For some reason, my front of house pics did not show up in my original post. I'm a newbie at this...can you tell?;-)

Your window boxes are unquestionably too small to be really useful. They would dry out 3x/day. And they're mounted too high so that if something grey in them, it would block too much window. In most cases, it would be better to put a shrub in the ground below the window and treat it as if it were the window box plant.

I would definitely NOT replace a concrete stoop that was in good condition with a wood stoop. This would be a downgrade. If the stoop needs a better surface, there are many treatments that you can do to concrete in order to improve their appearance.

The entrance is presently tucked back and smothered by large shrubs. I'd get those out of there. The light colored one looks like it could become a small tree. You might move it over to an island next to drive, outside of the walk, and let it be a small sheltering tree, with groundcover below, marking the beginning of the entrance path. I think your walk definitely needs to be redone. Make it more spacious at the stoop (taking it all the way to the wall) and bring its path farther out from the house so that you have space for decent landscaping. I think I see a window behind the large shrub. If that's the case, THERE is where a GOOD SIZE window box would make sense (as concrete walk below it & no room for planting in ground.)

I can't say as I really like Hosta as the MAIN foundation plant. There need to be some permanent shrubs and let Hosta or other perennials fill in the gaps between those shrubs. A way of adding some interest to the picture is to place a good size, perfectly circular bed below the large tree, filled solid with groundcover. That'd be a great place for Hosta. Such a bed could be integrated with the foundation bed (which needs to be deeper.) Work out a bed layout in PLAN view in order to know how much room you really have for it and in order to get the geometry correct.

Thank you very much for your excellent feedback. Yes, the window boxes need constant watering and when flowers bloom you definitely see them from the inside! The light color shrub is a dogwood which I like but it is too big for the location. Do you think a dogwood would still work in the location you recommend? The window behind is a high rectangular window so probably too high for a window box. Maybe a tall potted something would work there? Thank you very much!

some ideas:

I like your ideas very much! Thank you! Are you suggesting keeping the window boxes, just bigger and lower?

The window boxes can stay. If you use plants that tolerate dry soil like verbena, portulaca, sedums, etc, you should not have a problem.

Thank you Dig Doug and Yardvaark! We typically plant impatiens in the window boxes and water daily a.m. and p.m. Not to take advantage of your skills but I would welcome ideas for improving the back side of the house too. I should have posted a better picture and can later today if you want. There is a large picture window to the right of the screen porch and a square brick patio to the left with a brick sidewalk along the garage wall to the driveway. Straight lines, nothing fancy. The large bush on the right side of screen porch is a Japanese lilac. I know it is large but it provides privacy which we like. Thanks again!

Ideas for the rear of the home:

Magic! Love it. Would really tie the front and back together nicely. Thank you!

Thank you. I like the wood doors! So shutters and window boxes are not a good idea for this style house?

I don’t personally care for the window boxes, even if you get right-sized ones. Phun’s wood doors and the clean lines (open and wide stoop and sidewalk) on the front look great and are appropriate for a ranch style house. I like the matching planters too.
