cool Climate - March

BLUE SEA HOLLY

Blue thimbles on vibrant stems will handle even the toughest garden conditions. This spikey character adds interest to our border, curious amongst the Agastache and Coneflowers. A superb cut flower.

CABBAGE MINI WOMBOK

A baby Chinese cabbage with crisp, almost white heads to use in salads, stir-fries or pickled for kimchi. Best grown with plenty of water and in rich soil for optimal results. Be sure to keep the slugs and snails away as they like it as much as we do. Quicker to harvest than other cabbages.

KALE TUSCAN BLACK

The kale that launched this superfood! A culinary champion in the kitchen and lauded by seasonal chefs. Also known as Tuscan Black, it grows like a mini palm tree with elephant-grey leaves that can be picked continually from 8 weeks. Perfect for light braising in butter and verjuice.

cool Climate - April

BROAD BEAN AQUADULCE

A heavy cropping early strain with fragrant black and white flowers. Wonderful emerald green beans are one of the first treasures of the spring harvest. Tender beans delicous either braised or fresh in salads or dips. Older beans can be blanched and peeled for treasure inside. Plus like all members of the legume family, Broad Beans are one of the most effective green manure crops, adding valuable nitrogen to the soil. Reward your garden and plant a crop today!

CAULIFLOWER MINI

Harvest in 90 days from transplant for mini pure-white compact heads. Suited to warmer regions, plant at 20cm spacings. Will form larger heads if left in situ but will need 60cm spacings and more time to develop. Yields up to 3-6kg.

warm Climate - March

BEETROOT BURPEES GOLDEN ORGANIC

Dating from before 1828, this orange skinned beet transforms with clear yellow flesh when cooked and it is the best baby beet around - declious also when roasted. Exceptionally sweet roots and leaves, also ideal for salads and messy eaters as it doesn't bleed like the red varieties. 60 gram roots at 8 week harvest.

WILDFLOWERS WALTZING MATILDA

A mix of true-blue Australian wildflowers that can only be found in the bush and not in a pot in a nursery! Bring the bush back one seed at a time... Mix includes Billy Buttons, Everlastings, Rock Daisy and Helichrysum

SILVERBEET FORDHOOK ORGANIC

Traditional and reliable with delicious, deep-green leaves and white stems.

warm Climate - April

ASPARAGUS SWEET PURPLE

With a 20% higher sugar content than the green asparagus this purple variety of asparagus has a wonderful mild earthy flavour when cooked or eaten raw. Cut spears back in secod year to increase harvest.

CELTUCE

A lettuce that is also used a celery - strange but true. This ancient Chinese vegetable is much sought-after by those that know it, branded 'the next big thing' in Epicurious, so get ahead of the curve with this new (to the west anyway) vegetable. Grow and harvest young leaves as a lettuce then cut the succulent stems when they run to seed, reaching 30-40cm high.

SWEET PEA PAINTED LADY

Painted Lady was the very first sweet pea to bred by plant enthusiasts in the mid eighteenth century and it's still a favourite for gardeners today. The most fragrant of them all with bicolour pink and white blooms and strong stems for cutting.

hot Climate - March

TOMATO BEAMS YELLOW PEAR

Golden yellow with a shiny skin and firm flesh that preserves well. Enlivens a salad bowl and has ornamental trusses of healthy fruit. Fruits in 7 weeks from transplant. Yields 8.6kg fruit per plant.

LETTUCE HEIRLOOM MIX

A splendid mix of some of our favourite heirloom lettuces that bring colour and flavour from the garden to the table. Includes Tennis Ball, Rouge d'Hiver, Freckles, Tango and Red Leprechaun.

CARROT ATOMIC RED

Carrots are one of the oldest cultivated vegetables and Atomic Red is the deepest red, non-hybrid variety we could find. Red carrots contain the highest levels of the cancer fighting anti-oxidant lycopene. Eat one a day to keep the doctor away ...

hot Climate - April

EGGPLANT SLIM JIM

Ornamental purple leaves and deep purple, cocktail-sized fruits that are ready to pick 13 weeks from transplant. Slice and grill on the BBQ, or dice up for a delicious ratatouille. Yields 2.4kg per plant.

SWEET CORN HONEY and CREAM F1

So sweet it doesn't need cooking, with plump yellow and white kernels. Harvest in 12 weeks. Sow >20 C soil temperature.

MARIGOLD RED MARIETTA

A cheeky little French marigold with bright red and yellow flowers that keep bad bugs at bay, making it an ideal edging plant for vegie gardens. One of the best companion plants for tomatoes.

Things to do in March

Plant spring flowering bulbs

Spring flowering bulbs should be planted this month. Prepare the ground to a crumbly texture and plant the bulbs tip up (except for Ranunculus which are planted 'claws' down!) As a rule, bulbs are planted to a depth that is twice their length. Water in well.

Plant garlic bulbs

It's also time to plant garlic bulbs. Split the head of garlic into individual cloves and plant tip up into a well prepared, and well drained, soil. Garlic likes to be planted about 3-5cm deep and 7cm apart. Planting garlic now will allow it to develop root and foliage over the autumn and winter, then nice plump bulbs in late spring/summer.

Tidy up the vegie patch

Remove summer crops that you are no longer harvesting from and rejuvenate the soil with compost and well rotted manure for autumn plantings. Pick up any fruit that has fallen onto the ground under fruit trees to prevent a build up of pests and diseases.

Growing Weeks By Area

Diggers has divided Australia into five simple sowing areas — Cool, Warm, Hot, Subtropical, Tropical.  These are determined by the number of growing weeks with an average temperature above 15°C each area can expect in a year.

For example, some annuals like beefsteak tomatoes need 16 growing weeks to flower and fruit - this means they will struggle when grown outdoors in Hobart, which only has 13 growing weeks.

Our map tells you at a glance what time of year to sow your seeds for the best results in your area.
