Deflasking

After finding our compost we deflasked some of our seedlings.  We took out 2 jars of plants that were 2 years old and ready to be potted up, and a few smaller ones which unfortunately had contaminated.  The big ones are now at home in the shade house above the library, and the smaller ones we are keeping an eye on in the lab.  They are all doing well and should be moved to the shade house soon.

Replate Media

Having used up all the replate media replating, so we had to teach them how to make replate media. The students were all hands on, and are understanding the concepts of sterile and, how to create those conditions. Hopefully the next replate session we will have power all the way through, so we will get less contamination. Replate media

Replating

We had our first go at replating with lots of people having a go. People learnt quickly and it was lovely to see the students explaining it to fellow students if they didn’t understand our English. We had a bit of trouble as the power cut out half way through which meant we had a bit of contamination but will have another go this week.  Replate

Hunt for Compost

We started by finding small chips of charcoal from the kitchens, and then we put the smallest wood chips which we found near the KCCEM road where the saw milling activity has taken place.  And then we made a mixture of those chips of wood and charcoal, ready for the orchids to be potted into.

The importances of each components that are used to make compost

  • wood chips: it play good role in holding water near the roots of orchid,
    facilitate aeration into the pot because the orchid does not like the compacted root zone
  • charcoals: it play  role of providing the carbon content to the orchid,
    charcoals also have the capacity to absorb water and be kept at long time to be used by orchid, charcoals also play the role of controlling the pests including the mites ,termites, and aphids

Not only those components are used for planting the orchids but also there others like chips of erthrina abyssinica is its common  name (red bean trees) its kinyarwanda name is UMUKO belonging in fabaceae family which is an indigenous species in Rwanda.
