You may have containers of new potatoes growing in your greenhouse ready for harvesting at Christmas but it’s time to make certain that slugs are not already gorging themselves on your upcoming bounty.

Gardeners bring their more tender pots and containers into the greenhouse as the mercury drops but, along with the plants, there may well be slugs and/or vine weevils lurking in the soil.  As they warm up they can exit their homes in search for other tasty meals.  The Christmas potatoes offer a delicious opportunity.

According to BASF, nematodes may be able to save our roasties!

Nematodes are microscopic worm-like creatures that occur naturally in garden soil.  Each different nematode species has its own unique prey and BASF breeds different varieties to target different garden pests. Trillions of Nemasys nematodes are bred here in the UK at BASF’s unique production facility in Littlehampton.

Set this microscopic army of nematodes loose on your spuds before bringing the pots and containers into the greenhouse. 

Nemaslug slug killer and also Nemasys Vine Weevil Killer can be mixed together.   The  products arrive in the form of a paste and are mixed with water and sprayed onto the pots via a watering can with a coarse rose.  Two treatments should deal with the problem.

Nemaslug and Nemasys products can be purchased from
