That is new growth, and it looks like growth that has reverted to the normal form 9Not crested0. If you really want the crest to grow you should remove any normal growth (not crested).

Thank you, succulentfan. But how do I remove the normal growth? Just use a knife and cut away that "straight" section?

Thanks again.

Xuan,

Yes, but you might want to dip your cutting instrument in alcohol before you make the final cut on each section - this ensures the plant that you've cut has a final and hygenic excision. And of course have some lukewarm water (to staunch the flow of the E. sap) and take care to not come in contact with the sap.

I remember the day I had to trim 25' Euphorbia ingens trees that had branched too much. While I didn't get burned, there was mild tingling for the second part of the show. I looked like a riot cop for the G20 - full clothing (two shirts!), boots, face shield, gloves, the whole bit. Then my friend, in shorts, a muscle shirt and flip-flops steps up and whacks away at the tree for a good half-hour, with nary a drop of latex landing on him. It was just one of those Zen things, I guess, or I intended to be awfully clumsy.

I have owned a seen a lot of Euphorbia lacteas in southern California, some large, yet never seen a flower on one.. .I think perhaps we are a marginal climate for this species and it wants a warmer, more humid climate to bloom in.

Xuan,

As an FYI, the above advice is usually something you might consider with a larger plant, which yours will be some day. I didn't want to sound alarmist, but an ounce of prevention is worth a pound of cure.

Some people are not bothered at all by Euphorbia sap, and others are, and it also depends on what species Euphorbia it is.

You know, now that I think about it I've never seen one bloom here either. Next time I make it to Cactus King I'll ask him if his ever bloom.

Anything can cause contact dermatitis. I've never been bothered by the sap but just let me look at a mango and I'm in the ER.
Tally HO!
