Water lily rhizomes come in a multitude of sizes and forms (those of a finger, a pineapple, a tuber, etc.). Usually, divisions of water lilies are sold when they are 10-15 cms long, while their diameter varies by the cultivar (from that of a finger to that of a small ‘pineapple’). Rhizomes of miniature water lilies are tiny, only 4-6 cm long. Depending on a variety, a division can weigh from several grams to a few hundred grams.
May is brimming with warm weather, sun and the promise of summer. It is also the time when nasty blankets of green filamentous algae appear on ponds. The mere sight of these algae drives into desperation owners of water features, and especially of the smaller kind. The green algae are not all bad - they absorb quantities of water-soluble nitrates and phosphates before other aquatic plants spring into action.
