Our two oldest children, Kate (Grade 2) and Matt Grade 1) participated in the Annual Warranwood Primary School Science fair. Our experiement (that we worked on as a whole family) was to test to see if plants grew better with plain water, soluble fertiliser or salt water. To our surprise the plain water won out over a 4 week period.
It could be that the plants already contained fertiliser and that applying soluble fertiliser everyweek was too much. We measured height, number of flowers, number of buds and general condition. The picture on the left is the first week of our experiment with all plants looking reasonably healthy. The photo to the right is the results after four weeks. On Thursday this week the projects from the whole school were displayed in the school gym. Well done Kate and Matt - good job

It could also be that you used too much soluable fertilizer. Sometimes you really can have too much of a good thing.
They look very proud of their science project. See you this evening for mimos!
