I recently completed building a house in NW Arkansas. We moved in in December and thus, completed the landscaping in January. Some of my azaleas look like they are struggling a little bit. They show new growth, but are not very full, and just don't look good. The ones that look the worst are planted on the south side of the house and the north side of the house in unprotected areas. The ones planted closer to the house and on the east side look awesome. My question is there anything i can do to get the azaleas looking better? The are not dead just struggling a bit.
