As was said in the previous frugal gardening article, gardening can be pretty expensive (although less than most hobbies), and finding ways to reduce costs can be both a fun experience and really useful.
One of the most expensive aspects of gardening is paying for all of the products you need to use to keep certain plants healthy, like nutrient solutions and compost. The only way to limit this expenditure is by reducing the number of plants which need these things in order to live healthily in the environment you’re providing.
You may think how this is possible, but it really does just depend upon the type of plants you’re choosing. If you choose mainly native plants for your garden, everything should be well adapted to the natural environment, and therefore will require less support to prosper, which will have the knock-on effect of reducing your costs.
