@Tere Spinach beet is new to me. Investigating (i.e. googling) it seems to be similar to chard but with a flavor more similar to spinach. I found several sources for seed - I may try this next year. Your garden is impressive, especially the fruit.
As of today all the irrigation system is in - both in the main garden and in the greenhouse. I don't install the irrigation in the main garden until after I plant because I worry about clogging the the drip tape with dirt as I make furrows and cover seeds. Now I can put in the tomato seedlings that are screaming their need for bigger places for their roots. And plant cukes and squash. Then I can move to maintenance.
