After using 58 gallons in the morning and 213 gallons in the afternoon, there were 424 gallons remaining in the rain barrel. The calculations involved subtracting the used amounts from the initial 695 gallons. Therefore, the total left after watering both gardens is 424 gallons.

Let's solve the problem step by step:
Starting water in the rain barrel:
695 gallons
Morning use (herb garden):
58 gallons
695 - 58 = 637 \text{ gallons left after morning}
Afternoon use (vegetable garden):
213 gallons
637 - 213 = 424 \text{ gallons left after afternoon}
