Grevillea Banks

Protein family. Homeland - Australia, New Zealand, Malaysian islands. There are about 260 species in nature.

  • Grevillea Banks Grevillea banksii is a tree-like shrub several meters high. Young shoots are covered with fine dense pubescence. Leaves are twice pinnately dissected, about 20cm long. Each segment is narrow-lanceolate, green above, covered below with fine reddish pubescence. Bright red flowers are collected in racemose inflorescences. Pedicels and perianths are also covered with fine, dense and downy hairs. The ovary is covered with pubescence.
  • Grevillea is a powerful Grevillea robusta - a tree that grows in natural conditions up to 20m in height. Leaves are double - or thrice pinnately dissected, about 25 cm long. Each segment is narrow lanceolate, often with a jagged edge. The leaf is green above, covered with fine reddish pubescence below. The orange or reddish-brown flowers are clustered in racemose inflorescences. Flower ovary without pubescence.

In all fairness, it should be noted that Grevillea is not the best plant for home growing. First, it is a plant that requires cool wintering and moist air. If these conditions are not provided, the leaves turn yellow in the plant, it is quickly attacked by pests.

Secondly, due to the impossibility of providing ideal conditions, the plant practically does not bloom in indoor conditions. But it grows rather quickly and requires periodic pruning, otherwise the plant will reach the ceiling in a few years. But for spacious, bright and cool halls, winter gardens and greenhouses, this is a very good plant.

Grevillea - care and cultivation

Temperature: Grevillea is a greenhouse plant, prefers moderate temperatures, optimally in summer about 20-22 ° C, does not like heat in a stuffy, unventilated room (on the sunny side of the house). In winter, about 12 ° C, minimum 8 ° C. In an ordinary apartment, she will suffer during the heating season.

Lighting: bright diffused light, obligatory shading from direct sunlight in summer. Grows well near the east or northwest window.

Watering: Abundant during the growing season - the soil should be slightly moist all the time, but dry out in the upper part of the pot before the next watering. In winter, watering is rare, its frequency depends on the temperature; in cool conditions, it is watered after thorough drying of the earth. Grevillea does not tolerate waterlogging of the substrate.

Top dressing: from March to August with fertilizer for indoor plants every two weeks.

Air humidity: He likes very humid air, so the leaves are regularly sprayed, the plant is placed on a wide pan with wet gravel.

Transfer: annually in the spring. The pot should not be too deep. The soil is only slightly acidic reaction. The soil is a mixture of 1 part leafy soil, 2 parts coniferous, 1 part peat and 1/2 part sand. Good drainage is a must.

Reproduction

Grevillea propagates by semi-lignified cuttings and seeds. Cuttings for rooting are cut in August. It is necessary to cut off semi-lignified shoots with a heel. Sprinkle the end of the cutting with phytohormone powder and place it together with the pot under the bag. For rooting, a temperature of 18-20 ° C is needed.

Grevillea from seed

For reproduction of Grevillea, only fresh seeds are taken, as they quickly lose their germination. Before sowing, soak the seeds in a solution of "zircon", "epin", but better than the drug "narcissus", according to the instructions. The seeds should be sown in a light nutritious soil mixture. To do this, mix 1 part of leaf humus, 1 part of universal peat soil and 1 part of vermiculite. Sprinkle the seeds with earth in a layer of about 7-10 mm, water and cover with glass or a bag. Put in a warm place at a temperature of 22-25 ° C.

Two to three times a day, it is necessary to ventilate the crops, shaking off the condensate. Maintain the soil strictly in a moderately moist state, no dampness or overdrying! To prevent the seeds from rotting, water the crops once with a solution of phytosporin or phytolavin.

Germination begins in 2 weeks. Seedlings are rarely amicable, and germination is usually 50-70%. When sprouts appear, you need to put a bowl with crops in a very bright place. Grevillea grows rather slowly, loves light and good humidity.

You can transplant grevillea seedlings in separate pots when a pair of real leaves open. Take small pots, about 8 cm in diameter, the soil for planting is the same - a light, slightly acidic reaction. In hot summer weather, arrange the pots on a wide tray with moist sphagnum moss. The first year, plants can winter in normal indoor conditions (warm) on a sunny windowsill and humidified during the heating season. In the second year, a cool overwintering is needed.
