You won't be too late for warm season vegetables. I would buy tomato plants not start from seed unless you can start them inside where you are. I think I would want to get the fruit trees in the ground even though there is a risk. You are going to have to skip the early stuff. If you were home at all even to stop by you could scratch up a small spot for lettuce and radishes and just throw some onions sets on the top of the ground because they are cheap and want to grow.

I agree with Helen. You might want to "outsource" growing your vegetables from seed and this year buy your veg plants. A good mulch, buying true summer vegs, and you should be okay. That said, I'd definitely plant zucchini in late May. And as Helen said, onions.

I would think the hardest part of this would be finding good plants that late. Possible to buy where you are and transport? We once moved and brought 15 potted plants in the back seat of our sedan, along with a Labrador puppy, from Pennsylvania to Massachusetts, so it Can Be Done. Good luck.

Thanks for the responses. I'm halfway across the country, so there's no chance of dropping by to scatter some seeds. My schedule is up in the air about my return (I don't even know for sure whether we'll drive or fly back), so I'm just praying we'll still do OK with the garden. We just bought the house last year so we're just getting it established. We had a decent garden last year and bigger plans this spring, but sometimes fate has other ideas.

I am in Cedar county, closed on property on JUne and started garden about July 20. Still had a good garden, nice squash and beans, a few tomatoes and when it got cooler....lots of lettuce,radishes, swiss chard,collards and kale.
Don't give up.

Check the maturation date on seeds like sweet corn, squash, etc. but I am betting you still have time for a good late garden.The longest time required for most is between 100 and 120 days. So figure time planted to time of frost and you will know what you are dealing with.
