Steps to Prepare Seeds from Coffee Cherries

  • Gently squeeze out the skin and pulp of the berry, and wash them with clean water.
  • Let them ferment in a container for almost 18 hours, so the pulp falls off, leaving behind seeds only.
  • Wash them again with clean water and discard those seeds that float as they are not viable for germination.
  • Lay out the seeds on the mesh screen and let them dry till 20% moisture remains, but do not use direct sunlight.
  • You can use their weight to estimate the moisture content of the Coffee seeds and stop the drying process as per the need.

Pro Tip: You can directly sow the freshly picked Coffee cherries without removing the pulp and skin.

The freshly harvested seeds can stay viable under optimal for almost six months without dropping the germination rate.

However, after four months, the germination rate can start to go downhill over time.

If you are not planning to sow Coffee seeds right away, store the seeds in a dry, dark, and cool place.

After soaking the seeds, you shall sow them directly on sandy, loamy or wet vermiculite.

  • Make a 1 cm deep hole in the light, airy, well-draining seed starter soil.
  • Ensure to place the seeds flat-side down.
  • Subtly sprinkle the soil over the seed but do not cover it completely, as light helps to germinate seeds faster.
  • Avoid pressing the soil on top of the seeds.
  • Add half inches of mulched grass over the soil to preserve the moisture, but remove once the seed germinates.

Step 3: Taking Care of Coffee Seeds During Germination

After sowing the Coffee seeds in nutrient-rich, well-draining soil, the real deal of germination begins.

You will need to give them ideal care to preserve seeds from rotting and encourage faster germination.

Therefore, to ensure you succeed in germinating Coffee seeds, follow these care routines.

  • Water the seeds daily to keep them moist, but not too much or too little.
  • Ensure proper drainage at all times, as improper drainage can lead to rotting.
  • Cover the germination tray with a plastic bag to preserve humidity.

Fresh seeds take two and a half months to germinate, while old seeds can consume 6 months.
  • Sparingly apply orchid fertilizer to maintain the soil pH at levels 6.1 to 6.5.
  • Maintain the temperature at around 65°F to 85°F for conducive germination.
  • Place the germination tray a few feet under the artificial grow lights.

If your Coffee seeds are more than four months older, they might take more than 4-6 months to germinate.

However, fresh Coffee seeds can germinate much faster within two months. So, try to find fresh Coffee seeds for better results.
