I would never recommend potting mix for growing vegetables. With the rising temperature going into spring and summer the attention to watering really increases. Lots of watering leaches out the nutrients from the potting mix. Just my opinion but the supermarket potting mix is pretty ordinary - yes maybe good for potting shrubs etc but not for vegies. If you're going to use it mix it with real soil - with 50% or more soil.

hi anon, I live in a unit and grow all my vegies in Pots on the balcony with great success, however as you stated pots can dry out quickly and nutrients do leech out , i use seaweed mix once a fortnight and dynamic lifter (pelletised) once a month, i also diligently keep an eye on the moisture lvls, i have found using a good mulch about 3 cm deep on top helps with the moisture retention, Happy Gardening.

Thanks for this info as I too will be growing a lot in containers as I am older and bending is not an option I have anymore as well as on my knees. Oh for the good ol' days when my body was more able. Regardless growing especially things you love is a great and satisfying project
I fertilise before I plant with straights (chemical fert) and water 3 times a week. My fert costs $1-1.5/kg compared to up to $15-20/kg for some of the small fancy stuff. I do take it that people in units have a very limited growing area. And as I said doing pots requires a lot more attention. I also use mulch around most of my plant. I do 12 pallet size raised garden beds half a year for a school. A 12m x 2m home garden 9 mths of the year. I am presently setting up (and will be the operator) 12 garden beds, each 4.8m x 2.5m for a disable group. I'm just finishing off a 6 bay composting system. They are each a pallet high, wide and deep. Cheers

yes you can , however I personally would go with Searles brand, available in 30 or 60 ltr bags, depending on potting mix you might like to add some sharp sand for extra drainage and of course the cheaper potting mixes will require extra fertilizers before planting

I also add a 20ltr mushroom compost and a 1 in 3 mix of sharp sand to help with the drainage to the 60ltr searles premium potting mix, i also use self watering pots for the more susepitable vegies to drying out.
happy gardening :)
