Planting Information > What to do When > September

Custard Apple: Leaf loss should occur this month. Low irrigation. Mulch trees. This month is the best time to prune custard apples. 1/3 of old wood needs to be taken off.

Figs: Pruning can be carried out. Be very vigorous. 1/3 can be cut off. Figs are only produced on new wood of the new seasons growth. Give trees a good feed of organic fertiliser with sulphate of potash. Mulch well.

Lychee: Increase irrigation. Flowering should start this month. Fertilise trees with an organic fertiliser with potassium sulphate. Give mature trees 1kg and small trees ½ kg.

Low Chill Stone Fruit: Carry out final thinning. Stone hardening will occur this month. Continue with high irrigation. Prune out water shoots and dense foliage for better sized fruits. Use fruit fly control programs, for example netting or an attractant method.

Mango: Don’t let trees dry out. Once flowering occurs spray with copper based spray or leaf microbes for anthracnose, if visible.

Passion-fruit: Vines will start to grow this month. Apply a little organic fertiliser with sulphate of potash and mulch vines at least 2 to 3 metres out from the base, 1kg for large vines and ½ kg for smaller vines.

Pawpaw: Spray with wettable sulphur in the evenings for spider mite.

Persimmon: Flowering will start in early varieties. Mulch trees. Low irrigation.

Strawberries: Apply small amount of organic fertiliser with sulphate of potash. Keep up irrigation. Pick fruit when fully ripe.

Bananas: Don’t let stools dry out. Keep fruit covered and cut off bells.

Citrus: Flowering will occur this month. Increase irrigation. Fertilise tree with organic fertiliser with sulphate of potash, 1kg for large trees and ½ kg for smaller trees.

 
Chores for September

  • Tip: Prune young Native Shrubs as they grow. Sow seeds and plant seedlings of any herb except basil (wait until days are really warm for that).
  • Plant out any flower and vegetable seedlings from the June container sowings.
  • Sow Flower and vegetable seeds for summer plantings.
  • Attend to your fruit trees as per above.
  • Plant potatoes and sweet potatoes in the vegetable garden. mound up soil around potatoes already growing.
  • Plant avocados, custard apple, lychees, macadamias, mangoes, sapodillas, and star fruit.
  • Plant an indigenous Queensland Tree Buckinghamia celeissima (ivory curl) Calistemon viminalis (weeping bottlebrush).
  • Plant shooting dahlia tubers for early blooms.
  • Keep annual flowering seedlings weeded, and maintain watering if necessary.
  • Plant bromeliad suckers in shady places.
  • Take cuttings of poinsettia.
  • Deadhead perennials and annuals as they fade to encourage further flowering.
  • Tip prune new growth on native shrubs to keep them bushy.
  • Tidy shrubs with secateurs or hedge trimmers as they finish blooming. Cut back new growth by at least a third on rangy shrubs Philadephus and japonica. Very old wood can be sawn at ground level.
  • Prune bottlebrushes just below the flowerheads as soon as they start to turn brown.
  • Aphids often spoil flowers at bud stage. Rub or hose them off whenever you see them.
  • Slugs and snails relish young plants and damp conditions. Lay bait traps and surround new trees with gravel to deter these.
  • Maintain the fertilising.
  • Sprinkle liquid fertiliser fortnightly on quick growing plants such as vegetables and annual flowers.
  • Spread complete fertiliser or blood and bone under the outer leaves of shrubs, climbers and young ornamental trees and water it in ( fork holes help penetration).
  • Mulch plants with home-made or mushroom compost.
  • Tall growing perennials ( Dahlias, Easter daisies, Delphiniums, for example) and annuals (sunflowers for example) generally need to be staked.
  • Use stakes that are as inconspicuous as possible, and hide them amongst the foliage if you can.
  • Stake tuberous plants like dahlia at planting time (to avoid skewering tubers later) and other kinds when they are in bud.
  • Use only enough sakes to support the plant.
  • Tie with soft material such as lengths of pantyhose leg.
  • Staking trees and shrubs is often avoidable if you choose small, sturdy plants that will anchor themselves as they grow, spindly ones can be cut back.
  • If staking is essential, use two or three stakes and tie with pantyhose or binder twine.
  • Remove stales as soon as plants are stable.

This perennial vegetable is related to melons and zucchini but is best grown over a fence or substantial trellis rather than o the ground . It is very much at home in frost free Queensland, where it will fruit at least twice a year. Now is the time to plant chokos.

  • Prepare a wide deep hole in well drained position, enriching he soil with compost and animal manure plus a cup of Organic Xtra.
  • Buy or beg a whole fruit and wait until it sends up a shoot.
  • Half bury the fruit on an angle with the shoot pointing downwards.
  • Water well, and continue to water in dry weather. This vine will grow rapidly.
  • Pick and eat the fruit while it is young and tender.
  • Once a plant is established it should receive about a cup of Organic Xtra every spring.
