Seasonal Gardening Tips for October
In October, we move into our fifth season here in SE QLD. ‘Sprummer’ is a highly changeable period during October/November, where we transition from spring into summer! A time when climate conditions can be very unpredictable.
Based on my observations and keeping notes on patterns over 21 years, this is a time when we need to be prepared for almost any kind of weather! We typically have very unstable and variable conditions, often with little to no rain. We can suddenly get a heatwave or storms (often with intense heavy rain and localised flooding, gusty winds, hail or everything at once); a random cold snap; drying winds; or early humid weather. Quite confusing and challenging for gardeners and plants alike! Follow my Subtropical Planting Guide.
Based on the Bureau of Meteorology’s outlook, we can expect warmer and drier conditions than average. When we do get storms, they are forecast to be less frequent but likely more intense with potential damage to our gardens.
I always have shade cloth structures handy (made with bamboo stakes and zip ties) to help protect plants when needed:
- Provide shade on hot days;
- Shelter against heavy rain/storms/hail; and
- Wind protection for vulnerable leafy greens that dry out quickly and suffer stress.
Shade cloth and netting are very adaptable and can be made into portable or permanent structures to protect your crops.
Our grace period with fewer pests over winter/spring will soon be over! Watch for aphids, bronze orange bug, citrus leaf miners, QLD fruit fly and grasshoppers. Exclusion netting and traps are useful strategies. Hungry birds feeding young in their nests are keeping any newly hatched grasshoppers to a minimum in my garden. One problem I don’t have to deal with - yet! Keeping your birds happy with clean water encourages them to provide free pest management services.
With so many fruit trees in flower now, it’s essential to attract pollinators to your garden or be prepared to hand pollinate. At and after fruit set, trees and fruiting crops have a high need for moisture and nutrients. Mulberry trees can be cut back during the new moon phase to encourage new flowers and the next harvest sooner. Be quick!
A shallow bee bath provides water for pollinators and beneficial insects. An ‘insectory’ garden with a variety of nectar-rich flowering herbs, vegetables and perennials encourages predator insects to keep seasonal pests under control.
What to Plant Now
Sow broccoli, rocket, chard and peas as seeds and harvest as young microgreens. Ready in 7-21 days. I sow Broccoli di Ciccio, a warm season variety, which I pick through to December. It has a long harvest period for side shoots. Rocket prefers moist soil and some shade if growing to maturity. Otherwise, allow it to flower and provide free seeds.
It’s a good time for zucchinis with enough warmth before high humidity sets in. Swap ‘Slow Bolt’ coriander for perennial Mexican Sawtooth variety to take you through summer. Perennial summer spinach varieties like Suranim, Brazilian, Ceylon and Okinawa are coming out of hibernation and will provide spinach leaves during our hot humid weather when our winter varieties ‘check out’! If you haven’t planted these yet, now is an ideal time to do so.
Sow turmeric and ginger this month (ideally 17-18th and 24-25th October with the moon cycle) along with other root crops like beetroot, carrots, sweet potato, yakon and radish. Asian greens, basil, beans, capsicum, celery, chilli, chives, choko, cucumber or cucamelons, eggplant, kale, leeks, melons, mustard, okra, oregano, parsley, pumpkin, rosemary, sorrel, spring onions, thyme, tomatoes and warrigal greens can all be planted in October.
Swap to heat-tolerant ‘loose leaf’ lettuce varieties like ‘Salad Bowl Red’ or ‘Green’; ‘Little Gem’ and ‘Parris Island’ Cos; ‘Royal Oakleaf’ and ‘Summer Harvest’ that are slow to bolt. Lettuce only needs 2-3 hours of morning sun and shade from noon onwards as well as constant moisture. Self-watering container gardens are ideal for all leafy greens and many herbs. Find or create a suitable microclimate and succession plant for lots of luscious leaves.
Take cuttings during the new moon cycle and propagate for quick root development. Who doesn’t love free plants?!
Summer fruiting crops are great to plant now. Make sure your fruit trees and gardens have been topped up with compost and slow-release nutrients as well as mulch. Strawberries need consistent moisture to develop new runners.
Green Harvest has a wonderful organic plant nursery (just outside Maleny, SE QLD) and an inspiring display garden. They have a free Organic Gardening Resource Guide you can order online. They also open on the third Saturday of the month from 7 am - 12 pm when the Witta Farmer’s Market is on (Saturday, October 19). You can pick up veggies at the market that day and visit them at the same time for seeds and plants.
Dave Jarrett at The Garden Shed Nursery at Palmwoods is an experienced and knowledgeable soil agronomist and sells organic fruit trees and gardening supplies including chemical-free mulch and fertilisers. Worth a visit and chat, and he can organise soil testing if needed.
If you’d like to feel more confident rather than frustrated and unprepared, or just need a helping hand with one-on-one personalised expert advice and support for your garden, consider my onsite garden consultation service. I’d love to help you maximise space, provide design ideas and tailor advice to what you need. Read what a few of my clients say.
Until next time, enjoy the harvest!
