July Garden Calendar Tips
Note: Letters and numbers following the tip refer to Purdue publications; other reference links on the topic may also be supplied.
- First Week: White patches of powdery mildew may be seen on the leaves of garden phlox. To control, plant resistant cultivars, thin emerging shoots in the spring or use a fungicide (BP-5). <https://www.extension.purdue.edu/extmedia/bp/bp-5-w.pdf>
- Second Week: This is often the toughest time of the year to establish a lawn. Wait until mid-August to seed (AY-3).
- Third Week: Continue to provide roses with proper water, fertilizer and pest control management as needed (HO-128).
- Fourth Week: Continue harvesting raspberries. Remove raspberry canes that fruited after harvest is complete (HO-44).

AAS Announces 3 National Winners for 2018
All-America Selections (AAS) has recently announced their first batch of 2018 national award winners: Ornamental Pepper Onyx Red, Sweet Corn American Dream and Cocktail Tomato Red Racer. We will grow all three national winners in the Purdue Extension-Marion County Demonstration Garden in 2018.
Onyx Red Ornamental Pepper has black foliage similar to the 2006 AAS showstopper Black Pearl. However, Onyx Red is a compact, well-branched plant growing only about 6 inches tall in a pot or 8-10 inches tall in the garden. Recommended garden spacing is 6-8 inches. Onyx Red produces beautiful three-eighths inch black fruit that eventually turn red. The plant grows best in full sun and no deadheading or staking is required.
American Dream Sweet Corn edged out 1988 AAS award winner Honey ‘N Pearl. The bicolor kernels on the 7-inch ears are very tender and super sweet with excellent bite depth. American Dream matures slightly earlier and has excellent germination. Plants grow 6-7 feet tall and the corn is ready in 77 days.
Red Racer Cocktail Tomato is a small uniform round red tomato with classic tomato flavor. They grow in clusters but are larger than cherry or grape tomatoes – the two-ounce fruit are 1.5 inches in diameter. Tomatoes are ready to eat in only about 57 days from transplanting. The compact determinate plants are suitable for containers or plant about 2 feet apart in the garden. Plant height is about 3 feet so training is optional. Plants can produce 68 tomatoes per plant. Red Racer has the following disease resistance: Verticillium wilt, Fusarium wilt (1 and 2), nematode, tobacco mosaic virus, and gray leaf spot.
