The plants are slow growing and leaves start turning yellow and do not look healthy. I cut off dry leaves, but I water every day right now because of the heat. I was watering every other day. Temp. here, 100 degrees. What do they need?
More water is what they need. While you may be watering everyday, it may not be enough. I would try either watering for a longer period each day or twice a day. Make sure that you are watering either in the morning or the early evening so that the plant has the best opportunity to take up the water before it evaporates.
