Almost all communities will have local food bank that could use financial donations, which they use to cover operation expenses, and also to purchase better quality foods such as canned meat and fish, and dairy. These groups are also usually needing more volunteers.
I’m in the Master Gardener program, part of the Land Grant University Cooperative Extension Service in each county (type Master Gardener and your state’s name to find the local connection). Where I live in SE Washington we have a program called Plant-A-Row, where gardeners are encouraged to plant an extra row or two of food crops and donate the produce to a local food bank. We have a Master Gardener booth at Home & Garden Shows, Farmer’s Markets, the county fair and give away free seed packets for this.
Many communities may have clothing banks. In addition to donations of clothing (work cloths will be especially in demand in the spring when agricultural work starts) these REALLY need volunteers with sewing skills who can repair donated clothing. Monetary donations are used to buy socks and underwear.
There is a huge need for diapers for families who can’t afford the cost, we can hardly keep them on the shelf at the St. Vincent DePaul Conference I volunteer at. You might check with local hospitals to see if they can recommend groups that need baby things.
