[Arid_gardener] Argentine Giant Cactus

[Steve Dugan]

We have an Argentine Giant Cactus in our rear yard that was planted in May
2004.  Our property is a true east/west exposure with the western exposure
on our rear yard.  The cactus had been growing well and it had flowered this
year.  Approximately 2 weeks ago, the long arm of the cactus broke
completely off.  I found it lying on the ground near the plant one morning.
We have a drip system and the cactus plants in our garden are being watered
twice a month.

My first question is why did the large arm break off?

The plant is now turning yellow.  Is that caused by sunburn?  

How should I be caring for the plant?
