Growing Coffee from Seed

As I mentioned in a previous post, we wound up starting about 100,000 plants from seeds last year. I get pretty excited when I see the "viveros" (nurseries).  It is better to wait until the rainy season to start seeds, so you don't have to do a lot of manual watering.

What we found out is that it really is best if you can start seeds in your own soil. The plants do better if you start them in the same type of soil as they are going to live in later.

You have to start the seeds in the local soil, after the rainy season begins, which in our region (Matagalpa state) starts in April.

Starting plants from seeds.

In the photo above, you can see the seeds sitting on top of the tiny green stem of the plant. In some cases, you can see the seed shell coming off the first set of leaves. When the seedling gets to be about 4" tall above the level of the soil, with two leaves, it is transplanted.   It is important to make sure you only keep the plants which have ONE root (a "bifurcated", or double root, is not a plant that will grow well).  You can see the date in that photo above is 7/30/2010. We should have started these sooner, but last year is the year that we bought 100,000 plants and lost 60,000 to fungus. It takes about 4-5 weeks for the plants to be ready for transplantation.

The seedlings are out of the common bed of soil, ready to go into their own individual bags of soil.

The seedlings after they have been transplanted into their own bags. You can see the row of bags in the back of the photos has the most immature plants.

This is a vivero of very young plants. They thrive in filtered sunlight with daily waterings from Mother Nature, and from us, if it doesn't rain on time.

These plants are bigger. They have four leaves on them.

If you are patient, and lucky, and the weather is good, and about a billion other things go right, your plants eventually look like this:

Can you see why I get excited?  Below you can see how the plants look once they have been transferred to the soil of the farm. 
You can see one of our young coffee plants next to the scarecrow that one of our workers has carved with a machete into this tree stump. The scarecrows are carved to scare away the devil. The wood is infiltrated with a particular type of fungus that makes it soft that makes it look black and furry. You can also see some young coffee plants behind the scarecrow, under the older trees.

Q Grading Coffee

You know how last week, I told you we would have between 4000-5000lbs. of cafe oro (a.k.a. green beans)? Turns out we are going to have between 5,000 and 10,000lbs. this year.

One of the three contiguous parcels we purchased that comprise Finca La Cumbre today already had mature coffee on it when we purchased it. We have yet to identify what the variety of that bean is. Here are some photos for you, in case you have some idea:
The field of mature coffee plants on our farm. Can you tell us what the variety is?

Ripe coffee beans from the mature plants on the farm.

Last year, in April we purchased 100,000 plants of Caturra Estrella. Sixty thousand of those plants died from fungus. We replaced those by starting our own from the same type of seeds. We also discovered that copper sulfate is an organic-approved fungicide.

We will be starting 100,000 coffee plants from seeds in April, when the rainy season begins. We are trying to figure out whether we should save the beans from the mature plants on the farm. We obviously have more than enough beans. We just don't know how good, objectively, the coffee our mature plants are producing IS.


After quite a bit of research, we came across the logically named Coffee Quality Institute (CQI), which has created a coffee grading system that is globally used. They also provide the training that official coffee graders attend. Turns out that we can have our coffee graded using their system by their local ICP (in-country partner), the AsociaciĆ³n de cafes especiales de Nicaragua (ACEN). Lots of acronyms, but eventually we sorted it all out. So our coffee sample will soon be on its way to the ACEN official graders. They will have three certified graders each score our coffee independently. 


I will, of course, let you know how it goes.
