Re: what's killing my tree
Hard to tell from the pictures but it appears to lichen - Lichen - Wikipedia, the free encyclopedia
".....You are more likely to find lichens on unhealthy trees, but lichens are not the cause of the trees' deterioration. Lichens are related to mold and moss and grow well on trees suffering from other issues, because the plants are not healthy enough to fight them off. Lichens do little damage other than blocking some sunlight from getting to the tree, but you can remove them for aesthetic reasons." |

Re: what's killing my tree
I am no expert on lichen but I will say this, I have never known them to kill a tree or even hurt it in any way.so you might look for something else. What kind of tree are they. Looks like pear?Although the pear tree is an adaptable grower, some conditions are simply too hot or too cold for the pear tree. Warm winters can damage and, over time, kill a pear tree by preventing it from entering its dormant phase and leaving it weakened and open to attack from environmental and microbiological factors. Pear trees require between 41 and 50 consecutive days below 45 degrees Fahrenheit for an adequate dormant period. Grow a pear between U.S. Department of Agriculture hardiness zones 5 through 8 to prevent climate factors from killing your pear tree.

Re: what's killing my tree
Just tossing this in the mix .
Lichens are generally harmless and are epiphytic. I have lichens on some of the older trees and rocks in the yard which add visual interest.....but Wormfarmer your fruit trees have an issue. I see you still have tags on them you might be able to return them. Landscape CSI: Do lichens indicate impending tree death? - Science News - redOrbit |

Re: what's killing my tree
If indeed they are pear, I don't know about Florida but here we have issues with 'pear rust', a blight that can be caused by the nearby presence of juniper trees......if you have juniper trees in the area you are pretty much out of luck (we have ornamental pears, planted by the city, along the boulevard and every few years they have to be replaced - I keep asking them to plant something else)
Anyway, this rust causes orange welts/blisters to appear on the leaves. If the tree is young it is often not strong enough to survive for more than a couple of years. If the tree is older is can survive but is definitely weaker - the blisters can cover the leaves and rob the tree of its ability to photosynthesize properly Gymnosporangium sabinae - Wikipedia, the free encyclopedia |

Re: what's killing my tree
There's some kind of disease that attacks prunus trees up north but I don't know if it happens down here nor can I recall what it is. Can you take a branch to the extension service? They'd know for sure (or should) what's causing the decline and death. Perhaps a local master gardener could help?

Re: what's killing my tree
I think someone called it something with black in the name but the damage does seem very similar so I'll defer to you. It didn't kill immediately and pruning affected branches helped; nobody ever mentioned spraying. (Hey, not my trees so it wasn't my issue.)

Re: what's killing my tree
That sounds more like it! Nasty looking. I had an apricot that developed a huge wound in her trunk that oozed amber like material which eventually set. I assumed she'd die (which would have been fine because I hate apricots and grew it for the EX who decided he disliked them also) but instead she got taller and stronger yielding massive bushels of fruit.

Re: what's killing my tree
I will get more pictures soon! one of them is a low chill pear, low chill cherry and low chill peach. My low chill apple died this year. It also seems to be getting my blue berrys. I feel like all my trees are going to die. I'll get more pic. Typically all the new growth looks good.

Re: what's killing my tree
Oh, dear, not the blueberries! I have a potted Sunshine that's actually producing fruit so I hope you find out what's wrong and post it. Gardening in FL is definitely a challenge.

Re: what's killing my tree
Yes, says the highly lazy queen of mulch who loves it because there's less lawn to mow and no damaging plants by cutting near them, but that's not the main issue from what I see. I'm totally clueless as to what is causing the problem but really hope someone diagnoses it for you. It may be too late for your poor plants; I hope not.

Re: what's killing my tree
Do you weed whack around the base of your trees (or have a lawn service that does)?
Send those photos and description of trees & damage to our AG dept and see what they suggest. DM |

Re: what's killing my tree
I do have a Landscaper. But he does not pull my weeds in the plant beds. I need someone to come over a clean up all this over grown problem I am having. I do need new mulch to cover the area around the trees again. I don't have a truck access anymore so it makes things MUCH harder.
I will try to find more info on the local AG department. Someone told me they would come out for free and try to figure this out. I am most worried about loosing my peach! It was my first "Hardwood" fruit tree, iv had it for 5 - 7 years now. It has a great looking trunk. Thank you everyone! |
