(uptempo music) (static crackles) (lively music) (upbeat music) >>We're at the Gardens at Maymont with horticulturist Peggy Singleman.

And I know you're using a number of interesting devices for your watering here, and one of 'em you call the Gator.

>>Richard, this is a gator bag.

We've got many of them here at Maymont, and as you can see, they fit around the trunk of a tree very nicely.

And then what you do is you fill 'em with water through the opening.

(water splashing) And once the bag is full, it holds about 17 gallons of water and it lets it out very slowly through small holes at the base of the bag, which means 17 gallons get very slowly watered into the tree, and it's a very efficient method of watering a tree.

Complete water usage.

I say a water-wise gardening method, so all the water would go straight down into the root zone.

You can see some of it starting to seep out slowly as even we put the water in.

>>Well, Peggy, how long does it take for a bag to drain out?

>>24 hours.

In 24 hours, you can unzip the bag and move it to another tree.

Or what we're trying to do of recent is just to leave the bag on the tree and that saves us labor and going back and just adding the water in it at another time when the tree starts to dry again.
