ROSE Rosa ssp. (ROSACEAE)

Plenty of species and cultivars commercially used as cut flowers.

Uses
Rose production is driven largely by seasonal demand to supply Valentine´s day, Mother's day etc. Producers deliver their products within a 5-day window of time and the growth must be timed precisely through careful control of heating and cooling. For this reason, most cut roses are grown in greenhouses; typical commercial-scale production scheme is planting in hedgerows. Types of growing media vary. Traditional media are native soil and potting mixes. Some growers are using hydroponic systems with the use of coconut coir, clay pellets, or rockwool.
Ecology and planting
Roses need 6 or 10 hours of direct sun each day. Morning sun is essential, but light afternoon shade is tolerated and even beneficial in hot climates. Good air movement helps the dew and rain to dry quickly, thus discouraging disease. Bare roots or potted roses are usually planted In containers with required effective drainage at the bottom. The planting medium for containers should be rich and well drained. Pruning controls the size and shape of roses and keeps the modern varieties blooming repeatedly. Economic life of the plantation is 5-7 years.
Mycorrhiza & Bio-fertilizers
Roses are plants with high dependency on mycorrhiza. Commercial production testing of the effect of inoculation proved that roses treated with mycorrhiza grown in hydroponics show 10-15 % higher numbers of flowering stems, some rose cultivars showed 5% increase in bud size after treatment. Mycorrhiza reduces negative effects of root pathogens and we may expect prolonged peak production time (when mother plants produce good yield of flowers) by at least one season. Combined mycorrhiza and biofertilizer treatment reduces the need of fertilizer application by 50% within the first two years after planting .
