I just heard of a similiar situation and the recommendation was to encourage root growth more than nitrogen for leaves, if it doesn't have any leaves you could burn the plant because it doesn't need much. A bit like burning a seedling.
Don't remember the name of the root growth product.

If it lost everything the plant could be toast no matter what you do.

As long as their is life in the twigs and branches, then they will recover.

I would use a good root stimulator and water it properly. Keep them in a very sunny morning or late afternoon location and watch hope it comes back.

Let's just hope they didn't dry them out so bad, that the roots dried out severely, or died. The roots will just not work and rot away as soon as water touches them.

If you start loosing branches, cut them off leaving the good ones behind. If you don't loose any, keep them on. If you loose them all, then, it's over:-(

Thank you for the advice.

I will try some root stimulating Superthrive. Has anyone used this product? I am bit skeptical but it was the only such product at my local hardware store.

Super thrive is Vitamin B1. Vitamin B1 has shown that in some lab tests it can stimulate root growth. However, every study I have every seen done on plants planted in the garden, B1 doesn't make a lick of difference.

I would suggest you invest in automatic watering system, they are fairly easy to setup and inexpensive. This way you don't have to rely on anyone to water. Program it, test it, and you are good to go.
