Hi people!!
Have heard a tip to stop blight on tomatoes in a greenhouse. Plant a Marigold at the base of each tomato plant and you will be blight free. Is this true or an old wives tale??

Hi Phil

Just wrong

French marigolds and tagetes will (it is said) deter whitefly and aphids. Blight is a fungal disease and will be unaffected.

Many thanks.
