January: Perth Gardening

This is my personal growing calendar for Perth conditions during the month of January.

I will talk about local conditions, what worked as expected and what didn’t or was surprising. 🙂



With an average temperature of 31.5 degrees Celsius and the lowest average rainfall of the year, January is hot and normally dry. Very challenging conditions considering the fierce sun and watering restrictions.


Very little that is not in shade.


Spray with Dipel and pyrethrum.

Add more wetta-soil to areas experiencing run off and where you want plants to put down deeper roots.

Add nitrogen and potassium to fruiting plants. Sparing add the same to your lawn.


Plant roses nor citrus.



A strange Jan. Most rainfall recorded in 20 years.

Chilis are all going gangbusters.

Tomatoes gave a steady crop although cherry tomatoes less than larger varieties like Romas etc.

I spit and replanted galangal successfully for the first time.

I transplanted a potted Pepino successfully and a cutting survived too for the first time.

Dipel is very good at killing caterpillars though I noticed a natural decline in cabbage moths versus last December.

Pyrethrum used once as a preventable. I saw very little in the way of aphids.

My lime and lemon tree are starting to heavily fruit. I gave each a small bag of dynamic lifter and watered in well.
