A Heathpool reader is concerned with the feral spread of the blue flowering "Morning
Glory" in Burnside City Council’s area, where it is not a gazetted noxious weed,
so residents are not obliged to remove it, although council does in reserves where they
know it could be troublesome. If you have it ‘going bananas’ in your street, it
can be controlled by spraying with a triclopyr-based spray, but not glyphosate
(Roundup™). Triclopyr-based sprays are sold as "Ax-it™" or any of the
various "Blackberry & Tree Killer" sprays. If you want to spray a
fence-line, better contact Council first. |

The wonderful slow soaking rain we had last
weekend, will now set lots of plants into growth, but it will also show that many of our
plants are suffering lime –induced-chlorosis and they need a supplement of iron
chelates pretty quickly. The telltale signs are yellow veins on the leaves. The remedy is
effective and quick, so don’t waste any time this week. Iron chelates can be foliar
sprayed or root drenched. |

Our region is currently besieged by tiny Whiteflies, as they ravage the vegetable and
fruit crops in our gardens. These tiny sap-suckers leave a honeydew residue that harbours
the growth of sooty mould on citrus and many fruit trees. |

The recent rain has certainly reduced the numbers of Whiteflies in the vegetable garden,
but it’s brought the Black Lawn beetles to the surface of my lawn and for every slow
crawling beetle you see there are dozens of their fat root-eating witchetty grub
underground larvae that you’ve missed. |

A reader’s letter from Myrtle Bank complains of solid fungal growths in her lawn,
which she would like to eradicate. Toadstools, puffballs and mushrooms of all types thrive
in lawns with poor fertility and often poor drainage. |
