The Q&A Archives: hedychium gardnerium

Question: I am getting ready to divide the rhizomes, my soil is clay, the established plants do ok. What type of soil should they be planted and when. Do you recomend any other variety?



Answer: Zingiberaceae Hedychium gardnerianum, or kahili ginger, blooms in summer and fall, but rests during the winter months and that's when they should be dug and divided (anytime between December and February. These plants are quite adaptable to most soil types, but since you're digging and dividing, take the opportunity to amend your planting beds with some organic material (compost, aged manure, shredded leaves, etc.). Simply spread a 3-4 inch layer over the top of the bed and work it in to a depth of about 8". This will make the roots of your ginger happy by loosening the soil and helping the soil hold just the right amount of moisture. As the amendment continues to decompose, it will release nutrients.

For additional interest to your ginger bed, you might try growing Hedychium angustifolium 'Peach' or Hedychium coronarium, a white flowering ginger. For even more interest in the garden, Hedychium sp. 'Dr. Moy' is a variegated hedychium, and Hedychium greenei is a red leaf ginger.

Best wishes with your garden!
