Animal Fencing Tucson AZ

Fencing is the only sure-fired way to keep wild and domestic animals out of a prized garden long term. Although it can be expensive for large animals such as deer, it may be the only way to protect your yard from costly damage.

Animal Trapping Tucson AZ

If you've tried repelling, excluding, and scaring away a pest animal and it's still causing problems, you can trap and release it, or use a lethal trap. Trapping is an effective way to remove a specific pest animal, but isn't useful against a large local population over the long run.

Anthracnose Tucson AZ

This fungus occurs worldwide. In North America it is especially troublesome in the humid eastern part of the continent. Beans develop round, black, sunken spots on pods and stems. Veins on leaf undersides turn black.

Aphids Tucson AZ

Aphids are found throughout the United States. These small, soft-bodied insects may be pale green, pink, black, or yellow, depending on the species. Some stages of the life cycle are winged, others wingless.

Bermudagrass Tucson AZ

Bermudagrass ( Cynodon dactylon ) is a terrible nuisance in gardens in the southern half of the United States. Improved turfgrass strains often behave themselves, but primitive forms are very difficult to control. It spreads in Tucson by creeping stems, underground stolons, and seeds.

Bindweed Tucson AZ

Bindweed ( Convolvulus arvensis ) is a perennial vine in Tucson with green, arrow-shaped leaves and 1-inch-wide morning glory-type flowers that may be pale pink or white. Extremely persistent, bindweed produces new plants from seeds and from buds on its roots. Bindweed roots can spread 30 feet from the parent plant.

Birds Tucson AZ

Many birds are friends to the gardener, as they feast on harmful insects and weed seeds. But when they feast on our crops, we categorize them as pests.

Black Medic Tucson AZ

Black medic ( Medicago lupulina ) is a thrifty yellow-flowered clover that usually grows as an annual. Common in lawns and gardens around the world, black medic often colonizes dry, infertile spots where little else will grow. Plants stay close to the ground until they are ready to bloom. By the time flowers appear, the stems may be 6 to 26 inches long.

Broadleaf Plantain Tucson AZ

Broadleaf plantain ( Plantago major ) is found throughout North America, usually in compacted places in lawns or in garden pathways. A tap-rooted perennial, plantain becomes dormant in winter in Tucson, and new leaves appear in mid-spring.

Buckhorn Plantain Tucson AZ

Buckhorn plantain ( Plantago lanceolata ) is often called narrow-leaf plantain in Tucson. This European import eagerly moves into moist lawn areas, or colonizes edges where lawns and garden beds come together. New seedlings of this hardy perennial appear all season, and small ones are easy to pull when the soil is moist.

Buttonweed Tucson AZ

Buttonweed comes in two forms in Tucson, both of which can be persistent weeds in lawns. Annual common buttonweed ( Diodia teres ) has narrower, more pointed leaves compared to Virginia buttonweed ( D. virginiana ). Virginia buttonweed is more difficult to control because it is a perennial that grows back for several years. Pull young plants when the soil is moist.

Canada Thistle Tucson AZ

Canada thistle ( Cirsium arvense ) is a persistent perennial weed in the northern half of North America. It produces new plants from buds on its wandering roots, and by shedding thousands of seeds. Promptly remove this or any thistle with rosy pink blossoms from your property in Tucson.

Carpetweed Tucson AZ

Carpetweed ( Mollugo verticillata ) is an expert at colonizing moist places where shrubs, trees, and the lawn come together. Seeds germinate in late spring, and warm weather brings a rush of long, sticky stems studded with whorls of three to six leaves and small starry white flowers. Stems stay low to the ground in sun but may form 12-inch-tall mats in shade.

Cats & Dogs Tucson AZ

Man's best friends can also be your garden's worst enemy. An untrained dog can maul plants or dig up freshly planted bulbs, flowers, or your lawn. Cats won't do as much digging and damage in general, but they love to lie on freshly turned earth where your vegetable seeds were just planted.

Chickweed Tucson AZ

Chickweed ( Stellaria media ) is a widespread, hardy annual often found in moist, fertile garden soil in Tucson. In mild winter climates it begins blooming before winter ends. Edible but not very tasty, chickweed plants form dense 3-inch-tall mats of foliage studded with starry white flowers.

Chipmunks & Squirrels Tucson AZ

These furry rodents are regulars at many backyard birdfeeders and will also attack a variety of garden targets such as young seedlings, berries, fruits, and vegetables. They even have been known to decapitate flowers such as tulips -- seemingly just for fun.

Cinquefoil Tucson AZ

Cinquefoil ( Potentilla spp.) often sneaks into lawns in the eastern half of North America, where several species are native to open woodlands. The plants resemble strawberries, but the leaves are made up of five leaflets whereas strawberries (including weedy Indian mockstrawberry) have only three. Cinquefoil's leaves often are a medium to light green color.

Codling Moth Tucson AZ

Caterpillars bore small holes in the fruit, usually at or near the blossom end. Inside, the pinkish-white worms with brown heads feed on the flesh, leaving tunnels full of sawdustlike frass (droppings). Infested fruit often drops prematurely from trees in Tucson.

Controlling Slugs Tucson AZ

If there's one garden pest that's universally despised, it's slugs. Not only do they eat prized vegetables, herbs, and flowers at night while you sleep, but when you do catch them, they're so slimy and squishy that many gardeners won't even touch them, let alone kill them in Tucson.

Controlling Whiteflies and Aphids Tucson AZ

Few insect pests are more widespread than whiteflies and aphids. They attack indoor and outdoor vegetables, flowers, herbs, shrubs, and trees. They breed quickly, and once their numbers are high, they can damage leaves, stems, fruits, and even roots by sucking plant juices in Tucson.

Coping with Pest Deer Tucson AZ

Deer in rural areas are often more timid of human presence and activity than those in suburban areas, so different control methods may be effective. Your county agricultural extension service or local wildlife management office can give you the most accurate information about deer activity in your area in Tucson.

Corn Rootworm Tucson AZ

Striped and spotted cucumber beetles are close relatives. Larvae of these beetles are 1/2- to 3/4-inch-long, white wormlike grubs that tunnel into and feed on the roots of corn plants, making them stunted, yellow, and unstable in Tucson.

Corn Speedwell Tucson AZ

Corn speedwell ( Veronica arvensis ) seeds have a special talent for finding the one disturbed spot in an otherwise perfect lawn in Tucson. Suddenly, in late spring, a little green weed with triangular, deeply scalloped lower leaves appears bearing small blue flowers. Both the leaves and stems are fleshy. A cool-season annual, speedwell blooms heavily in spring, and a second generation sprouts in fall.

Coyotes Tucson AZ

Once confined to just the plains, this solitary canine is now found throughout the United States. Coyotes have learned to live with man by being active when man is not�when it's dark�and their presence may be more of a concern to pet and livestock owners. Since coyotes diet consists mostly of small animals and rodents, they could help your garden more than hurt it, but they can do their shar...

Crabgrass Tucson AZ

Crabgrass ( Digitaria species ) seedlings appear from mid-spring through summer in many types of soils in Tucson. This fast-growing annual needs only warm rain to coax seeds to life. Where crabgrass infestation is severe, apply an organic corn gluten herbicide product in spring, keeping in mind that it will inhibit the growth of all types of newly germinated seeds.

Cucumber Beetle Tucson AZ

There are two forms of cucumber beetle -- one striped and the other sporting a dozen black spots. Cucumber beetles are pests of far more plants than their name indicates in Tucson.

Curculio Tucson AZ

Dallisgrass Tucson AZ

Dallisgrass ( Paspalum dilatatum ) is a pasture grass from South America that has become an invasive nuisance in the southern half of North America.

Downy Mildew Tucson AZ

Various types of downy mildew fungi cause disease in a number of crops across North America. Irregular brown or yellow spots develop on the upper leaf surface; the lower leaf surface beneath these spots is covered with a hairy white or purple mold during humid weather.

English Daisy Tucson AZ

English daisy ( Bellis perennis ) is often grown as a colorful little perennial that blooms in shades of pink, but wild strains bearing white flowers with yellow centers can be persistent weeds in lawns. Often called lawn daisies, the plants survive mowing by holding their crowns close to the ground. The rosettes of rounded leaves block light to nearby grasses. Pull plants or gently dig...

Extending the Gardening Season Tucson AZ

Plant seeds of long-season crops indoors in pots before the last frost date in your area in Tucson. Start tomatoes, peppers, and eggplants 8 weeks early, cole crops about 4 to 6 weeks early, and vine crops 1 week early. Extend your harvest into fall by planting second crops of short-season vegetables, such as snap beans, peas, greens, radishes, cole crops, and turnips later in the season so they mature after you harvest the first crop.

Fire Ants Tucson AZ

Fire ants range in size from 1/8 to 1/3 of an inch, but their bite feels like they're much bigger in Tucson.

These tiny beetles earn their name by jumping like fleas when disturbed. There are many pest species with varying markings and colorations. The blue-black flea beetle shown here is most common in Tucson.

Flowers Tucson AZ

Although the procedure is simple, there are a few techniques that will improve your chances of being a successful flower grower.

Foxtail Tucson AZ

Foxtail ( Setaria species ) seeds germinate from late spring to fall in Tucson. This shallow-rooted annual grass prefers sun and grows so fast it can shade out small flowers and vegetables. Closely related species vary in height, from 2 to 5 feet, and all produce furry, bottlebrush seedheads.

Gardening Equipment Tucson AZ

Grasshopper Tucson AZ

Pest grasshoppers can be as large as 3" long. There are many species of grasshoppers in North America, and about 30 of these qualify as garden pests in Tucson. They are most damaging in the center of the continent in a band extending from Minnesota and Montana in the north to Texas and New Mexico in the south.

Hawkweed Tucson AZ

Hawkweed ( Hieracium spp.) often forms dense colonies in areas of the lawn where the soil is infertile and acidic. A hardy perennial found throughout North America, hawkweed holds its rosettes of wildly hairy leaves close to the soil surface, safe from mower blades.

Horsetail Tucson AZ

Horsetail ( Equisetum arvense ) has been around in Tucson since dinosaur days. It is a common perennial weed in the northern half of North America, especially in moist soils. Upright stems with cone-like tips bear spores, but horsetail owes its staying power to spreading roots.

How-To Project: Growing Plants on Trellises Tucson AZ

A trellis covered in morning glories brightens up an old shed. Instead of imagining your garden in Tucson as a flat canvas, look at it as a three-dimensional space.

Indian Mockstrawberry Tucson AZ

Indian mockstrawberry ( Duchesnea indica ) grows into a dense ground cover in moist shade, and often invades shady swaths of lawn in all except the dry mountain states.

Quackgrass Tucson AZ

Quackgrass ( Agropyron repens ) is a persistent perennial weed in the northern half of North America. Plants usually appear in broad, 1- to 3-foot-tall clumps in Tucson, because new shoots grow from wandering underground rhizomes.

Raccoons Tucson AZ

Raccoons are nocturnal animals that are thriving thanks to increased human contact, as anyone with an unsecured dumpster or trash can will attest. Wild populations prefer areas with trees and water nearby.

Ragweed Tucson AZ

Ragweed ( Ambrosia artemisiifolia ) is a native, warm-weather annual found throughout North America, usually in sunny sites. It can crowd out garden plants, plus ragweed pollen causes hay fever. Learn to recognize the deeply cut leaves, and pull young plants from moist soil or spray them with an organic herbicide containing acetic acid or clove oil.

Shepherd's Purse Tucson AZ

Shepherd's purse ( Capsella bursa-pastoris ) and several similar wild mustard cousins grow as cool-season annuals throughout North America. Seedlings are hardy to 0 degrees F, and often begin flowering at a young age. Triangular seedpods quickly develop. Left uncontrolled, one plant may shed 40,000 seeds. Young plants are easy to pull from moist soil, and they make good compost fodder.

Slugs and Snails Tucson AZ

These mollusks are found throughout North America, particularly in moist, temperate climates. Snails require calcium for their shells, so are less common in areas where this mineral is lacking.

Smartweed Tucson AZ

Smartweed ( Polygonum pensylvanicum ) and closely related lady's thumb ( P. persicaria ) are a shade gardener's worst nightmare, because they grow best in moist partial shade. Found throughout North America, these native annuals produce thousands of hard-coated seeds. Plants occasionally grow to 4 feet tall, but even when mowed repeatedly smartweed often manages to produce flowers.

Sorrel Tucson AZ

Sorrel ( Rumex acetosella ) is closely related to the salad herb of the same name, but the wild version is often called sheep's sorrel. The young, arrowhead-shaped leaves are edible and have a sharp, sour flavor. A hardy perennial, sorrel is most common in the eastern half of North America. Plants spread by seed, and by producing plantlets on shallow roots.

Squash Vine Borer Tucson AZ

Squash vine borers are pests of crops east of the Rockies. The adult is a moth that lays its eggs on the stems near the base of the plant in late spring to early summer.

Tarnished Plant Bug Tucson AZ

This bug gets its name from its coppery-brown color. It is a major pest, especially for commercial growers. The list of favorite hosts reads like a catalog of major crops: apples and cotton to flowers and vegetables.

Thrips Tucson AZ
