Yearly Planner

Please note: This planner covers the Adelaide Hills and Adelaide Plains

January & February

  • Time to start planning and making preparations for Autumn planting
  • Water previous years plantings (deep water8-10L per plant) using soil wetter if necessary in hydrophobic soils
  • Regular Seasol applications (every 4 weeks)
  • Check and monitor irrigation systems for leaks and faults
  • Monitor for summer weeds such as Polygonum aviculare, Conyza bonariensis, Senecio pterophorus, Hypericum perforatum, Heliotropum europaeum, Echium plantagineum and summer grasses such as Catapodium rigidum and Lolium rigidum
  • Use appropriate herbicides to eradicate problem weeds
  • Light pruning & tip pruning or dead heading of late flowering species such as Bursaria spinosa
  • Drill and fill olives with 50% solution of glyphosate and water
  • Cut and swab woody weeds such as Chrysanthemoides monilifera, Rubus fruticosus sp. agg and Rhamnus alaternus
  • Selective brush-cutting of weeds low to the ground, this will kill many weeds without herbicide. Remove as much cut weed as possible and hot compost or dispose of in the green waste system
  • Collect seed from Austrodanthonia, Austrostipa, Themeda, Cymbopogon, Chloris Arthropodium, Bulbine for direct seeding or growing tubestock
  • Collect seeds of C4 grasses such as Themeda, Cymbopogon and Chloris
  • Weevils can be a problem due to prolonged warm, dry conditions, especially in mulched areas. Hand control

March & April

  • Time to start planning and making preparations for Autumn planting
  • Prepare clay soils with gypsum ready for planting
  • Water previous years plantings (deep water8-10L per plant) using soil wetter if necessary in hydrophobic soils. Watering should decrease in frequency at this time of the year but continue the same watering volume
  • Regular Seasol applications (every 4 weeks)
  • Check and monitor irrigation systems for leaks and faults
  • Monitor for late summer weeds such as Conyza bonariensis, Senecio pterophorus, Hypericum perforatum, Rubus fruticosussp. agg Heliotropum europaeum
  • Use appropriate herbicides to eradicate problem weeds (such as glyphosate or Brushoff).
  • Drill and fill olives with 50% solution of glyphosate and water
  • Cut and swab woody weeds such as Chrysanthemoides monilifera (boneseed) Rubus fruticosussp. agg and Rhamnus alaternus
  • Heavier pruning can be carried out if needed
  • New garden areas can be prepared for planting in late April- early May
  • Native fertiliser can be applied after the rains have began
  • Early identification of newly germinated grasses can be difficult, take care not to herbicide native species accidently. It may be better to wait for identifying features such as flowers or seed heads
  • C3 native grasses can be cut back in April if the weather is cool and becoming more moist, then Seasol applied and fertiliser
  • Sow seeds of C3 grasses collected in summer, such as Austrodanthonia, Austrostipa, Poa labillardieri into tubes or direct-seed in situ
  • Collect seeds of C4 grasses such as Themeda, Cymbopogon and Chloris
  • Look for sawfly lavae
  • Opportunity for early planting if there has been early heavy rainfall in April

May

  • Monitor for weeds such as Ehrharta longiflora, E.erecta, Avena barbata, Conyza bonariensis Senecio pterophorus, Arctotheca calendula, Sonchus spp., Oxalis pes-caprae, Chrysanthemoides monilifera
  • Use appropriate herbicides to eradicate problem weeds (such as glyphosate or Brushoff) Early populations of correctly identified weed grass species can be targeted with Fusillade
  • Early identified small weed seedlings can be swabbed with a herbicide applicator (available from Trees For Life)
  • Small olives can be mattocked out
  • Heavier pruning can be carried out if needed
  • Native fertiliser should be applied
  • Apply compost to garden areas
  • Early May is an ideal time to plant new areas as there is usually enough soil moisture to plant without additional irrigation and soil temperature is still adequate for growth
  • Monitor for new native seedlings and mark with a cane or small plastic marking flag
  • C3 native grasses can be cut back in early May, Seasol applied and fertiliser. Avoid pruning C4 grasses such as Themeda, Cymbopogon and Chloris as this will set them back over winter and they may die
  • Avoid heavy pruning this month unless you intend to slow the growth of a particular plant
  • Begin looking for native bulbs such as Arthropodium
  • Begin looking for native ferns such as Cheilanthes and Adiantum
  • Time to use a non-toxic iron chelate based snail and slug bait around seedlings

June & July

  • Use appropriate herbicides (such as glyphosate or Brushoff) to eradicate problem weeds
  • Early populations of correctly identified weed grass species can be targeted with Fusillade
  • Small olives can be mattocked out

  • Native fertiliser can be applied
  • Selective brush-cutting of weeds low to the ground, this will kill some weeds this time of the year without herbicide. Remove as much cut weed as possible and hot compost or dispose of in the green waste system
