What to do in the garden

June

Winter, with its pleasant mild days and cooler nights, is a wonderful time to focus on the vegetable garden. The vegetable garden should be in full production now after autumn sowings and transplanting. As you start to harvest crops, improve soil with a light application of fertiliser and compost before filling the gaps with small fast growing plants like chicory/radicchio, choy sum, coriander, corn salad/mache, endive, ice plant, landcress, lettuce, mibuna, mizuna, miner’s lettuce, pak choy/bok choy, radish, rocket and tatsoi.

I’m a great fan of sowing vegetable seed directly into drills in the garden. At several stages you will have to thin out the seedlings to let them grow without competition. Some ‘thinnings’ end up in a salad, but most of them can be carefully planted into the gaps that appear. After renovating garden beds and sowing seed, net or cover areas to minimise disturbance from curious bush turkeys, bandicoots and cats.

It's important to keep an eye on soil moisture. Evaporation is low this time of year and we can get heavy dews in the morning. The soil can look quite moist, yet can be bone dry below the surface. Poking a finger down into the bed is great way to make a quick assessment, but often a dig with a trowel will provide a much better gauge. Rainfall will now start to trail off until the rains arrive again in November, so a good hand watering or an automatic irrigation system will be needed in most areas to keep the garden in full production. Water the garden in the morning to ensure foliage is dry by nightfall. Cucurbits are subject to powdery mildew this time of year and many gardeners remove this by applying a milk spray (1 part organic full cream milk to 10 parts water).

Continue to lightly mulch the vegetable garden with coffee grounds, lucerne or well-composted stable manure.

Grow tender leafy greens over winter and enjoy dishes featuring chicory, mustard greens, purslane, endive, mizuna, purslane, rocket and spinach. Spinach thrives in the cooler winter months, grows quickly and the leaves are ready to harvest successively from plants in only 3 weeks. Cut leaf varieties, particularly ‘Galilee’ are easier to grow. Warrigal greens (New Zealand Spinach) are also a good mainstay, so keep a large patch going to provide juicy shoots for most of the year.

Vegetable Growing Tips

Starting a vegetable garden

- Choose an area that gets full sun and is not too far away from your house. The mid-winter dash to the vegie patch will be easier! 

- A good, healthy soil is the foundation to success so focus on improving the soil before you do any plantings. 

- Know what to sow, when to sow and how. Every vegetable seed has its own growing requirements. We offer a beautiful heirloom Seed Sowing Guide here and a 2018 Gardeners Diary with space for seed packets, garden plans and notes here.
