Re: ** Cutting Done Right? Advice? PHOTOS **

This my take on columnar cactus: I would take the tallest piece and cut it to the part that is the greenest. The rest of it looks either dead or just bad. Now for the rest of the cuttings; what is your end goal? If you don't want to cut the tip of the second tallest, it will stay elongated and never...

Re: Greenhouse vs conservatory, and N-facing garden

If the room is adjacent to the house and its footprint is not that deep, full sun exposure could be lost. Years ago I had a lean-to greenhouse facing north and house plants did great. The roof was clear so the upper shelves were okay for cactus, however, the house was in San Jose, CA and there were ...

Re: what is the best way to save & maybe straighten this cactus

There are a lot of cactus that will prostrate as they get taller. Several in the mammillaria family. The damage maybe from trying to keep it upright. Get a 8 inch hanging basket and let it hang. If I'm not mistaking, its natural habitat is rocky outcroppings.

Re: Full sun vs Shade cloth

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 ...

Re: Cactus contest 86: Cactus collections

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. :lol:

Re: Cactus ID and help

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.

Re: Hello from the Central Valley of Northern California

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...
