Climate change is here now and it is hot, thirsty, windy and dangerous. And how it affects growing food is significant. Over the years, I've seen a lot of comments like “I know HOW to grow food, I just don't need to right now” or “yeah, when SHTF I'll be out there putting in a garden and hunting”.
Listen. If you aren't gardening right now, you don't know how to garden. I've been gardening my whole life and every year it changes, the climate changes, the zones change, the air moisture, humidity, wind, plants and soil water needs, changes in what varieties will do well in more heat, less water and humidity, length of growing season, - every aspect of growing food is rapidly changing and you need to adapt.
You will be lost in the weeds – no pun intended – if you don't start right now (better yet years ago unfortunately) to learn the basics and understand how climate change as well as other factors such as animal movement and migration, insects and pollinators, birds, rodents, and troublesome bugs affect your ability to make the most of your available growing space. Plant diseases are more troublesome as the planet warms up and the zones move north, along with fungal diseases, harmful insect migration, invasives, predators and prey.
Seed germination and viability seems to be becoming an issue the last few years. I'm not sure if it's supply chain, dishonest corporation practices, lack of expertise or what, but it is getting weirder. A couple of years ago we had pepper-gate (massive numbers of mis-labeled seed packages mainly with pepper varieties but also squash and other vegetables). This year has been a challenge to get kale and some lettuces to germinate for no apparent reason.
Last year we had a very late spring deep freeze which took out many kinds of fruit trees in BC. There were few locally grown soft fruits such as peaches to be had. So far this year, the blossoms are showing promise, so here's hoping.
The point is, grow food RIGHT now while you can learn and also have a monetary buffer while learning, during failures and while grocery stores have fully stocked shelves. During a societal collapse is not the time to find out that your soil is severely lacking in a necessary nutrient or that your growing zone won't support your stable foods or that the rats will eat you out of house and home. Learning how to deal with all of these issues now and sourcing out possible solutions in your local area while becoming familiar with typical ups and downs builds resiliency in your future security.
Especially the sour cherry is happy this spring. Fingers crossed that it will translate into some actual harvest
