Vegetables Turning Yellow

Question

My vegetables are all turning yellow at the bottom. I have cucumbers, tomatoes, and squash. Can you please tell me why this is happening?

Answer 1

You may not be watering deep enough. Rather than watering everyday, try watering 1-2 times a week for long periods of time, say at least 20 minutes. This will make sure the water gets down deeper and will not evaporate quickly. These articles will have some other suggestions:
