In Appreciation Of Coconut Fronds

Coconut fronds are easily available in our area. They have many traditional uses -- broomsticks, roof-base for thatch, fuel in wood-burning stoves. We chanced upon this indigenous material while looking for options for unconventional uses at the farm. This post this about those applications.

To keep the house cool, we wanted to block the heat coming in though the windows that were facing east and west. We thought that the window blinds used on the insides won't be as effective as attempting to block the heat on the outside. Commercial outdoor window shades were expensive and were likely to get worn off after a few rains. We finally decided to use coconut fronds for this purpose. We had a pile of woven coconut fronds (keethu) from a previous project. We just tied a few of them in the following fashion and hung this panel off the roof. This thin layer surprisingly blocked off radiation and kept the rooms cool. Yes, it is a chore to hang up the panels in the mornings and take them off in the evenings. But the gains are quite satisfactory.

We have a circular chicken-mesh enclosure that contains the composting material. Our summer heat was drying up the compost pile and preventing it from decomposing well. We tried wrapping an old cotton fabric; it was working only till we had a gust of heavy wind during which this acted as a sail blowing the entire enclosure away. We had to come up with something else. We then planted coconut fronds all around the pile and tied them to the mesh structure. This is working just fine keeping the moisture content inside the pile intact.

In a span of just a few weeks we get a lot of brown leaves in the village. Many trees shed their leaves around the same time. We wanted to harvest this brown matter that could be used later as mulch or composting material. We wanted an inexpensive place to stock up all this bio-mass. Our farm worker Dhanraj built one for us using coconut fronds. He first made panels with the fronds, then tied the panels to the four posts of the enclosure below. One of four sides of this enclosure is operable.

I noticed that little tree saplings were struggling to survive in the summer heat (42 deg C). The heat here peaks between 2 and 3 p.m. Blocking the afternoon heat became crucial. I planted coconut fronds in a line to do just the job. Three months into this, I know that these little plants have got over the hump. This flimsy, protective heat barrier is giving way, but it has done its job and at no cost! The mulch in the picture below is coconut frond leaflets discarded after broomsticks are made.

I plan to use light-weight frond tips on trellises to create partial-shade condition below for shade loving plants. The beauty of these fronds is that they are entirely local, mostly discarded and zero-cost. If they cease to offer the protection that we are looking for, they simply become part of the soil; there is no waste.
