I won't remember!
I now record everything- however I choose to- sometimes I email myself, or
I record things by phone camera pictures, knowing the picture records both the date and the subject, or I make an online calendar event standing in the garden- like when I plant seeds and another event when I see them sprout, or when I start harvesting an item-
So I can scroll back next year to see those events as a record of my timing archived as it was this year.
Screenshot or printout the seed orders- double-seed-buys are a thing!
I won't remember!
I now tag everything. Plant a row of peas? Tag it.
Divide a perennial? Tag it.
Up-pot those tomato seedlings?
Try two varieties of beans on the same row?
Fertilize some pots this week, but waiting till next for other?
Tag-Tag-Tag.
Did I ever remember all these details anyway?
