Also, use 1⁄2 litre molasses to 2 litres water; spread over 11⁄2 square metres of affected area.

Weeds in general – will kill all plants
1 cup salt dissolved in 1 litre vinegar. Brush all weeds you wish to kill.

To attract Lacewings which eat aphids etc.

It is good practice with any homemade remedy to first spray a test patch on the target crop and wait 24 hours before checking the sprayed foliage for damage, before proceeding.
