Germination Time: 7-10 Days For Germination Temperature: 20-25 Celsius Lighting - A North Window Is A Good Location. Although The Plants Do Not Require Direct Light, They Would Not Do Well Away From A Window, Unless You Prefer To Grow Them Under Fluorescent Grow Lights. Supply All But The Hottest Sun. Soil - A Moist, Well-drained, Light Soil - African Violet Soil With Some Added Perlite - Is A Good Growing Medium. Watering - Keep The Soil Moist In Spring And Summer, Dry But Not To The Point Of Shriveled Foliage In Winter. In Dry Climates More Frequent Watering May Be Necessary. Temperature - Give Them Medium (50 Degrees) To Warm Temperatures During The Growing Season-spring And Summer. The Plants Go Semi-dormant In Winter. Fertilizer - In Spring Hoyas React Favorably To Feeding. A Liquid Food, About Every Four Weeks, Three Or Four Times During The Growing Season Will Produce A Vigorous Growth. Withhold Food During The Winter
