General Information

Macrozamia communis is a slow-growing, evergreen, palm-like plant with a usually subterranean main stem that in shallow soils can form an erect aerial stem 1 - 2 metres tall and 30 - 60cm in diameter. The stem is topped by a crown of 50 - 100, erect to spreading large leaves each around 70 - 200cm long[

An almost universal requirement for cycads is a well-drained but moisture-retentive soil, and by far the best soils are sandy gravels and light loams which provide the required drainage and aeration necessary for good growth. Cycads will generally not grow well in clay soils unless those soils are heavily amended with sand and organic matter[

Cycad species can usually be transplanted easily even when quite large. The best time for moving them is just before the beginning of a new growing season, the roots being trimmed if they are damaged and perhaps some leaves being removed. New roots should develop quickly as the season progresses[

Species in this genus form structures known as coralloid roots. These roots branch off from the taproot or secondary roots and are distinctive in that they grow laterally or upward, forming a nodular mass at the apex. These coralloid roots occur slightly below or slightly above the soil surface and generally contain cyanobacteria, also known as blue-green algae. These are able to fix atmospheric nitrogen and make it available as a nutrient to the plant. The ability to extract this important nutrient from the air explains how many cycad species are able to survive on almost sterile soils[

]. The pith is ground in water and the resultant mixture strained through a silk sieve to catch the fibrous material, allowing the starch to pass through. Finally, the starch is purified by leaching in water for a period of time, rinsing, then drying into a fine white powder. The resultant starch is of high quality and is said to perform better than starch produced from rice or corn[

Propagation

Seeds - best sown as soon as they are ripe, though the seeds of many species will take a few months to finish maturing the embryo before they are ready to germinate. Sow the seeds in a tray in a freely-draining medium and place in moderate shade. Bottom heat at about 27°c will hasten seed germination dramatically. Young roots are quite brittle and once germination takes place, the root grows rapidly. It is important to pot up the seedlings at this time in order to give them enough root-space. Grow on the plants in pots until large enough to plant out[
