Pine Tree Farms Holiday Bird Seed Wreath

I love these wreaths

I love these wreaths. I have been buying them for years from another online retailer but they did not stock them this year. So happy to find them at the mill. They are the perfect gift for all the little old ladies in my life!

My horse likes it

Horse likes it, I don't like the molasses in it. It freezes and is hard to scoop out in the cold.

3-Way Tall Fescue

Heavily overseeded in September '25 with the 3-Way Tall Fescue. Applied The Mill's starter fertilizer a week after seeding. A month later and the results speak for themselves.

BEST lotion! I cant get this anywhere near me

BEST lotion! I cant get this anywhere near me. I looked online and found the Mill carries it so even though its expensive with shipping costs, its so worth it. It says hand lotion but I use this on my feet (I live in flip flops) and it is literally the BEST!

Great for Fancy Chickens and Bantams

I switched my Nankin bantams to this feed and they're doing great. They actually consume less of it so a bag lasts a long time. Less mess than crumble, too.
