Description Like other cycads, the queen sago resembles a palm tree with its featherlike leaves arranged in a rosette that crowns a single trunk. It is a larger and more graceful version of its more commonly encountered cousin, the Japanese or king sago ( Cycas revoluta ). The queen sago's solitary trunk can grow to 20 ft (6.1 m) in height, more than twice that of the Japanese sago. In older specimens some branching may occur, producing very handsome plants with multiple crowns. The dark green pinnate leaves grow to 8 ft (2.4 m) in length with narrow 12 in (30.5 cm) leaflets that curve gracefully downward. New leaves are light green and contrast dramatically with the older foliage. This species is dieocious, with male and female reproductive parts on separate plants. In late winter the male and female "cones" emerge from the centers of the plants. Pollen from the male cones fertilizes the female cones. A colorful show results later in the season when female plants produc...

Coco peat  ( cocopeat ), also known as  coir pith ,  coir fibre pith ,  coir dust , or simply  coir , is made from coconut husks, which are byproducts of other industries that use coconuts. Coir waste from coir fiber industries is washed, heat-treated, screened and graded before being processed into coco peat products of various granularity and denseness, which are then used for horticultural and agricultural applications and as industrial absorbent. Usually shipped in the form of compressed bales, briquettes, slabs or discs, the end user usually expands and aerates the compressed coco peat by the addition of water. A single kilogram of coco peat will expand to 15 litres of moist coco peat. Trichoderma  is a naturally occurring fungus in coco peat; it works in symbiosis with plant roots to protect them from pathogenic fungi such as  pythium . It is not present in sterilized coco peat.  Trichoderma  is also destroyed by...
