I am a beginner in the gardening world. I'm curious as to how to remove spent blooms on Dahlia plants? Is it at the bulb, or base? Thanks for any advice you can give! -Rob

Dahlias will produce more flowers if you deadhead or remove the old faded flowers. Find the leaf node immediately below the bloom on the stalk; cut off the spent blossom at this point with your pruning shears. Dahlias often develop clusters of flowers. You can either allow each flower to open and then deadhead it as above or you can thin out the unopened flower buds just as they are forming, leaving the center bud alone. You'll have fewer flowers on your plant but those that open will be much larger. Hope this clarifies things for you!
