Iris trifecta — It’s time to divide irises. That means it’s time for the members of the Wichita Area Iris Club to divide their irises at home and at Botanica and to sell the divisions at their annual iris sale next weekend. Before that, there will be a lunchtime lecture at Botanica on Wednesday about the irises being grown there. See information about the lecture and sale below.
Dividing irises every three to five years rejuvenates them and increases flowering, Ward Upham of K-State says. Late July through early August is the best time to do it. It’s pretty easy to dig the fairly shallow clumps; use a sharp knife to cut the rhizomes apart so that you have a fan of leaves and a section of rhizome in each division. If a rhizome has borer damage that’s not too severe, you can remove the borers and replant. If a rhizome has a mild case of soft rot, you can scrape out the bad tissue and leave the rhizome to dry in the sun before dipping it in a 10 percent solution of bleach. Rinse the rhizome with water and allow it to dry again before replanting.
To replant divisions, cut the leaves back by two-thirds. Remove weeds from the planting area and fertilize according to soil test recommendations or with a complete fertilizer, such as a 10-10-10, assuming the area has not been heavily fertilized in the past. Apply the fertilizer at the rate of 1 pound per 100 square feet and mix it in 6 inches, Upham says.
When tomatoes need shade — If you have a tomato plant that lost leaves to disease, hail or hornworms, tomatoes on the vine could suffer from sunscald, Upham says. Sunscald causes a light yellow to white sunken spot that eventually can let in black mold, causing the tomato to rot. You can shade exposed fruit with cheesecloth, Upham says. Remove tomatoes that are already scalded to encourage more fruit to set. Tomatoes with only a little sunburn can be used if the damaged areas are cut out, he says.
Plant — Green beans, cabbage, carrots, broccoli, endive, cauliflower, beets.
