I live in zone 7b. I have enough acreage that I can hopefully make a difference in the amount of pollen and nectar that my bees have available by providing different plantings. We have a long summer dearth and a marginal fall flow. I need something to fill in the long gap during the dearth and help prop up my hives if/when the fall flow is non existent. Long term I'm looking at planting some Bee Bee Trees to help give a boost during the summer.
When privet is over, our flow is over until Goldenrod. What can I plant to help fill in that long gap? I have 3 acres that I planted in Crimson Clover last fall. That won't help much because it will be blooming during our normal strong spring flow. I have that 3 acre area to plant, along with 5 more acres that I could plant in something. We have 120 acres and while I can't plant the whole place in bee food, I can plant areas around the whole farm and probably be allowed to plant on my neighbors farms also.
What are some plants that can be planted from seed that you guys would recommend planting? I've thought about trying Borage. I don't know how much area 1lb would plant but a quick Google searched shows that I can buy 1 lb for about $55. That's sort of pricey but if it keeps coming back it would be a worthwhile investment.
Please offer up any plants that would provide mid summer pollen and nectar.
