It is advisable to position this plant in a partially shady place, where it is exposed to direct sunlight only during the coolest hours of the day. Letís remember that bonsai usually are grown in quite contained containers; this is why we suggest moving the vases in a slightly shaded place during the hottest weeks of the summer.The Hawthorn should be grown outdoors; it can bear very harsh temperatures without any problems, even many degrees below zero.
These plants have a sapling deportment, with a short stem with a small roundish crown. The Hawthorn is medium in size and 90 cm in height; in the spring it assumes a greenwhite colouring. These plants aren't evergreens, which means they lose their leaves some months during the year. The Hawthorn has a shrub- like development.
During the spring months letís fertilize our bonsai plants using a specific fertilizer every 20-25 days; during this period of the year the fertilizer must be rich in nitrogen and potassium, to favour the development of new vegetation.
Water rarely, about once every 10-11 days with 2-3 glasses 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. Letís frequently check the soil of our bonsai, to avoid it from remaining dry for long periods of time.
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.
These plants need a substratum with an excellent drainage.
