WATERING
Over-watering is the most
common reason for failure with violets. They die within a short time with the
leaves turning jellylike and drooping over the pot rim row by row until even the
central core of the plant rots away. If violets just die on you the problem is
probably over-watering. If they live, but just won’t bloom the light is probably
too dim for too much of the day. Not watering enough or on an erratic schedule
rather than when the plants need it will cause violets to grow slowly and
irregularly, but it usually won’t kill them.
Wick watering is a growing
method which provides plants with proper water, fertilizer, and humidity. It is
by no means fool proof, but is a great improvement over traditional top or
bottom watering. Start slowly and be sure that you are doing it properly. The
wrong soil, too large a pot, or too much wick cord can kill a violet.
A very simple way to try out
wick watering is to cut a hole the size of a dime in the lid of an empty, clean
margarine container. Fill the margarine tub with water, snap the lid on and set
the violet on the lid with the wick extending down into the water. If you
dissolve some plant food in the water the plant can water and feed itself at the
same time. When the plant has used up all of the water in the wicking container
do not refill it right away. Let the violet sit on the empty container for 3 or
4 days so that the soil can dry out a bit, then refill the container. Never let
the bottom of the pot sit in the water as this will over-water the plant and may
cause the roots to begin to rot. Every 6 to 8 weeks when the soil happens to be
nearing dryness (and the reservoir is dry) top water the violet with warm water
until it drains out of the holes in the bottom of the pot. Leave the violet sit
over the empty reservoir until the soil begins to dry out again. Then resume
wick watering. This top watering with plain water is called flushing. It rids
the root system of the gradual build up of fertilizer salts which can be
harmful. For wick watering to be successful it is best to use a soilless potting
mix such as Violet Showcase Potting Medium which is a mixture of peat moss,
perlite, vermiculite, and charcoal. Ordinary violet soil, no matter how well it
may work for you by traditional watering methods, is usually too heavy for wick
watering. Also, you must not grow your wick watered plants in too large a pot
due to the risk of over-watering.
Wicking cord comes in two
sizes: thin and heavy. The thin wick is suitable for any size pot simply by
increasing the number of pieces used according to the size of the pot. To
determine how many pieces of the thin wick to use with a pot measure the mouth
of the pot (round down fractions). Subtract 1 from that number. That is how many
pieces of the thin wick to use. For example, for a 3" pot use 2 pieces of wick.
For a 31/2" pot, also use 2 pieces. For a 4" pot use 3 pieces. The heavy wick is
the equivalent of three pieces of the thin wick and is therefore good for 4" or
4 1/2" pots. But not for pots smaller than that. Don’t expect a wick to work
forever. After 6 - 8 months wicks can get clogged with minerals in the water,
fertilizer residue, and soil particles and may need replacing. It is also wise
to replace the soil at that time. You may get a wick to last for a year, but
rarely longer. It is best to put a wick in a pot at the same time that the
violet is repotted rather than trying to put one in after the plant is already
potted. Make each length of (thin) wick 6 or 8" long. Cut as many lengths as the
pot size requires. Remember, pot diameter minus one equals number of lengths of
wick. Insert the wick(s) up through one of the drainage holes in the empt pot
and hold it up at the top rim of the pot. Put 1/2" of moist Potting Medium in
the bottom of the pot and lay the wick(s) down on the soil. Next, pot the plant
on top of the wick. Unraveling or fancy placement of the wick(s) on the bottom
1/2" of soil is unnecessary. The wick will bring the water up to thoroughly wet
the bottom 1/2" of soil. The soil is so sponge-like that it will distribute the
water throughout itself. If you find that the wick just won’t pull water (for
example, the wick is in water, but the soil remains dry) check out the
following: How old is the wick? They are useful for 6 - 12 months only. Is the
soil lightly compacted so as to be in good contact with the wick? Is algae
present in the water clogging up the wick? Physan 20 is an algicide that will
prevent algae from forming. It can be safely used at each watering. Is the pot
sitting on the wick pinching it and restricting the flow of water up into the
soil? The wick must pass freely into the water reservoir below. Is the wick
crusted with fertilizer salts? After months of constant fertilization the wick
can become clogged with fertilizer residue. It is time for fresh soil in a clean
pot and for new wick cord.
