At­tack pests on vul­ner­a­ble plants

Use ne­ma­todes to deal with those pesky, un­wanted vis­i­tors

Garden News (UK) - - What To Do -

Au­tumn’s a great time to use bi­o­log­i­cal pest con­trol, as it’s when a new gen­er­a­tion of pesky grubs is pro­duced, ready to de­scend on our gar­dens and turn into adults next year. Ne­ma­todes, which are more and more widely avail­able in gar­den cen­tres th­ese days as we try to use fewer chem­i­cals when gar­den­ing, are mi­cro­scopic or­gan­isms that feed on pests and dis­in­te­grate them from the in­side out. Not a pleas­ant thought!

But their work is un­de­tectable to the naked eye – as are they, com­ing in var­i­ous forms in a paste or pow­der, each type la­belled for you to at­tack a dif­fer­ent pest that may be both­er­ing you.

All you have to do is add some of the pow­dered pack of ne­ma­todes to a large wa­ter­ing can, as per the packet in­struc­tions, and wa­ter onto the af­fected area straight away. Wa­ter on again with fresh wa­ter to wash it all in, and then reap­ply a few more times over the next few days. A good tip is to also use ne­ma­todes in low sun­light, as they’re sen­si­tive to it.

Sadly, for plants that are al­ready too far gone, such as con­tainer plants that have been rav­aged at the roots by vine wee­vil so there’s none left, you’ll have to throw them away. But for the healthy plants that are left, in about a week or two you should start to no­tice some nice, pest-free results.

Sim­ply add the pow­der to your wa­ter­ing can and ap­ply to the af­fected area, right
