I have herd that manzanos can be difficult to germinate. I am finding this statement to be true. I have planted roughly 10 so far with no success. I have tried planting them as one would any other seed and I have even soaked them overnight with no better results. The seed should be viable as I removed them from the fruit myself. My rocotos are another story, they have done fine so far. Is there anything else I can or should be doing to get these puppies to pop?Â
