Gardening/Landscaping: Planting Trees, Flowers, and Shrubs

AZALEAS

Spring is approaching and my green thumb is itching. I built a deck about 2 years ago and on the back side i want to plant some Azalea bushes. I want large azaleas that are hearty and beautiful. Want to plant 2 different types, and alternate their locations. Definitely want to go with Formosa for 1, but can't decide on the other. What i want to do is plant Formosa, other azalea, formosa, other azalea, etc... I'll probably only be able to plant 5 or 6. Is there a white variety that grows as well as formosa?
Also, looking here lsuag center azalea and it suggests

quote:

---

Select a partial-sun to partial-shade location. This area can have 4-6 hours of direct sun daily. Avoid late afternoon sun, especially in the summer months.

My backyard gets mostly afternoon sun. Behind the deck, i would say the azalea's would get most of the sun from 1-5. Is this a big problem?
Also, what is suggested spacing for your standard (not dwarf) Azalea bush? I was thinking 4-5 feet.

TREES

I also want to plant a tree or 2. Was thinking of planting a Mayhaw and was curious of how well they grow, and the conditions for growing them. Not much information from lsu ag center on growing mayhaws that i could find.

Also, my fig tree looks pretty bad. I planted it 3 years ago and its very small, and i only got 1 fig last year, after getting a good crop the year before considering the size. Last year, it looked as if half the tree was dead, as only 1/2 of the tree grew leaves. I've heard that last year was a bad year for growing most anything, so wondering if i should just dig it up and replace it or hope it comes back this year.

I'm also having troubles with my satsuma tree i planted september 2014. Not growing much and no fruit. I had some small satsumas growing in spring/summer. They were tiny and green, but a strong wind blew them all off. Suggestions for those would be helpful.
