Echinocactus. I ...

The outside garden blooming are mostly Echinopsis oxygona and Paramount green gold and in the background a E. Epic. The original plant I received some 20 years ago and lives through the cold wet winters, when it rains, and the 100+ degrees in summer. I planted them, they survived and as a bonus, flo...

Not often, but some days you're home to see the one day show and not have to work, or take a sick day.

Maybe a Ferocactus gracilis

To answer your questions more info would help. Size would help, budget, material you can use in your area. I have built and bought greenhouses and I find what I was looking for the in the greenhouse lead me to each one. I was able to buy redwood so I built, needed to add on, so I bought a Harbor Fre...

Don't water? Your plant may not need any water until April. Depends upon you location and how you are growing your plant i.e., greenhouse. From what I see, your plant looks fine, not sure about the white specks.

Winter bloomer.

You're 2 plus hours north of me and I have had an outdoor garden 20 plus years. Tracy may not get as cold as here, but you should get more rain. I cover the growth points on some plants that can't take the cold as much and most have no issues. I have a Ferocactus that had standing water in the growt...

Did you grow them from seed or did you just buy that many of them when you went to the cactus store? :D Not sure on any of them, I grow, buy, sale, trade, receive as presents and rescue plants. I have more not picture and the Mammillaria parkinsonii was purchased at a store that doesn't sell cactus ...

I wanted to share my Mammillaria karwinskiana and others taken today in bloom as are a lot of my Mammillaria.

Been in the ground for over 20 years, no flowers yet. I do take off all normal columnar growth. I get about 8 to 10 each year. The plant is easily 4 feet in diameter and 4 plus feet tall.

I had an 8 foot long branch leaning towards the sun and decided to cut it out so the whole plant won't fall over. I cut the stem into 3 pieces and rooted them in 5 gallon containers. One year later they were rooted well enough to be planted out in the yard. Each were trimmed about 24 inches each.

Plastic pots: squeeze the pot. If it is hard and not forgiving, root bound. Clay pots: I have had the pot split/crack from being root bound.
