Croton megalocarpus trees develop a deep taproot. This makes them quite drought tolerant and allows food crops to be grown underneath[ ]. The foliage provides good mulch[ ]. The croton husks are milled for fertilizer. Croton nuts have relatively high nitrogen content comparatively to typical composts and manures. The fruit shells are used as mulch in vegetable gardens and as a component of potting mixtures[ ]. Animal feeds: Croton seed cake is used in animal feeds.
The flowers provide nectar for honey bees; the honey produced is dark and has a strong flavour[ ]. Other Uses: Seed oil is tested as bio-fuel[ ]. Oil extraction from the seed is done by hand-operated or mechanized screw presses. The oil may be refined in a continuous transesterification reactor to produce bio-fuel of diesel oil quality, with glycerol as a valuable by-product[ ]. The press-cake remaining after oil extraction can be utilized as bio-fuel and as an organic fertilizer[ ].
The seeds can be used to dye wool yellowish[ ]. The heartwood is yellowish white to brownish grey, often with irregular dark brown streaks; it is not distinctly demarcated from the 25 - 50mm wide band of sapwood.

It is easy to saw and work with hand tools, but moderately difficult to machine; it usually planes to a smooth and lustrous surface; is resistant to abrasion; nailing, screwing, gluing, varnishing, painting and jointing properties are all satisfactory. The wood is only suitable for sliced veneer. The wood, most commonly known as?

It prefers light, deep and well-drained soils[ , ]. Established plants are drought tolerant[ ]. Being a natural pioneer of large forest gaps and forest margins, regeneration of this species is often prolific in the wild. It has been reported to become invasive under favourable climatic conditions[ ]. A fast-growing tree in favourable conditions[ , ]. In Kenya seedlings reached a height of 1. Trees may already start flowering when they are 4 years old. The flowers are short-lived and pollinated by insects such as bees.
Fruits take about 5 months to ripen after flowering[ ]. The tree can be managed by lopping, pollarding and coppicing[ , ]. When planted in hedges, plants should be pruned for the first time after 2 years[ ]. Preliminary observations indicate that a yield of 25 - 30 kilos of seed per tree per year is realistic[ ].
At the end of their productive life in bio-fuel plantations, approximately 50 years after planting, trees can be felled for their timber[ ]. Our new book to be released soon is Edible Shrubs. Shop Now Propagation Seed - does not require pre-treatment, but is best sown as soon as it is ripe. The seed is generally sown directly where the tree is to grow, though it is also sometimes sown in a shaded position into individual pots and then planted out later.
Because of its high oil content, the seed has a relatively short viability of around 9 months[ ]. Weed Potential Right plant wrong place.
