Seed and plant catalogs help make the winter days go by. These are available online but sometimes it's nice to be able to leaf through the pages. This is just a sampling of sources for seeds, bulbs, potted plants and garden supplies. I thought it might be helpful to list these with a link to the online sites:
Breck's Burgess Seed and Plant Co. Burpee Dutch Gardens Exciting Gardens Farmers Seed and Nursery Gurney's Seed and Nursery Co. John Scheepers Johnny's Selected Seeds Kelly Nurseries Michigan Bulb C. Park Seed Seeds n Such,
One of my favorites is Outside Pride
An excellent place to go for ideas as you make plans is Happy DIY Home https://happydiyhome.
Happy gardening starts with a plan.
