Aphids are the enemy to all gardeners and farmers. As everything in our world has its place in the ecosystem, it wouldn’t be right to say I hate them. Nonetheless, I do find them terribly annoying!
The cause of aphids appearing is due to an in balance in your soil. Currently, our fava bean plants are attracting aphids. Out of all the things we have grown this season, the fava beans are the most nitrogen rich, which the aphids love to feast on.
However, since aphids rarely stay on one plant, and do not stop until all the plant leaves are destroyed, it is beneficial to deal with the issue as soon as you see the first few aphids.
We used the homemade natural spray below to get rid of the aphids. We found it to be very effective. Since our spray two weeks ago, the aphids have not returned, and we’re super happy.
I hope it stays this way!
Natural Aphid Spray
What you need
– one large onion
– a bunch of chives, about 500g chopped
– 6 large garlic cloves, crushed
– garlic oil
– one large bowl
– a vegetable sprayer
1) Chop up the garlic, chives and onion into small pieces.
2) Place in the large bowl. Add enough boiling water to cover all the above, I use about two litres.
3) Cover with cling film, and then leave overnight in a dark space.
4) The next day, we need to reserve the liquid from the mixture, and no longer need the chives, onions or garlic. I found the best way to do this is with a colander, which can be used to drain the liquid into a different bowl.
5) Pour the above liquid into your vegetable sprayer. Add a 1/4 to 1/2 teaspoon of garlic oil. Then add three times the amount of water that you added in step 2. As I added 2 litres, I would now add a further 6 litres of water.
6) Shake the vegetable sprayer really well to mix everything up.
7) Spray your plants.
- It is helpful to dedicate a separate vegetable sprayer to this spray, as the garlic oil is strong and the smell is difficult to remove.
- You can store leftovers in the fridge in sealed plastic bottles. If doing this, only add garlic oil to the amount of the liquid that you will use immediately.
- Your plants will smell garlicky, but this will disappear after a couple of days.
- You can continue watering the plants normally.
- For a long term solution, I suggest a soil analysis so you can have the best balance of all nutrients.
