RECENT NEWS 
Workshops:  In place of our regular meeting on July 3rd, BSA hosted guest speaker Mike Rogers with the BSF Speaker program on Tuesday July 16th.  We had a wonderful opportunity to learn from Mike and gain new knowledge on a variety of trees. You can reach Mike Rogers via email at the following: mike@mikerogersbonsaistudio.com
Mike began his presentation with some much appreciated information on “Azaleas in the South”
Azaleas in the south – most are multi-trunk trees – you want to be able to see each trunk.  There are many hybridized groups that include satsuki (which is better for the south), southern indica, formosa, Duc de Rohan (coral or white), Duchess of Cypress that are all breed for the southern climate.
What to do to minimize stress on satsuki,
1. Not accustomed to full sun, but best in full morning sun and afternoon shade.
2. Never use dirt in the soil mixture, use a combination of lava rock, haydite and crimson.  He does not use any organic matter in any of his soil mixtures for bonsai.  Organic matter causes a muck layer and no oxygen can get to the roots.  The roots will die from anaerobic bacteria.
3. Shallow pots are worse than deeper pots due to the “perched water table”, wherein about ½ inch of water remains in the pot.
4. Rake out roots, clean vigorously each and every pocket of old soil before putting in well drained soil mixture (see item #2)
5. They are bottom dominant and determinate for new shoots. In bonsai reduce the number of blooms so it continued to grow otherwise once it blooms it stops growing.  Don’t allow to bloom while in development stage. Once it is in a bonsai pot then allow buds to bloom.
6. They have specific roots for specific branches so if you cut back to close to the trunk, then the branch it feeds will die back deep into the trunk
7. Use clean tools, Mike’s mixture for tool cleaning is 50/50 liquid Lysol and water.
8. Between cutting azaleas, also use a box cutter blade so each cut is very clean, seal every cut, otherwise spores will get into cuts and kill branches. Never use a concave cutters on azalea, use a flush cut root cutter for example.
9. Use azalea fungicide “Subdue” which is very expensive, may consider less expensive items such as Daconil, or copper soap.
10. Leaf rot – rainy days or weeks, only water during the daytime, they do not do well when the leaves remain wet overnight.  The first sign of leaf rot is hanging brown leaves on the tree that do not fall off on their own.
11. Powdery mildew – leaves need to be dry before night fall.
12. Petal blight – it won’t kill the tree, just ruins the flower, which will just hang onto the tree and not fall off on its own
13. Prevention of leaf rot, powdery mildew, and petal blight – keep out of excess rain for several days
14. Once azaleas bloom for 2-3 weeks, pick all of the flowers and buds to reduce weakening the tree. Keep already fallen leaves and blooms off benches and out of soil mixture on pot to reduce the risk of fungal or other diseases
15. Once bloomed, cut back the hardest – repot at the end of Feb. or early March. The year you repot, do not allow the tree to bloom. Remove buds in the fall before your repotting in Feb or early March.  Repot every 3rd year if healthy tree, trim off 1 inch of outside and bottom of tree, put in a smaller pot. Azaleas seem to grow better in a slightly smaller pot. They only need small finer feeder roots while in a bonsai pot. Fertilize with Hollytone from Epsoma for acidic soils. 
16. avoid green moss as it can cause bark rot – instead, use sphagnum moss, run through or across a sieve or screening mesh, break it down into smaller particles, cover the top of the soil moisture, it will keep the soil from drying out after repotting and has antifungal, antibacterial properties.
Mike also discussed, gave style and design tips, pruned away aerial roots, and branches on several trees including BSA Members Dottie Burleigh and Vic Hebert’s Nerifolia, Bruce Broussard’s Ficus Root over Rock, Johnny Hardcastle’s Japanese Maple, Tim LeJeune’s Trident Maple, and Dario Billiot’s Ilex. Here are several of the photos taken during the workshop:
