Before spending money on something called "soil" take a good look at the soil you already have. It does little good to add to bad soil some even really good soil but even bad soil with the proper amendments can be made good and often at lower cost then buying some kind of "soil". Contact the people at your local office of the Washington State University Cooperative Extension Service about having a good, reliable soil test done so you know your soils pH and present level of certain nutrients and then dig into your soil with these simple soil tests, 1) Structure. From that soil sample put enough of the rest to make a 4 inch level in a clear 1 quart jar, with a tight fitting lid. Fill that jar with water and replace the lid, tightly. Shake the jar vigorously and then let it stand for 24 hours. Your soil will settle out according to soil particle size and weight. A good loam will have about 1-3/4 inch (about 45%) of sand on the bottom. about 1 inch (about 25%) of silt next, about 1 inch (25%) of clay above that, and about 1/4 inch (about 5%) of organic matter on the top. Drainage. Dig a hole 1 foot square and 1 foot deep and fill that with water. After that water drains away refill the hole with more water and time how long it takes that to drain away. Anything less than 2 hours and your soil drains too quickly and needs more organic matter to slow that drainage down. Anything over 6 hours and the soil drains too slowly and needs lots of organic matter to speed it up. 3) Tilth. Take a handful of your slightly damp soil and squeeze it tightly. When the pressure is released the soil should hold together in that clump, but when poked with a finger that clump should fall apart. 4) Smell. What does your soil smell like? A pleasant, rich earthy odor? Putrid, offensive, repugnant odor? The more organic matter in your soil the more active the soil bacteria will be and the nicer your soil will smell. 5) Life. How many earthworms per shovel full were there? 5 or more indicates a pretty healthy soil. Fewer than 5, according to the Natural Resources Conservation Service, indicates a soil that is not healthy. which can guide you in making the soil you have into a good, healthy soil that will grow strong and healthy plants better able to ward off insect pests and plant diseases.

Peegee, good thought, the deck roof does have skylights. It's still really dark. They put quite a lot of recessed can lights in that kitchen too, still dark. What if I sprung for a different counter material on the island only, in addition to painting it? Worth thinking about? Or would I just be throwing money away? There's a cooktop in the island that takes up most of it, so I was thinking of putting a large, wood cutting board next to it so kind of cover the counter a little. Maybe that would be enough.

Purple-flowered cultivars of Autumn sage (Salvia greggii) and bearded or Louisiana iris do well in north Texas. All good for small gardens and pretty fail proof. Echinacea purpurea 'Magnus' and other coneflowers are also reliable perennials here. 'Jackmanii' is another purple clemantis that does very well in the area. For shade, American beauty berry (Callicarpa americana) displays beautiful purple berries this time of year that the birds really appreciate.
