Alles um Hosta

<spanstyle="font-size: 12pt;"="">What do you need to know about hostas(funkias)?

<spanstyle="font-family: arial;="" font-size:="" 12pt;="" font-weight:="" bold;"="">

They are decorative perennials consisting mostly of leaves. They come from Far East ( China, Japan). In autumn their leaves turn yellow and wither.


This specie has a huge number of varieties. Over 5000 have been registered.


Among them you can find miniatures of 10cm in height as well as giants of 140cm in height and over 200cm in diameter.


They are incredibly vivacious. To live 100 years in one place is no problem for them. However this has its price: long maturation time. Most varieties' young hostas do not resemble at all a matured plant, their leaves have different shape, color and texture. It is generally presumed that the hosta matures only after 3 to 4 years of growth in one place and after 6 to 7 years it reaches its final size.


Growing:

Growing is very simple. They like drained, slightly acidic (6 pH) and slightly moist soil, however they actually grow on almost every soil and endure drier periods well.


If we want to have lush and beautiful plants we need to remember about watering on especially hot days.


Fertilize in early spring using fertilizer with more nitrogen NPK 20-10-10.


Later use balanced fertilizers NPK 20-20-20 or 10-10-10. Using fertilizers with more nitrogen causes brightening of green colors and greening of the blue ones. It's convenient to use balanced fertilizers of Osmocote type, which are longer effective.


Hostas like bedding. Bark, cones and broken twigs are good materials for that. It allows the ground to stay moist for longer.


Position


Hostas generally are shade plants. Only a small number of them can endure more sun. You can be tempted make some generalizations, which however, are not rules.


Blue, gray, blue-green and dark-green hostas gain best colors in deeper half-shadow and shadow.

Yellow, golden-yellow and yellow hostas with colorful margins gain best colors in bright half-shadow with before-noon sun. There are, however, Color Glory type varieties which cannot bear direct sun which burns their sensitive leaves.


Completely green hostas can endure the most sun.


Problems:


Snails are a big problem when growing these plants. There are varieties described as snail-resistant, but leaves of many varieties are their delicacy, so it's good to prevent this problem.


They are relatively resistant to illness. With prolonged increased humidity fungal infections can occur. They are pretty easy to fight with fungicides available at garden shops.


Another serious problem is hosta X virus "HVX", which is described at a different site.
