Here is a picture of one of the sunflower heads that I harvested. I have just over one dozen of them. Notice the regular size marker in the picture for perspective. They are massive.
More garden news: The harvest is pretty much done. Today I picked the two watermelons and found out that they have white flesh not red. Interesting. The tomatoes and a few beans are all I have left. I have torn up everything else and am letting it compost in place to create great dirt for next year. Many lessons were learned this year, the main one being that plants will get as big as the seed packet states. Make sure tomatoes are farther apart than necessary because they grow huge. Plant lettuce as a border along a path, that way you do not have to stoop through the garden to get to it (since you are out picking it almost daily). Have defined paths and do not plant up next to them or the plants grown them over. Companion planting works but be sure to give things the space they need.
