Cooling off — Tropical plants shouldn't consistently be out in temperatures under 50, but it's hard to bring them in when days are so warm. Keep an eye on the forecast and on the plants. And keep watering; the wind has been drying plants out.
Natural needle drop — I noticed that needles on some pine trees were turning yellow this week, and that is natural — as long as the needles are the older needles on the interior of the branches. The needles will turn brown and then drop, says Ward Upham of K-State. It's a natural occurrence that is more noticeable in some years than others, he says. Just be sure that the needles on the tips of the branches look fine and that there is no banding or spotting on the needles that are turning yellow. If you do see spots or bands, take a sample to the Extension Service, Upham says.
Prepare for fruit planting — I always love Upham's instructions for preparing for fruit planting in the fall. It can be applied to any other type of planting you may envision as well:
"Grass areas should be tilled so grass does not compete with the fruit plants for soil moisture and nutrients. Have the soil analyzed for plant nutrients. Your local K-State Research and Extension agents have information to guide you in taking the soil sample (in Sedgwick County, the phone number is 316-660-0100). From that sample, the agent can provide recommendations on what and how much fertilizer to add to correct nutrient deficiencies. Organic materials such as compost, grass clippings, leaves, hay, straw or dried manure, can be tilled into the soil to help improve its condition. Time and weather conditions generally are more suitable in the fall than in the late winter and spring for preparing soil. If fruit plants can be set by early April, they will have developed a stronger root system to support plant growth than they would if planted later."

Small sweet potatoes — Sweet potatoes should be harvested no later than the first fall freeze, but if you prefer smaller sweet potatoes, you can dig a hill anytime to see if they're the size you want, Upham says. Because the tubers can be nicked in the harvesting process, they should be cured to heal those wounds and improve flavor and texture, he says.
To cure, "place the roots in a warm, humid location for five to 10 days immediately after digging. A location with a temperature around 85 to 90 degrees is ideal. A space heater can be used to heat a small room or other area. Raise the humidity by placing moist towels in the room.
"Sweet potatoes should be stored above 55 degrees. Storage at temperatures below that injures the roots, shortens storage life and gives them an off flavor."
Family of Four Garden —The Swiss chard was treated last Saturday to get rid of caterpillars, so the harvest of it was skipped this week in the Family of Four garden at the Extension Center. But a pound of peppers valued at $1.50 was picked. "We are about $21 from covering all seed costs (including leftover seeds) as well as the costs of building a raised bed, buying irrigation, row cover fabric, a light stand, pots and potting soil for seed starting, and fertilizers," extension agent Rebecca McMahon says. "We should at least break even on the garden this year, so in future years we will only need to count the cost of seeds, fertilizers and other miscellaneous expenses."
Plant — Fescue grass seed, by Oct. 15; tulip, daffodil, crocus and other spring-flowering bulbs, and garlic, through October; pansies, asters and mums.
