Hello, my Euphorbia is quite small and it's turning black from the stem upwards.
Any advice?

Central Phoenix -- I find Euphorbia mammilaris variegata to be an easy Euphorb to grow outdoors in the ground here in Phoenix. I have two plants in the ground and others in pots. The in-ground plants have different micro-habitats with one having light partial shade and once-a-month water and no winter protection. It is slightly more healthy and grows faster than the other, which is in deep shade with slightly more water and is protected under a cold frame in winter.

I have been successful in growing this plant on the East side of the house, under the very spotty, very light shade of a Palo Verde tree, for the duration of the morning hours until 1PM (at June 21, summer solstice) the shade of the house moved over the plant for the rest of the afternoon. The plant is exposed to extreme dry heat at 110 degrees (and even above), and watered 1-2 days after the soil dries out. In winter, when temperatures drop to below 34 degrees at night, the plant is brought indoors and kept very dry under a skylight. Watering during the winter months (November-March) is cut back severely. Watering always occurs in the morning - never in the evening - with very hard well water.

I'm trying this for the second time here in the bay area.The first time it rotted in it's pot one winter. This time I planted them in ground with other tender succulents.That's another point,I really have strong doubts it is hardy to 20f. I would guess like most tropical Euphorbia's, below freezing is close to certain death more or less. Planting a day before November isn't best timing!,but this is California where if it isn't hot or cold..then its always in the middle.

Here in southern California this one doesnt' need much frost protection, but guess it depends on what the low gets to. So far, lows into the high to mid 20s don't affect this plant much. At new home in Acton, where got down to 22F this year, not a hint of cold damage, either... hardy! It is prone to rot when it's not growing much and overwhatered, but that seems to be a warm weather problem for me. EAsy plant here- great for pots and for landscaping as well. Tolerates a good deal of drought, but has its limits there, and have seen many kill their plants by never watering them. Handles full sun, here, too, even if over 110F. Not quite as reliable in a very shady situation, particularly if moist, or planted in soils that hold a lot of moisture.

Needs frost protection in Phoenix. Min. temp. is 45F. Light shade. Keep drier in Winter. Propagation thru cuttings, seeds. Take branch in Summer, wash latex, let dry for a week & plant. Do not water the cutting until it shows a fair amount of growth. If temps are low, may not be any growth for several months. Be patient!

A great addition, it's color is great against the green variety.

An elegant cousin with white-green coloration. Given outdoor direct sun it takes on a pinkish caste. It's a beauty!

Like all Euphorbia HANDLE WITH CARE, the latex/sap is dangerous and can cause skin rash, itching and general discomfort.
