Yard and garden – late summer lawn care

AMES, Iowa – A lot of activities can be done in Iowa in late summer and early autumn to help grass grow well. Most of the meadows in Iowa are Kentucky Bluegrass and other cool season grasses.

Proper mowing, cultivating, ventilation, weeding control and fertilization can grow late in the growing season, lush green, beautiful, cool grass. Aaron Steele, a consumer horticultural expert at Iowa State University Extension and Access, will be providing summer grass care advice this summer at “Yard and Garden”.

What are the best harvesting practices for the fall?

During the harsh, hot summer months, lawns range in height from 3.0 to 3.5 inches. Harvest weather conditions encourage better growth. Decrease the harvest height by 2.5 to 3 inches in September. Keep mowing the lawn until the end of October / early November. When cutting grass, never remove more than one-third of the total leaves.

How do I control my thin and small lawn?

From mid-August to mid-September is the best time to regenerate the lawn. Planting grass in late summer has many benefits for spring seed. During the cool season, grass seeds grow rapidly in tropical soils in late summer. Once the grass has sprouted, warm days and cool autumn evenings encourage faster grass growth. There will also be less competition for weeds in late summer and autumn, with fewer weeds.

Harvest grass from 2.0 to 2.5 inches in height to reduce competition from established grass. Successful outsourcing requires good seed-to-soil contact. Major air conditioners, vertical scissors, and sawmills can be used to ensure good soil-to-soil contact.

After sowing, keep the top 1 inch of soil moist and easy to apply. If part of the crop is to be uniform, most grasses need to grow. When grass seedlings reach a height of 1 to 2 inches, gradually reduce the frequency of irrigation, but water more deeply.

Why and how should I mow my lawn?

September is the best time to cultivate grasslands in Iowa. Air conditioning reduces soil congestion, improves the movement of water and nutrients in the soil, and prevents its accumulation.

Ethernet grass with main air vent. Core air conditioners have hollow metal tubes or tins that remove dust plugs. Avoid sharp objects that can easily hit holes in the ground. Core air conditioners can be rented from hardware or machine rental stores or the service can be provided by a professional lawn care company.

Remove soil cores that are approximately three quarters of an inch in diameter and 3 inches long. For best results, ventilate fields when the soil is moist. When the soil is dry or wet, avoid adding air. Tubes or tubes cannot penetrate deep when the soil is dry and may stick to the soil when it is wet. Properly ventilated lawns should have 20 to 40 holes per square foot. Since most major air conditioners do not remove the right vent holes in one pass, multiple passes are often necessary. After ventilation, pull a rug or heavy fence material to the ground to break up the soil. If grass cover is small, use a strong plug to break the soil.

When and how should I apply weed control in my lawn?

In small areas, weeds can be controlled by dragging and digging. This method is best done after a shower of rain or deep water. Unfortunately, dragging and digging are often ineffective against entrenched weeds.

In many cases, weeding is the only practical method. Many annual weeds, such as dandelion, clover, amoebae, and planets, are better controlled in Iowa from late September to early November. Effective broad leafy vegetables include 2,4-D, MCPP, MCPA, dicamba, triclopyr and others. The most effective broad-based herbicides contain a mixture of two or three herbicides, since not all compounds can control all weeds. Broadly leafy greens can be applied as a liquid or as a particle. Do not use herbicides until new grass has been cut at least twice. Herbicides should be used in accordance with the general label guidelines.

For many years, grasshoppers, such as quackgrass and long fescue, had few options for control. If digging or dragging is not practical, the most effective herbicide is the non-selective herb glyphosate (Roundup). Indestructible herbicides kill almost all the plants (weeds and weeds) on which the wound is applied. Spot treats weeds that last a long time. More than one application may be needed to kill weeds that are difficult to control. Always apply herbicides when the winds are calm and do not damage desirable plants and when temperatures are low.

Although the annual weeds are better controlled during the harvest season, the annual broad and weed control, such as crabgrass and bow knotweed, is best done in early spring with pesticides.

When should I apply fertilizer to my lawn?

Fertilizer applications can be made in mid-September and again in late October / early November. In mid-September, fertilizer promotes moderate shoot growth and helps to fertilize grass cover. Fertilizer application in late October / early November (during the last harvest) promotes root growth and early green next spring. Apply 1 kg of real nitrogen per 1,000 square feet using a slow-release fertilizer for each application.

For low maintenance fields, only one application is required at the end of October / early November. High maintenance grasses can use the third application at the same rate in the spring (April or May).
