Planting

From Early Summer TO Late Summer

'Cereus' typically don't like direct afternoon sunlight and should be in partial shade through the hottest hours. They can take direct sunlight in the morning and afternoons. A rich, fast-draining cactus mix is ideal. To plant, do this preferably during the warm season. To repot a cacti, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.

 

Propagating by cuttings

From Late Spring TO Late Spring

'Cereus' are propagated from stem cuttings. Most cuttings require time to dry and produce a callus on the wound, this can take from a week to a day depending on size and type. Use John Innes No 1 with up to 30 percent by volume of added grit and keep the compost on the dry side to prevent the cutting rotting off. Always check what your individual specimen will require.
