Pumpkins are best planted when soil temperatures have reached 15-17 degrees C. This varies between climate zones, Australia is a large country. A soil thermometer is aa good investment to check this. They usually cost around $20.00. If you plant seedlings in February you would need to have about 4 frost-free months to harvest. As for ethics many companies sell what looks good or what people want. Tomato plants are available in Victoria as early as July. They will not do well until mid to late October when the soil has warmed up and many will die. This suits the seedling growers as they will sell more plants as replacements. Having said that if you have a sheltered spot you could get tomatoes going earlier. The best thing to do is to check the planting times on this site relevant to your area and don't be tempted by what's on offer.
