I've enjoyed the challenges of gardening in zone 5 -6 and zone 10 - 11, and am wondering about others' experience.
Climate change, with migrating pests/diseases and more erratic weather, are definitely noticeable trends.
While it's interesting to grow ornamentals and food crops that wouldn't ordinarily be available, it's also disturbing to find falling yields and utter collapses of formerly successful "easy" plants like basil and temperate climate tomato varieties.
There are limits on how much can be accomplished with purely "organic" controls - I've had to experiment with soil ecology (MycoStop for fungal infections, etc.). Allergenic plants are an increasing problem. There are brand new animal pests where I live as well - iguanas, pythons, and other hot-climate reptiles.
I'm curious about others' gardening results, and suggestions for improving adaptability.
