2003 update click here Experiment 2 - Using cling-film and salt to retard camphor re-growth. In the first week of March, 2002 we cut four medium sized camphors in the Lower Gully and used the logs in the People Garden. Two weeks later I drilled 30mm holes into the stumps and filled them with alt. I then used a handheld cling film dispenser (the type used in packaging) and rapped the tree stumps in cling film. I left one camphor stump without cling film. Four weeks later the results are: 1. all camphor stumps show significant re-growth. The unwrapped stump had many shoots up to 30 cm long. I cut them off with a machete and one week later they had re-grown as shown below. 2. The wrapped stumps also showed r-growth under the cling film. But the shoots had been unable to pierce the cling film anywhere. They looked retarded and shrivelled under the film. There was some re-growth in areas that were not covered with film, especially low on the ground. However, this re-growth lacked vitality and was less than 2cm long. 3. I noticed that on a hot day there was a significant amount of condensation under the film. The salt was still present and it is possible that the atmosphere under the film may be quite salty. 3. The most interesting result was one stump which had been cut about 1.2 meters above ground. I drilled two holes into this stump and filled them with salt. I then wrapped a single strip of cling film around the stump just covering the areas of the wholes to seal them somewhat. This stump sprouted at the very top but the sprouts were uncommonly weak and retarded. 4. Summation: so far the cling film experiment shows significant promise. Especially as it took very little time and was very cheap. |
