Drosera will doing better if we protected them from rain. But, it is costly, and troublesome to build a wood or metal cover for them. It will be “NO” for stingy person, especially me (always calculate here and there).
With suitable size of square container (im using transparent disposable plastic food containers) and transparent A4 paper, we can build 1 easily. Make a hole at side of container for water overflow purpose. Distance of the overflow hole from bottom of container is 2cm. Fill in the container with wet spagnum moss. Then, plant yours CP in the spagnum moss.
Cut the tranparent A4 paper to shape as shown
Slip the two shorter sides of the cut tranparent A4 paper into the planted container.
Final product.
