Cultivation

Growing Tips:
Zinnias thrive in hot weather and prefer full sun. Plant in good soil and fertilize regularly. Zinnias require a regular amount of water. Shear spent blooms to encourage rebloom.

 

Pest Management


Your zinnias want nothing to do with these pests!
  • Aphids
    Aphids are small, soft-bodied insects with long, slender mouth parts that they use to pierce stems, leaves, and other tender plant parts and suck out plant fluids. Almost every plant has one or more aphid species that occasionally feeds on it. Many aphid species are difficult to distinguish; however, identification to species is not necessary to control them in most situations.

  • Broad mites, Cyclamen mites
    Cyclamen and broad mites are about one-fourth the size of spider mites and can't be seen without a microscope or a 20X magnifier. Adult cyclamen mites can be translucent white, pinkish orange, or pale yellow. Broad mites are often translucent, yellowish, or greenish, and female broad mites have a white stripe down the center of their back. Broad mites have a tapered body that is widest between their second pair of legs and more narrow toward the rear. Cyclamen mites have sides that are more nearly parallel, not sharply tapered.

  • Earwigs
    Earwigs are among the most readily recognized insect pests in home gardens. Although they can devastate seedling vegetables or annual flowers and often seriously damage maturing soft fruit or corn silks, they also have a beneficial role in the landscape and have been shown to be important predators of aphids. Although several species occur, the most common in California gardens is the European earwig, Forficula auricularia, which was accidentally introduced into North America from Europe in the early 1900s. The striped earwig, Labidura riparia, occurs in southern California and can annoy residents when it is attracted to lights. It has a very disagreeable odor when crushed. However, the striped earwig does not damage plants.

  • Leafminers
    Leafminers attack many different flower hosts, including aster, begonia, dahlia, impatiens, lily, marigold, petunia, and verbena. Adult Liriomyza are small, active, black and yellow flies. The most important species are the serpentine leafminer (Liriomyza trifolii) and the pea leafminer (L. huidobrensisa). Larvae are yellow cylindrical maggots.

  • Spider mites
    Mites are common pests in landscapes and gardens and can be found feeding on many fruit trees, vines, berries, vegetables, and ornamental plants. Although related to insects, mites are not insects but members of the arachnid class along with spiders and ticks. The spider mites, also called webspinning mites, are the most common mite pests and among the most ubiquitous of all pests in the garden and farm.

  • Thrips
    Thrips, order Thysanoptera, are tiny, slender insects with fringed wings. They feed by puncturing their host and sucking out the cell contents. Certain thrips species are beneficial predators that feed only on mites and other insects. Beneficial species include black hunter thrips and the sixspotted thrips. Pest species (often in the family Thripidae) are plant feeders that scar leaf, flower, or fruit surfaces or distort plant parts. Other species of thrips feed on fungal spores and pollen and are innocuous.

  • True bugs
    True bugs usually have thickened forewings with membranous tips. When they rest, the dissimilar parts of their folded wings overlap. Most true bugs can be recognized by the characteristic triangle or X-shape on the back formed by their folded wings. True bugs have sucking mouthparts, which on plant-feeding species point downward, perpendicular to the plane of the insect's body. Common true bugs are lace bugs (tingids), boxelder bugs, ash plant bugs, lygus bugs, stink bugs, and chinch and false chinch bugs.

  • Whiteflies
    Whiteflies are tiny, sap-sucking insects that are frequently abundant in vegetable and ornamental plantings. They excrete sticky honeydew and cause yellowing or death of leaves. Outbreaks often occur when the natural biological control is disrupted. Management is difficult.
