Thanks for the kind words about "repeat offers" and OK germination!
I don't know how others feel, but if someone asks me for the same seed two years in a row, I take that to be a compliment to the seeds! (Or, as in your case, yet another instance of "I grew the plants, but the plants died" (to the tune of "I fought The Law, but The Law won".)
>> by the time I realized that extra land wasn't going to happen ...
That IS a problem with starting seeds indoors: "Now, where will I PUT them all??" (Starting enough to give some away is one way of concealing the fact that, really, we are just totally over-optimistic and want to cover EVERYONE'S yard with plants!)
Good luck with your HOA! My "park management" just brought in someone to "trim" my profusely-flowering Knockout Rose, AND my F. rufa bamboo like ##@#$%^## hedge, trample one nice hosta flat under work boots, and they MOWED DOWN a big patch of lovely ferns that sprang up when the same ##@$%## bums cut down two healthy trees!
Now that part of the yard is ugly bare rocks, clay, and low-lying weeds. But my looney neighbor who triggers all such complaints seems to hate all living things and treated her own yard that way.
I'd suggest being very forward about sharing garden produce and flowers-in-pots, or even cut flowers, with as many neighbors as you can. Give away seedlings in the spring. Cherry tomatoes in soda bottles. If your garden is super-popular with everyone who pays them rent, maybe they won't be AS annoying to you as they would be otherwise.
