    From what I understand, these shrubs have a fairly heavy, or extensive, root system so it is possible that they could be interfering with your foundation but only if they were planted within 5 ft. or less of your home. If they are diseased, it is likely from a fungus, which is common in these shrubs. While treatment is possible, I would recommend transplanting them elsewhere if your foundation is being affected by the roots.

    I would first try treating the fungus issue so they are somewhat healthy prior to moving. You might also need to prune them back by about a third. These articles will help: https://www.gardeningknowhow.com/ornamental/shrubs/photinia/photinia-leaf-spot.htm

    For red tip photinias, feed them a balanced fertilizer and one that is aimed at acid-loving plants. An even fertilizer like 8-8-8 would be good. Fertilize once in spring and once in early fall.

    Fall planting is usually better in warmer climates, while spring planting is a good idea in colder regions. The shrubs should be spaced 3-4 feet apart.

    Rooting the cuttings is much easier. As long as the stem you are cutting is healthy, you should not have any problems propagating it. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/shrubs/photinia/growing-red-tip-photinia.htm

    Sow seed in a cold frame in fall, or root semi-ripe cuttings in early summer using bottom heat. Most gardeners find it easier to root cuttings than to propagate by seed

    Newly planted trees and shrubs usually don't start rapid growth immediately, they need time to acclimate and become established. I would wait until next spring before trimming them for the first time.
