walnut is overhyped juglone can prevent seed germination but it has little effect on plants over seedling stage. I have a massive shade garden under my Juglans Californica, and there’s plenty of mustard and grass growing under wild ones, so even the seed germination thing isn’t 100%.

I planted spicezee nectaplum- it’s a beautiful tree- dark purple leaves, self pollinating and has made it to fruit production faster than plums I planted a year earlier. Excited to taste the fruit this year.

Any everbearing citrus. It’s amazing that they fruit year round. The convenience of always having a lemon, can’t be beat.

Loquat. It just grows so well where I live, even if you don’t water it. Basically you can ignore it, and it fruits in a season when there’s nothing else. I just made a batch of loquat butter in my slow cooker.

My advice is if you need something electronic or mechanical and it’s expensive buy it now. I just replaced my hvac last month because I know this summer will be a mess. Most air conditioners are made in Asia. You want an e-bike, buy it now.

The more parts something has the more likely it’s going to be affected by tariffs.

Start growing some food if you can it’s a great way to be more resilient. I’d recommend buying things like coffee and tea and chocolate that are not easily grown in the US. There’s actually a pretty bad chocolate shortage right now I believe.

Also for other stuff, buy used, in thrifts or on eBay. Not only are you recycling, most sellers are individuals rather than big corps. Also, if you have old stuff you are not using, it’s a great time to sell. My eBay sales are up 10% this year.
