|Hi. Is it possible to keep outdoor trees such as Fraser's Photinia and Eunonymous K. Manhattan as indoor trees? If so, what kind of care would be required?
|I think you could grow both of these as houseplants, although their natural sizes are actually very large so you would need to prune them often to keep them at a manageable size. Luckily, both tolerate pruning very well. It is important to prune the photinia often while it is small to force it to branch near the base and thicken up, otherwise it will be very leggy.
You would want to provide ample light, good air circulation, keep the soil slightly moist but not sopping wet, and fertilize regularly during the growing season with a water soluble fertilizer for foliage plants according to the label instructions. Keep a careful watch for foliar problems so they can be treated immediately if they occur since both of these plants have some susceptibilities. On the euonymus watch particularly for scale and on the photinia watch for scale and leaf spot.
Good luck with your shrubs!
