The brown coloured tube on the left is pre- perforated and is useful for bedding schemes and densely planted borders.
Black coloured tube comes in both perforated and un-perforated forms. Here I intend to use an un-perforated tube, which allows me to bury it between the planting schemes.
The un-perforated tube is also useful in irregularly planted areas where you simply cut a small hole using a designated tool; and then affix a smaller distribution tube to your plants.
