Rosa 'Graham Thomas'

A deciduous upright busy vigorous growing shrub rose. Grows up to 1.5m tall and wide.

Glossy bright green foliage. Fragrant cupped fully double rich yellow flowers bloom from summer to autumn. The flower scent is a lovely fresh tea medium-strong fragrance with hints of violets.

Prefers full sun with fertile humus-rich, free-draining soils.

Always choose healthy well grown plants and plant after autumn rains as the soil is moist and warm and allows plants to become established before winter. This enables them to withstand dry periods during the following summer. Young plants require thorough watering during dry periods over the first two or three years. Mulching helps to conserve moisture and suppress weeds.

Before planting ensure the root ball is saturated and remove the planter bag or pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball and add in plenty of organic matter or compost to the hole. Place the plant in the hole but be careful not to plant too deep. The bud union of the plant should always be above the surface so plant at the same depth as it was in the pot firm in and water once planted. Make sure plants are watered well until established if planting in a drier period. Plant with some general slow release fertiliser and then every spring apply an organic based fertiliser such as blood and bone at a handful per square meter as new growth begins or mulch with well rotted manure. This will give the rose plenty of nutrients to establish itself quickly.

Roses may be bought as bare-root plants (not in a pot or with any soil around the roots) are available in winter and may be planted from June to early August.

Mulching annually helps suppress weeds and conserve moisture. Organic materials such as sawdust and bark contribute to soil structure as they decompose but keep mulching material away from the trunk.

The first summer and autumn after planting is critical for young plants; water thoroughly during dry periods. Pests and diseases can have serious debilitating effects on young plants; check regularly. A good rule of thumb is to give your roses one deep watering each week in dry times this will ensure the roots look for water themselves. Check stakes and ties for chafing and constriction and loosen if required as the plant grows.

As for feeding your roses, most varieties will do very well with a single feeding in early spring when the leaves start to bud. Since this rose is a repeat bloomer, you can feed them several times through the growing season to encourage additional blooms. Give a second feeding just as the first big bloom starts to develop and one more in the middle of the summer to promote later flushes. Use a quality fertiliser (preferably organic) which contains a balance of major nutrients (NPK) and trace elements. The fertiliser should be applied at least once a month or a small amount often with fortnightly applications of liquid seaweed over the foliage. Mulching with well rotted manure is an alternative.

Pruning roses is pretty easy and for the most part you are pruning for health and shape. Prune in June or July while the plants are dormant before the leaves open up as it will make it much easier to see what you are doing. 70% of the rose plant is normally pruned off but with shrub roses, this can be less if a larger plant is desired. Always start off by removing the dead wood, along with any canes that look diseased, any very old wood can be removed back to the crown, and the bush pruned to shape. Cut back any lateral canes that overlap one another once the leaves open up these overlapping canes will compete with one another for sunlight. Shape the rose to whatever general shape you desire but prune to outward facing buds.

Take the opportunity to also rake up dead leaves and debris from around the base of the plant as these can lead to pests and diseases like blackspot re-infecting your plant for the following season.

Deadhead regularly throughout the flowering period to help encourage more blooms.

Relatively pest and disease-free. Ensure plants are well spaced and regularly pruned to avoid powdery mildew. Aphids, glasshouse red spider mite, scale insects and rose leaf-rolling sawfly may be a problem.
