Garden tips for August

In the veggie patch


Plant sprouted seed potatoes by digging a trench and cover lightly with soil. As the foliage grows up, hill up the soil – that’s every few weeks.

Sow tomato, capsicum and zucchini seeds indoors or under cover. With winter seed-sowing a heat pad can help germination along.

Stake up broad beans so the spring winds don’t knock them flat. Remember, there’s quite a long wait between the flowers dying off and the pods growing – patience rewards the gardener.

In go the bee-attracting flowers: calendulas, poppies, bergamots, and lavenders are loved by the bees and they’ll be flowering at a similar time to the edibles.

Thyme, bay, parsley and rosemary can take a hammering from the herb scissors over winter, so apply a liquid fertiliser to encourage them to take off when the weather warms up.
 
Rosemary Hedge

Upright rosemary varieties make great hedges and the blue flowers brighten the winter vegetable garden.

Control slugs and snails to stop them feasting on your seedlings.
 

The rest of the garden


Prune hydrangeas and make sure you get the right flower colour: add lime to encourage pink flowers, or Aluminium Sulphate for blue flowers. If you are planting white flowered types avoid full sun – they look best in dappled shade.
 
Potted bulbs

Place pots of sprouted spring flowering bulbs in sunny areas to make the most of their upcoming displays.

Late August is a great time to begin planting hedges and perennial borders for the summer garden. Mulch after planting.

Flowering camellias brighten the last of the winter days, but be sure to clean up fallen petals to avoid spreading camellia petal blight.

The South African plants that give good winter colour include proteas and leucadendrons. As our summers get a bit warmer, these plants seem to ignore a drought and cope in our Auckland clay.

Lawns


A gentle but effective early fertiliser for yellowing or sad looking lawns is Prolawn All Purpose.

Avoid mowing very wet lawns until they have dried out a little.
 

Project for August

Tree planting

Tree planting season. Dig a planting hole to at least the depth of the tree’s rootball and twice the width. For hard, compacted soil, add a handful of gypsum in the hole. Mix the existing soil with Garden Mix or Nutra Soil and carefully place around the rootball, then heel in firmly. Trees and shrubs should be staked in the first few years.
