Neudorff Nematodes Vine Weevil killer

5 million nematodes for Vine Weevil-free plants. 

WINNER OF THE 2018 GARDEN INDUSTRY MANUFACTURERS ASSOCIATION AWARDS. The judges said.....'a product that says great things about ecological gardening and really opens up the market for consumers'.

Naturally occurring Heterorhabditis bacteriophora nematodes will kill vine weevil grubs in the soil, preventing them from killing the roots of your precious plants. All without the use of pesticides! Each pack will treat 12m2 or up to 210 pots, so this is a highly economic method of controlling the devastating vine weevil grubs. Pet friendly in or out of the packaging! 

Nematodes are microscopic roundworms that can be found in almost every ecosystem. Some species are predatory and can be used in horticulture to control soil-borne pests. They enter vine weevil larvae and inject it with bacteria, causing its death. The nematodes will then eat the dead body, multiplying within it, and immediately search out new vine weevil larvae to act as their host again. Once the host is killed, the life cycle of the nematodes will also stop, leaving no trace in the compost. 

Nematodes thrive in soil at temperatures between 10-30C, and can start working immediately, though it may take time for the full results to be seen. Applications are best from April to September. Unlike most nematodes that need refrigeration for storage, Neudorff nematodes are placed in a state of 'cryptobiosis' which prevents them from moving or using oxygen, and they can remain alive in this state for up to 6 months. 

If you see the tell-tale signs of vine-weevil notching on the edge of leaves, apply nematodes to very moist soil around the rootball, in the morning or dusk when temperatures are cooler. Evening applications are recommended as UV light kills nematodes. Applications on rainy, overcast days encourages optimal penetration into the soil. 

Simply drop the 'tea-bag' sachet into tepid water and stir for 1-3 minutes until the water becomes cloudy, and the nematodes have diffused out. Do not over-shake as this will cause the sachet to break, and the carrier material can block the sprayer or watering can rose. Drench the roots of your plants, so that the nematodes can seek out and kill any weevils. 

Store in cool conditions. Child and pet safe. Always use in accordance with label instructions. Use before expiry date.

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.
