We have one hectare of lanzones and normally buy the rights to another 10 to 20 hectares every year. The fruits in our area are normally ready from the end of August until October. When the flowers first appear in April/May we estimate how many fruits each tree might produce at harvest time and put in our bid accordingly. It is always a bit of a gamble as sometimes nature plays tricks and the yield is not as much as you had estimated. Price can also be a major factor as it starts of high then goes down as more fruits are harvested during the season. Have had a couple of very good years when we have doubled our money. Will post some pictures of our trees tomorrow.
