I have a couple of Google sheets. I tend to be a little obsessive and detail focussed, so I record a lot of things.
The first sheet is a list that I use to supplement my plant list here on garden.org. I record fields like:
- do I have it, want it, or have decided against it (very useful so that if I see it in a thread and go "ooh, maybe I should get that one" I can check to see if I've already decided against it and why)
- the size group (SDB, TB, etc.)
- cultivar
- colour group (yellows, reds, blues, purples, whites, pastels, etc.)
- colour description
- reblooming/non-reblooming
- PBF
- fragrance
- bloom life
- where I got it from
- who else I know likes it (so that I know who to offer it to when I have too many)
- what other plants in my collection or wish list it might be similar to (helps me avoid too many similar-looking irises, or if I was unimpressed with a particular cultivar but want something similar, I know what to try next)
- any other comments I might have
The second workbook/document is for my hybridising (I do this for my Orchids and Liliums as well). One sheet is simply for ideas, where I note down which two plants I might want to cross, what I want to achieve with the cross and what "priority" I put on it. The other contains a record of crosses I've tried with information like:
- Pod Parent
- Pollen Parent
- When I attempted it
- How many pods I set
- How many pods took
- When I harvested it
- How many seeds I harvested
This helps me to know (1) if I've already thought of an idea and why I wanted to try it and (2) which crosses (and which direction) worked or failed.
