Good info here, for sure. Amarillo is VERY dry most of the year. The water would pool above the ground, and I would have to wait in order to give them what water they've been getting. I've been watering in the evening, but it's supposed to get down to 31° tonight, so I'm not sure if I should be watering in the morning instead, but if they've been dehydrating for the past week, then I think I'll go ahead and give them each a full gallon this evening. Not knowing how much to water is totally newb, but that's where I am - afraid of both under & over-watering.
It's why I'm so grateful that the good folks here are willing to help along the way. I think that next time I go to town, maybe I should pick up another bag of mulch. Hopefully another layer might help the soil retain more water. Thanks again for all the input. Much appreciated! Cotton
