leaf node toleave a 8cm / 3in cutting. The cutting should be semi-ripe whichmeans not new soft growth and neither hard old growth. Somewhere inbetween is best.
A single Red Robin will grow very happily in a large container. A diameter of 45cm or more is about right. However, in the colder parts of the country, especially in winter, it would be wise to avoid northern exposure and keep them in a sheltered spot. Our suggested routine would be an annual prune in early to mid June when the flowers are dead or dying down. If you prune at this time of year you will be likely to have flowers again the next year.In all likelihood your Photinia will not be the only shrub affected, although Photinias are particularly susceptible. We suggest you research this disease online / in books because it is extremely difficult to eradicate. Often the only course of action is to dig up and burn the affected shrubs and plant those which are resistant to honey fungus. HOW AND WHEN TO PROPAGATE RED ROBINS In general, most photinia varieties are planted in open ground where they serve as decorative bushes, hedges and screens. Take the cuttings in late July to early September time. If the bushis some distance away take a plastic bag to store the cuttings in andprevent moisture loss. Also, take the cutting longer than needed andmake the final cut (see below) when you are ready to plant the cutting.This will minimise the cut healing over which makes rooting moredifficult.
If the soil is heavy or is not free draining addlots of well rotted compost to the area and dig it in well.
Robin Planter
It depends on the variety, as while several varieties attain manageable sizes of up to 2m in height and about 1.5m in spread, several other varieties grow to over 5m and some of these have a fast growth rate to boot. An evergreen shrub which, if not pruned, reaches a height of 4m /13ft with a similar spread. Red Robin grows at a rate of about 30cm /1ft per year when established. It responds very well to pruning and caneasily be kept to a height 1.2m / 4ft.
If you opt to grow a largeish, spreading variety in a container, a planter would be very suitable. Compost Requirements Firstly, the container should be large enough to accommodate your photinia variety at its given stage of maturity. When established a Photinia Red Robin will look after itself. It rarelyneeds watering except in severe drought and will grow quite happily onaverage ground without the need of additional feeds. It will need pruningonce or twice a year to keep it in shape and to size.However, if you use a wide enough planter, you may plant 2 or more of the more reasonably-sized varieties in it to create a containerised decorative hedge. Potted Photinia Care Most cultivars put out young leaves that are in shades of pink and red while a minority have coppery, bronze, marbled or cream-edged foliage. It is fully hardy in almost all areas of the UK withstandingtemperatures down to -12°C. In protected position, it is hardy to afew degrees lower. See the comments question / answer section (comment datedApril 2018) at the end of this article if your Red Robin has lost many of itsleaves during a particularly cold winter. Prepare a mix of garden soil with added grit combined with organic compost and well-rotted manure and blend the two mixes in approximately a 7:3 ratio.
During that time keep the rooted cuttings in a cold greenhouse or outsidein a shaded position out of the way of harsh weather. They may well needwatering, keep the compost slightly moist but not waterlogged. The cuttings should begin to root in two to three weeks and at this pointremove the plastic bag. The cuttings should then grow and the best time toplant them out in their final position is next April / May when the dangerof frost has passed. Dogs Trust does not list Photinia Red Robin as being poisonous to dogs. The are indications however that it can cause problems with grazing animals such as horses and cows.
