Text Box: Substrate
The potting media should be of a well aerated and coarse structure. We recommend a coarse peat, well decomposed leaf mold and perlite. On capillary matting we recommend about 10% perlite and for ebb-and-flow irrigation 15% perlite should be added to the mix. The optimum pH is 5.8—6.0

Disinfecting of Benches
Benches need to be cleaned and disinfected every time a new crop is placed on the table. We recommend Greenshield or Zerotol for fungus control. Drench tables before plants are placed on the table with 1 ppm.

Temperature
After potting 72F should be maintained (night and day). As soon as the plants are well rooted, 68F is sufficient (night and day). During the last stage of the crop 65F (day) can be maintained in order to get a more intensive flower color (night temperature 68F). Growth regulation by negative DIF is possible.

Shading
The shading screen should be adjusted to allow for 1600 to 1800 foot candle.

Artificial Light
For lighting Begonias there are several possibilities. It is however not necessary to light the plants to make them bloom.

1. Assimilation lights during the entire crop period. The light intensity which should be used, is 250 to 300 foot candle. Total day length should be 14 to 16 hours. The lamps should be programmed to come on once the natural radiation intensity is lower then 400 foot candle.
Text Box: Growing Elatior Begonias
 
Today’s assortment offers the possibilities to grow a good quality Elatior Begonia all year round. A good planning of the varieties scheduling of the growing periods and the correct application of the cultural measures are very important. We hope the following outline will be of assistance in your Elatior Begonia crop
Text Box: 2. Another method when growing under assimilation lights is to use lights only during the first 4-5 weeks. After this period plants are spaced and can be placed at about 8W per square yard. 

When using assimilation lights dosing of CO2 can be continued during the period of lighting. A dose of 650 ppm is most economical, never exceed more then 800 ppm.

After Potting
Use Fungicide drench after potting to control Rizoctonia and Pythium.

Pest and Disease control
Common Pest problems are with Aphids, Mites, White Fly, Thrips, and Fungus gnats.

Common Disease problems are with Powdery Mildew, Botrytis, Phytium, Foliar nematodes and Xanthomonas Begoniae (bacterial blight)
