Bruce Higgs of Darvill Nursery visited our club to talk about Plant Nutrition and Terrorism. Before we end up on any watch list I want to make it clear that the last word of his subject had to do with how the allowed component percentages of fertilisers have changed since 9-11, not with a how-to demonstration 😮
Bruce gave us some great information about how to get the most out of your plants. He said the key things to consider are: the location of your plant, soil type, use of mulch, water, pruning and fertiliser. Professionals also do things like leaf analysis, soil testing and local plus global expertise. We may not all have a lab at our disposal but we can get an inexpensive pH testing kit and tap into online resources to help us improve our plant health.
Some online tools Bruce suggested we use include:
- Identifying plant disorders – check out the table at the bottom of this page http://www.extension.umn.edu/garden/fruit-vegetable/diagnosing-nutrient-disorders/
- Understanding the interaction of nutrients in your soil. He used Mulder’s Diagram to demonstrate this. I found a good site with the diagram and a bit of discussion about it here: http://apal.org.au/perfecting-your-orchards-nutrient-balance/#
He gave a lot of information about specific plants and what p/n & k/n ratios would yield the best results. It was fascinating and a little bit intimidating but I know we all left with more understanding of what our plants might need and the pros and cons of different types of fertilisers.
Our next meeting is August 4th when Robyn Bible talks about Geraniums and Pelagoniums . It’s also our AGM.
Don’t forget to check out the gardening column in the Hills to Hawkesbury Living Magazine. It appears in every issue and features information about the goings on in this club.
