I will begin planting an orchard using the HD concept in the area of Michoacan. México.
What will be the best density mangement?

We have been planting Hass with a density of 3X3 m. They are grown as single leaders with early fruiting. If in Mexico Hass don't fruit early you may consider girdling or this density may not work.

I dont understand why you mention that If in Mexico Hass don't fruit early you may consider girdling or this density may not work, and also I dont get precisely what do you mean by girdling.

Thanks a lot.

I don't know at what age after planting Hass starts flowering and setting in Mexico. There is a lot of information about girdling both in English and Spanish on avocadosource. Anillado is the term in Spanish.

Thanks Reuben,

Hass Avocado Trees in Mexico start flowering a bit normaly a the third year of planting, however it depends a lot in the quality of the starting plant and the management, principaly water and fertilizer, because many orchards in Mexico are managed rain fed(very hard to believe to the chilean right?).

Its good that you knew the term girdling in spanish, thanks. Actualy, your answer surpriced me a little, I would have never tought about girdling such an inmature tree; at what age after planting you start practicing girdling in order to incentivate flowering? Do you do that to the main branch(central leader)? when do you start with the GR?.

Muchas Gracias, Saludos.

Alejandro Sahagun

I would girdle a central leader if this is all you have. If any branching exiat I would consider girdling 1/3-2/3 of the main branches with a fine cut in the autumn. This hopefully will bring about some early flowering.
I think young trees have more flowers that most people think and early production is not usually noticed because of the large spacings and the low number of trees. When you plant in high density Hass with 1000 trees per hectare by the second year you will find what is considered at least average production for an adult grove in regular 6x6 m spacing. Again, my reasoning for high density planting is not altogether production driven rather a system that functions well on hillsides.

Amigos
hay que tener cuidado con el anillado de plantas en el área de Uruapan ya que al realizar esta práctica ponemos en peligro el troco a los atacques de cánceres de tallo. Reuben tiene razón al indicar que hay que forzar que el árbol ensaye su floración lo más pronto posible, no hay que eliminar las primeras flores y frutitos tal como lo hacen varios productores en Michoacán, ya que los frutos controlan algo el crecimiento del árbol y de esta forma se puedan manejar mejor.
Saludos
