Winter Succulent Damage


Hi cactus jungle

A few of my cacti have struggled after the rains.

A tall, green cactus with brown, dried tips—signs of winter succulent damage—stands in front of a window with closed blinds. The cactus has ridges lined with small spines and is next to another smaller cactus.

I have attached a photo and I’m wondering if you can tell me what is happening with this plant.

Is it a lost cause😞? If not, how can I help it?

Thank you
Brian

Brian,

The plant is a Euphorbia, and hopefully it is just the tip that got damaged in the winter. Depending on where you live, they are only semi-hardy here in the Bay Area, so they can take damage to the tip when we get below freezing, or with heavy rains, or especially with both (See: This year.)

You can cut the top part off the plant and it looks like the damage is limited there. Cut at an angle, using a bread knife, and make sure the flesh is clean and white. If there is still some rot there, cut lower. Be careful when cutting a Euphorbia as it has a caustic milky-white sap. Where gloves, long sleeves, and eye-protection. Spray the cut end with Hydrogen Peroxide and put a paper bag over it to keep the sun off it until it is healed. Good Luck!

Peter
