Are my plants dead after a frost?

I live in Tennessee and we had nice warm weather so I planted some shrubs and flowers. We then had a big freeze and I woke up to my leaves wilted on my plants and my flowers dead. I have had other shubs out there for over a year. My question is even though the leaves wilted off of my shrubs, are the plants dead, or will they sprout new leaves. It's been about a month since the freeze and my plants look the same. Do I just need to pull them up and plant new shrubs or will they come back?

Are my plants dead after a frost?
If you brake a piece of twig off and it cracks then it is gone, if it is though to break and still green in side the it is still good. As far as flowers yes replace them.
Reply:living in the north east we get this problem alot





just let them rest for about a week


see if they spring back


take the dead leaves and buds off and let them thrive


you can give them a little plant food if you want they will need all the help they can get
Reply:It really depends on the plant and its responses to the environment. Some will die, some will grow again, some will grow, but not till next spring. You can find out by checking your plants "hardiness" or "cold tolerance" you should find these specs on the containers you bought the plants with or freely on the net.


What plants grow good this time of year in zone 9? Starting from a seed?

I was wondering what plants grow good this time of year in zone 9? I want to grow them from seeds, but what type of plants are easy, cheap, and good to grow in zone 9? i know that spring is comeing up, and this is one of the good times of the year when plants begin to grow and bloom, but what type of plants are good? i like vines herbs and cented plants best, but i want to grow what ever i can from seeds, or buying them from the store. I thank you if you can answer this question a lot!

Moss rose
Reply:there are too many to list but rosemary, lavender, jasmine are some of the plants that do well in region 9 but be careful about vines they can grow really fast and you might have a hard time controlling the growth. I strongly advise you to visit a local nursery and get as much information about which one will do best depending of the size and area of planting.
Reply:crocus, they even bloom through the snow!! also check out: http://www.brecks.com/Default.asp?bhcd2=...





then click on spring blooming on the top left side.
Reply:Zone 9? Anything except the cool weather annuals. Just throw the seeds in the ground and jump back.


What plant or plants use the most CO2 and produce the most Oxygen?

Are there any good websites or books that discuss plants that use the most CO2? And is there a significant difference from plant to plant? I'm looking for planting options for my property.

What plant or plants use the most CO2 and produce the most Oxygen?
Trees would produce the most I would assume. Try posting your question in science or botanty.


Why do all plants contain at least some green on them? How do plants DEEP in the ocean get energy to grow?

Obviously....there are probably some plants that I don't know of that don't have any green, but what causes most plants to have the color green on it, and what causes plants not to be green at all?





Also, how do plants WAY deep on ocean floors get energy to create food for themselves and such? Also, why don't those underwater plants drown, like regular land plants?

Why do all plants contain at least some green on them? How do plants DEEP in the ocean get energy to grow?
Most plants are green because most plants use chlorophyll and that itself is green. If a plant doesn't have chlorophyll then it won't be green.





Many plants at the bottom of the ocean are not green and don’t use chlorophyll. Some plants in shallow water do, but if they live more than 25 meters below the surface then the amount of sunlight that reaches them is so minor that they can’t rely on chlorophyll. They need some other energy source.





Hot Smokers are volcanic vents at the bottom of the ocean and a lot of plants and animal life develops around them using that energy to live. Otherwise the bottom of the ocean is almost a desert, in fact it has less life than many deserts because the only source of food is the dead and decaying bodies that parts that have fallen from the surface.





Corals are small animals that act like plants. Coral reefs are built (literally) on the bones of the coral. They are the home for a lot of plants and animals. Most of them are filter feeders; they pull the water in and filter out plankton and other nutrients. A few plants are able to survive this way.





Plants don’t drown for the same reason fish don’t drown, they pull the water in extract what they need and expel it.





According to Wikipedia:


"Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from Greek: chloros = green and phyllon = leaf. Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green color of chlorophyll-containing tissues like plant leaves."





According to Wikipedia:


"Plant life is relatively rare undersea. Most of the niche occupied by sub plants on land is actually occupied by macroscopic algae in the ocean, such as Sargassum and kelp which are commonly known as seaweeds. The non algae plants that do survive in the sea are often found in shallow waters, such as the seagrasses (examples of which are eelgrass, Zostera, and turtle grass, Thalassia). These plants have adapted to the high salinity of the ocean environment. The intertidal zone is also a good place to find plant life in the sea, where mangroves or cordgrass or beach grass might grow. Sea kelp is very important to small sea creatures because the creatures can hide from predators."





According to Wikipedia:


"A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots...





Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, and shrimp...





Life, as most people understand it, is driven by the sun, but deep sea organisms have no access to sunlight, so they must depend on nutrients found in the dusty chemical deposits and hydrothermal fluids they live in. Previously, marine biologists assumed that vent organisms were dependent on a "rain" of detritus from the upper levels of the ocean, like deep sea organisms are. This would leave them dependent on plant life and thus the sun. Some hydrothermal vent organisms do consume this "rain," but with only such a system, life forms would be very sparse. Compared to the surrounding sea floor, however, hydrothermal vent zones have a density of organisms 10,000 to 100,000 times greater.





Hydrothermal vent communities are able to sustain such vast amounts of life because vent organisms depend on chemosynthetic bacteria for food. The water that comes out of the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria. These bacteria use sulfur compounds, particularly hydrogen sulfide, a chemical highly toxic to most known organisms, to produce organic material through the process of chemosynthesis.





The ecosystem so formed is reliant upon the continued existence of the hydrothermal vent field as the primary source of energy, which differs from most surface life on Earth which is based on solar energy. However, although it is often said that these communities exist independently of the sun, some of the organisms are actually dependent upon oxygen produced by photosynthetic organisms. Others are anaerobic as was the earliest life."
Reply:Wow, someone asking a question that does not sound like a homework problem!





There are some plants that are not green, but they are rare. The green is a chemical called chlorophyll. This chemical helps plants capture the energy of the sun and use it to make food. Plants take energy from the sun + water + carbon dioxide and turn it into sugar and oxygen. This process is called photosynthesis. Chlorophyll is the most efficient chemical plants have discovered to capture sunlight so almost all plants use it. There are some other chemicals, called accessory pigments, that can also capture sunlight but not as well;they are generally red.





There are no plants deep in the ocean. There has to at least be some sunlight to have plants.





Land plants drown when their roots are unable to get enough oxygen at night because the air has been pushed out of the soil. Seaweeds do have roots that go deep into the soil. They just have anchors that stick to rocks. They get bother thier nutrients and oxygen through their leaves.

How do I transplant small plants like little citrus plants safely without killing them?

I have several citrus plants that are sharing pots with main plants. I don't know how to go about taking them out without killing the plants. I also have a two logan plants as well and they seemed to be entwined by the root to a massangeana cane.


What species of plants have life cycles that include more than one type of plant growth in the same species?

I remember reading years ago about some plants where the plant grows and makes seeds, then the seeds grow and a plant that looks unrelated grows from the seeds. Then the new plant will grow and make seeds which grow into the plant that you started with. Can anyone please tell me what these plants are called, and where could I find information about them?

What species of plants have life cycles that include more than one type of plant growth in the same species?
Ferns have this life cycle a protothallus a sexual phase of reproduction that looks nothing like the adult fern. Think the term applied is alteration of generations


Plants.....?

I have had a problem I am growing some tomato plants and they have started to die on me. I think this was deliberate can anyone tell me what would kill a plant that's in a liquid form and is also odourless

Plants.....?
There are a bunch of chemicals that can kill plants. I would assume a lot of different cleaning chemicals and even household salt could kill a plant.





But why do you think someone killed it deliberately? Bugs and animals are also known to kill plants (climate as well). There are a lot of factors to consider, but I highly doubt you will ever find out what chemical it was or who did it without the help of a specialist.
Reply:Too much water? Lots of random chemicals.
Reply:over watering can kill a plant.
Reply:Probably any number of things. Salt water around the roots is one thing. If it got sprayed with roundup or the like you'd probably not know it until it died. Interesting you think it was deliberate. Did you do something to someone that may be trying to get back at you?
