Grevillea (Grevillea, fam. Proteinaceae) is a fast-growing shrub or tree with lacy, fern-like leaves. The underside of the leaf seems silky; it is covered with soft hairs. Grevillea flowers are orange, collected in brushes. The homeland of Greville is the islands of New Guinea and Australia. One type of grevillea is grown in the room - a powerful grevillea (Grevillea robusta). If you need an inexpensive indoor plant-tree, then you should choose a grevillea. It is easily propagated by seeds or cuttings and in one year grows up to 30 cm in height, and after 4 - 5 years reaches the ceiling.
Grevillea feels good in a bright and cool room. In summer, it can be taken out to the garden or to the balcony, you just need to shade the plant from direct sunlight. The temperature is required moderate or slightly lower than moderate, in winter at least 5 - 8 ° C. Grevillea well tolerates the dry air of rooms, but from time to time it is useful to spray the leaves.
Grevillea is watered abundantly from spring to autumn, in winter moderately. From April to September, full mineral fertilizer is applied twice a month. In order to stimulate the growth of young shoots, the grevillea needs to be cut off greatly. The plant is transplanted up to three years every spring, subsequently - after 2 years. Use a soil mixture of turf land, peat, humus, leaf soil and sand in a ratio of 1: 1: 1: 1: 1.
Grevillea may be affected by whiteflies. Clusters of small white insects and their larvae can be found on the underside of the leaf. The plant needs to be treated with an actelik and rearranged in a drier and brighter place.
