Melbourne & Southern Victoria | 12–18 October 2026
The weekly moon-planting diary — where ancient gardening traditions meet Melbourne weather, and occasionally lose the argument.
Spring is supposedly upon us. The calendar says so, the days are getting longer, and the seedlings are looking increasingly impatient.
Unfortunately, Melbourne’s weather has apparently missed the memo.
This week begins with showers, a possible thunderstorm and a return to chilly nights. The good news is that conditions should improve towards the weekend.
Meanwhile, the Moon is waxing towards its first quarter, traditionally a favourable period for planting crops that produce above the ground.
But the Moon doesn’t have to live in your garden. You do.
The moon-planting diary
Traditional practice — not scientifically established planting advice.
The New Moon occurred on 10 October, beginning a waxing phase that continues through the week. Traditional moon gardeners associate this period with increasing above-ground growth.
The following dates combine the waxing-Moon tradition with the customary leaf, fruit and root classifications. These are approximate calendar-day guides, not exact Melbourne lunar-sign transition times.
| Dates | Traditional classification | Suggested garden activity |
|---|---|---|
| Mon 12 – Tue 13 | Leaf days | Lettuce, silverbeet, rocket, parsley and leafy herbs |
| Wed 14 – Fri 16 | Fruit days | Prepare for beans, tomatoes, cucumbers and zucchini; sow under protection if necessary |
| Sat 17 – Sun 18 | Root days | Carrots, beetroot and radishes, provided soil conditions suit |
There is an interesting contradiction this week. Although 17–18 October are classified as root days in the zodiac-based tradition, the Moon is still waxing. The simpler four-quarter planting tradition generally favours root crops during the waning Moon.
Different traditions, different recommendations. Neither should overrule a suitable planting opportunity.
These dates are consistent with published traditional lunar calendars, although individual systems vary. Mind University
Melbourne’s weather reality check
The Bureau of Meteorology forecast issued Sunday evening, 11 October, indicates an unsettled start followed by improving conditions.
Monday is forecast to reach around 19°C, with showers and a possible morning thunderstorm. Tuesday and Wednesday remain cool, with maximums around 15–16°C.
Thursday could begin near 7°C in parts of the Melbourne area, before temperatures gradually recover. By Saturday, maximums could reach approximately 23°C.
The forecast also indicates a high chance of rain on Monday, followed by substantially drier conditions later in the week. The Bureau of Meteorology
For gardeners, the message is straightforward.
Don’t sow warm-season seeds into cold, saturated soil simply because the calendar says conditions are favourable.
A few days of patience can save several weeks of disappointment.

What to plant now
October offers plenty of opportunities for Melbourne gardeners, particularly those working with raised beds, containers and sheltered urban gardens.
Good candidates for direct sowing include carrots, beetroot, radishes, rocket, coriander, dill and mustard greens. Lettuce and silverbeet can be started in punnets or planted as established seedlings.
Parsley, spring onions and other leafy crops are also worth considering.
For gardeners planning their summer crops, tomatoes, cucumbers, zucchini, pumpkins and beans can be started in suitable protected conditions.
Melbourne community gardening organisation Sustainable Macleod includes many of these crops in its October planting recommendations.
What to hold back
Be cautious with tender tomatoes, basil, chillies, capsicums and eggplants.
Although established tomato seedlings can sometimes be planted outdoors during October, the week’s cold nights make exposed positions less attractive.
Beans, cucumbers and zucchini also prefer warmer soil. As a practical guide, wait until soil temperatures are consistently around 16°C or higher before sowing these warm-season crops outdoors.

Companion planting and crop rotation
Give the legumes a job.
If a garden bed previously supported heavy-feeding crops such as tomatoes or brassicas, consider growing beans there once the soil warms.
Beans form relationships with nitrogen-fixing bacteria, although the amount of nitrogen ultimately available to following crops depends on soil conditions and how the bean plants are managed.
The real benefit comes from planning the next crop rather than treating each season as an isolated event.
The Local Food Connect Melbourne planting guide provides a useful introduction to rotating legumes, brassicas, alliums and cucurbits.
For small gardens, even rotating crops between a few containers can help avoid repeatedly growing closely related plants in the same soil.
This week’s practical job: prepare the summer bed
Before planting the summer vegetables, spend half an hour checking the condition of your soil.
Remove weeds, loosen compacted surface material where necessary and add mature compost.
Check drainage after Monday’s forecast rain. If water remains pooled or the soil is sticky and saturated, leave it alone until it becomes workable.
Install supports for climbing beans and tomatoes before their roots occupy the available space.
Finally, inspect existing seedlings for aphids, whitefly, snails and slugs. Spring growth attracts plenty of hungry visitors.
A torch inspection after dark may reveal more than an afternoon spent blaming the neighbourhood possums.
A final word from the compost heap
Moon planting remains a longstanding gardening tradition, but scientific research has not established reliable evidence that lunar phases improve germination or crop yields. MDPI
That doesn’t prevent us from using the calendar as a framework for observation and experimentation.
Record what was planted, when it was planted, the weather, soil conditions and subsequent results.
Over time, the garden develops its own history.
And that, perhaps, is where traditional knowledge becomes most interesting: not as an instruction that must be obeyed, but as an invitation to observe.
The Moon says plant. The soil says wait.
My money is on the soil.
And if Thursday’s weather is miserable, there is always composting, weeding and a beer.
Talking Manure — cultivating curiosity, compost and the occasional contradiction.
Editorial note: The lunar classifications are traditional guides rather than verified predictions. The weather information reflects the forecast available on Sunday 11 October 2026 and should be checked again before planting. All recommendations assume Melbourne’s temperate Southern Hemisphere growing conditions; local exposure, soil moisture, sunlight and plant health take precedence.
