The Tree Camel was invented in Australia by a horticulturalist for the expressed purpose of efficiently establishing trees in the Outback. It works wonders on most trees that homeowners install (up to 2.5" in caliper). It holds 5 gallons of water and drips continuously for 2 weeks. Please note, you will need three stakes to set up your Ooze Tube. Since most anything will do, and the freight cost associated with shipping wood is often prohibitive, they are not included. You can, however place a separate order for stakes, and we'll supply the perfect ones!
