Hey Bucktales.

Don't worry about the 'gus shading anything out. The summer sun is so high that it really is not a worry. Besides, your lettuce might appreciate it come the hottest part of summer.

You might want to consider wide rows. You have about 2.5 feet between rows. Once those tomatoes fill out there will not be much room to squeeze in to get to your beans, and you can forget about walking between the peppers and the tomatoes.

However, if you planted the tomato row a foot closer to the pepper row, and treated it as a single wide row, you would have more room between them to work and you could reach the tomatoes from either side. You could even inter-plant all those onions within that row, saving more space and giving you another row to work with where the onions are now.

Yes, your early peas will be finished in time to get the cucumbers in and have a good crop. Start the cucumbers indoors before the peas are ready for havest; start the cucumbers in peat pots and plant the pots in the garden(be sure to bury the lips of the pot so they don't wick moisture from the soil)--that way you can move the season along and get your cucumber harvest quicker.

If you find you have empty spaces that you didn't plan for, you can fill the spaces in with quick-maturing crops (sometimes called catch crops). Also use quick-maturing crops early and late in the season around your main crops.

Thanks for the feedback all. I was going to make that trellis one big 12' long one. Would it be better if I made it 3 separate 4' ones so things aren't "running into one another", so to speak?
