Anyone have a suggestion for low cost plant labels that won't fade out before the end of the summer?
I gave up on markers. For my tomatoes this year, I did this: make a map of what is in the garden on the computer, and print it out. Then I take a picture of map with my phone so that I always have it.
The problem with that is: map made, stuff in garden. Late frost takes out a bunch of stuff, here and there. Replant with purchased plants that are NOT the same variety. I had to redo the map, and instead of having all the Ace 55 in a row, I had some Supersteak interspersed.

Yeah, it got confusing.
With raised beds, I try to have it laid out in sections. In the bean bed, the west end is Dragon Tongue, the east is a purple bean. Once they start growing, it's easy to tell which is which, as the purple beans have a purple cast to the leaves.
I don't know if this would help, but how about coating the sharpie marked marker with clear nail polish, or polyurethane?
I looked online and it said the EWO should be planted 1 per square foot. That is a really big difference from the regular onions I have planted in the past. What is your recommendation for spacing of EWO when planting? Does it make a difference if you plan on eating only the greens or the whole onion?
Yes, 1 per sf is about right. The first year, it may look a little sparse, but my EWO bed is jammed full, and has been since the second year.
This is from summer 2022. My 3rd (?) year with EWOs.
Also, just to make sure, I think I am supposed to plant the bulbs before winter, about 2 inches deep, so they grow early in the spring next year. Some YouTube videos I watched said you cannot keep EWO bulbs very long because if they dry out, they die and will not grow.
Yes. You can plant them now, if you're close to frost. They need to be in the ground before it freezes. They get roots started, "get used to their home," so to speak. 2-3" deep, and then cover the bed with 3" of mulch. I did that the first year, and when they started to sprout in the spring, I pulled the mulch (compacted by the snow over winter) away from the leaves poking up.
Our late freeze last May wilted the leaves that were up, but everything bounced back just fine.
I also failed, but I used small test batches, so I can try something different tomorrow.
Instead of thinking of it as failure, think of it as learning a way that didn't work. Adjust, adapt, retry.
