Crabgrass is an annual weed. In flower and vegetable gardens, hoeing and hand pulling are the best control options. When cultivating the garden, avoid deep tillage. The roots of many vegetables and flowers grow near the soil surf
The best way to prevent crabgrass infestations in lawns is to maintain a thick, healthy lawn through proper mowing, irrigation, and fertilization. Crabgrass will have a difficult time germinating and surviving in a dense stand of turfgrass.&
Mealybugs on houseplants are difficult to control. Unless the plant is particularly valuable, it’s often best to throw away the infested plant before the insects spread to other houseplants. The standard remedies for houseplant pests c
Nimblewill (Muhlenbergia schreberi) is a warm-season perennial grass. Nimblewill is a thin, wiry grass that is pale green or gray-green. It spreads by aboveground shoots or stolons, often forming circular spots in the lawn.&nb
Perennial broadleaf weeds die back to ground level in fall but send up new growth in spring. These weed species have leaves that are wider and are typically botanically classified as eudicots (dicots). Perennial weeds reproduce by seed

Perennial grassy weeds die back to ground level in fall but send up new growth in spring. These weed species have long thin leaves with parallel veins. Perennial weeds reproduce by seeds or may spread by creeping above or below ground
Perennial grassy weeds die back to ground level in fall but send up new growth in spring. These weed species have long, narrow leaves with parallel veins. They are often in the Poaceae (grass) family or a closely related family and are
Poison ivy (Toxicodendron radicans) is a native vine common to woodland areas but found frequently growing in gardens and along fence lines. This vine causes an allergic reaction (dermatitis) in most people when their skin comes in
“Water grass” is an ambiguous name. Several plants are occasionally referred to as water grass. Two common lawn weeds that are sometimes referred to as “water grass” are crabgrass and yellow nutsedge.
Weeds compete with asparagus for light, water, and nutrients and will reduce asparagus yield and quality if not controlled.
Keeping ahead of weeds and controlling them when they are small is essential for good weed management. This requires persistence throughout the entire growing season to remove weeds as they emerge.
Herbicides can be used to supplement cultivation, hand pulling, and mulches.
Cultivation, hand pulling, and mulches are the primary means to control weeds in the home garden.
Weed control is essential to insure optimal plant growth and fruit production. Weeds compete with the strawberry plants for water, nutrients, and sunlight. Weeds also reduce air circulation which results in fruit and foliage staying we
Cultivation and hand pulling effectively control most annual weeds. It is very important to destroy these weeds while they are small before they produce thousands of seeds, guaranteeing a weed problem for many years in the future.
Weedy vines are fast growing plants, getting very large in a relatively short amount of time often climbing and covering other garden plants. If left to grow, they can smother other plants blocking out light and killing the desirable plant.
White clover (Trifolium repens) is a creeping perennial. It is a common plant in many Iowa lawns because it is a prolific seed producer and adapts well to mowing and other lawn care practices. Its presence is often a sign of l
Woody weeds are trees and shrubs that have woody plant tissue. They are perennial and typically classified as eudicots, although some may belong to other plant groups like gymnosperms (conifers). Examples of woody weeds include tr
Jack-in-the-pulpit (Arisaema triphyllum) seeds can be sown directly outdoors or started indoors. Harvest the cluster of berries as soon as they turn red in late summer. Each berry usually contains 4 to 6 seeds. Remove th
Some orchids bloom annually, others will bloom continuously. Providing all the proper environmental conditions (light, temperature, water, fertilizer, etc.) will allow for the orchid to bloom well.
Mosses in lawns are usually a sign of poor growing conditions. Turfgrasses have a difficult time growing in heavy shade, compacted soils, or other poor sites. However, mosses are adapted to a wide range of environmental conditions.&nbs
Mushrooms are the reproductive or fruiting structures of fungi.
Early spring is an excellent time to divide:
Garlic requires more fertilizer than many vegetables. Apply and incorporate 1 to 2 pounds of an all-purpose garden fertilizer, such as 10-10-10, per 100 square feet of garden area prior to planting.
A weed is any plant growing out of place.
A weed is simply a plant out of place. By this definition, any plant could be a weed if growing in a location where it is not wanted.
Careful observation of your seedlings will help you determine if the light levels are appropriate. Seedlings that are not receiving enough light will stretch and lean towards the light source. Use a brighter fixture that provides more
Home gardeners can lower their soil pH by adding sphagnum peat moss to the soil. (The pH of sphagnum peat moss generally ranges from 3.0 to 4.5.) When planting azaleas and rhododendrons, dig a wide, shallow hole. Backfill with a
Home gardeners can lower their soil pH by adding sphagnum peat moss to the soil. Sulfur can also be used to acidify the soil. Sulfur should be incorporated into the soil a year before planting as it reacts slowly with the soil. A
