Although I deadhead when flowers die, I seem to get lots of leaves and hardly any flowers. Why?
Please write back and let me know which plant it is you have. It would help me to better diagnose your problem. Some plant species are deadheaded different than others.
In the meantime, please review our article on deadheading flowers:

I have a plant from last year and want to know if I have to replace it.
If kept in the ground, will they spread so you will have more plants the following year? I love these flowers and and would like them to cover a 12 x 12 foot area.
It all depends what flower you are talking about - what kind of flower is it?
What do I do with the leftover flower stalks?
Flower stalks left over from spent flowers can simply be cut away from the plant (at the base) and disposed of or tossed into the compost pile.
I planted 2 large bags of wildflower seeds in an area that we completely removed the sod and dug down to rich soil. The flowers started coming up but now there is so much grass it looks like part of our lawn with edging. Should I dig the area up and replant or wait?
You may want to hand pull as much as you can while it is still relatively young. You can also spot treat the grassy areas with boiling water to kill it but be careful not to come into contact with your flowers as it will kill them too. Also, if there is enough room around your plants, lay some moist newspaper down and cover this with a layer of mulch. This will keep the grass and other weed plants from growing in that area.
What is the clump of little pumpkin looking things in the middle of the flower? Why did my pretty yellow flowers become just green?
What do you do after all the flowers fall off? Do I cut it back?
