Oh I'm not a commercial grower at all. But I do read on their blogs to get ideas, helps or even if a type of plant is worth trying.
Sand I'm inundated in and have been adding a lot of me made compost to the soil to help it out. We just finished filling the heap with chopped up leaves from what came from our trees. I do have to be mindful w watering due to my city water costs as it's not super economical and though we've had good rainfall it's been in the crazy world of deluges the last few summers a whole lot in a very short time. I've been thinking of adding a rain barrel but haven't quite gotten on that train yet and need to save money for.
Yes we have extension agents but due to the covid the last I knew they weren't doing a lot with the regular outside people and their test samples when I last looked they stopped taking samples in for testing at the university. Heck even 4H is out of commission much to the chagrin of my kids. I have an agronomist in the family so I should hit them up for ideas as well.
Your breeding is producing some interesting looking flowers and colors. How did you start if you don't mind me asking? I save seeds all the time from other plants both annuals and perennials, and in fact just ordered myself a large box of coin envelopes thank you amazon. In the next few weeks I'll be getting them cleaned up and away.
Do you have a thread on your breeding creations? I always like looking at new forms or colors people have helped create.
