The Question Corner

By Cheryl Salatino

 Question: When I had only a few African violets my plants seemed to be healthy and bloomed on a regular basis. Now that I have increased my collection, I seem to have lost the green thumb. What advice can you give to a grower who has learned all the basics, but can’t get the plants to perform?

Answer: Growing African Violets in New England can pose quite a challenge for even the most experienced grower. Our four seasons alone guarantee we’re in for constant change – and some ‘un-seasonal’ weather fluctuations. As a new grower, we quickly learn that a little tender loving care of our African Violets can yield great reward. The trouble usually comes when the collection increases and conditions change.

Consistency is the hidden secret – the missing ingredient – the fundamental must-have. Our New England environment works against consistency unless you work hard to maintain it. Take a thorough look at your growing conditions and determine the time and routine care you are able to provide. You found the ideal growing area for your first few African violets. Now that the collection has grown, your growing area has probably expanded or moved. You must carefully examine the existing conditions to determine if and when you achieve ideal conditions.

As you know, there are many factors that contribute to healthy plants. Start with these key elements to determine if consistency is contributing to your plant concerns.

Light. The optimal amount of light needed to grow healthy, blooming plants is typically 12 to 14 hours a day under florescent tubes. That requirement may be slightly reduced if using wide spectrum or special grow lights. Depending upon where your plant stands are located, natural daylight can be an added factor. As the angle of the sun changes during each season, the amount of natural light will vary. You may need to make modifications in the artificial light to accommodate for any light fluctuation. Of course, each plant also has unique light requirements, so watch its growth patterns to see if the placement on the shelf is ideal. Stronger light intensity occurs at the center of a florescent tube and the light weakens towards the ends.

Temperature. African violets like similar living conditions as most people – temperatures around 70 degrees. Our New England winters and summers really pose a problem with maintaining comfortable temps (at an affordable price). Consider alternatives in the growing area to minimize dramatic seasonal changes. Fans, cloth or plastic shelf covers, and heaters are just some of the options available to alter conditions. Be creative. And, don’t forget to assess the amount of humidity available during our four seasons. African violets thrive in a wide range from 40% to 70%. If you’re comfortable, it’s likely the plants will be too. If it’s too dry – try capillary mats, a humidifier, or add pebbles and water to the bottom of the trays. Remember extremes in either of these areas can have a negative effect on growth and blooming.

Water. Constant moisture is recommended for African Violets – not too dry and not too wet. Drown and drought conditions are a quick way to introduce problems and demonstrate a break in the culture of a plant. Remember, the temperature of the water also plays a role here. Tepid water is preferred. Often we leave water containers out overnight to allow chlorine to dissipate. During the cooler months, check to see if water in those containers has become too cold for the plants. Cold water can produce leaf spotting, curling of foliage, and slow down root and plant growth.

Once you’ve mastered the fundamental growing consistencies, take a look at the routine care you are able to give to your collection. Consistency in all areas of plant care really makes a difference.
