Florida Green Roofs - Know Thy Plants!

Florida summertime is hard on green roofs.  Not only are roofing membranes subject to intense weather challenges, green roof plants also are subject to intense biological and meteorological assaults.
Summer humidity may quickly kill Florida green roof succulents
We have posted notes about Black Rot fungus before here on this blog.  It never fails though that every summer persons will contact me asking why their succulents are turning brown, black or rotting.
Florida green roof succulents battle the Black Rot fungus every summer
The simple answer is to use Florida native plants (preferably evergreen species but a mix of deciduous plants will work too, depending on the green roof location in the state).  Here in Florida native green roof plants usually far outperform horticultural succulents.
Florida green roof succulents rarely become the dominant green roof plant and usually die out
Florida summers bring maximum humidity and maximum temperatures.  With daily afternoon rain showers most rooftops become pressure cookers, steaming green roof plants like vegetables in a hot wok.  If you do not intimately understand Florida roofs and how plants preform there (and this only comes from hands on learning, failures and successes are the best teachers) then your roof design may quickly end up devoid of plants as you stand there, helpless, watching the succulents literally dissolve in the heat and humidity and fungus attacks.

Tropical green roofs are a challenge.  We have listed some great green roof native plants here.

Know how your plants will perform in a pressure cooker before specifying them on a green roof here in Florida.

Why Florida Green Roofs Are So Environmentally Important

Here in Florida surface water can directly flow into the drinking aquifer below the ground in many places.  Here is a video of storm water flowing down into the ground through a karst connection to underground caverns after a recent rainfall event.
Cleaning rainfall runoff with green roofs and other urban greening projects before the stormwater reaches our drinking water supplies makes good sense.

Avoidance of pesticides, herbicides and lawn fertilizers and chemicals is good not only for our environment but also supports a cleaner and healthier place to live in.

Connective Tissue Challenges, Learning to Live All Over Again

Someone started a rumor long ago that says you can't teach an old dog new tricks.  I say, "it depends on if they have a connective tissue disorder and how bad that dog wants to live".

Living with a dissected aorta - my descending dissection #Marfan
My present mission is to stay alive at least long enough to see my two teens able to support themselves and to enjoy life with my wife, Judy. That is pretty significant incentive.  I sure hope this is possible but I have to be honest and say that each day I wonder if I am going to be able to make it or not.  There are so many common, every day things that can seemingly push me towards the final edge.  

Living with a dissected root to foot and up into my kidneys, aorta and a HUGE false lumen that floats around inside the main blood vessel, requires me not to strain, lift or otherwise exert myself.  Surprisingly this is much harder than it sounds.  You'd think, OK, just don't lift or strain too much.  Yeah, right.  Open this peanut butter jar for me.

It is not the hour long weight lifting outings or intense home remodeling or green roof construction activities that I've already given up that present those unexpected aneurysm dangers.  Rather, it is the little things in everyday life that I have the most problems with.  Unfortunately I don't find out about just how I am hurting myself until after the fact and my chest starts becoming tight and my aorta begins hurting again.

After living with a Dacron graft and St. Jude valve for two and a half years I am still learning new tricks.  This dog has finally come to realize that there is no going back to the old way of type A living.  Today's life is centered around measured movements, cautious exertions, decreased activity duration and cardio instead of anabolic muscle approaches to exercise.

Tightness, aching and jaw, chest and back hurt are all still fresh memories haunting everyday life.  I never again want to experience the unzipping feeling radiating down my body as the intima wall separated from the other two aortic layers.  Today, I have very similar pain events occur out of the blue, though nowhere near as intense, whenever I put stress on my cardiovascular system.  So I have to learn to avoid cardiovascular stress of any type.

But these 'instigating events' sometimes are activities one would never expect to be potentially responsible for a future dissection or aneurysm.  Simple stuff, like taking the garbage out or moving a piece of furniture (hey dollies were invented for a reason).

Today I know I can no longer jump up from the couch and hoot or holler when a sports game is on television.  In fact, after the last few college football seasons and the Florida Gator's not so stellar performance (but hey, Go Noles!), I do not even turn on the television to watch games.  In fact I do not turn on the television at all.  There goes a bunch of cardiovascular stress out the door.  Now I blog.  New trick.

Today I must watch myself when sneezing or straining on the toilet.  Too many people have kicked the bucket on the loo; even some very famous people.  Thanks to daily organic psyllium fiber all things run much more smoothly now.  Yet the sneezing can't be avoided.  I just hold my chest tight when sneezing though I am sure that clasping my chest tight is not going to hold my pulsating internal supply hose together if the sneeze is big enough.  

Today I can't work on my bike like I used to be able too.  One of my pedals needed replacing and as I tried to loosen the proper bolt with an open ended wrench I felt that old familiar pain returning.  Stop, take a deep breath and think.  I must learn new tricks.  I can not strain like I used to.  My teenage son though can help me and the use of cheater bars and levers can make the job much less stress intensive.

Today I can not jerk on weed eater or lawn mower starter handles.  Upper body rapid upper chest movements while straining are a trigger for dissection according to Dr. Lars Svensson.  But this old dog here has found that today's electric weed eaters and lawnmowers are, especially with their 56V batteries, amazingly capable, lightweight yard machines and best of all they just require a button's push.

No more working on the car, but it is time for the teen son to learn anyhow.

Those darn random firing red-light camera flashes used to send adrenaline surging through my body causing the blood pressure to soar when I was driving.  Now, without a driver license I don't have to worry about keeping my eyes on the road.  No more gripping the wheel so hard the veins on my neck stand out.  No more yelling un-intelligible, sloberish words out the car window and hitting my head on the frame as I offer up evil hand gestures.  Much less stressful to walk or ride a bike.

No more scuba diving into caves.  Sometimes I wonder about the summer before I dissected.  I was diving in a tiny vertical cave shaft well over one hundred feet below the surface with hardly any room to even turn around.  Or those times I would free dive down into the west sink in Promise Sink, swim through the connecting cavern about forty feet down and come back up in the adjoining east spring.  Or those times in Peacock Springs where we'd dive straight down through fifty feet of zero visibility algae blooms to finally break out into a crystal clear basin full of alligators resting on the bottom of the cave opening.  What a rush!  And my aorta held.  Lucky I did not dissect underwater.  Today I lay on the beach and watch flocks of prehistoric pelicans glide seemingly motionless overhead, a much easier cardiovascular activity than equalizing pressure in one's head underwater or becoming tangled up with a dive partner scrambling away from large underwater reptiles.

No more eighty pound bags of cement.  No more forty pound bags of compost.  No more ten pound bags of ice.  Doctor says two pounds max.  Ugh, this is a challenge.

But the cheater bars (a long hollow piece of metal used to gain leverage - not a place to find alcoholic beverages or wild women), levers and teen help works.  The teen's echo shows dilation has started though, so the teen help will be limited and cautiously monitored.  This old dog is learning some new strategy.  Will it be enough to keep me alive?  I think where there is a will there may be a new trick.  

Connective tissue challenges might cause all sorts of hullabaloo but they also present all kinds of opportunities for learning to be creative.
