Buying tube stock saves time, effort and most importantly money. When we refer to tube stock we mean forestry tubes which are 50mm wide by 120mm tall. These plants have well established roots and are ready to hit the ground running (no pun intended). In fact, many people will report that the plants they buy in tube stock catch up to their bigger counterparts in no time at all. Like anything new, these tubes just need to be watered in well, especially through their first summer in the ground. See the below range of grasses, shrubs and groundcovers for an example of the sizes you can expect when purchasing our tubes. 30cm ruler for size.
