Are Wasps a pest or garden natural pest control

August 28, 2008

Wasps are fascinating eusocial insects with a queen and many infertile female workers. I think they are the tigers of the air. Some people consider wasps a pest because they eat the fruit and drink their beer whereas others consider them a welcome garden natural pest control.

As the season comes to an end, they prepare by producing Virgin Queens to carry the genes in to the next generation.

Instead of only producing workers to tend the nest, the workers of colony decide to feed some the larva with protein to produce Queens. They want meat. Prey can be caterpillars, or insects, some they rade from spiders webs. They chop the caterpillars into manageable pieces and fly back to the nest where they are chewed up and fed to the larger queen larva. It’s only the larvae that can eat meat, Wasps can’t. The larvae regurgitate a sugary meal in return for being fed by the adult wasps.

Wasps are very useful as natural garden pest control because they eat a large number of garden pests such as caterpillars, aphids, queen ants.

Wasps will often make their nests in our loft space, where it is dry and out of the way of danger or under tree roots and sometimes they will excave underground mouse holes. These can be more of a problem because if they are disturbed by people walking on the lawn near the nest or disturbed by the vibrations from a lawn mower, they are more likely to go and defend their nest and sting whatever they consider a danger.

A powder can be sprayed in to the nest – best to do this at night when it’s dark and all the wasps are inside the nest and less able to come out in defence of the nest.  If the colony is causing no danger to humans or pets then best to leave them alone.

In the northern hemisphere only the Queens survive the winter by hibernating and emerge the following spring to start a new colony. All the workers and drones will die.

In New Zealand however, the weather allows the wasp colony to survive all year round and our European or German wasps are causing havoc to their native wildlife.

The reason for pruning. How to prune and what’s the point of deadheading

August 25, 2008

To grow attractive looking perennial plants most need to be pruned otherwise they become too big, untidy and produce unimpressive flowers.

Many people new to gardening are nervous when it comes to pruning.
This is because there’s a baffling amount of information on pruning and to make things worse some of the information seems to contradict the other.

If you think of it, herbivores have been nibbling at plants for millions of years, so plants are quite used to being nibbled and cut. It’s been suggested that the saliva actually stimulates growth.

Pruning encourages new productive growth

The reasons for pruning.
Pruning encourages new healthy growth.
If you cut out dying and diseases wood, the plant can instead of fighting disease will put its energy in to new productive growth.
Pruning will keep the plant shape and size in check.
Pruning will keep unwanted seed dispersal under control.

Deadheading encourages a second flush of flowers

Deadheading encourages a second flush of flowers

Pruning / deadheading will encourage a second flush of flowers. The reason being, when you deadhead a flower, the plant can no longer put its energy into seed production. Reproduction is the second imperative so if the plant can’t make seeds because you’ve cut the fertilised flower off, the plant will put it’s energy into producing new flowers in which to do so.
Although flowers are attractive to our eyes, the real function of a flower is to attract insects to transfer pollen from one flower to another, resulting pollination and seed production.
Deadheading basically removes the ability of the plant to produce seeds and so it produces another flush of flowers in order to do so.
Deadheading will produce new flowers in the growing season. Deadheading very late in the season won’t produce further flowers as the plant reacts to the falling light levels and temperature changes and so it’s programmed to shut down ready for dormancy over the winter period.

Some plants won’t produce new growth if you cut in to old wood.
Cut at an angle just above an outward facing bud.
Use sharp secateurs to make a clean cut.  A clean cut will quickly heal quickly whereas a blunt blade will bruise the stem where die-back or disease can set in.

Pruning vines. Some plants like vines will weep sap profusely if you cut in the growing season, so it’s best to cut when the vine is dormant i.e when the sap not rising.
Clematis pruning. There are basically four pruning techniques for pruning clematis.
Rose pruning. There are 4-5 different rose types all needing different pruning

Techniques.
Pruning wisteria. The Wisteria like many vines only produces flowers on the branches that are in direct sunlight. The flowering buds are stimulated to form by the sunlight. Wisteria are therefore pruned twice a year.

Growing Sweet Corn and how you know when to harvest.

August 24, 2008
Sweet corn 'Butterscotch' best eaten just after it's picked
Sweet corn ‘Butterscotch F1’

Plant your sweet corn 2cm deep, in a frost-fee, well drained, fertile soil and sunny position in your allotment or garden. Ideally the pH should be around 6.0 – 6.5

I first soaked the dried corn seeds over night to allow them to absorb water. Then kept the corn in damp kitchen paper for a few days to see which were viable then selected the ones that had started to germinate.

Ideally your plants needs at least eight hours of sunlight a day.
To germinate the soil temperature should be about 60 degrees. You can start planting in pots in the greenhouse then transplanting the seedlings when the soil is warm enough.

Don’t mix up different varieties together as you’ll get cross pollination. Plant the same variety of corn in a block 30cm apart and rows about 60cm apart. The plants need to be close enough together to ensure wind pollination and to ensure they fertilise each other to produce corn on the cob.

Water well throughout the growing season and don’t let the sol dry out.
If our British weather ever gets too hot, water more frequently. The sweet corn will not grow well if it becomes to dry for long periods.

The time to harvest your sweet corn is when the ‘silks’ are brown and dry and you can pierce the kernels with a finger nail. If the liquid is clear it’s not quite ripe. When you get a milky liquid then it’s the time to pick your corn on the cob by twisting the ears of corn which should snap off the main stem.

Peel the husks off before boiling your corn on the cob.

The best time to harvest your corn is in the cooler hours of the morning.  Store them in cool temperatures, the cooler the better.

You will get the sweetest flavour if you eat your sweet corn on the cob as soon as possible. BBC prestenter Carol Klein suggests even taking a pan of boiling water to the plant and popping the cob in to the boiling water within seconds.
Boil for 6 minutes. Spread butter and a bit of salt to your taste. Delicious

The variety photographed is Butterscotch F1

In wet weather conditions your courgettes might not get fertilised due to the lack of insects to pollinate the flowers.
