Dealing With Problems in the Garden

 
There are lots of things that can go wrong in an ornamental garden; but just as many things that can go right.
If you understand the science and cultural practices that underpin plant growth; you have a foundation for knowing what plants need; and in turn a starting point for ensuring they get the conditions they need for optimum performance.
 
A good ornamental horticulturist must know these things; and have the organisational skills and foresight to see what needs to be done ahead of time and ensure it is done.
 
Consider managing frost in the garden.
 
New plantings in particular will be frost or cold sensitive. Start thinking about preparing for winter in autumn, when the soil is still warm.  In spring the plants will get moving quickly; by summer they’ll be fully established and better prepared to survive the heat and dry.
 
Most frost-tolerant plants can be put in the ground at any time of the year; but are still better planted at a time when they are going to grow for a few months as soon as they are planted. If a plant grows a little immediately after planting; it will settle and overcome the shock of planting. If it is planted at a time when temperatures are low, and no growth occurs; it will be more susceptible to adverse conditions, including disease attack, and frost damage.
 
Don’t plant evergreens in very cold, dry areas with prolonged periods of heavy frosts; wait until spring when the frosts have finished.
 
 
 
Frost-tolerant Plants include:
  • Conifers – especially European and North American conifers 
  • Most herbaceous perennials and bulbs – these have a winter dormancy 
  • Deciduous plants – potted plants can be put in the ground now; bare-rooted plants won’t be available in nurseries until midwinter
  • Lawn grasses – cool season grasses, eg. Bents, Fescues
  • Frost-hardy evergreens – there are many frost-tolerant species and varieties. Check the plant label or ask the nursery staff for advice on the degree of tolerance.
Hardy evergreens:
Acacias – many spp., including A. iteaphylla, A. boormannii, A. pravissima, but use frost guards in the first winter
Arbutus
Buddleia
Buxus
Callitris
Camellias
Ceanothus
Cotoneaster
Diosma 
Eucalyptus – many species, esp. E. pauciflora (Snow Gum), E. nicholli, E. scoparia
Gordonia
Grevillea – many species, including G. ‘Canberra Gem’, G. rosmarinifolia, G. alpina
Hebe
Holly
Mahonia
Nandina
Philadelphus
Pieris – needs shelter from cold (and hot) winds
Prostanthera – most species but use frost guards
Pyracantha 
Rhododendrons – many varieties
Viburnum
 
 
Can Citrus be Planted in Autumn?
Yes, in mild climates autumn is a reasonable time to plant citrus. Citrus tolerate light frosts, many to around minus 2 degrees celsius; though they prefer protection. In areas with moderate frosts, wait until spring, plant in a sheltered position and use a frost guard the following winter.  
 
Planting Tips when frosts are a possibility
  • Dig organic matter into the soil several weeks before planting.
  • Plant into moist soil and keep watering the plant until the cold weather starts.
  • Don’t fertilise the plants until spring. Fertilising encourages new shoots that are very prone to frost damage.
Helping Plants Survive Frost
  • Plant in protected areas – in front of a sun-facing wall, under trees, on slopes, near paving or buildings
  • Turn the sprinkler on before dawn – this stops the frost settling on the plants
  • Use stone or gravel mulches that retain heat
  • If plants are bitten by frost, don’t cut off the damaged parts. This can encourage new, tender shoots that are vulnerable to frost. 
Protecting Plants from Frost
Any barrier that stops the frost settling on the plant is useful. 
Try these:
  • tree guards – make a guard from hessian wrapped around stakes, or use plastic tree guards (available from garden centres, hardware shops and rural suppliers).
  • milk/drink cartons, cardboard boxes or plastic drink bottles – cut the base off and place them over seedlings
  • cloches – glass, plastic or cloth covered frames used to protect seedlings. NB. Don’t remove the guard too early – late frosts can cause the most damage.
