Feed the plant regularly with liquid fertiliser and water it in dry periods. In early autumn, stop watering, dig up the pot and lie it on its side to dry off. The leaves will die off and the nutrients will pass back into the leaf bases to make a plump new bulb. It is now ready for repotting and watering to wake it again. No 14 gave a list of ideas for investigations with mosses.
Many gardeners find it hard to kill moss in their lawns.
Perhaps mosses are not as sensitive to some weedkillers as are other 'weeds'. They can be put down the sink, but with plenty of water. The capsules of mosses make beautiful objects to study. Put some plasticine onto a microscope slide and poke the base of a capsule into the plasticine. Put the specimen under the microscope and observe it under low power with a reading lamp shining onto the specimen.
