What Is Wrong With My Gold Flower?

Is there a white mycelial mat on the lower trunk or in the soil around your plant?

Are there any rust-colored spots on foliage?

Are the leaves covered in coarse stippling and may appear silvery?

Are the surfaces of the leaves scraped or with chewed holes; leaves are discolored and may drop prematurely?

Dematophora root rot, or white root rot, is not as common as other root rot fungal diseases are, but when it occurs, it can quickly kill plants. Symptoms may be exhibited throughout the entire plant or in just a portion of the canopy. Branches killed as a result of Dematophora often retain dry foliage. A white mycelial mat may be visible on the lower trunk or in soil over infected roots. Minimize Dematophora -caused disease by preparing the site well before planting, using quality nursery stock, and providing appropriate cultural care, especially proper irrigation.

Rust-colored spots on foliage indicate a fungal disease - Rust. Provide good air circulation around plants by thining them. Avoid making leaves wet when watering. All infected leaves should be removed. Spray leaves with sulfur early in the season to prevent rust or to treat mild infections.

These symptoms may indicate thrips. Thrips are tiny, yellow to black flying insects. Severely infected plant parts should be removed and destroyed. Control thrips by introducing lady beetles or lacewings, their natural predators. Insecticidal soap helps in severe infestations.

Klamathweed beetle is a leaf beetle that attacks gold flower foliage. Beetles scrape the surface or chew holes in leaves. Leaves discolor and may drop prematurely. High populations cover leaves with dark droppings and can skeletonize or defoliate entire plants. Provide proper cultural care to keep plants vigorous. Remove dead or dying branches. Consider replacing problem trees with resistant species. Bacillus thuringiensis ssp. galleriae selectively kills leaf beetle adults and larvae that consume sprayed foliage.

Mineral deficiencies can cause tip chlorosis or necrosis or cause foliage to discolor, fade, distort, or become spotted, sometimes in a characteristic pattern that can be recognized to identify the cause. When nutrient deficiencies occur, nitrogen and iron are the most commonly seen deficiencies. Apply only the mineral found to be deficient. Excess nutrients, on the other hand, causes symptoms like leaf tip dieback, marginal leaf chlorosis, necrosis (or burn), branch dieback, and pest problems. In this case, you should provide good drainage, and use good practices during fertilization and irrigation.
