Q.geraniums
When a geranium flower dies, how do you remove it? At the base of the stem near the soil or just the bud at the top?
Deadhead or remove the spent flowers down to the base of the plant. Most times you can pinch and snap it off with your fingers, but a small garden snip can also be used.
Keeping the plant deadheaded will help your plant produce more flowers for the growing season.
