I like the articleGeneralities Forsythia x intermedia
The Forsythia x intermedia is medium in size and 2 m 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. These plants give origin to a brush with a rounded form. The Forsythia x intermedia has a shrub- like development. Fertilization Forsythia x intermedia
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. Exposure Forsythia x intermedia
The the Forsythia x intermedia should be grown outdoors; it can bear very harsh temperatures without any problems, even many degrees below zero. the Forsythia x intermedia should be grown in a bright place, with direct sunlight.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. Watering Forsythia x intermedia
Water rarely, about once every 2-3 weeks with 1-2 buckets of water , keeping the soil dry for a few days before watering again; when wetting we suggest avoiding surpluses, however to wet the soil deep down. 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. Treatments Forsythia x intermedia
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. Soil Forsythia x intermedia
For these shrubs it’s necessary to choose a rich and deep substratum , which presents an excellent drainage.
