How much water do red tip photinia need?
They need regular watering but they can't tolerate wet soil, so make sure it is well draining.

I planted this red robin tree two weeks ago and the leaves are all drooping, I used multi compost with John Innis and some fertiliser
Part of it is the transplant shock, but it also may have gotten hit with too much fertilizer. Since you planted with compost that should have been sufficient for a while. I would have held out fertilizer till next spring. You didn't say how much fertilizer you added but it may not hurt to add in a little topsoil or unfertilized potting soil to dilute its effect.

It could be too much water and fertilizer. They don't like wet soil. This article should help:

eaves. Types are one Red Robin and 2 Pink Marble. Could it be lack of feed? We have fed them once with miracle grow. Bonemeal was used in the planting. Do they need more. When if ever should we clip them for shape. Thank you

I am getting photinia plants installed . They are 30 gal bushes almost 6 ft , without asking me , the installers pruned them up about 18 in. I need to know if , with the new growth , it will also grow back I ( like the density) I know they can grow 12 -24 in in a year so does that include the parts that are pruned ?
They should be fine and continue to grow. They need to be pruned to allow air circulation. Too much density can lead to fungal disease.

40 years of growth. Privacy shrubbery
Yes, they are pretty resilient and should come back. They can even be rejuvenated by cutting back to 6 inches from the ground.
If you live in an area where photinia leaf spot is prevalent, it's best not to prune until the dry, dormant period. The disease favors tender, new growth.
