Post a picture of the flower bed. I will try and give ideas that could help. I have grown moss in all compass directions. Think Kyoto Moss Gardens! That garden grows moss everywhere. Although Moss likes cool temperatures (cooler than most plants) The fact is the stuff will even grow in full sun. The conditions need to be livable. Yes, you can feed moss. My favorite item in decomposed leaf mold and decomposed and ground up pine bark. Peat moss that you buy by the bail is great for a soil conditioner. What a better food additive than the components of moss! Some people make Sphagnum tea to water with. My first Bonsai garden had an southern exposure. The moss I grew was for sale. The trick was the Mister system I put in and the fact the area did not get sun all day. It will be hard to believe but the area received full sun from 10am to 2pm. The area grew moss like a weed. If the sun does not stay on this plant too long, "Brunnera, Siberian Bugloss", it is a great item for a shaded area. Stick with the solid green leaves. If the plant isn't in moist soil and the sun hits the leaves it will "burn" like a vampire! If this will grow the light for moss is great. The best way to grow moss is collect all the information from all sources. Then look at your conditions and adjust them if needed. I added a mister system. I also put up a small shade cloth to cool the air. It did not shade the plants but kept the hot sun from bouncing off my house and heating up the area. I know this is long winded but I couldn't get moss to grow worth anything and now my biggest obstacle is the squirrels! They love my moss to make their nest with.

You can always remove the dead portions of a plant. Any part that is brown or crisp should get cut back to healthy growth. It is debateable if you should remove the sunburnt or cosmetically damaged portions, but you can so long as the plant still has enough leaf surface to survive. I tend to leave most of the damaged areas until the plant has adjusted to my conditions - sometimes the damaged portions dry up and can be removed all on their own. Joe 'YMMV' DeRosa

Azaleas like acidic soil & would probably benefit with filtered light or morning light, but not necessarily. Mine gets decent light before the trees leaf out, but after that it's in mostly shade & does wonderfully. I do add acidic fertilizer every 3 months to help & water well.

I LOVE Beautyberry! We bought this property 18 mos. ago & we have SEVEN! They're natives, and you can pretty much prune them any time without hurting the plant (but if you prune them now, you'll lose those berries.) OK, so you lose a few branches of berries to keep the plant looking nice. . . . What I do for shaping is during the winter, after they've lost all their leaves, I HACK them back to about 3 ft. in the center and tapered down to about 1 ft. on the outer perimeter.
