Bob, Most nursery's will not purchase the plants unless you have enough to make it worth their expense of them coming out with their equipment and people to get the plants. If you do have a plant that is in high demand you may luck up because they will come out to get the plant and pay you for it. However the economy has hit nurserys pretty bad. You can always call around to local nurserys - the one's that plant their own plants, usually they are wholesale nursery's. You can also mention to the nursery's that they could come to cut off parts of the plants so they can make cuttings, maybe you can make a deal with them to remove some plants while they are there. Many wholesale nursery's do not advertise in the telephone book so you might have to get some names of places from a place that sells supplies for landscapers, we have Southern States here. You may be about to get a list from your state. There maybe some listed on the internet. You can always post the types of plants you have on Freecylce. Just tell the people to bring a shovel. My local Freecycle has posted plants that someone whated to get rid of and had a huge response. I don't know where you live but around here people love plants in their yard so be sure that you just thin out what needs to be but leave some plants. They say that landscaping is one of the best investments when selling your home. If you plan to hire someone to come in and landscape it would be cheaper on you if you had some of the plants already removed so the landscaper will not charge you for that. One important thing about getting a landscaper, ask them about places that they have landscaped. Then go look at their work. There are many landscapers that cut corners & plant things too close to the house (like my house) One advantage is since the economy has hurt nursery's and landscapers is a very competive market right now. In hard times people only spend money on things that they have to have. I wish you luck with your project. If I lived near you I'd love to come over to help you, I enjoy working in the yard although digging up a plant or shrub takes me a long time, not strong enough. Good luck, I hope I've helped you. Please feel free to email me if you have any questions. My father owns a nursery so I can ask him. Plus there are many other people in this group that know a lot about plants. Lisa
