Lighting conditions

Rhododendron flourish in the deep tree shade and is too loose in the growth often low. Everyone also fast if rhododendron on the sufficiently damp ground full sunny stand stands, a stand is that way in air-drier areas in the shade area of buildings, as a rule better still in the light shade great recommend copses. Primarily if the shade against too hot sun ray treatment in the middays (11 till 3 p.m.) is caused with that.

Ground preparation and plantationThe composition of the floor must be for relaxed, humushaltig and water permeable for rhododendron. This one the acid value lies for example between the pH results 5.5. and 6.5 here, suffices bringing in bright loose not too fine peat in addition so into however only durchfeuchtetem condition may be used for this planting preparation well.The best planting time for rhododendron hands May from beginning of September by middle of November and from beginning of March by middle. Rhododendron may be started only 3 cm more deeply more deeply than they have been in the Anzucht not with her bale. It is also important that ñ wetness below the bale damming one by badly water permeable layers of soil is avoided ñ like already mentioned already (gravel drainage!) As a rule, 3 must broader and twice be dug as deeply as does without the root bales the planting pit till 4 times. 1:1 should proportionally be used mixed with duchfeuchtetem, asbright as possible peat the ground end piston stroke at the plantation. Is of fertilizer boni at the plantation absolutely warn.

Acting as a fertilizer measures

Healthy, dark green belaubte rhododendron, our urgent piece of advice which richly flourishes every year, require every year a sufficient diet, muss.Rhododendron and azaleas need to be this one adapted to the plant sizes respectively from April till Octobers a food supply which is slow fluent and measured out evenly, this ones planting hole is executed, a first Düngung (40-60 g/sqm) recommends to himself 12+12+17 (+2) with proven and approved full or long time fertilizers such as Nitrophoska special in following March/April 15+5 ++ 20 (+2) for Floranid, Nitrophoska, perfect, permanent for 15+9+15 for (+2), for Osmocote rhododendron fertilizer for 10-15-13 or comparable fertilizers under free gift of few horn shaving. Under such weather conditions below the outer third of the Blattbereiches (approximately 90 g/sqm) evenly thinly spread the fertilizer for acting as a fertilizer recommendation for older bigger about 70-120 cm high plants already grown well: and easy into the ground one scrapers in March/April. We in addition recommend the free gift of 50 -70 g/sqm of horn shaving which promotes a deep green Belaubung and rich flower bud formation in special way. Therefore more than 1.2 m to 2 m have a higher sewing substance need 90 g/sqm horn shaving and get approx. 30% more full fertilizers, about 120 g/sqm Nitrophoska (see above) and approximately older rhododendron. Kleinlaubige rhododendron, dwarf rhododendron and Japanese azaleas need only the half of the given crowds for her diet.

Notice: Rhododendron fed only correctly developing a beautiful deep green, thick Belaubung.Nachdüngung particularly after rainy time periods: (end of June/beginning of July recommend himself a Nachdüngung in such cases for g/sqm or ñ depending on size of the plant - a little less) for Nitrophoska special under free gift of horn shaving for 30 -50. Also purely organic fertilizers such as Oscorna are suitable for this Düngungen.

Is for care work and moving cut advisable just after the heyday (with the new end drive)!break the punctual distance of the abwelkenden inflorescences off by careful. Older big plants stand without far unite form or also moving cut which should be carried out in the beginning of March best in the early spring. It has to be made sure that back cut plants can develop the necessary strength for regenerating only by Düngung. They may under no circumstances become after the moving cut in the same or following year umgepflanzt.

Nitrogen defect

Shows nitrogen defect, pale yellow coloring of the leaves, even distributed over the whole Blattflächen. To the remedy s is (an immediate Düngung with the recommended full fertilizers and horn shaving. Acting as a fertilizer recommendation) required.

Chlorosen

Also arise under circumstances by the fact that the planting pit was made too smally at the plantation. Remain yolk coloring of the sheets of not even, veins green. The means "Celaflor ground therapy Rhodovital" are suitable for the remedy. For young plants the iron fertilizers "Fetrilon" or "Sequestren" can be used to the emergency aid in the pouring method.

Alga formation on the leavesoberflächen

Causes deep shade circumstances permitting an unwanted alga formation on the Belaubung within damp years the very well plant wholesome, not bee dangerous "splashing means Weißöl" or this suitable end drive-splashing means "Para summer" whose films of oil suffocate the alga coating for the remedying of this unsightly sight. Use though only on mature fallen leafs within the months February till April.

Knospensterben

cause by the rhododendron cicadaPhenotype:  Brown flower buds which are inferred and numb, dried up and not falling, covered with a dark-haired mushroom lawn. This is a mushroom infection also appearing with us in Europe for some years, Septembers of the rhododendron cicada dating from America transfer in the time from middle of July by end. The harming picture is recognizable as a result of the infection only hereinafter mostly year (March/April.) To the damage demarcation you should break off and dispose into buds which are next to the February/March recognized, affected and died.Cicadas hatched out freshly to the further fighting, this one as of middle of June like big gnats in the area the rhododendron around shear confused, have to these insects with an authorized remedy to the insect fighting in the spraying method which should safety more halfly circumstances permitting be repeated again after 10 days be destroyed. The following means are suitable for this measure: The synthetic Pyrethroid "Decis" or preparations like "Roxion" or "Perfekthion". However, a success is ensured only then, if the Blattunterseiten also become benetzt completely with the respective means. Remark:  As a wetting remedy against this the bonus of 5 -8 drops of a washing-up liquid is (e.g. especially a smooth, for together pearls and for dripping of the splashing means for "Pril" for o.a. on 10 liters of water always required (water diversion) for the leaves for many for rhododendron "wachsige" surface has
