Try a new area. Dig the soil and add compost/manure or fertiliser. Add some Epsom salts to the soil - buy at supermarket. As the plants grow up to 600-800mm tall, pick off the bottom few leaves and suckers. Always leave the top 6-8-10 leaves. Tie plants to a stake each 300mm in an 8 configuration around the plant and pole. Water in the morning and water at the soil level. When a tomato plant grows and you prick fruit, the bottom leaves die. Little plants need a little water each day or two - big plants need a good deep watering 2-3 times a week, unless it is summer they may need more. My toms are 1.8m high, green as anything and not a dead leaf yet. Fruit developing.

These tomatoes were seeds from seedlings given to a seed seller who grew them out and harvested the seeds and sold them. They are from Guyra Glasshouse (NSW) - biggest tomato grower in Aus I read. These plants have been unbelievable. I grow them on trellises 6-7' long - 3 plants to a trellis. I have 3 trellises about 2.5' apart running N -S and another trellis at my house. The middle trellis of the 3 hasn't produced too many tomatoes - shaded by the others but gee have all the rest produced heaps. I don't know what variety they are (a hybrid) but they produce a lot of fruit and no disease or grubs. Have picked about 40kg and still have approx. 25-30 kg to pick.

re: end rot_ always put calcium of some kind in the planting hole then feed with powdered calcium and maybe spent coffee - diluted, a couple of times in the growing season. I collect all my eggshells and use, powdered, for all the mandrake plants, especially the ones in pots - once a month application for potted plants.\

Can I plant my tomatoes now and til April 24 without any damage to my plant. I plan on putting straw around them for added protection

I have been planting tomatoes in my veggie patch, but the fruit never goes a nice bright red, they are always blotchy orangey red. I have tried different varieties, but they all do the same thing. Is it the soil, or too much sun, or the bore water which is quite hard? They taste ok, just look unattractive. I was going to try growing them in pots this year, then at least I can rule out the soil.

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.

Hi David :) I am in Northern NL Canada and if you are not doing greenhouse tomatoes, actually...the Artic tomato is perfect for zone 3-4.
