KOHLERIAS & How to Grow Them

Starting Your New Plant
Using your regular potting mix, fill a 2.5 inch pot about 2/3 to ĺ full of mix.
Lay  your  rhizome  on  the  mix and fill the rest of the pot with soil.  Water
and  set  aside  until  you  see  the  green sprout come up.  Keep it moist not
wet.  If  your rhizome is quite large, you can break into two or more pieces.
I  generally  use  a  piece  one  inch  long  or  the  entire  rhizome if smaller.
Some rhizomes can be quite small, others as long as 7 to 8 inches.  You may prefer to keep the rhizome in a ziplock bag until you see signs of sprouting so you can centre the growing point in the pot.

Growing On
Your kohlerias will be happiest in a  bright sunny window, under 4 fluorescent tubes or if your climate is suitable, outdoors in a patio pot.  Part day or dappled sun would be preferred to direct full day sunshine which could cause the leaves to burn.  Kohlerias benefit from frequent pinching to keep them compact and sturdy and to make a bushy plant.  If you are planting them outdoors, do remember that these plants are not perennial in North America and must be protected from our cold temperatures.  Grown indoors they are happy in the same type of conditions as your African Violets, except that they appreciate a little more light or some morning sun.

Maintenance
Well, when you werenít looking, all of a sudden your young plant got long and leggy. In fact it wonít stand up any more, but wants to sprawl along the shelf basking in the light, and crawling over the neighbours. 













On a day when the plant is fairly dry and in need of watering, remove the plant from its pot and take off all those lower spaced out leaves until you have a nice compact fresh looking crown.   Prepare a larger pot with your usual mix at the ready.  Holding your plant in your hands, gently bend the stalk over sideways. Usually there is one direction the plant is more willing to go in. 












Slowly push on the stem gently easing it over. Now slowly turn the root ball in your hand continuing to apply steady but gentle pressure, while winding the stem around the root ball.  When you reach the point where your new crown is you can go ahead and pop it into the new pot. If it doesnít want to hold together, a small  elastic band works well.   Place it in the new pot so the leaves will be just above soil level, fill the pot with soil mix and water well.  Voila - a brand new plant looking great. Donít be upset if you hear the stem crack during this operation or even if you know it has a break in it. The plant will simply make more roots at that spot.

Another solution for an older plant that has grown too tall for the light stand or is no longer attractive due to a long bare lower stem, is a sharp knife. Cut the top of the plant off cleanly, at a point where you have nice new healthy growth.  Remove the lowest one or two sets of leaves, and set in a pot of soil less mix appropriate to the size of the cutting. Water in. Kohlerias are extremely strong and resilient plants. They will usually continue blooming even through this operation, while making a whole new root system.  If you are at all nervous, you can simply lay a piece of plastic wrap gently over the plant to help hold in humidity while it roots, or place the cutting in a propagator.  Do check the pot for rhizomes before you throw out the tired bottom half of the plant.

Dormancy
Some kohlerias, particularly the species, have a tendency to go dormant.  If your plant has started to die back after a long period of blooming, donít despair.  Cut back on the watering a little bit and wait until the plant has lost most of its leaves.  Remove the old growth to soil level.  Now you have two choices.  You can set the pot aside, watering occasionally to keep it barely moist and wait until the plant sends up new growth, or you can remove it from its pot and mine for gold. You are looking of course for the rhizomes the kohleria makes before going dormant.  Collect your rhizome or rhizomes in a ziplock bag with a little damp vermiculite, and set aside in a dark cool place,  until you are ready to plant them,  or if you prefer you can go ahead and set them in fresh soil without waiting.
