Ivy is one of the most common plants among indoor flower lovers. It is so rich in various forms and varieties that it can satisfy the taste of even the very picky grower. Since ivy multiplies easily and is quite common, if desired, it would be possible to collect a whole collection of ivy up to 30 or more different species of this wonderful plant, which, by the way, is sometimes called a loach by the people, probably because of its twigs and clinging to the support. Such specimens can grow, which with their whips cover not only the wall, but also the ceiling of the room. Ivy looks for support and attaches to it with aerial roots. Therefore, he needs support: either a vertical one in the form of a stick or a tube with moss or stretched cords. Flowers in ivy are small in heads, appear in older specimens on branches with whole leaves.
For cultivation in culture, small and variegated forms are primarily suitable, differing in color, shape and size of leaves. The most common type is the common ivy Hedera helix, this species has a lot of varieties:
- varieties with almost oval and rounded leaves (Hedera helix Harald, Hedera helix scutifolia)
- varieties with star leaves (Hedera helix sagittaefolia)
- varieties with corrugated edges (Hedera helix cristata, Hedera helix Ivalace)
- varieties with smooth edges, with a pure green color (Hedera helix Annette, Hedera helix Green Ripple)
- varieties with almost yellow leaves (Hedera helix Eva, Hedera helix Mona Lisa)
- varieties with spotted leaves (Hedera helix Jubilee, Hedera helix Glacier, Hedera helix Glorie de Marengo)
Ivy (Hedera) is a wonderful and unpretentious plant, very tenacious at home: it grows in shaded places, tolerates warm wintering well, is perfect for both the bedroom and the kitchen. This does not mean that you do not need to look after him - the density of the crown and the abundance of shoots depend on the conditions of care. The more comfortable a plant is in your home, the more luxuriant it looks - it can grow into a real green carpet. Periodically, once every 3-5 years, the heder may require rejuvenation of the bush - cutting off all the shoots, which, after re-rooting, are planted in one pot. In spring the ends of the shoots should be trimmed to stimulate better branching.
Common ivy grows well in a wide temperature range, optimal for it is 20-26 ° C day and night no more than 16 ° C - this is the temperature at which hedera feels most comfortable. But at temperatures above 30 ° C, it is desirable that there is an air flow, i.e. the room or kitchen is ventilated. At temperatures below 15 ° C - very careful watering, since the main problem of ivy is the bay, and it happens automatically if the plants remain watered on a cold night.
In winter, it is desirable to grow ivy in cooler conditions, at 15-16 ° C, at least 12 ° C. But if this is not possible, the plant will not take offense at you, especially if you protect it from the hot air of the batteries and there will be enough light from the window or from the lamps.
Ivy loves bright, diffused light in spring and summer (east and north), and in autumn and winter in central Russia, he is not afraid of the southern window with direct sunlight - the sun is too low and the days are mostly cloudy. It is poorly tolerated not so much by the direct sun as by the heat, the greenhouse greenhouse conditions oppress it. Green ivy varieties can be classified as shade-tolerant, but still, do not put them in a dark corner! Variegated ivies are more photophilous, in a shaded place they can lose color.
Watering and humidity
Ivy can be classified as a very drought-resistant plant, it does not require watering like, for example, monstera or philodendron, arrowroot or ferns, but rather like succulents - such as jerky, Kalanchoe or forest cacti - Schlumberger. This means that it should be watered more moderately than abundantly - after the top of the soil is dry to a depth of about 5-7 cm (for an average pot).
The most dangerous time for a plant is in spring and autumn, when the heating has already been turned off or has not yet been turned on. During these periods, the air humidity is very high and the soil dries for a long time. So that leaving is not harmful, it is important not to pour ivy, periodically loosen the soil in the pot, do not water it overnight, especially if the pots are on the balcony.
In winter, watering depends on the temperature in the room. If in an ordinary heated apartment, then water as in summer. If it is on a warmed balcony or veranda, watering is moderate, the earth should dry out completely.
Important: ivy tolerates overdrying more easily than waterlogging, especially variegated varieties! If you notice that the leaves and shoots have become kind of lethargic, some leaves do not turn yellow and wilted without drying out - these are symptoms of the bay. Take the plant out of the pot and dry it immediately. If the plant is heavily flooded, when the leaves turn black, they hang like rags, even cuttings from such shoots usually do not take root - they die.
Ivy grows well at a humidity of at least 35-40%. That is, it must be sprayed in winter in frosty weather, when even the curtains at home are electrified or in dry hot weather in summer. At any other time, spraying is not necessary, but the plants need basic hygiene - a lot of dust settles on the leaves, it would be nice if you rinse them once a week or two under a warm shower.
Ivy is transplanted annually if it is less than three years old, and after a year or two old plants, but the top layer of soil they need to be replaced every year - to remove salted useless soil and fill up with fresh soil. The soil is made up of a mixture of 1 part of sod land, 1 part of humus, 1 part of leafy land and 1 part of sand. You can use a store-bought primer for flowers, universal, proven manufacturers, for example, Terra Vita.
What must be done is to make large holes at the bottom of the pot to drain the water. The more, the better, like in pots with store plants. To prevent the earth from spilling out, place a circle of mosquito net on the bottom. As a drainage, use 1.5-2 cm pieces of foam.
How and when to feed ivy
Top dressing is necessary only during active growth, from March to August, every 2 weeks, but not earlier than 1.5 months after transplantation. Heder is fed with a complex fertilizer for decorative deciduous plants. You can use fertilizers "4 barrels", "Pocon", "Agricola", "Bona Forte" and others, which indicate that they are intended for deciduous plants (including palms, ficuses), closer in composition to the fertilizer for arrowroot, but they are quite rare on the market.
Ivy is propagated by cuttings, and often the plants already have aerial roots if they have grown in the last 2-3 months in high humidity. But even if there are no aerial roots, the cuttings will still root in water or wet vermiculite. To prevent the water in the jar with cuttings from spoiling, change it every day to fresh, preferably boiled.
- If you want to root in vermiculite, for this take 1 part of vermiculite and universal peat soil, pour into a small pot, moisten. Then place the pot of soil in the microwave and heat for about 2-3 minutes.
- Let the ground cool and stick in the cuttings. Then place the jar and cuttings in a plastic bag and tie. Open to ventilate once a day.
- When the roots grow back, they will be visible through the glass of the jar, untie the bag, but do not remove, let the cuttings gradually get used to the lower humidity. After the cuttings begin to grow shoots, 3-4 new leaves will grow, they can be transplanted into a larger pot, into the ground, as described above.
