The Beauchamp Park Rose Garden is located in the NW corner of Beauchamp Park (next to Rose Street).
Horticultural practices used in the rose garden are in keeping with Council's efforts to incorporate the principles of ecologically sustainable development into Open Space maintenance activities, such as the use of organic fertilisers and mulches, the use of pruning techniques which reduce the likelihood of disease and the use of environmentally friendly pest and disease control techniques.
The following is an outline of general maintenance and development activities in the rose garden:
The major winter pruning is carried out in late July. Any stems with dieback are cut back, crossing branches are removed, the inside of each bush is opened up to maximise air flow and light penetration around the foliage, and pruning tools are dipped in methylated spirits between the pruning of each bush (or between cuts if die back is present).
A further light pruning is undertaken in February. “Dead-heading” (removal of dead flowers) is carried out during the blooming seasons.
Pest and Disease Control
After pruning in winter, leaf litter and the existing mulch which may harbour fungal spores are removed. Soil is cultivated and weeded, then plants and surrounding soil are sprayed with lime sulphur to help control scale insects and fungal diseases.
EcoCarb and ECO-OIL are used during the humid months to control fungal diseases such as black spot.
Aphids on new growth are sprayed with soapy water. This non chemical control method is used so that the presence of beneficial insects such as predatory wasps, which help control aphid numbers, is encouraged.
Following cultivation and spraying of the soil with lime sulphur after winter pruning, a new layer of organic mulch such as lucerne or “Green Life” (recycled green waste) is laid.
Roses are fertilised with natural, biodegradable fertiliser pellets, and Patons Rose Food, every 6 weeks during the growing season.
Apart from watering in of fertilisers if there has been no rain, only very occasional hand watering during very hot weather is required. The soil’s high clay content results in good water holding capacity, and the use of mulches reduces evaporation and regulates soil temperatures.
At times it is necessary to replace selected existing roses that have lost vigour and have low pest and disease resistance. There are also gaps in some beds that need filling. In winter 2009, 58 new roses were planted. The roses were supplied by a leading rose grower in Victoria, which also supply roses for the Royal Botanic Gardens, Sydney. The following varieties were chosen for their vigour, pest and disease resistance, growth habit, flowering pattern, flower colour and perfume:
- Mister Lincoln (dark red)
- Diana Princess of Wales (pastel shades of white, lemon and pink)
- Queen Elizabeth (pink)
- Sylvia (pink)
- Fragrant Cloud (orange/red)
- Golden Fairytale (yellow)
