Over the months we've
collected a wealth of hints and tips for the garden. Here's the
story so far
- Comfrey added to your
compost bin will aid decomposition. The leaves are rich in nitrogen,
which assists in the breakdown of dry material.
produces its most fragrant flowers in poor soil. In rich soil
the fragrant essential oils are lacking.
- Plant hyssop with
cabbage to deter white cabbage butterflies.
- Weak or broken stems
of plants can be protected by placing a drinking straw (slit lengthways)
over the break to support it.
- A teaspoon of milk
powder added to the soil when planting your tomato plants will
ensure an even ripening of fruit. When the first truss of flowers
open, add a heaped teaspoon of sulphate of potash to ensure good
red colouring and fruit set.
- Leftover water from
boiled potatoes makes an excellent organic weedkiller for paths
- To repel pests from
your veggie patch, crush the leaves of lemon balm and sprinkle
amongst your plants.
- Annual herbs are best
sown directly into the ground, as most do not like transplanting.
Root disturbance can cause the plants to go to seed. This is especially
true for coriander.
- Banana skins at the
foot of plants will lure aphids away and add a dose of potassium
- Aphids can also be
lured away from your crops by placing a yellow bowl half filled
with water amongst your veggies. Aphids, being attracted to yellow,
will land on the water and drown. Alternatively, cut some yellow
card, smear with petroleum jelly, attach to a stick and plant
amongst your veggies.
- As new shoots grow
on a climbing rose, tie down horizontally. Side shoots will form
right along the cane, and each of these will produce flowers.
If left upright, flowers will form only at the top.
roses do not need pruning for three years after planting.
- Create a natural rose
tonic by fermenting banana skins in a sealed jar of warm water
for a couple of weeks.
- The nutrients from
eggshells are ideal for the garden. Place broken shells in a watering
can, fill with water and leave overnight. Water the garden in
the morning. Alternatively, use the water that you boil your eggs
in as a tonic for your indoor plants.
- To gloss the leaves
of your houseplants, use a mixture of half water and half milk.
- Oat bran scattered
amongst plants is said to kill slugs and snails.
- To avoid getting weedkiller
on cherished plants, place some piping over the unwanted weed
and spray inside the pipe.
- Pine needles can be
used as a mulch around acid-loving plants such as rhododendrons
- Studies show indoor
plants are best watered when it's raining! Plants can supposedly
sense approaching rain and will increase their water uptake.
- Add food colouring
to your weedkiller solution to easily identify which weeds you've
prevent vigorous groundcovers (such as ajuga) from choking other
plants' root systems, 'plant' pots amongst the groundcover and
fill with desired plant.
- Young runner beans
respond well to a heavy straw mulch.
- For some reason seedlings
that spring up on their own are far healthier and rarely get attacked
- Ants are said to never
cross a chalk line. Try it, and see for yourself.
- Humus and compost
can retain up to 80-90% water. A clay soil, which is said to be
the most water retentive, holds only 15-20%.
- For plants in large
containers that are impossible to repot, remove the top 5 to 7cm
of soil and replace with fresh potting mix every two years.
- Sterilise pots that
have contained a diseased plant before reusing. Mix 1 part bleach
with 9 parts water, scrub pot, rinse and leave for 2 days.
- You can test the viability
of old seeds by pouring them into a glass of water. Those that
sink have a better chance of growing than those that float.
- To discourage birds
from eating your strawberries, scatter red marbles amongst them.
Birds will get fed up with pecking glass and leave the fruit alone.
- Slugs and snails love
dead leaves and debris. Regularly clear away fallen leaves from
your garden beds and paths.
- Coffee grounds can
be used as a fertiliser and are also a wonderful pest control
when sprinkled at the base of plants.
of rosemary scattered around the garden are said to repel slugs.
- Tomatoes will lose
their flavour and texture if stored in the fridge. They should
be kept at room temperature, just as bananas are stored.
- To attract birds to
your outdoor birdbath, drop in a few coloured marbles.
- Vinegar poured onto
the affected area will kill grass on walks and driveways.
- Applying a teaspoonful
of salt can individually kill a weed such as dandelion in your
- Keep cats out of your
garden bed by putting citrus rinds on the soil. Alternatively,
try sprinkling with onion and garlic peelings. Mothballs are said
to work on both cats and dogs.
- Soak used tea bags
in water, making a mild mixture to water your plants with once
a month to maintain proper soil acidity.
- Most plants with grey
or white leaves are drought-tolerant.
- Also drought-tolerant
are many sweet-smelling plants. The volatile oil in aromatic leaves
helps retain moisture by producing a protective haze around the
- Because they can make
use of nitrogen from the atmosphere, bean plants will actually
enrich the soil in your garden.
- Plastic soft drink
bottles with their bottoms cut off make great cloches for seedlings.
- Birch trees next to
compost bins are said to help in the breakdown of plant material.
The roots excrete a substance that helps in the fermentation process
of organic matter.
- Buy lemon trees that
are 1-2 years old not 3-4 years old. They are better at transplanting.
- Old Venetian blinds
make ideal plant markers in the garden when cut into small strips.
- Spray pesticides on
still days. If you can smell it, you're inhaling it.
- Hibiscus should be
planted in pots that are as wide as they are deep. As their feeder
roots spread out almost horizontally, tall narrow pots are unsuitable.

it dumps its load of pollen into the flower, thus pollinating
