Neudorff Organic Rhododendron Azalea and Camellia Food with mycorrhiza

An exceptional NEW product!  Up until now, there has not been a mycorrhizal fungi that has worked with Rhododendrons.  This new organic fertilizer from Germany contains a specially developed mycorrhizal fungi which aids the rooting of Rhododendrons, Azaleas and Camellias.  We were aware that this research was taking place more than 10 years ago, and the development programme has been long and extensive, but now the results are most impressive.  We have seen comparison pictures of rootballs planted with and without this fertilizer, and the differences are huge!  Neudorff are even claiming root systems up to 150 times larger!  We are certainly trialling it our our nursery this season. 

The beneficial mycorriza fungi are incorporated into an organic granular fertilizer (7-3-5) which lasts 3-4 months.  Ideal for mixing into the planting hole, and working into the compost during March-April, and again after flowering in June-July. 

Contains natural organic raw materials, including micro-organisms Bacillus amyloliquefaciens, B. licheniformis, B. megaterium, B. pumilus, Hymenoscyphus ericae.

The Basics

Ideal soil

Acidic soil, good organic content, pH 4.5-6.0. Inkarho range of rhododendrons will tolerate soils up to pH7.5

Sun or Shade

Light dappled shade is best for most varieties.

Shelter

Refer to hardiness rating. Give young plants protection.

Site Selection

Avoid close to trees, roots, invasive weeds, walls, hot patios, dry banks and waterlogged soils. Do not use weed matting or stone mulch.

Plant spacing

Use the height shown in 10 years as a guide to the distance between each plant. Allow room for plant to fill out. If planting closer for instant impact, be prepared to move plants after a few years.

Compost

• 3 litre pot, dig in 10-20 litres of ericaceous compost.
• 7.5 litre pot, dig in 20-30 litres of ericaceous compost.
• 70-80cm specimen, dig in 60 litres of ericaceous compost.
• 100-120cm specimen, dig in 120 litres of ericaceous compost.

Planting depth

Plant high in the ground, with the top of the rootball visible.

Feeding

Slow-release ericaceous feed recommended in March and straight after flowering.

Mulch

Recommended every few years.

Water

The key ingredient! Keep moist all season, especially the critical time at end of June for flower bud initiation. Tap water is better than no water. Heavy dose at least once per week in dry weather.

Drainage

Ensure good drainage in winter, especially with yellow flowering varieties. Avoid waterlogged sites.

Pruning

Rhododendrons and Camellias: Not normally required. Tidy wayward shoots after flowering.

Evergreen azaleas and Bloombux can be clipped into a low hedge.

Magnolias and Acers: Formative pruning when young to shape into a tree or bush.

Deadheading

Remove old flower-heads, particularly on young or weak plants.
