Lifespan, Perennial or Annuals

How long is the lifespan? Although some sources claim that the plant is an annual, most gardeners report that it is a perennial in warm climates. The plant typically blooms in late spring or early summer and continues to bloom sporadically through fall.

Ideal Temperature

What is the ideal temperature? Because it is a thermophilic plant, the content temperature in summer should be around 77-82.4 degrees Fahrenheit. In winter, the temperature should be lower, around 59-62.6 degrees Fahrenheit, but not below 44.6-51.8 degrees Fahrenheit.


What about the humidity? The plant Streptosolen easily adapts to conditions of low humidity (about 35%). However, it is useful for him to regularly spray, preferably in summer in extreme heat or in winter, if the plant is contained in an intensively heated room.

Light Requirement

What amount of light this plant needed? Because Streptosolen plants need very bright light for normal growth and flowering, the vase should be placed on a windowsill on the south, south-west, or west side of the house. In winter, when Streptosolen plants are kept in relatively cool conditions, the lighting should be moderate.

Soil Composition

What is good soil for Streptosolen? Although this plant is native to South America, it will grow in any light permeable, fertile substrate. A mix of leaf land, humus, peat, sand, and perlite will do, or you can use any loose store substrate with a pH of 5.5 to 6.5. Good drainage is required.

Watering Time

How much I must water Streptosolen? If the soil dries out to a depth of 3 cm, it is necessary to water the plant abundantly. This should be done 3 times a week. In hot weather conditions, the plant needs to be watered more often. If the soil dries out completely, the leaves of the plant will begin to hang, and the plant will clear the lower leaves. The trunk of the plant will be laid bare. In winter, the intensity of irrigation should be reduced.

Fertilizing and Nutritient

About fertilizer. If you want your Streptosolen to really take off and have an abundant growth, you should fertilize it during the growing season with a complex fertilizer that has an elevated phosphorus content. This should be done approximately every 3 weeks, with young plants particularly in need of additional fertilizing. Fertilizers with a high nitrogen content will lead to an abundant growth of the vegetative mass, but flowering may not occur or be weak. At the end of the growth period, the top dressing should be gradually reduced.


How to reproduce Streptosolen? So, the plant is propagated by cuttings, which are cut in spring and rooted in a mixture of peat and sand, covered with polyethylene. Also, the plant can be propagated by seeds, which are sown in a mixture of peat and sand to the depth of about 3-4 mm. The seedlings should be placed in a bright place, but not under direct sunlight. It is necessary to constantly moisten the substrate. Germination lasts approximately 3-4 weeks. After 1-2 months the seedlings can be placed closer to the light, but still not under direct rays and only on the 4th month they are put on a bright sun.


Why Streptosolen won't bloom? When it begins to bloom in the spring and summer it blossoms abundantly. The flowers are yellow at first and then they turn bright orange. The bright color of flowers are called “marmalade bush”.

Sometimes it is possible to carry out transshipment in the summer, if the roots have appeared through the drainage hole. The plant takes a regular pruning by one third every spring, it will promote better branching. You can also trim after flowering, new flowers appear on the shoots of the previous year. During growth, it is necessary to pinch the paws for support. You can use a ladder for the plant or shoot the shoots on the supports on the wall. You can use wire supports in the form of a circle, braiding around them shoots. Sometimes a plant is formed in the form of a binder.
