  •  food for beneficial insects

    Last winter, a nursing student joined us at Grandview Community Garden for a few hours,  She sowed some tiny seeds of alyssum around the lemon tree. Now the alyssum is flowering, and will be attracting beneficial insects like tiny wasps and hoverflies to the garden to drink the nectar and eat the pollen. We hope these beneficial insects will stay in the garden and lay their eggs on caterpillars and aphids.

  • WORMS

    2170548515?profile=RESIZE_480x480Worms are good! They help to make compost (decompose garden waste) and aerate the soil, helping plant roots get the oxygen they need.  Their droppings and wee are excellent garden fertilizer - that is why we sometimes farm them

  • Rats & Mice2170552278?profile=original
    Rats and mice are the most numerous mammals on earth, so you've probably seen them before! 

    They love to eat seeds, so keep your seeds in screw top jars or a box they cannot eat through. 

    Given the chance, rats and mice will also eat flowers, fruit and your stored crops, such as kumara and nuts. In the photo (right) you can see where a rat has eaten a potato I was chitting.  They also eat insects.


    The first time I saw a rat it ran up a sunflower to eat the seeds!  I have also seen one climb a tree to get into a nest: they eat both birds and their eggs.  The pest proof fence around wildlife sanctuaries like Maungakawa uses a mesh with holes no bigger than 6 mm to keep young mice out.

    A NZ designed trap called Nooski is said to be one of the most humane ways of killing them - there is a podcast interview with the inventors on Radio NZ.  Some cats and dogs will also hunt and kill rats and mice. 

    Rats and mice are rodents

  • time to look for slugs

    Look for slugs under pots, logs and leaves during the day. When you find them, squash them. Slugs breed fast and will eat your spring plants, fruit and flowers.

  • NZ Garden Pests & Diseases2170563037?profile=original2170563458?profile=RESIZE_480x480

    Clare recommends Rob Lucas's book, Managing Pests and Diseases: A Handbook for New Zealand Gardeners as a guide to help you identify what is damaging your plants.  It has many colour photographs.  

    Both Hamilton City Libraries and South Waikato District Libraries (Tokoroa & Putararu) have copies of the book that you can borrow for free if you live in their area.

    Photos: Cicada insect and skin that has been shed. Cicadas make the loud noise you hear in summer and autumn during the day.

    Cicadas lay their eggs in twigs (small tree and shrub branches), leaving a herringbone pattern.  This weakens the twig: it will often eventually break off.  In most cases this is not a problem.  In rare cases where lots of cicadas have laid eggs on a young tree, the tree will die. 

    • While Lucas's book is great for identifying pests and diseases, the ways he suggests of controlling them are not always the kind of methods that organic gardeners would use.    

  • Where the wild things are...

    If you are out in your garden at night (perhaps harvesting snails for the chickens), you may hear a rythmic scraping noise.  This is likely to be a native male weta, telling other weta to keep away from his territory.  Weta are mostly nocturnal - ie active at night.  They are an insect related to crickets and grasshoppers.

    This week is Conservation Week and you have the opportunity to see one of our endangered giant weta at either Hamilton Zoo (11-11:30 am, or 2 - 2:30 pm daily) or at a free public Royal Society Lecture tomorrow night at Waikato University.

    Weta look fierce, but like most of NZ native creatures, they would rather get away than try to hurt you.  They rest in dark crevices during the day.  Gumboots left on the porch can seem like a safe place to hide, so if that is where you leave your shoes, check they are empty before you put your feet in!

    The Department of Conservation (DoC) are encouraging us to leave a small part of our gardens wild to give native creatures, such as weta and lizards , a place to flourish.  Here is some advice on making a lizard friendly garden.

      

    • Tree Weta2170551632?profile=original

      The type of weta you are most likely to see in your garden is the tree weta. 

      The females have a long 'spike' sticking out of their rear ends: it is not a sting, it is an ovipositor - a tube used to lay eggs in soil.  You are most likely to see weta in April-May when they come down to the ground to lay their eggs.

      Like many NZ creatures, if they feel threatened they tend to freeze (be still), or in some cases flick their spiked back legs up (see video clip below) which makes them look bigger.  If  it does this to you, move back - give it some space. Given the chance they will hide rather than bite or scratch you. 

      You can also hear the sound weta make in the video clip below.

      Weta are eaten by many creatures, so many species of weta are threatened: don't kill them!  Predators (creatures that eat them) include: bats, reptiles, birds, possums, hedgehogs, rats, mice, stoats and cats.
