NOTES The dormant winter garden
June is the month the garden settles into dormancy for the coming winter.
■ Continue planting cauliflower, cabbage, broccoli, kale and silverbeet seedlings. Bok choy is a winter wonder, continuing to grow despite the weather. A side dressing of lime will be beneficial, especially if plenty of compost has been incorporated into the soil, for strong healthy plants.
■ Broad beans and peas can be sown still while some warmth remains in the soil, but not for much longer.
■ It’s garlic and onion time. Prepare an area with compost and lime for garlic and onions. Both are best planted this month ready for a midsummer harvest.
■ Raising the ground by creating little humps benefits spinach, which hates wet feet and growth is more assured with good drainage.
■ Put unused areas into a winter crop to prevent weeds and to increase soil fertility.
■ Turn over the compost heaps and sweeten with some lime, the worms love it.
■ If using your glasshouse this winter, treat for whitefly — spray and sticky traps are options. Herbs, salad leaves and tomatoes are all moneysavers for winter.
The flower garden
■ Spray roses and surrounds with a last copper spray to kill off the rust and fungus spores, so little can winter over.
■ Check buxus, gardenias and other susceptible shrubs for scale. They are sap-sucking brown bumps on the stems and need a good insecticide or organic Conqueror oil to kill them before winter.
■ Protect new delphinium and hollyhock seedlings with slug bait. They are very vulnerable in the coming months as growth slows down.
■ Mulch the crowns of frostsensitive perennials that are dying down for winter, with pea straw. This keeps weeds at bay and insulates the plants from the coming winter frosts
■ Cover new citrus and other sensitive plants in exposed areas with frost cloth. The next 16 weeks we could have frosts at any time.
Wendy says broad beans and peas can be sown still while some warmth remains in the soil, but not for much longer.
Prepare an area with compost or mulch and some lime to plant garlic and onions this month.
