^They don't look like Tassies. The pods are uniformly round. Hard to tell though as they are quite dry (or the picture colour is washed out). Look like giganthemum or maybe afghan......
when I mess around too much I've always had issues
Yeh pops don't like too much handling or interference , but successive crops will deplete the soil somewhat.
Some may find it gross but a liter of urine contains up to 0.9% nitrogen, 0.12% phosphorus and 0.26% potassium, of course you want to dilute it first at least 1/15 and avoid foliar feeding but it's relatively self buffering so it's hard to overdo it like with synthetic fertilizers.
A light feed of Mg in the form of epsom salts is helpful for boosting M content also.
Ahh.... the memories...
I wonder what they do in tassie to prevent this. I'm sure a lot of it comes down to sowing times.
