Good buy or foolhardy purchase? (cacti)

[Essexman]

A splendid little collection. Some Opuntia, 4 X Cleistocactus strausii (white columnar), a Mamillaria bombycina (multi-headed), an Echinopsis (Trichocereus) pachanoi (columnar green), I think there is a little Carnegiea gigantea in there and 2 X Pilosocereus pachyclaudus (columnar blue).

One rather intrigues me, it is front right behind the gloves. It looks like a cactus with a 'cephalium' a sort of cap on top of the cactus. This would make it a Melocactus. Which would be a very nice addition indeed. I might be mistaken.

Keep them indoors. I tend to stop watering at the end of Sept and start again in March. It is important that they have a dormant period. A bit of cactus feed tends to go down well when you start up watering again.

Enjoy them.

Brilliant buy, GH, but only if you keep them all looking like that by next Spring - which you will do if you follow the excellent advice on the earlier posts.

cacti are super easy
. keep dry during the winter

. give a good overhead water once a month

. keep an eye out for mealy bug and red spider mite

. also keep an eye out if the cactus if soft (that means it needs a water)

. watch out for rot (some species are rot prone ie. astrophytum)

also gravel around the pot helps prevent splashback and rot

Put up individual pics ask each one to have an ID.
