Purslane problems

Friday, 18 Nov 11 Sunny 31°C / 88°F

So I have two Purslane plants. One is still in the Greenhouse, the other was planted out to the herb garden 12 days ago. The one in the herb garden has taken a turn for the worst (putting it mildly) over the last few days.

I first noticed some of the leave were getting dark green/black makers on some of the leaves, and half of the leaves seem to be be bleaching out. it was almost like the leaves were painted green, and the paint was slowly sliding off the leaves.

That was about 3 days ago. The photo was taken this morning, and as you can see, most of the leaves are now shrivelled up. Does it simply look like it’s too sunny out there for it? Every other plants is doing fine, it’s only this one that is showing damage. I know it is very succulent like, but the growing instructions I’ve found say it grows virtually anywhere. The leaves have curled up and shrunken, more than dried out. Could it possibly be too much water?

If anyone has any suggestions, I’d love to hear them.

    Did you ‘harden it off’ before you moved it outdoors? From your description it sounds like the UV has hit it hard – pale leaves is a giveaway, especially when you mention a greenhouse in its history.

    Purslane grows as a weed here and is at its best in the extreme heat. All else can be fading under the sun’s onslaught but the self sown purslane will be looking as “proud as Punch”. The volunteers will grow anywhere, water isn’t a deciding factor in that decision. They do better with water (in the pots for example) but they grow well in dessicated sand too. :-)

    Hmmm. It came in a small pot, which I left sit in the shadehouse side of the greenhouse for about 2 weeks before it went out. That’s about the most hardening it can get. We have had several days of 35 deg. temps just before it started to go downhill.

    With @graibeard on this one … a succulent planted out in full sun probably burned the fleshy leaves, and watering would have been ineffective since the plant was not taking it up. Is your soil too nutrient rich for this particular plant? If you put the other one out, perhaps do so working up to full sun.

    Here also purslane is a weed, but I encourage and eat any volunteers :-)

    The soil I’m putting is is a mixture of 1/3 coconut fibre, 1/3 manures and 1/3 sandy garden soil, so maybe it is too rich? Thanks for the info.
