Did you planted your Basket-Of-Gold in full sun?
Did you planted your Basket-Of-Gold in well-drained soil?
Do you live in a region with a hot and humid climate?

Do you keep your Basket-Of-Gold free of pests and diseases?
Basket-Of-Gold plants flower best when grown in full sun. However, in hot climates, the plant likely will enjoy some afternoon shade to prevent the foliage from depreciating.
Basket-Of-Gold likes average to sandy soil with excellent drainage. It can tolerate shallow and rocky soil. But heavy clay soil or other soil types that remain moist and drain poorly can cause root rot and kill the plant.
Basket-Of-Gold has some cold tolerance and grows well from USDA hardiness zones 3 to 7. However, it struggles in hot and humid weather. Consequently, in the South many gardeners treat it as an annual, enjoying its spring flowers before the foliage depreciates in the summer heat and humidity.
This plant doesn't require much water and thrives in dry soil. Overwatering can be deadly to Basket-Of-Gold. Because it has good drought tolerance, you'll likely only have to water if you have an extended period without rainfall and your plant begins to wilt and lose its leaves. If you are growing your Basket-Of-Gold in a container, be especially careful not to overwater. Wait for the soil to dry out between waterings, and verify that the container has good drainage.
Fertilizer typically isn't necessary for Basket-Of-Gold unless you have very lean soil. Too much fertilizer can result in poor flowering and a scraggly growth habit. If you wish, you can fertilize every other year in the fall with a low-dose organic fertilizer or compost.
Good job! You are taking good care of your Basket-Of-Gold.
Basket-Of-Gold can be susceptible to quite a few pests and diseases. Aphids, cyclamen mites, and leafminers are common pests. Use insecticidal soap or neem oil if you notice these small pests. Be on alert for botrytis blight, downy mildew, root rots, and clubroot which are all common diseases of Basket-Of-Gold plants.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
