THINGS TO DO IN SPRING
- Fruit fly programs should be started now.
- Plant and liquid feed vegies (and annuals + spring bulbs) every 2-3 weeks. Continue this as long as you grow vegies.
- Caterpillars, both green and black, are prolific at the moment. Squash them or feed to magpies or spray plant with Dipel, Success or Nature's Way. Derris Dust or Diotomaceous Earth (horticultural grade not the pool stuff!) also work well.
- Feed all plants & lawn with slow release fertiliser like GrowSafe Home Gardener or Eco Prime or screened compost or worm casts dug into soil.
- Feed natives sparingly with slow release fertiliser (see above).
- Apply iron chelate to citrus, camellias, hydrangeas (blue ones), blueberries, azaleas, gardenias, port-wine magnolias, proteas, leucospermums/ leucodendrons & eastern states grevilleas if looking iron deficient.
- Spray new citrus leaves (those about 4-5cm) every 10 -14 days with Eco Oil to prevent leaf miner laying eggs & disfiguring your trees. Don’t spray more than 8 x per season. CLM Traps are also good.
- Mulch pots (use coco peat) & entire garden. Use a chunky mulch like composted recycled tree prunings or pine bark (for acid lovers: blueberry, camellia, gardenia, azalea etc).
- Lightly feed indoor plants. Re-pot if necessary. Keep plants moist but not wet.
- Hard prune plumbago, buddleia. Trim winter flowering natives and exotics, salvias, passionfruit + hibiscus by 1/3.
- Liquid feed dying winter bulb leaves every 2 wks till brown. Dig up or leave in situ (freesias, jonquils, snowflakes, bluebells).
- Thin out fruit trees to encourage tasty large fruit and to discourage biennial bearing (excess fruit one year, none or very little the next). Aim for no fruit touching another.
- Iron chelate gardenias if not done in Sept. In early Oct, sprinkle 1 tsp epsom salts around base then water in with seaweed liquid. Liquid feed regularly for lots of flowers.
- Use Grosorb wetting agent – fork it in, water well, then top up mulch. Treat plants in non wetting soil to some Cassie's Clay or Soil Solver & compost mixed around roots.
- Consider planting a passion fruit vine. Ensure it’s planted at least 2m away from existing fruit trees or shrubs and avoid disturbing roots once established.
- Check mulch. Before mulching, ensure water is penetrating right through to roots before applying. Leave a mulch free space of about 5cm around stems/trunks.
- Keep thinning out fruit as per October.
- Watch for aphids, thrips & spider mite (likes dry conditions). If you must spray, try Nature's Way or EcoNeem. Avoid spraying near bees, wait till they’ve gone to bed, at dusk.
- Feed citrus again (late Nov). Citrus are gross feeders and need to be fed 3 x per year for best results. They love an annual compost application under their chunky mulch.
