This granular formula, utilizing 'binary’ technology has been in use for over twenty-five years. Developed by world renown hybridizer, Kenneth Landon, this product has produced some of the most beautiful plants ever grown. After some 20 years, Ken agreed to release this formula for general use and we were asked to make it market ready and to introduce it to the trade. 

LANDON 7803 is a combination of both organic and inorganic ingredients that work in conjunction with one another to create spectacular results. It is a very ‘hot’ formula that requires very strict adherence to the directions for use. These instructions can be seen on this site. In using this formula we suggest that you combine the appropriate amount of fertilizer with soil and fill your container three quarters full. Add the tuber and cover with(unfertilized) soil. Cover with gravel and place in your pond. Take this products for plant growth.

Typically, this fertilization method should be sufficient for 60 to 90 days. If late season fertilization is needed, use tablets per manufacturers instructions. This is the only fertilizer used in the International Waterlily Certified Collection and Repository located in San Angelo, Texas, where Ken is the Horticulturist.

After trials at Longwood Botanical Gardens in Pennsylvania it is now the fertilizer of choice for growing show stopping specimens.
