To prevent damage caused by the cold temperatures, during the months with definately harsh minimum temperatures, we can protect the shrubs by covering the soil around the stem with straw or dry leaves. We suggest to position the The African senna in a sunny spot at least a few hours a day.These plants don't like excessively harsh temperatures, with night-time minimum temperatures below 0°C. during the spring in general they are grown in a covered place, moving them outdoors, or uncovering them, when there isn't any danger of sudden temperature drops.
Fertilize African senna
Shrubs develop new shoots and prepare their flowers during the spring period, therefore we must remember, by the end of the winter, to give it a good dose of humus or mature manure, or granular slow release fertilizer, to be added to the soil at the foot of the plant. During the spring we can choose a fertilizer rich in nitrogen and potassium, to mix with the irrigating water, every 20-25 days.
Cultivation African senna
These plants give origin to a brush with a rounded form. The African senna has a shrub- like development. The African senna is medium in size and 90 cm in height; in the spring it assumes a yellow colouring. These plants aren't evergreens, which means they lose their leaves some months during the year.
Water African senna
Water sporadically, with 1-2 buckets of water , leaving the soil dry for a few days before watering again; when watering we suggest avoiding excesses, but to wet the substratum well. Let's act every 2-3 weeks . If we want to grow these plants in a vase, we should water them a bit more often, compared to plants cultivated in the ground; Every 2-3 years we should renew the substratum in the vase, or enrich with organic amender.
Pests African senna
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
Mold African senna
For these shrubs it’s necessary to choose a rich and deep substratum , which presents an excellent drainage.
