WSU extension Q and A: June 11, 2011

Q. Is it too late to plant corn?A. No, corn can be planted anytime from the beginning of April through the middle of June.Q. Now that school is out my kids just decided that they would like to join 4-H and exhibit at the Benton-Franklin County Fair. Can they still do this?A. The Extension office accepts enrollments year-round, but the 4-H year starts Oct. 1 and ends September 30. Your kids must be enrolled by May 1 to be eligible to exhibit in a 4-H department at the fair. However, if a youth has not enrolled by the May 1 deadline, they still can exhibit under the open youth departments. Call the Franklin County Extension office at 545-3511 for more information.Q. How long do I have to wait after applying Roundup in my garden before I can plant?A. The best answer for that is to check the label. There are a number of different formulations of Roundup and glyphosate products. Roundup Weed and Grass Killer Super Concentrate and Roundup Ready-To-Use Weed & Grass Killer Plus products indicate that "ornamental flowers, trees, and shrubs may be planted one day after application. Lawn grasses, herbs, vegetables, and fruit may be planted 3 days after application." However, Roundup Extended Control Weed and Grass Killer Plus Weed Preventer II is only for use around "driveways, sidewalk cracks, patios, paths, tree rings, mulched areas and along fence lines where any plant growth is undesired." So whichever glyphosate (now available under various product names) or Roundup product you chose to use, read and follow the label directions when using it in your landscape or garden.Q. I received several half-gallon canning jars from my grandmother. Where can I find processing directions for these jars? All I see in my canning guides are pint and quart jar recommendations.A. The only foods that can be safely canned in half-gallon jars are acidic fruit juices, such as apple and grape juice. There are no processing times for other fruits or vegetables. If you do plan to use the jars to process fruit juices, you will need a very large pot. When processing in the water bath canner, jars should be covered with 1 to 2 inches of water. It will take a tall pot to cover the half-gallon jars.* Questions should be called in to the WSU Extension offices in Kennewick at 735-3551 or Pasco at 545-3511.
