The African violet – a gift for the holidays


African violets were the first houseplants I remember growing as a child.  Walk into any garden center or supermarket floral section these days and you are liable to see a nice display of African violets.  These traditional flowering houseplants not only make a great Holiday gift idea for the gardener, but also have a place in every home.  These plants do well in low light, (even artificial light), and come in a wide variety of flower colors and leaf style and texture.

So, you bring your African violet home and wonder where to place it so that it gets the correct amount of light.  These plants will do best with indirect light.  African violets will tell you if they are getting enough light.  Too low of a light intensity, and the African violet will not flower well.  Too much light will result in leaves that are pale or yellowish-green.  The literature indicates that an African violet needs about one thousand foot-candles of light for eight to twelve hours per day – in other words, bright, indirect light. 

Hand-in-hand with light requirements is making sure your plants receive the proper temperature.  Try to keep your night to day temperatures between seventy to eighty degrees F.  Temperatures over eighty degrees F can affect growth and flowering.  Air conditioning can help provide an even temperature.  In association with temperature of course is humidity.  Humidity can be maintained by placing pots on pebble-filled trays of water.  Make sure that the pots do not touch the water directly.

Ready-to-use African violet potting soils are usually available at any retail garden center.  The soil medium is generally made up of peat and perlite (volcanic material) which provides water retention and good drainage.  Water African violets from the top or the bottom with room temperature or warm water.  Using a good liquid fertilizer at intervals recommended on the package label will ensure good growth and frequent flowering.  Good leaf color and normal flowering are signs that your feeding program is working. 

Even novice gardeners will find that African violets are very easy to propagate.  In as little as six months you can grow a new plant ready to flower!  Leaf cuttings (with the petiole - leaf stem-attached) are made by snapping or cutting a leave from the original plant.  Make sure that the stem is about one and one half inches long.  Insert the leaf stem into a sterile potting medium.  Insert this leaf into a pre-dug hole made with a pencil and firm the medium gently around the cutting.  Expect roots in three to four weeks and leaves in about another month.

Pest control will include monitoring your plants for pests and always quarantining new plants to prevent introducing infestations.  Cold water can cause spotting on leaves - use warm water as mentioned earlier.  Soluble salts that accumulate on pot rims can cause problems to leaf petioles from chemical burns.  The cure for this can include watering from the surface to flush excess fertilizer salts away or by using fertilizer less frequently.

African violets are real gems of the houseplant world – give one as  a gift this season!  For more information on all types of houseplants, please call our Master Gardener volunteers on the Plant Lifeline on Mondays, Wednesdays and Fridays from 1 to 4 pm at 764-4340 for gardening help and insight into their role as an Extension volunteer.  Don't forget to visit our other County Plant Clinics in the area.  Please check this link for a complete list of site locations, dates and times - http://charlotte.ifas.ufl.edu/horticulture/Plant%20Clinics%20Schedule.pdf.
