Mine always do the same thing. I start with transplants shipped from Texas. They always (ok, almost always, once or twice they weren't in great shape upon arrival) come nice and green, and go through a sad looking phase where a bit of the existing foliage turns brown and they look bad. Then, they perk up, kick in, and grow.

I wouldn't be too concerned unless there are other signs of trouble, such as rotting at the base.

I think youu planted them too early and watering too much. I wouldnt even water them besides the first initial watering after planting.

Thank you for the responses.

I may be watering them too much as obrion said. I just don't like seeing the soil dry at the top - so I water them.

In regards to setting them out too early - I'm not sure if this is the case. They were set out over two weeks ago and they were doing dandy until the past couple of days. The only thing that I can think of is wind burn, possibly belated transplant shock, too much sunlight, or too much water.

If they were put out too early, I would have thought the issues would have happened at least a week or more ago - especially when night time temperatures were lower.
