How do I stake a Dahlia plant?
Otherwise, use a 4 ft stake, because most dahlia plants seem to have an average height of 4 feet. To keep the stake upright, tie the stake to the container using plant tie-wir e (or string, if preferred). Drill 4 holes in an “X” or “+” position (depending on the plant’s growth) in the sides of the pot near the rim. Cut a piece of plant tie-wire at least four inches longer than the diameter of the pot. Fold the wire in half and wrap the middle of the wire around the stake at the same level with the height of the pot’s rim and twist the tie wire to the stake. Remove the plant label which is near the eye end of the tuber and replace it with the stake. Next, thread one wire end through one of the pot’s holes and twist to secure it, then thread the other wire through the opposite hole and pull the wire taught until the stake stands upright next to the stalk of the plant. The base of the stake should touch the bottom of the container. Repeat with the other set of holes. Occasionally, two stakes may be needed if there are two main stalks growing from the tuber. Tie the stalk (s) to the stake (s). Return the plant label to its pot. (To keep the labels from becoming separated from their pots, mainly due to curious baby raccoons, I am going to experiment and use those aluminum name tags which have tie-wires thread through holes in them and attach them to the drilled holes in the pots.)

Why do dahlias die in the winter?
Some dahlias are affected by sudden drops in temperature (within 20 minutes) from the 80’s into the 50’s (F) due to a thunderstorm (with rain or hail) or by an electrical storm (lightning and thunder only). These situations seem to trigger a winter season shut-down even though it’s the middle of the summer. The leaves droop as if the plant doesn’t have enough water, even though a check of the soil proves that it is moist. Let the soil in the pot dry out before watering again. Many times this will get the plant to regenerate and start growing again and flower nicely. Sometimes only the buds will continue to develop and bloom. Sometimes the plant will die.
