Description

This award-winning upright evergreen shrub is one of the very best of its kind for showiness and intense crimson colour. In spring and summer Rhododendron 'Lord Roberts' grows trusses of large, funnel-shaped flowers in a magnificent shade of red with dark red/black speckles. Forming a dense and bushy upright habit, its evergreen foliage, which is thick and glossy, creates year-round interest and makes Rhododendron 'Lord Roberts' an ideal choice of hedge or screen. It also makes an excellent specimen plant.

Considered one of the toughest and hardiest Rhododendron available, 'Lord Roberts' prefers a sheltered and partially shaded position, as well as an acidic and moist well-draining soil type. Will reach an approximate height and spread of 2 x 2 metres in 20 years.

Planting Steps

1Preparation

Pot-grown plants can be planted at any time of year, whereas bare roots need to be planted between November and March.
Clear weeds and grass within a metre of the planting hole.
Dig a hole as deep as the root mass and twice as wide.
To help your plant establish more effectively, sprinkle Rootgrow in the hole.

2Planting

Gently loosen the roots and place into the planting hole.
Ensure the top of the plant's compost is flush with the level of the surrounding soil and the graft union or collar of the tree is above ground level.
Mix 50% of the original soil with 50% compost.
Fill in the hole, firming the soil gently.

3Last Steps

Water generously around the base of the plant.
If you are planting either a single stem tree or mature standard tree, we recommend adding a staking kit and rabbit guard.

Aftercare Advice

Rhododendron and Azalea are generally low maintenance however they will require a good watering regime for a couple of years whilst they establish. Water well and regularly through spring and summer, increasing in hot or dry weather. If planting in autumn, you may only need to water a little. Rainwater is preferred but tap water can also be used. It is advisable to keep the area free of competing weeds and grass during this period.

Rhododendron and Azalea are acid-loving plants so when grown in acidic soil are unlikely to need additional feeding. However, if the acidity of your soil is low, iron, manganese and magnesium treatments can be added to prevent browning and yellowing of the leaves. Potted Rhododendron and Azalea may also benefit from a slow-release granular fertiliser which provides an on-going support of nutrients.

Most Rhododendron and Azalea belong to RHS 'Pruning Group 8,' meaning they require minimal pruning. After they finish flowering, you should remove any deadheads and address any diseased or damaged branches, but otherwise, they should be left unpruned.
