Pyrethrum Plants
Information
Pyrethrum is one of those companion plants that you most definitely want to have in your maara (garden).
Pyrethrum plants are perfect for companion planting because they stop the spread of sap sucking insects around your garden.
The naturally occurring oils of
the plant’s seeds have been used for centuries as an insect repellent. It has been
used to repel mosquitoes in Africa and it was used to treat lice during the
world war.
The dried flowers crushed and sprinkled around will help deter flies.
In the garden, pyrethrum spray can control aphids, whitefly, thrips, caterpillars, ants and many more.
To make your own Pyrethrum spray for the garden:
- Coarsely grind 1/2 cup of dried flower heads and add 1L of warm water.
- Cover and leave to stand for three hours, strain and add a teaspoon of biodegradable dishwashing soap and one of cooking oil.
- Shake well before use.
- Don't spray in temperatures over 32°C.
- Apply sprays to the “hot spots” directly to the insect's body rather than everywhere.
The spray will kill bees so use it when they are not active—in the early morning or evening. This spray will only remain potent for about 12-24 hours so any that is not used should be discarded after this time. Remember that even though this is an organic spray it will also kill beneficial insects so only use as a last resort.
Pyrethrum is also a stunning flowering plant to have in the garden, plus it blooms all spring and summer.
