A watering bag suits a young tree with a trunk of 1 to 8 inches, while a soaker hose suits a larger, established tree whose roots spread well beyond the trunk. Both release water slowly so it soaks 12 to 18 inches down to the root zone instead of running off.

Why does tree size decide between a hose and a bag?

Because the water has to reach where the roots are. A young tree's roots stay close to the trunk, where a bag releases water, while an established tree's roots spread out to the dripline, the ground beneath the outer edge of the branches, and beyond.

When is a watering bag the better choice?

For newly planted and young trees within the bag's size range. Fitting a Treegator Original Slow Release Watering Bag around the trunk takes under 5 minutes with no tools, and for most new plantings it is filled once a week.

When is a soaker hose the better choice?

For established trees, and for trunks over 8 inches or branches lower than 25 inches, where a bag will not fit. Laid around the dripline, the hose is left running for several hours so water seeps slowly into the soil.

Frequently Asked Questions

How much water does a tree need from either method?

About 10 gallons per inch of trunk diameter, applied slowly.

Can a soaker hose be used on a young tree?

Yes, laid in a ring over the root ball and run long enough for the water to soak deeply.

Which method needs less attention?

Usually the bag. It is filled about once a week, while a hose has to be turned on and off for each watering.

Do both methods work in sandy soil?

Yes, though sandy soil drains quickly and usually needs more frequent watering.
