Lisa, it means that they should not be planted in the same bed.

Is is time to plant tomato seedlings out in the patch yet? Also, a patch I have does not get full sun till the middle of the summer. Should I delay planting tomatoes there?

Basically from the start of October to early November is considered tomato planting time in Melbourne but exactly when to plant out your seedlings depends on the microclimate of your garden. If your veg plot is sheltered from cold wind and gets lots of sun, or you have raised beds (which warm up quicker than an in-ground garden), or you are growing your toms in large pots (again, warmer than in-ground beds), then you can get away with planting them now. I have a heavyish clay-based soil which tends to take a little longer to warm up, so will not be planting mine out until around the end of this month. As far as planting in less than full sun, the minimum recommendation for plants like tomatoes is usually given as 6 hours of sun a day, so your patch doesn't necessarily need to get sun from dawn to dusk. If it's currently getting 6 hours you can proceed as per usual. I have a spot in my garden that is shaded by a shed in winter/early spring, which I'll be using for a tomato plant this year. I'll pot up the tomato seedling destined for that spot (an early fruiting variety) into a bigger pot as necessary, and plant it out mid-November, by which time the space gets about 6 hours and the seedling will be a good size.

My dogs like to eat manure and blood and bone drives them nuts, so last year I used mushroom compost together with liquid fish fertiliser on the tomatoes. Had a staggeringly large crop.

Is it possible to use mushroom compost (alkaline) with tomatoes (liking acidic soil)? Has anybody used this technique and what were the results?

DO YOU PRUNE GRAFTED TOMATOS THE SAME AS A NORMAL TOMATO

I don't prune tomatoes at all. Diggers Club did a comparison of pruned vs unpruned and found no difference in fruit production.

My tomatoes have been good but, because of all the rain, they've stopped changing colour. Should I just pull up the plants and let them ripen indoors?

You can over feed your plants but that usually won't kill them. For the wilting, the reason being is either it is getting too much sun and not enough water or justis not in any sun at all and is being over watered. Tomatoes like part shade but most sun and that's what I have found that works best.

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
