indoor plants have recently become plagued with aphids. Being organics
friendly, and because some of the plants in question are herbs,
I'm reluctant to spray them. My housemates and I have started pulling
off the stems with aphids attached, but it hasn't helped the health
of the plants, nor has it stopped the problem. What other options
do I have to get rid of these little bugs?
plants can easily be infested by insects, as there are no predators
to eat them. If you want to use organic sprays, try Yates Pyrethrum
or Derris Dust.
The pyrethrum can be
used on all types of plants and has no withholding period. Derris
Dust has a withholding period of one day for food crops. When you
apply any spray or dust, take the plant outside. For general health,
it may pay to take the plants outside once a week to give them some
fresh air, or put them outside when it rains to help wash off dust
and insects. The plants will thank you for it!
If you have pulled the
stems and leaves off the plant, it will also pay to feed with liquid
fertiliser such as Yates Nitrosol or Lush Houseplant Food.
