Green Thumbs Beat the Blues

Curb the social isolation blues by growing a vegetable garden at home

Before it was condemned by Australians as the worst year in recent history with devastating bushfires and now a pandemic, 2020 was declared the International Year of Plant Health by the United Nations General Assembly. 

In the current climate of social isolation, potential for illness and staying at home to #stopthespread, growing healthy plants - particularly vegetables - can be hobby with many wellbeing benefits. 

From a splash of colour to brighten the walls of your home, to the fresh air and sunshine that comes with a backyard garden, and the nutrients of home-grown produce that you don’t have to compete with panic-buyers for, a healthy vegetable patch is the perfect ‘isolution’ for people staying home - young and old.   

So, what are the best vegetables to grow now and in the coming months, and how do you manage the fruits (or rather vegetables) of your labour? 

What to grow 
Tomatoes: Because of the beautiful and frequent Queensland sun, tomatoes, which are normally grown in hotter months, can grow almost all year round in the Sunshine State. If you’re growing tomatoes from seeds, seedlings should break through the soil from 7 – 14 days, with plump produce ready for harvest in a few months. If planting established saplings, produce will be ready sooner.
Due to their height, tomatoes should be planted with a stake or trellises. As the plant grows, secure it loosely with gardening twine or old stockings. Prune the vine into a single stem to structure the tomato’s growth. As a natural protection against insects, you should companion plant tomatoes with basil.       

Basil: While basil can be grown successfully in an herb garden, studies have shown it grows better when planted with tomatoes. There are a number of different varieties of basil including Thai, lemon, sweet and bush. Each one has different flavour profiles and intensities. Basil will retain its flavour better if you pinch off the flowering tips. 
For the freshest produce, cut the leaves for immediate use. Once the plant starts to die off, pull out the bush and hang it upside down to dry out. The dried leaves can be finely diced for cooking. 

Capsicum: Similar to tomatoes, capsicums grow best in sunny areas with good drainage. 
They only need a small stake to grow straight, and the stem should be secured as it grows. From planting, capsicum can take up to 3-months to grow produce.
All capsicums are green. However, for the best and sweetest flavour, wait until the produce has ripened fully and changed colour (to red or yellow) before harvesting. To protect the plant and encourage regrowth, cut off capsicums at the stem rather than pulling them out. 

Carrots: Grown from seeds, carrots look and grow best when planted in rows. When the bright green shoots of the seedlings are around 5cms (2 inches) tall, usually around 3 weeks from planting, replant your carrots to a distance of 2cm (a little under an inch) apart. When the shoots are 15cms (6 inches) tall, replant again to a distance of 5cm (2 inches) apart. This will prevent crowding and promote growth. 
Produce can be harvested as needed but remember to cut off the green tops immediately otherwise they will keep drawing moisture, making the carrots dry. To protect your carrots from insects, companion plant with rows of onion or garlic. 

Onions: If planting onions from seeds, you’ll have to plan ahead. Onion seeds grow best in seed raising mix, with the seedlings being moved into a vegetable garden once they’re around 8cm (3 inches) tall. Seedlings can be planted straight into the garden. For the best results, create a trench and lay the seedlings down, covering their roots with soil. Within a few weeks, the onions will be upright and growing strong. 
Onions are ready for harvest when their tops are yellow and starting to die. This takes around 6 months, making onions a long-term investment. Spring onions have a much shorter harvest time. They usually shoot within a few days of planting, with produce ready in around 2 weeks. The trade-off is, less fragrant spring onions aren’t as effective as a companion plant for carrots.   

Watering
Remember to water your vegetable garden often and thoroughly. Keep an eye on the weather reports and if rain is expected, hold off watering so as not to over-water your crop, with can lead to the underground produce rotting. 

Weed management
Weeds, both native and introduced, are a problem in all kinds of gardens and lawns throughout Australia. Weeds can degrade the soil by competing for the nutrients, space and water your vegetables need to grow big and strong. 
A combination of an organic herbicide (one that is safe to use around edible plants) and manual weeding, all undertaken on a regular basis will generate the best results for keeping weeds under control. Hoeing your vegetable garden once a week will help stop weeds that haven’t seeded yet from taking root. Hand weeding is required once the weeds have seed heads. Make sure you dispose of the weeds and seeds completely into the rubbish bin (not into compost heaps or the rest of the garden) to avoid transporting the weeds further.  

With produce ready for harvest starting in a few months and through to the end of winter, get your green thumb going and you’ll have a bumper crop of healthy vegetables ready to make delicious soups, stews and roasts in no time.

Condamine Headwater
25 September 2024
The Condamine Headwaters, a critical ecosystem in Southern Queensland, has long faced threats from sedimentation, habitat degradation, and thermal regime changes. The Blackfish Project, dedicated to reversing these impacts, unites scientists, landowners, and the community in a shared mission to restore and protect this vital environment. At its core lies the river blackfish, a sensitive indicator of the overall ecosystem health.  Central to the project's success is the unwavering commitment of landowners like Paul Graham. Inspired by the project's vision, Paul reached out to SQ Landscapes seeking support for a solar pump and tank to divert his cattle away from waterways on his property. Paul's deep-rooted love for his land, captured in his humorous quip "I love my land more than I love my wife," is a testament to the powerful connection between people and place that drives conservation efforts.

When Sophie and Adrian McInnerney began adopting their “paddock to plate” experiment into their lambing business, they quickly discovered how a new and exciting approach to running their enterprise transformed their resilience and soil health. Multi-species cover cropping was the answer, and now their business has become a diverse enterprise that has embraced variations in livestock feed and crop rotation, building riparian fencing, and investing in healthier soils. This has opened the young couple to new opportunities to create new revenue streams, protect their business against natural disasters, drought, and prepare for economic hardships. Their property, “Bellhaven Brook”, located just an hour east of Goondiwindi, was the site of Macintyre Ag Alliance’s latest Multi-Species Cropping Field Day. With the support of Southern Queensland Landscapes (SQ Landscapes), the event aimed to promote the McInnerney family’s new land practices, offering an opportunity to educate land managers in the region of new ways to strengthen their property and enterprise. SQ Landscapes’ Goondiwindi-based Project Delivery Officer Keith Walker joined land managers for the workshop and highlighted how multi-species cover cropping could pave the way to rebuilding healthy soils and farming enterprises. “What was great about visiting ‘Bellhaven Brook’ is that you don’t have to be a scientist to understand this stuff. The idea is to just try and experiment like the McInnerneys did,” Keith Walker said. “These cover cropping systems are all about building your experience, experimenting and slowly developing a healthier and richer soil profile; which is the basis of all businesses; cropping and grazing alike.” Mr Walker said. “It was interesting to see the range of people, the ages from young and old, and the differences in enterprises. It’s a reminder that this genre of agriculture is starting conversations,” he said. “It’s all about implementation on the ground and getting the results for less money and experimenting with what people are doing.”

Cool burns, camels, and funding for local farmers were on the agenda at 'Risdon Stud' as land managers Nick and Liz Suduk hosted the Southern Queensland Landscapes and Department of Resources site visit to showcase the success of the Natural Resources Investment Program 2018-2022 (NRIP). Risdon Stud, south of Warwick, was primarily a high-intensity horse stud, but under new ownership with the Suduk family, the focus has been on restoring productivity and landscape health. “The Suduks participated in the NRIP project, where they received on-site guidance from First Nations fire practitioner Robbie Williams from Fire Lore, for cool burning in native vegetation areas,” Project Delivery Lead Natasha Mylonas said. “This was their first exposure to this type of burning and they have since embarked on a journey towards building their confidence in applying it elsewhere on the property,” Ms Mylonas said. “The NRIP project also supported livestock fencing, largely to exclude cattle from a large patch of remnant vegetation, combined with weed management in that remnant vegetation,” she said. “It is really difficult to muster out of the remnant vegetation, so the fencing has meant easier mustering of the cattle, as well as reduced weed spread and damage to the native vegetation in the patch.” “Outside of the NRIP project, they maintain a herd of agisted camels as part of their weed management strategy and experimented with fire to manage wattle regrowth,” Natasha Mylonas said.
