Duranta plants need full sun to get the energy they need to make blooms and berries. Plants growing in too much shade often get lanky and sparse.
When growing duranta plants as annuals, provide rich, loamy soil to help the plants reach their potential in one growing season. In their growing zones, duranta plants can tolerate lean soil, as long as they have good drainage.
Duranta plants require a moderate amount of water. Plants growing outdoors need the equivalent of about an inch of rain per week. When growing in containers, water your duranta when the top of the soil feels dry.
Temperature and Humidity
The duranta likes it hot, and even triple-digit temperatures won’t slow it down. If you are growing the plant in a container, bring it indoors when temperatures dip below 40 degrees Fahrenheit. Furthermore, duranta plants do well in both dry and humid conditions. They also tolerate the salty air of beach climates.
Duranta plants are not heavy feeders and can get by without any supplemental fertilizer in rich soil. In lean or rocky soils, you can use an all-purpose general fertilizer once a month during the growing season.
