How to deadhead DIANTHUS?
Can someone please explain to me how to properly deadhead Dianthus? Do you simply cut off the flower head or should I cut someplance along the stem. If so, where on the stem would I cut. My Dianthus is starting to look sparse so I'm thinking I'm deadheading it wrong. I have 3 plants. One of my plants only has one flower on it? Help please? Oh yeah, do they like the soil moist or on the dry side? Thank so much for helping me with this.
