Hole in the fruit-bearing trees. What may end up as a cure
If formed hollow, it should cover up in the tree. Otherwise, this place will be stagnant water, the tree will begin to rot inside. Subsequently, it can be completely hollow inside and a strong wind still ever fall.
You need to determine to start, whether it is worth to do with putty hollow. It also happens that a tree has no help when the cavity inside the practically rotted. Should stay inside the still thicker wall, some support (at least half of the diameter). If there is one, the tree can still be saved.
Next, you need to try to pull out all the dust out of it. Then you need to treat this place Vitriol (three-percent) with the sprayer. To 1 liter of water required 30 grams of material. Iron sulfate can be replaced by copper.
Then it is necessary to dry the wood in a hollow (that was without puddles). If handled in the morning, in the evening you can make a "seal". This is assuming that there is no rain, and the wind blows.
How to make a solution for the "seal"
This will require the sand (3 liters), lime (100 g), cement (1 liter). The solution is very similar to the plaster and make it better with the stock (because you can not guess, may not be enough). Typically, you will need to 1-1.5 liters of water to prepare a mixture.
It is necessary to mix all of the dry, then add a little water. The solution should be a thick, no draining from the spatula. With the latter lay neatly weight in the hollow, and to cover up all the cracks, so that water does not leak into the hollow.
About a month after the procedure is necessary to paint over plaster "seal" garden pitch.
