Plant Material and Nurseries


We assume that the new plantation will develop its own plants from seeds. Seeds cost at the moment 25 guilder per gram. A gram has about 2500 seeds. The seed comes from the seed capsules of the Rubiaceau, which are collected in bunches, dried in mesh cages, then carefully sorted. The actual seed has a hard core in a wing shaped membrane. The sorting of the seeds takes places by putting a small quantity on a glass plate. With a chicken feather the seeds are separated from the cores. The seed cannot contain loose membranes.

The seeds are then sown carefully onto square seedbeds. No more than 4 grams should be sown on each square meter. The sewer takes some seed on his hands and carefully blows it on to the bed, trying to distribute the seed evenly. The seedbeds are protected by a grass roof from the sun. It also allows rain to trickle carefully on to the seeds. The watering of these beds requires great care. Too much water in one flow will destroy the little plants. After three weeks the seed have become little plants. After two months they can be planted in bigger beds. After 9 months they are moved outside.

For the Cinchona Ledgerina Moens seeds are taken to planting areas, until the moment the gardens are ready to take them. For the Cinchona Succirubra another process is used. Another plant is attached to it and grown into it, so that a tree with a richer quinine content can grow.
As you see, all these processes take about two year before the development of the plantation. When one has started on time you don’t have to buy plants. You can grow the ones you have cultivated yourself.
