Dendrocalamus giganteus is the largest bamboo ever. He reaches a height of 30 meters at his home location in Thailand. The stems of the giant bamboo become up to 25 cm thick. It is cultivable as a container plant because it is not hardy, and reaches a height of a few meters, depending on the size of the tub and the conditions.
 
Sprinkle bamboo seeds for 24h in lukewarm water (about 30 C).

For sowing,swell in water and place in a plastic pot.

Spread some seeds on the peat pot and cover thinly.

Then put the plastic pot in a zip-lock bag - with a pot size of 6 cm we recommend a zip-lock bag of size 120 x 170 mm. Put enough tap water in the zip-lock bag with a few drops of universal fertilizer so that a few millimeters of water remain after the substrate has been absorbed.

Location: on the windowsill or in a miniature greenhouse partially shaded, during the day the temperatures should be around 27 - 32 C, at night a bit lower at 25 - 28 C. 

The germination time for bamboo seeds is between 10 and 40 days, depending on the variety.
