>> it's double or more here
Yuck. I hope some of that is shipping cost! I know that NY/NJ is horribly over-priced, BUT!
(Do you know what prices are like down around Princeton farm country?)
>> I need to organize the seed packs by # week before average last frost and get my greenhouse ready
I made a table in Word, for 11x17" paper, listing things according to seed pkt and online sowing guides. The "avg last frost date" is just a row across the top, so it could be modified quickly for other regions (if "last frost date" were the only variable that mattered).
Following the usual seed pkt convention, I made boxes for
2-4 weeks before,
6-8 weeks before and
10-12 weeks before,
and also
4-6 weeks before and
8-10 weeks before
I assume those figures are to be taken "inclusively", so each box overlaps by one week before and after.
I currently have two major rows: Inside and outside. I should probably split "outside" into "direct sow outside" and "set out transplants".
But all of this is based on what I read, not experience. For example, where I live, snow peas should have two different boxes: one for "direct ROT peas outside 0-4 weeks before last frost", and "direct SOW peas 1-6 weeks after last frost".
