Starting a plant nursery can turn out to be lucrative business, provided it is suitably located. The location should ideally be close to residential localities, where locals can drop in, without inconveniencing themselves and shop for what they want. I am using my experience from visits to nurseries to best answer your query.
The investment you make will depend on the expanse of the property. You will need to build a greenhouse for the plants and a concrete shelter for your customers and for business transaction. Apart from that you will need basic furniture for office use and for customers to sit. Fans, drinking water, a toilet are a few things that you will need to provide, for your customers benefit. You will also need to get the plumbing work done, and install pumps and motors and lay pipes to water the plants. You will need a storage area that can be kept locked, where fertilizers and pesticides and other potentially hazardous items can be stored, safely. You will also need display cabinets for seed packets and root hormones etc. You will also need gardening tools, brooms, water hoses and sprinklers, etc. for use in the nursery.
You will also need to hire a couple of knowledgeable gardeners cum caretakers.
As for plants, invest in a variety of plants. You may use the following tips as a guide
1. A variety of flowering plants
2. Local plants
3. Ornamental plants
4. Exotic ornamental plants
5. Indoor plants
6. Potted plants
8. Miniature or dwarf varieties of fruit/flower bearing trees
9. Palms and ferns that can be used indoors as well as outdoors
11. Medicinal plants
15. Hardy plants that do not require much care
16. Hybrid plant varieties
You can also sell manure, different types of soil, gravel, compost, fertilizers, pesticides, hormones, seeds, grass etc. You will need old sacks, to transfer these into when you sell.
You will also be able to sell the following:
1. Hanging pots
2. Ornamental pots
3. Pot stands
4. Pots of various sizes and material
5. Gardening tools
6. Spray guns and other apparatus for fertilizers and pesticides
7. Gardening gloves
