LANDSCAPE ROSES – “Bred for toughness”
Landscape Roses were bred to be tough and hardy! One of the first was ‘La Sevillana’ in 1977. Since then, many landscape roses have been released and praised by professional landscapers, garden clubs and home gardeners alike. Adelaide has several locations featuring these roses.

Landscape and Groundcover Roses fit easily into any garden design, are low maintenance with continuous flowering and are gentler on the environment requiring little or no spraying.
Rose Breeders around the world focused on inventing new shrub and landscape roses which were capable of coping with hot, dry summers and harsh winters, provided a range of colours with strong repeat flowering all season long and, importantly, excellent disease tolerance. One genetic trade-off was generally little or no fragrance. They can be pruned mechanically if desired. The groundcover type “Landscape Roses” can grow more horizontally than vertically and look good when planted en-masse ingroups, borders or as a hedge.

La Sevillana – Orange-red clusters of non-fading semi-double flowers with petals dropping cleanly. The resilience, disease resistance and repeat flowering made this rose a worldwide hit. Grows 1.2m x 1.5m.
Bonica – Clusters of pale pink blooms with very disease resistant foliage. A hardy and vigorous bush or standard rose. It sets hips in the autumn.

Hot Pink Bonica – A vibrant pink sport of ‘Bonica’ with great repeat flowering, developing rosehips in the autumn. Can grow 1m tall.

Knock Out – Bred in the USA and introduced in 2000. Record-breaking sales have earned it the reputation as the world’s number one Rose Brand. Extremely hardy and drought tolerant with abundant and continuous flowering, producing cherry-red blooms and disease resistant foliage. It does not need deadheading like other roses do, petals drop cleanly. Height approx. 1m. There’s also a ‘Double Pink Knock Out’ on our list.

Flower Carpet – The first Flower Carpet® Rose was bred in 1988 and was one of the first to be marketed as a groundcover rose. ‘Flower Carpet Pink’ was introduced in Australia in 1991. It features small deep-pink double blooms produced in clusters throughout the season with arching, bushy and spreading growth (60cm tall and 1 to 2m wide) with glossy disease resistant foliage. In the past 30 years it has sold about 100 million plants worldwide.
Bees Paradise – A hardy and compact range of low growing shrub roses in Pink, Bi-colour, White and Red. These plants form a carpet of roses and are ideal for group planting, borders, rockeries and informal gardens. Deadheading is not essential.
ROSE GROWING ADVICE FOR SUMMER
Watering
Summer is all about the weather. Adelaide has experienced low rainfall for the past five months, almost 50% below average. Water your rose bushes deeply. In particular, pay attention to newly planted and potted roses which should not be allowed to “dry out”. Young, newly planted roses will benefit from alternate, fortnightly applications of Neutrog’s Liquid Seamungus and GoGo Juice as part of their watering regime.
The amount of sunshine is very high, averaging around 300 hours per month. The UV readings are often high to extreme and evaporation rates, due to heat and low humidity, are very high. The most important ingredient for roses in summer is water. Generally, established roses need an average of 20 to 30 litres of water for each rose per week. It is essential that a rose is well hydrated prior to expected heatwaves above 35°C on average. If severe heat is forecasted in the week ahead, you should increase the rate of watering to 30 to 40 litres per plant. If a rose dries out, it is difficult to get it to recover quickly. Deep watering weekly is far better than small amounts daily. It is recommended to apply the water in one weekly application or, at most, twice per week preferably early in the morning. These watering recommendations assume you have a substantial covering of mulch. Without mulch, you will need twice the volume of water per plant.
Mulch is vital
It is recommended that you top up your mulch now. Currently most soils are still moist and mulching will keep that moisture in the soil. A generous layer of mulch will help conserve water and prevent the soil and plants drying out rapidly, it can cool the surface by 5-10°C,breaks down to feed the root zone, enables good microbial activity in the soil and also helps to smother weeds.
Neutrog’s ‘Whoflungdung’ is an excellent mulch recommended by the Rose Society. It’s a certified organic mulch which is biologically activated, nutrient rich and weed free. It comes in 20kg compressed bales. Make sure the ground is well watered before you mulch. Spread a layer about 5cm in depth and water in to reduce odour and settle it down.
Removing Spent Flowers
To encourage repeat flowering, remove dead blooms. Generally, remove the old bloom and a portion of stem down to the second five-leaflet leaf. Occasionally, some ‘blind’ shoots don’t produce flowers and these can be trimmed to encourage a new shoot. A non-performing rose bush is a sign that it is lacking fertiliser or may be diseased.
Fertilising Your Roses
If old blooms were removed following the first spring flush, another flush will coincide with Christmas. Then there are two options. The first is to leave the spent blooms on the bush and reduce the watering a little, providing just enough to keep the plants alive, but not thriving – effectively placing them into a summer hibernation. They can then be stirred back into strong growth with an application of Neutrog’s ‘Sudden Impact for Roses’ and a summer trim in late February or early March.
‘Sudden Impact for Roses’ is an organic based fertiliser recommended by the Rose Society of S.A. It provides a full range of plant nutrients in a slow release pellet form together with water-soluble nutrients to maximise performance.
The second option is to keep the rose flowering with continuous removal of spent blooms, with plenty of water and applications of liquid ‘Sudden Impact for Roses’ every two weeks in January.
It is to be expected that the flowers in January, February and early March will generally be smaller with less petals compared to autumn flushes. This is heat related. In addition, due to high UV readings, dark coloured roses, such as red roses, can show scorched petals. Temporary shade can prevent this occurring if desired.
Pests and Diseases
Look out for Spider Mite which can appear when it is hot and dry. The lower leaves close to the ground may be pale in colour. Remove a leaf, turn it over and watch carefully (a magnifying glass may help). If insects, the size of pepper start moving around and/or a fine web is evident, Spider Mite are present. Organic oils (such as Eco-Oil or Eco-Neem)or one of the natural sprays (such as Natrasoap)can be used to control bad infestations – don’t use strong, toxic insecticides.
Water sprayed upward from under the leaves can also assist with the removal of early infections. Spider Mite live under leaves and don’t like to be wet.
