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 Broom in a sunny spot at least a few hours a day.We advise cultivating the The Broom outdoors, since it doesn't fear cold temperatures.
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.
These plants give origin to a brush with a rounded form. The Broom is a plant for a rock garden. The Broom is large in size and 60 cm in height; in the summer it assumes a yellow colouring. These plants aren't evergreens, which means they lose their leaves some months during the year.
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.
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.
For these shrubs it’s necessary to choose a rich and deep substratum , which presents an excellent drainage.
