There is a site called tropicalpermaculture.com which has some useful information on growing tropical fruits.
For those of you interested in Jackfruit, the fresh seeds from a ripe jackfruit I bought in Ensenada are sprouting wildly. One seedling succumbed to damping off but at least a dozen others are looking good.
As the dragonfruit which were planted about ten years ago are beginning to give us a significant crop it is encouraging to have another food plant coming along.
