Answer: Olive tree loses bark

Good morning Fausto and thank you for choosing our website and its question and answer service once again. The olive tree is a plant perfectly adapted to the Mediterranean climate, cultivated practically throughout the coastal area of ​​the peninsula and also in the innermost areas where the climate is milder, such as near lakes.

A very frequent mistake that is made with the olive tree, a mistake we have already talked about several times on our site, is planting this plant too low in relation to the ground. The olive tree is a plant that must be planted high because it suffers very strongly from soil moisture and water stagnation in the collar area. Often it is enough to have planted the olive tree even a few centimeters too low to have negative effects on the health of the plant. The olive tree can begin to lose its leaves, to lose pieces of bark from the stem, in short, to visibly lose vigor just because it has been planted too low.

Planting an olive tree with a high collar is also important because the transplantation of individuals having a certain number of years is always a risky operation that is recovered from the plant in a rather long period and therefore it is always better to carry out this operation as few as possible. times possible.

The operation that we advise you to do therefore, if your olive tree has actually been planted too low, is to replant the plant but this time keeping it with the collar higher than the ground level. This surgery should solve his problems.

Olive tree loses bark - garden

from the description it seems to have been the cold.

I have no doubt that my olive tree has caught cold, but I assure you that:

1- I didn't buy a centenary olive tree in Puglia but a modest one
2-3 years old seedling in the nursery about 8 years ago.

2- have you ever been to Lake Garda? Try to visit it and you will find
many olive groves and related olive and oil culture in the area. It sure won't be
comparable to that of other areas.

What Monica says is true, what You say about that is also true
which concerns Lake Garda, on those slopes the climate is milder.

As for your olive tree if the low temperatures have
abruptly exceeded 0 degrees C there is a risk that cellular water
have ice cream and then goodbye plant. Or it may have triggered
the supercooling mechanism for which some olive tissues
they manage not to freeze up to -15 ° C the leaves are part of the organs
which do not resist freezing while mechanical fabrics tess.xilematici
and gems yes.
If I were to notice the detachment of the cortex then that is the symptom
more serious than a possible desiccation.

Leccino and Frantoio are the most resistant cultivars to low temperatures.

Let us know, the days are getting longer (photoperiod) and so are the
temperatures.

for the moment leave this way, at the beginning of the vegetative restart remove the
suckers from the center of the plant and possibly the twigs that are there
annoyed.

Hi, I have a potted olive tree. I am watering it with a timer sprinkler activated every 8 hours for one minute with drop of water drop by drop in a pot of about 40cm in diameter x 50cm ... for some time I have noticed that the leaves become lighter only for a third of leaf (the one towards the tip).

Good morning. two years ago we made oil with olives harvested from our eight olive trees. For us it was a great success. This year they were perfect until a few days ago: now they are sick, they curl up, there is a large quantity of fly. We thought the yellow signs would save us from this problem. The oil mill we know, here near Genoa, opens only after October 15th. They will all be thrown away! I don't think it will be possible to choose them one x one! besides in a week it will be too late. We should have collected them first.

good morning Carla. I also use traps for the olive fly. based on my modest experience the advice I give you is that when you start to see the flies in the yellow card (trap x flies) if you want to collect olives you have to start doing treatments with specific medicines I count the moscadelle olives respecting the deadlines I greet you and I hope I have been of help bye

IN Spring year lost many leaves and
now the fruit is turning black and
falls is all sick.
What can I do? Yours sincerely Thanks

hi I wanted to know how I can cure an olive tree that is drying up all the bark falls

Good morning
I have about thirty olive trees, this year I collected the olives and, since the mill is slow to press me, I placed them in a ventilated area on sheets.
despite this I noticed that under the olives there are worms resembling small grains of rice.
someone can tell me if they are still good to squeeze or should I throw them away?
thank you

I also picked my olives and there are small worms in the shape of a grain of rice. What needs to be done so that it does not reappear again next year

hi, I have about ten olive trees and they are all full as if they had mange, the fruit is very small and hard to drop and the oil is also bitter. I do not do chemical treatments only pruning, I need your advice, thank you, I wait for an answer .... hello

Hi, I have about ten olive trees in pots and some of them for a few months seem to have been affected by cyclonium: the leaves dry up and fall off. The strange thing I noticed, however, is that the leaf is half dry and there is no characteristic peacock eye shape. So what happens to the plants? I look confident in your advice. Sincerely

if there is the possibility of knowing what they are, certain protuberances (resembling leeks, present in multitude above the branches of the olive tree, thanks for your kind cooperation.

hi I have an olive tree where the woodworms have settled… .. I pruned the whole plant until it was almost cut off, as I was told at the consortium…. but the olive tree no longer sprouts ... .. it needs to be planted, what should I do. thank you

hi my name is max I moved an olive tree about 4 years old but a few days later the leaves turned black. what should I do

It is fumagine ... fumagine and a set of fungi that go to undermine the honeydew of insects (excrements that stain the plant with a sticky substance) or even in the case of strong nitrogen fertilizations ... the best thing you can do to eliminate the the problem is to take the Marseille soap (that hard tile to be clear) you throw it about a pound on 15 liters of hot water you dissolve it well once it has cooled down by means of a verdigris machine wash the plant ... The more you make it drip of soapy water the better and you will see that the fumage will disappear after which a nice cupric treatment on the leaves

On the branches of my olive tree (on Lake Garda) some ... how to say ... FORUNCOLI have recently appeared, they are like a hemisphere, as big as the tip of a female little finger. It seems to me that they weren't there before. what can it be? Thank you. Luigino

Hello, I planted a young plant, white "parasites" appeared near the flowers, so I think, slimy and gelatinous. I can find out what they are and if they are harmful and eliminate them.

hello I would like to know why the olive tree that I have been away from home for more than 6 years and it was already big when I planted it is drying up some branches from the tip .. what disease can it be and what product should I use?

Difficult to say, the best thing you can do, however, is to remove the dry tips, treat with copper and make a nice fertilization with urea in order to favor new vegetation ... to fertilize and if you do not want to burn your garden I advise you to drill holes in more or less one meter from the stem on the circumference of the plant 40 cm deep

I have an olive tree plant purchased at the supermarket in a vAso on the balcony on the 5th floor: the afternoon is very sunny. It is the second year and it has grown well, it had some flowers in the spring but none of the fruit. Now I have noticed that the tips of the various branches are "eaten" and dry: I have not noticed any parasitic animals.
Can anyone give me information and advice for remedies?

Good morning.
I want to know what causes a long black stripe on the trunk of the olive tree, which also moistens the bark. Looking at it, it looks like it was burned by a small fire or as if it were black smoke, but it has nothing to do with it.

It can be wood cancer in these cases you have to remove the affected part until you get to the clean part which will then be protected with mastic from grafts

i have olive trees and i have noticed that some plants are invaded by leeks. what can i do to fight it? And what is this type of plant disease called.

Leeks? Wood ball species? If so it is olive tree mange which is a bacterium that enters from the wounds ... the wounds can be caused by hailstorms or mechanical organs (pruning, milling, olive harvesting) so the only thing you can do is to leave the plants affected by mange both to collect the olives and to prune them then by pruning remove as much as possible of the affected part and burn it where it is not possible to do so (if they were present on the stem or main branches) remove the mange ball clean the affected part mange by bringing the wood back clean and then disinfect the cut with graft mastic or copper oxychloride diluted in poka water and apply it with a brush ... Then remember that every vote that is hailed or you finish picking olives or pruning treats with of the copper I recommend the blue copper of the timac 150 ml for 100 lt

Hello,
I live in Tuscany and my family owns an olive grove. In the last harvest, for reasons of time, we had to leave two olive trees. Last week walking among the olive trees, I saw that the remaining olives were still nice, firm and well attached, to which I thought of collecting them and putting them in salt and then putting them in the oven and keeping them in oil.After a couple of days that they were in the basket with the coarse salt, I found the worms underneath. olives are still there that slowly throw out the worms. Do I have to throw everything away? I read that they are not synonymous with dirt because they feed on the pulp that is healthy. But even the thought of eating them makes me a little sense ... .. Give me some advice.The olives I made in November were so good.
Thank you

Throw them away ... the olives that are not intact are impossible to keep the worm eats and the process of rotting begins so if you care about your health ...

Hello
I have 26 olive trees and someone took the whim (I don't know how) to make them dry by blowing a bit of bark into the trunk and I don't know if they put any medicine
I would like to save these olive trees
how can I do?
who can i contact?

Good morning,
in spring I bought a small olive tree in a pot that is giving me a lot of satisfaction, in fact it has flowered and has held 10 olives that are growing and maturing. For a few days, however, I have noticed that the new leaves, from the tip to the middle are becoming lighter almost "latte" and tend to fall. I don't want him to die, help me. Thank you. Monica

Good morning
I kindly ask to know the remedy for olive trees with tuberculosis, we have hundreds of olive trees with this disease (in Algeria) they tell me that it is a contagious disease and that I must eliminate and burn all the trees
Thanks in advance
Yours sincerely
G. Mohsen

I have the bark of an olive tree that was scratched with the nails by a cat or more, now a white fungus with a texture like rubber has formed on the main branches, and then cracks have formed in different parts of the plant, then I noticed that there are also very small snails planted inside the bark, almost not to be seen, not knowing how to solve the problem I used soap and water as a disinfectant, but I have not solved the problem, therefore I kindly ask the solution from your experience what can I to do to overcome this problem. Thank you, I look forward to hearing from you… ..

answer x all.
contact the order of agronomists and ask why in recent years they have dedicated themselves to other tasks instead of training valid technicians in the area who can have satisfaction after years of study and help the community in these and other problems that are serious in themselves but if neglected they can become tragic for the economy of the sector.
provided that they will deign to answer you.

I have a small olive tree for a few months and for a few weeks it is losing the leaves that are half dry, I would be sorry to lose it, what can it be? Thanks

I need some advice .. I have some olive trees that peels off the bark as if they were dry. What can I do to him? can they be cured? with what??

About the sick olive trees of Puglia. Since it seems that evil "prefers" old olive trees with trunks rich in old bark flakes where insects can easily nest to lay larvae. What would happen if these "voids" were filled with milk of lime and nothing else? Could pesticide producers be angry given the low cost of lime?
HAPPY 2014!

Almost three months after my previous message, I allow myself to come back to find out from those who live in the area of ​​the sick olive trees the evolution of the situation. I am from Salento, but I live in Northern Italy. So, I would be able to the GOOD INFORMED of the zone of the OLIVE TREES, who writes on this FORUM, if he would say something… thanks.

Hello. I have two olive trees that have been hit by strange green insects of about three cm that are literally devouring the leaves. There are so many and they fly. From an internet search, I may have identified them as cantharides. How can we eradicate them? I had confirmation that it is most likely that insect with the stench that hasn't even let us breathe for about three days. Help me!

I'M SORRY! I do not know this insect but based on your descriptions maybe they are bedbugs !! maybe if you tell me the symptoms that the olive tree is having, I could help you ... ..

Maple tree bark disease and damage

Canker fungus maple tree bark disease

Several types of fungi will cause cancer on a maple tree. These fungi are the most common maple bark diseases. They all have the same thing in common, which means they will create lesions (also called cancers) in the bark, but these lesions will look different depending on the carcinogenic fungus affecting the maple bark.

Nectria cinababine cancer - This maple tree disease can be identified by its pink and black shorts on the bark and typically affects parts of the trunk that were weak or dead. The latter can become slimy after rain or dew. Occasionally, this fungus also appears as red spheres on the bark of the maple tree.

Nectria galligena ulcer - This maple bark disease will attack the tree while it is dormant and kill the healthy bark. In spring, maple leaves a slightly thicker layer of bark over the fungus-infected area and then, the following dormant season, the fungus will kill the bark again. Over time, the maple will develop a cancer that looks like a pile of paper that has been split and removed.

Eutypella cancer - Cancers of this maple mushroom look similar to canker of Nectria galligena, but the layers on the canker are usually thicker and do not come off easily from the tree trunk. Also, if the bark is removed from the cancer, there will be a visible light brown layer of fungus tissue.

Valsa cancer - This maple trunk disease will normally only affect young trees or small branches. Cancers of this fungus will look like small depressions on the bark with warts in the center of each and will be white or gray.

Steganosporium cancer - This maple tree bark disease will create a black, brittle layer on the tree bark. It only affects bark that has been damaged by other maple problems or diseases.

Crypto Cancer - poriopsis - Cancers of this fungus affect young trees and start as a small, elongated ulcer as if someone has pushed some of the bark into the tree. As the tree grows, the cancer will continue to grow. Often, the cancer center can bleed during spring lymph onset.

Bloody cancer - This maple tree disease causes the bark to appear moist and is often accompanied by some bark moving away from the maple tree trunk, especially further down the tree trunk.

Basal cancer - This maple fungus attacks the base of the tree and causes the bark and wood underneath to rot. This fungus looks very similar to a maple tree root disease called collar rot, but with collar rot, the bark typically doesn't fall off the base of the tree.

Galls and Burls

It is not uncommon for maples to develop growths called galls or burl on their trunks. These growths often appear as large warts on the side of the maple tree and can grow to enormous size. While often alarming to see, galls and briars do not harm a tree. That said, these growths weaken the tree trunk and can make the tree more susceptible to falling off during windstorms.

Environmental damage to maple bark

While not technically a maple tree disease, there are several damages caused by the climatic and environmental bark that can happen and it can appear that the tree has a disease.

Sunscald - Sunscald occurs most frequently on young maple trees, but can happen on older maples that have thin skin. It will appear as a long, discolored or even bark-free stretch on the trunk of the maple tree and sometimes the bark will crack. The damage will be on the southwest side of the tree.

Frost cracks - Similar to sunscald, on the south side of the tree cracks, sometimes deep cracks appear in the stem. Queste crepe da gelo si verificano più comunemente nel tardo inverno o in primavera.

Over pacciamatura - Le cattive pratiche di pacciamatura possono far sì che la corteccia attorno alla base dell'albero si spezzi e cada.


Disinfezione delle ferite

Bisogna saper come disinfettare le ferite, con poltiglia bordolese concentrata al 3%, preferibilmente durante la stagione secca e quando l’albero non sia umido. Successivamente bisogna stuccarle, per evitare possibili infezioni da crittogame, così come l'invasione di uccelli o insetti o persino dell'acqua piovana. In caso contrario, l'infezione potrebbe estendersi attraverso la fessura e creare del marciume discendente, secco or umido.

Questo platano ha patito molte vicissitudini e gli rimane solo la corteccia. La stuccatura con un prodotto cicatrizzante è una misura estetica del tutto inutile (persino controproducente) per I'albero. Se I'albero non si trova in una zona pericolosa, I'unica cosa che è opportuno sperare è che il platanofinisca i suoi giorni degnamente. Sicuro che ha già svolto completamente il suo ruolo. In nessun caso si deve riempire la cavità con cemento come spesso si può vedere.
