fourfinches Posted May 11, 2007 Share Posted May 11, 2007 My pepper plants in the greenhouse have white fly . I seem to remember my dad spraying plants with watered down washing up liquid. Has anyone else tried this and if so how much liquid to water? Are there any other suggestions? Thanks Morag Quote Link to comment Share on other sites More sharing options...
Helly Welly Posted May 11, 2007 Share Posted May 11, 2007 I use one of those lance sprayers, filled with water with just a couple of drops of washing up liquid and a drop of vinegar. You will need to spray quite regularly but it does work. Quote Link to comment Share on other sites More sharing options...
Jaime Posted May 11, 2007 Share Posted May 11, 2007 One of those little hand held sprayers that are about 99p from garden centres work well enough. The mixture of vinegar and washing up liquid with water also works on greenfly. Quote Link to comment Share on other sites More sharing options...
ali-s Posted May 12, 2007 Share Posted May 12, 2007 I've got pots of French Marigold outside the greenhouse and a pot of Basil inside. I read somewhere that the Marigolds deter whitefly from entering the greenshouse to feed on the veggies. If that fails whitefly love basil so much they will eat that before touching my Tomatoes.

Karen & co. Posted May 12, 2007 Share Posted May 12, 2007 That's a good idea, feed them a crop you don't need I use companion planting in the veg bed, which seems to work, hope this isn't tempting fate I heard marigolds are good at warding off green fly too karen x Quote Link to comment Share on other sites More sharing options...
