My plant math usually happens with volunteers.
I keep my seeds in a giant 5" three ring binder. I fold the packets in half and put them in trading card binder sheets. I do however have more seeds coming in the mail ...... Flower seeds. Last year was my first year growing flowers from seeds. It turned into a bigger operation this year since my favorite local nursery closed down. They had fair prices. I decided my money was better spent learning to grow my own from seed than feeding more money to Home Desperate. Especially for annuals.
The blackberries I ordered are thornless primocane. Prime ark freedom. These set fruit two times a year. I have two chester blackberries and will probably switch them out for these if they do well. Most of my berry bramble is Olallieberry. I started with one 13 years ago. Now from that plant I made 5 more; not including ones I've given away. Olallieberries sell for $20 per half pound, frozen here. $10 per basket fresh. It's crazy. I don't sell mine but I use mine every year. I got 12# last year. Made jam, syrup, and froze for pies. All gone except the jam.
Anyway, I digress.
That up there is all evidence that I probably don't need any more plants or seeds.
It brings me joy though! Both chicken math and plant math.

If I had a basement I'd be in trouble. More room to store jars... Mason jar math!
