August in the Garden

What fruits to harvest now:

In late winter, it’s only the warmer parts of the country that will have any ripe fruit to harvest, and most of it will be citrus – mandarins, tangelos, grapefruit and lemons.

What fruit to plant:

Evergreen fruiting plants such as passionfruit vines and citrus may still be planted in warm to tropical areas. Bare-rooted deciduous fruit and nut trees and vines should be planted as soon as possible before they start to shoot and flower. Some garden centres may already have them potted up and in flower.

Choose from: 

• Fig 
• Apple
• Pear
• Cherry
• Plum
• Apricot
• Plumcot
• Nectarine
• Peach
• Persimmon
• Almond
• Walnut
• Mulberry
• Pomegranate
• Quince
• Raspberry
• Blackberry

What flowers to plant:

Bare-root roses are still available and, like fruit trees, should be in the ground very soon! Some nurseries sell them already potted up – they can be planted now or left until they are fully in leaf before transplanting into the garden. Spring flowering annuals will in full bloom now, but it’s not too early to start thinking about summer flowers.        

In cool areas, sow seeds into seed trays of:

• Amaranthus
• Bedding begonia
• Candytuft
• Carnation
• Celosia
• Eschscholtzia
• Geum
• Hollyhock
• Linaria
• Lupin
• Nasturtium
• Petunia
• Scabiosa
• Sweet William
• Verbena
• Wallflower

In warmer areas, plant annual seedlings of:

• Dianthus
• Gaillardia
• Geum
• Gypsophila
• Honesty
• Impatiens
• Nasturtium
• Statice

Tips for Indoor Plants:

Plants inside the home assist in purifying the air as well as lending a touch of greenery to your living areas. 

• Natural light is important but don’t stand pots on north or west-facing windowsills where they will be exposed to direct sun through the glass. 
• Keep plants away from heaters and air conditioners that can dry the atmosphere.
• Place a saucer or bowl of water near your plants to humidify the air.
• Wipe leaves occasionally with a damp cloth to keep them clean.
• Feed every few weeks with ready to use Osmocote Pour+Feed Indoor Plants – no mixing required.

Maintenance tips:

If you didn’t have time to give the mower a service last month, do it now before spring when it will be called into service quite frequently. As winter gradually recedes and the days become longer and a little warmer, the lawn will have quite a growth spurt - now is the time to fertilise. The type of fertiliser you use will depend on the health of your lawn. 

• A general purpose fertiliser like Lawn Builder All Purpose Slow Release Lawn Food, Lawn Builder Buffalo Slow Release Lawn Food or Lawn Builder Extreme Green Slow Release Lawn Food (all granular fertilisers that will feed your lawn for up to three months and suitable for all types of grass) will suit most situations.
• However, if you have a broadleaf weed problem, then you may need to use Lawn Builder + Weedkill Slow Release Lawn Food but READ THE LABEL FIRST!  This fertiliser cannot be applied to buffalo grasses and some other lawn substitutes. 
• Buffalo grasses and lawn substitutes can be treated and fed with Lawn Builder Buffalo Weed, Feed & Green Up, a hose-on product that can be safely used on all lawn types. However, it is not a slow release, long lasting lawn food. An application of Lawn Builder All Purpose or Lawn Builder Buffalo after eight weeks will keep the lawn growing strongly through to Summer. 
• Control moss in shady areas with a solution of iron sulfate (30 grams in 4.5L of water) applied as a spray or with the watering will help control it. Re-apply if necessary.
• If you’ve already fertilised the lawn when you notice broadleaf weeds including bindii spreading, use Lawn Builder Bindii, Clover & Broadleaf hose-on to eradicate them.

In the warmer north:  

• Water lawns deeply once a week if there’s no rain.
• Remove weeds either by hand or with Lawn Builder Bindii, Clover & Broadleaf hose-on.
• Apply a Lawn Builder Slow Release granular fertiliser to feed the lawn for up to three months.

Things to look out for and do during the month:

• Keep flowering annuals and bulbs growing and flowering well with regular applications of Osmocote Boost+Feed All Plant Types.
• Finish pruning deciduous trees and shrubs as soon as possible. DO NOT prune blossom trees (Prunus, etc) or Spring flowering shrubs – wait until after they have flowered. 
• As soon as “bud swell” is noticed on fruiting and flowering trees and shrubs, apply a copper-based spray to prevent the occurrence of fungal diseases like mildews and leaf curl. Apply to fruit trees again after flowering, when fruits are just starting to form.
• Last chance to sow a “green manure” crop of oats, peas and field lupins into empty vegetable beds; dig it in to add nitrogen to the soil when about 300-400mm in height.

Pest Control:

• Watch for the caterpillars of the White Cabbage Butterfly on cabbage, cauliflower, broccoli and other brassicas. Pyrethrum will assist or try a cabbage dust.
• Slugs and snails can be active whenever there are young plants around – Defender Snail & Slug Pellets in a bait trap will protect your plants and keep your pets safe.
