After hyacinth flowers fade, what do you do?
You can cut the stems off once the flowers have faded, unless you would like the plants to naturalize. If you would like them to naturalize, simply leave the seed pods on. Do not cut the leaves until after they have turned yellow and died down.
I bought a potted hyacinth from the grocery store last spring. I followed the instructions on how to keep it for this year. Once it started showing green through the soil, I brought in from the patio (I am in Melbourne, FL. ) and set it on a windowsill to get plenty of sun. I also began watering it. The plant was doing great for a while, and then I noticed new green sprouting in the soil. In about a week, the new blossoms started to die off and the new sprouts were getting bigger. I know now is not the time for transplanting or separating bulbs. They are currently in a six inch pot. What can I do to get blooms this spring?

Will hyacinth plants thrive in Zone 7?
Yes, you can grow these plants in Zone 7 and they should be fine. However, you should keep in mind that in Zone 7, you may have trouble getting them to chill over the winter. They need at least 7-8 weeks of temps below 45 to bloom the following year. These articles will help:

I received a beautiful pink Hyacinth plant for Easter. It has four bulbs in the pot. I would like to eventually plant them in my garden. When can I plant the bulbs, and do I have to wait until there are no more flowers on them? I know to plant 8 inches deep and 2 to 3 inches apart.

Are hyacinths an annual plant or a perennial?
They are technically perennials but some varieties have a hard time surviving for more than a few years.
I got a plant at a baby shower, which is beautiful and already flowering. I live in Minnesota. Is it possible to put the plant in the outside in the ground? Or can I wait till the flowers die off and then plant it in the ground for next season?

What can I do with the pods left on my hyacinth plants? Can I plant them for new bulbs or just cut down the whole plant after it has flowered?
You can grow new hyacinth from the seed pods, but they will take many years before they are mature enough to flower. Most people simply cut them off and allow the plant to focus on storing energy for next year's blossom.
You can cut the seed pod off, but do not cut the leaves off until they turn yellow. The leaves are how the plant builds energy for next year's bloom.
