In Reply to: How to get faster growth from your slow growing Tokudama type hostas? posted by Dave on May 31, 2001 at 03:19:45:
: I know good soil, water, fertilizer, and proper levels of sun vs shade will help hostas to grow best. Does anyone have any tips for getting faster growth- bigger leaves more rapid development of multiple divisions, on Tokudama types and other slow growers such as special fertilizer, mulch, soil amendments, garden locations, etc?
I think I can answer my own question based on my own experience this year and articles in The Hosta Journal Volume 32 Number 1 (Spring 2001). Read Hostas Sun or Shade? by Kevin P. Walek or Sun or Shade: Too Much of a Good Thing? by Bob Solberg for some great info on hosta sun tolerance.
By planting tokudama types in areas with more than 3 hours of sun but not more than 5 or 6 hours, they will grow much faster than normal shaded ones. Keep them watered evenly (but don't wet leaves during daylight hours) so that they receive moisture every 3 to 4 days or when soil is dry. I have found that most hostas will grow rapidly if given large doses of sunshine but not quite full sun (unless they are the few that can take full sun- Fortunei Aureomarginata, Sun Power, Green Piecrust, Christmas Tree, Honeybells, Sum and Substance, Royal Standard, Guacamole, August Moon, Francee, August Lily, Fragrant Bouquet, there are several others).
I placed tokudama "Blue Shadows", tokudama "Golden Bullion/Medallion", Tokudama, and Aspen Gold in bright sun this year and had fantastic growth. I planted Tokudama Aureonebulosa and Tokudama Flavocircinalis 3 years ago in a shady location and they are now all roughly the same size. Aspen Gold and Golden Bullion are bright gold plants able to handle a lot of sun but the other two have been pleasant surprises for their sun tolerance. The only drawback is that Tokudama is no longer blue but dark green due to the exposure.
If you try this with your slow growers be sure to water often and thoroughly!
