Corymbia citriodora is a tall tree, growing to 35 metres in height, from temperate and tropical north eastern Australia. It is also known as lemon-scented gum, blue spotted gum, lemon eucalyptus and eucalyptus citriodora.
?Use Jiffy peat swell pots for sowing, let them swell in water and put them in a plastic pot. Alternatively, a commercially available sowing substrate can also be used.

Spread a few seeds on the peat well and cover thinly with the sowing substrate (about 2 mm).

Then place the plastic pot in a zip-lock bag - for a 6 cm pot size, a 120 x 170 mm zip-lock bag is recommended. Pour enough tap water with a few drops of universal fertilizer into the zip-lock bag so that a few mm of water remain after the substrate has been vacuumed up. 

Location: on the window sill or in a mini greenhouse in partial shade, during the day the temperatures should be around 24 - 28 C, at night a little lower at 20 - 24 C. 
price is for 20 seeds
