Rose

Meet the rose, the flower with the longest reputation in any garden and, in Dubai, the one that repays attention most visibly. A rose in a well-fed cool-season bed is a different plant from one left to fend for itself: glossy leaves, fragrant blooms, and new buds arriving one after another.

The surprise, according to a Jumeirah gardener profiled by Gulf News, is that heat itself is not what kills roses here. Hot air and the hot water that sits in irrigation pipes are. Her answer is to grow roses in pots, move them into the shade of bougainvillea for the summer, and water at dawn, when the pipe water is cooler.

From October to March the Dubai rose has an easier life, and that is the season to plant, feed and prune. Dubai Municipality's own nursery sells roses alongside petunias and marigolds, and UAE plant shops list potted roses for the garden.

Garden roses are thorny shrubs bred from the genus Rosa, and UF/IFAS groups them the way gardeners buy them: miniature roses for small spaces, climbing roses for trellises, shrub types and cutting varieties. Hybrid teas, the long-stemmed florist type, may need extra pampering, while tougher roses such as Rosa rugosa thrive in difficult conditions. In Dubai the type matters less than the care: how much sun, feed, water and summer shade a rose gets decides whether it flowers or sulks.

On sun and heat, UF/IFAS says roses need at least six hours of sunlight and frequent water and fertiliser to bloom their best, and the Jumeirah rose grower in Gulf News says five to six hours. She also says people are wrong to think heat will kill roses: the damage comes from hot air and from the hot water in irrigation pipes. In practice that means morning sun, afternoon shade in the hottest months, and watering at dawn.

On soil and water, the UAE's soils are dominantly sandy and infertile (ICBA), and a UAE gardening guide in The National notes that nutrients wash through the sand quickly. A rose bed therefore needs plenty of compost or manure mixed into the whole planting area, as UF/IFAS advises, and regular feeding afterwards. UF/IFAS places Rosa spp. in the moderate salt-tolerance group for South Florida, so salty irrigation water is a risk to watch rather than a certain killer: brown leaf tips are the sign, and a deep flush of clean water clears accumulated salt.
