The month of September signals the prime time to fertilize your tall fescue or Kentucky bluegrass lawns. If you could only fertilize your cool-season grasses once per year, this would be the best time to do it.
These grasses are entering their fall growth cycle as days shorten and temperatures moderate. Cool-season grasses naturally thicken up in the fall by tillering (forming new shoots at the base of existing plants) and, for bluegrass, spreading by underground stems called rhizomes. Consequently, September is the most important time to fertilize these grasses.
Apply 1 to 1.5 pounds of actual nitrogen per 1,000 square feet. The settings recommended on lawn fertilizer bags usually result in about 1 pound of nitrogen per 1,000 square feet. We recommend a quick-release source of nitrogen at this time. Most fertilizers sold in garden centers and department stores contain either quick-release nitrogen or a mixture of quick- and slow-release. Usually only lawn fertilizers recommended for summer use contain slow-release nitrogen. Any of the others should be quick-release.
The second most important fertilization of cool-season grasses also occurs during the fall. A November fertilizer application will help the grass green up earlier next spring and provide the nutrients needed until summer. It also should be quick-release applied at the rate of 1-pound actual nitrogen per 1,000 square feet.
Have you been picking tomatoes for weeks? This time of year, our gardens really start taking off. If you have excess produce, we have a great recipe for you! This video shows tomato plant care tips, harvesting information, and a delicious salsa recipe!
Fall is an excellent time to plant trees and shrubs in your landscape. During this time of year soils are warm and moist, creating the perfect environment for root growth. Planting in early September through the end of October allows roots to become established before the ground freezes.
Are you sad gardening season is coming to an end? You might not be thinking about planting vegetables in September, but fall is the perfect time to plant garlic! Just like tulips and daffodils, garlic is planted in the fall and harvested in early summer. Watch this video to learn more:
Strawberry beds might be done producing for the summer, but that doesn’t mean we can forget them. An August application of nitrogen on spring-bearing strawberries is important in order to increase the number of strawberries produced next spring. Plenty of daylight and warm temperatures during June, July and August promotes the growth of new runners, or daughter plants. As daylight hours dwindle and temperatures grow cooler in September and October, fruit buds for the next year’s fruit crop develop. To get a good berry crop next spring, it is important for strawberry plants to be vigorous during this period of fruit bud development.
Nitrogen, applied mid-August, will help promote fruit bud development. A general application rate is ½ to 3/4 pound of actual nitrogen per 100 feet of row. The nitrogen may be in the form of a fertilizer mixture such as ammonium phosphate or 12-12-12, or in a fertilizer containing only nitrogen such as urea or ammonium nitrate. Some specific examples would include:
Iron + (11-0-0) at 6 pounds per 100 feet of row.
12-12-12 at 5.5 pounds per 100 feet of row.
Nitrate of Soda (16-0-0) at 4 pounds per 100 feet of row
Ammonium sulfate (21-0-0) at 3 pounds per 100 feet of row
The hot weather we have had recently not only interferes with flower pollination but also can affect how quickly fruit matures. The best temperature for tomato growth and fruit development is 85 to 90F. When temperatures exceed 100 degrees, the plant goes into survival mode and concentrates on moving water. Fruit development slows to a crawl. When temperatures moderate, even to the low to mid 90s, the fruit will ripen more quickly.
Tomato color can also be affected by heat. When temperatures rise above 95 degrees F, red pigments don’t form properly though the orange and yellow pigments do. This results in orange fruit. This doesn’t affect the edibility of the tomato, but often gardeners want that deep red color back.
So, can we do anything to help our tomatoes ripen and have good color during extreme heat? Sure, there is. We can pick tomatoes in the “breaker” stage. Breaker stage tomatoes are those that have started to turn color. At this point, the tomato has cut itself off from the vine and nothing will be gained by keeping it on the plant. If tomatoes are picked at this stage and brought into an air-conditioned house, they will ripen more quickly and develop a good, red color. A temperature of 75 to 85 degrees F will work well.
