Experiments with Seeds

Each year's seed-sowing: Seeds 2021  Seeds 2020  Seeds 2019  Seeds 2018 Seeds 2017 Seeds 2016

I've always wanted to plant seeds and in recent years wanted to figure out how to do it more successfully. Results have been so hit and miss. I need to document and collect data: test

1. How long from sowing seeds until flowers are produced?
