If you hate using chemicals to get rid of greenfly then try using washing up
liquid mixed with water. Then spray onto the infested area. Another way is
to remove the aphids by hand on a regular basis.
If you have apple trees or you are growing broccoli,
plant Nasturtiums near by as this will help keep aphids away. Planting
Nasturtiums in the greenhouse will prevent whitefly infestation.
If you have aphids attacking your fruit trees or roses, try planting
garlic near to them, as the strong odour of the garlic repels them.
One of the greatest enemies
a gardener fears are slugs and snails. Slug
pellets are effective but may contain chemicals! Below are some
great tips on how to deter & destroy them.
For the slugs, go to your local barber or beauty shop. Ask them
to save the hair they've clipped off their customers. Spread the
hair around your plants. The sharp cut ends of the hair are a devil
on the slugs' soft little bodies.
Protect your potted plants from slugs & snails by placing
mechanics grease half an inch below the top of the pot all the way
around. Or better still use WD40 lubricant .
Crushed eggshells are bad on the slugs, and the shells also
add nutrients to the soil. Birds like eggshells because they add
calcium to their diet so the eggs they make are stronger, and if
a bird is eating eggshells happens to see a bug, well you can imagine
what will happen to the bug.
As you know slugs love to party at night so why not treat them
by supplying the drinks. Place a pint glass with some beer in it
on it's side where they hang out . The next morning you will find
lots of dead slugs , but at least you gave them a good farewell party.
Birds will eat the corpses and be will be singing merrily all day
Another approach is to use a bed of sand around your plants.
Slugs and snails do not like coarse materials and will not cross
it. This has limited applications. But, it works well with fruit
that lies on the ground like pumpkins and melons. Gently lift the
small fruit,and lay a bed of sand so there is at least a three
to four inch perimeter of sand on the ground around the fruit.
Add more sand as the fruit grows.
A Note on using Salt: Some people get a kick out of pouring salt
on slugs and watching them melt. Yes, it works. But, it is not
practical in your garden. Too much salt in the soil is also fatal
to your plants. Use only on paved areas.
