What is a good all round fertilizer for lawn and garden, 10,9,8 was one years ago, no longer available?

Question

Australia, when I say lawn I mean a couple of paddocks of lawn (grass)

Answer 1

The right nutrients for the right application is the right fertilizer.
The best is to pull a soil sample, and see what your lawn/soil actually needs.

But as a generalization 10-10-10, 12-12-12, 14-14-14 all of which are balanced fertilizers (All Three Nutrients N-P-K are in equal ratios). That can be used in gardens and lawns with very little problems. If it is hot, then you might use a slow release Nitrogen to keep from burning the lawn and slowly feeding the plants.

But it really depends on your grass type.

Answer 2

Here in the states we use 12-12-12 a lot for the lawns. Or some use a weed and feed type. I personally let the dandelions grow (form of aerating.) Go figure!

Not only do dandelions have a multitude of uses, what most people who classify them as weeds don’t realize is: they are actually beneficial to lawn and landscape. Dandelions’ deep taproots draw up minerals from the subsoil. And because their roots are so deep, they do not rob grass of nutrients, as is commonly believed. The roots break up compacted soil, increasing aeration. They also emit ethylene, a gas that inhibits the growth of nearby plants.
