I'm having problems with grub's in my yard and garden. Has anyone ever used a spray called milky spore. If any one has how long does it take to get rid of them. The moels are reeking havock on everything because of them. Dogs digging after the moels is a completely different story and problem. Any advice would be appreciated thank you.

Earth-friendly beneficial nematodes seek out and kill grubs and other soil-inhabiting insects. They come on a sponge (invisible to naked eye) that you soak in water, put in a sprayer and spray your dirt or lawn. They will multiply over time and continue to kill grubs You can buy them online or at your local nursery.

my roma tomatoes have got a big brown spot on the very end just as it starts to show colour, what would you say that is ?

Looks like is lacking calcium, normally we put fertilizer but we forget to put calcium, get some dolomite or some rock dust.

Use Epsom salt - a teaspoon in the hole at planting and even sprinkle another on top of the soil a few weeks later.

Blossom end rot by the sounds of it. Buy some Epsom Salts and put in your garden - from supermarkets. Couple of $$ for 1 kg.

Epsom salt is magnesium sulfate and doesn’t address the lack of calcium. For this coming spring you can buy calcium at Bunnings or your nursery but if you add finely crushed eggshells in your soil and let it degrade over the winter months you will not have to buy calcium again. Boiled eggs water and fish bones buried in soil work wonders against blossom end rot.

Growing tomatoes for years now and keep getting small holes like a grub mark as the fruit is rippening and then goes rotten what treatment if any can be used

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
