What does The Green Doctor cover?

Lawn care, plant pests and diseases, soil and compost, Australian native gardens, edibles, water-wise planting and the seasonal jobs that keep a backyard honest.

Is this advice written for Australian climates?

Yes. We write in Australian English and split guidance across tropical, subtropical, temperate, Mediterranean and arid districts rather than copying northern-hemisphere calendars.

Can I write a guest post for Green Doctor?

Yes. Read the write-for-us guidelines and send a pitch through the guest post form. We commission original, useful Australian garden journalism — not recycled product copy.
