Good Product

I ordered about 30 combined pounds of PV Premium Soil Builder Mix (Raw Seed) over the last two months. I am currently getting fairly good germination (about 75%) and the plants seem strong and vigorous. However, I would say that the description should be a bit more clear to customers in presenting that an inoculant should be purchased to accompany these seeds. I attribute my lack of product here, to my less than 100% germination.

Excellent product

I bought this mix last year and sowed it in the early spring. I soon had a luxurious carpet of vetches and field peas, and better still, the bees came back to savor the blossoms, and it was wonderful to be working the garden and listening to the hum of contented bees. Then I let my chickens have at it. The plants worked wonders for the garden, plus I used some of the dried/spent grasses as mulch for my tomatoes. I bough another bag of Premium Soil Builder this year, and am sowing it in an area I missed last time. I highly recommend this blend.

Great Growth -- Doesn't Over-Winter

This mix took off in my Montana garden. I planted in mid-August, and it was waist-high by the first killer frost in mid-October. The first winter I mulched half of it (before the frost), and everything that was covered didn't make it until spring. But some of the uncovered mix , the grasses primarily, did. That was some nice early green-up. The second year the completely opposite happened. The uncovered mix didn't make it, but the legumes under the mulch did. Weird weather, eh? In any event, I've planted tomatoes where the mix was both years and, like its name says, this cover mix built my gravelly, old-river-bed soil so the tomatoes love it. The only down-side to the mix is it's heavy and costs a lot to ship.

Great to prep Garden Soil

I planted this to renew my soil in the off season in the garden. The following year's crop turned out amazing.
