Garden Spiders

0
Though some consider spiders to be unwelcomed, they are a valuable resource for pest control.
The yellow garden spider is commonly found in our Kansas gardens. The body is one-inch long and has yellow markings on the dark-colored abdomen. Legs of the garden spider are black with a yellow or reddish band.
The banded garden spider is similar in size with yellow and white bands marking the legs and abdomen. The legs have black and orange bands.
These two varieties of spiders are types of orb weavers and construct large, circular webs often in bushes, tall grasses and other areas with high insect populations. These spiders are not dangerous to humans and should be left alone to allow them to continue feeding on pests in the garden.

Ornamental Sweet Potatoes

0
Ornamental sweet potatoes are mostly valued for their attractive foliage as it drapes down the sides of containers and spreads over the ground within planters. As with other ornamental vegetable varieties, though ornamental sweet potatoes are edible, they are grown for their aesthetic value. Consequently, the flavor quality of ornamental varieties is often lacking. In the case of ornamental sweet potatoes, the tuberous roots are much more bitter than the edible counterpart. If you choose to consume them, follow the curing instructions in this newsletter.
Ornamental sweet potatoes can be overwintered by digging them just before the first frost and storing until it’s safe to plant in the spring. Remove the above ground growth and keep the roots in moist peat moss in a cool, dark room. Alternatively, the entire plant can be moved indoors and kept as a houseplant during the winter. Check the plant first for signs of disease or pests. Cut the vines back to about one-foot and carefully transplant into the desired container. Keep the plant in a space with plenty of natural light until warmer weather returns in the spring.

Vegetable Crop Rotation

0
Crop rotation is the recommended practice of changing the location of plants within the same family each growing season. Plants within the same family are often susceptible to similar pests. They also have similar nutrient requirements. By planting crop families in different areas of the garden each season, a common host plant is removed. Pests that overwinter in the soil or debris are not able to continue their life cycle which prevents the population from growing exponentially. Additionally, the varied root system depths and nutrient requirements prevents nutrient depletion in the soil. Often, cabbage, peas, lettuce, onions and other cool-season crops have more shallow roots. Warm-season crops tend to have a more extensive root system.
To plan your crop rotation draw a diagram of your vegetable garden now while you remember where everything is. Next year, as you making your planting plan, reference this sketch and alternate locations for each plant family. For example, in the area where you have tomatoes this year avoid planting anything from the Solanacaeae family (eggplant, pepper, potato) next year. If you planted bush beans this year, be sure to avoid planting anything from the fabaceae family (lima beans, peas, pole beans, etc.) in the same location next year.
