Dying Trees
I have developed a problem. I have about 10 trees that have turned brown and are aparently dead or dying. I can't figure out whats happening. During the last 6 weeks or se we have had terrible rains on several occasions. I'm talking 10-20 inches non-stop twice just from the downgraded hurricanes that have came thru here.
The only other thing that comes to mind is that I sprayed a couplle weeks ago with some malathion to kill some webworms. The local feed and seed said that was the safest spray on the market. Could either of these things be the culprit or should I keep looking? None of these trees were woth shedding a tear over (all potensai) but i wanna stop this before i lose any more. I thank you for your help. |

Timeless,
A little more information would go a long way towards us being able to offer any advice or help. Could you tell us what type of trees are dying, the type of soil that they are planted in, how long they have been potted and your growing zone? Thank you, Will |

Hi Timeless,
It might be salt damage. Hurricanes pick up a lot of salt from the ocean and can deposit it in the rainfall that follows. You want to water the plants thoroughly with fresh water (flush them several times) and you might also consider sprinkling powdered gypsum (about half a teaspoon on small plants and a couple of teaspoons on larger ones) to help correct the soluble salt problem. Here's a link that talks about the effects of salt on plants (it happens to be about roadside plants that get hit with salt spray from de-icing but the mechanism is the same) http://www.extension.umn.edu/distri...ces/DD1413.html Good luck and let us know how it works out!

Thanks for that info TreeBay I would have never thought of that.
Will The affected plants thus far are Ficus Ben., Youpon Holly, A native myrtle These were all young plants 1-2 year range all repotted this year except for the Ficus which is approximatly 10 years old. The soil mixture is 40%pine bark--20%oil dry--20%#16 blasting sand and 20 % turface with a bit of crushed lava rock. Next repotting season I do plan to replace more of the pine bark as it seems to be breaking down too rapidly. I am borderline zone 8b-9a. Last edited by timeless : 30-Sep-2004 at 06:28 AM. |

Amazing Matt, I never would have thought of salt being deposited from the hurricanes, it makes perfect sense and I think you nailed it right on the head.
Timeless, Matt gave you excellent advice and your soil mix should be easily flushed, please keep us posted on your success. |

I live in the Bahamas. We have had two storms, back to back this year. The water I use for my trees comes from a rain water catchment. I have noticed that there is a bit of salt in the water after a very windy storm but not enough to bother my tress that are things like Seagrape, Ficus etc they don't mind a bit of salt. I live about 3/4 of a mile from the sea. But no one lives far from the sea here as the island is only seven miles wide at its widest point.
My bonsai, about forty of them, spent the storms safely tucked away in my sunroom - which is boarded up so they spent two or so days in darkness! They are moved in there at the very last minute before the storm and removed as quickly as possible after all danger has passed. That way they don't spend too long in a dark, airless room. It does not seem to hurt them.  A friend of mine, for some strange reason left his two trees out in the storm! For "safety" he tied them to a pole. The wind took all the leaves off! Broke the pots and all the soil was "cast to the winds!" After the storm we re-potted and new leaves budded the other day! Such is the resilience of the Tropicals!  |
