BTW I am in zone 6b. Although, I not quite sure what that means.
Sure, here is a link to the seller that I bought mine from:
Sorry to say that they are all sold out right now but at least you know where to get them.
As soon as I felt uncomfortable for the weather, I moved them inside. Although, there are some trees that had to tough it out. I think that it dipped in the 50s a couple of times. But I moved them in before it got too significantly cold. As long as you see new growth, your pretty much good.
Now, as for germinating them, that was easy. The thing is is that you need to keep the seeds moist at all times.
First step is to peel the skin off of them. That is easy, let the seeds soak in water (I literally used tap water) for a little while, maybe a few hours. This will allow peeling the skin easier.
Second, now you need to somehow simulate the temperatures of the tropics for the seeds to germinate. Simple, buy a plastic container, a heat lamp, and paper towels and a washcloth and some fine mulch (that is optional but this will give some room for the roots grow. For me, the roots grew into the cloth, then I put some dirt down) Put the washcloth in the bottom, then the mulch, then the seeds and then 5 layers of paper towels. Soak em in water. Close the lid and put them neat a window and turn the heat lamp on. Check everyday, at least once a day to make sure that the paper towels are still moist. Keep them in there until the root starts growing down. At that point, you can take them and plant them in pots.
I used a method similiar to this one:

Now, I did a little experiment. In some trees, I planted them in fine mulch and others, some really good planting soil. Both work. Just make sure that the pot can drain water and make sure that the soil is moist. If the soil is moist when you check it, then you are good. If not, water them.
Now, when I say fine mulch, you do not have to go to a specialty online store. No. I went to Home Depot and was able to find fine mulch there. I will let you judge what is fine and what is not. Also, I remember reading that miracle grow killed someone's cocoa tree. So do not get that. But that is about it. Fine mulch and you are good. I haven't really tested anything else but hopefully this bone meal, potting soil, and worm castings mix will be better then the mulch. For now, stick to the mulch for some of them. I know it works. And for others, experiment. I tried using the soil that I found in my backyard, that did not work.
Also, since there is a possibility that yours will grow slowly then everyone else, that has been my experience also. Could be because of the climate.
I hope that this helps you. That is practically what I did. Oh and for fertilizer, farmers in the torpics use the cacao husk and coffee grinds. So, I would say, use that. I am actually allowing my husk to decompose along with some grinded up coffee beans. But that will take awhile. I know that someone is using coffee grinds for fertilizer and that tree is doing fine. I want to recommend chemical stuff but since my trees are turning out like this, I am going to pull them off of it. Actually, that is the main reason I repotted these. I wanted to get them out of the chemical stuff I put them in. Instead, I added bone meal and worm castings. Nutrient rich. Maybe one day I will add fertilizer. Hope this helps
