As much as I'd like to start planting peas the soil tells me no. I'm in the Saint Paddy's day region of thinking and what generally happens is peas rot if planted too early. Wake up early or stay up all night long and look at the soil..place it in your hand..squeeze it...does it break up like cake? if so get some frosting but if it stays together or worse feels like pieces of concrete wait. Also remember last oh way back when January even and how the soil was read to work in the latter part of the month. It's froze back up since. It was frozen this morning and then okay in the afternoon but any clay regions were not quite Duncan Hines. Frost seeps... frost is water in another form and it'll find it's intended victim. Visit an old farmer or something and ask them and see what they say chances are they say their gut feeling says wait. All it takes is one cold week or even day if it's really cold...and all dead

That's what my first thoughts were. But if the trees are planted at 10' spacing on the row N/S it seems that some of them will be shaded somewhat after they grow a few years. Planting with the rows E/W there should be less shading with the rows 20' apart it seems to me. It probably won't make a bit of difference anyway. We've had some nice weather for a change and I was out trying to figure a plan while pulling a few winter weeds.

Did you pay your deposit on a credit card? If so, and you have a written estimated delivery date on your sales order, you may be able to cancel via a chargeback through your credit card company. This is a civil matter, there are no 'laws' that will assist you on an issue such as this. Quite frankly its not worth the hassle to try to begin a legal action in civil court. '30 days' delivery on any special order upholstery should set off alarm bells. While it can be done, its rare. Shipping time alone is typically 7 to 10 days in and of itself. At this point you are what....3 to 4 weeks out? (if you can believe them). My advice is to just sit tight and be patient a bit longer.

Pea vines certainly won't "support each other", though it's not a disaster to have them grow in what is basically a pile. They'll grow. The advantage of trellising with rows, besides easy picking, is sunlight. Growing in a pile doesn't take advantage of the sunlight. Trellising spreads them out to capture the most sunlight. The leaves inside the pile will be largely shaded. Peas don't like heat, but they do like sun. That's evident, because peas will phototrope strongly in the direction of sunlight. Of course, by the same token, all vegetable plants might do better trellised, for the same reason, but peas make it easy. because they themselves are vining and climb readily.
