True moles are insect eaters. It is more likely that rats or mice are eating your potatoes. I would try laying rat and mice baits or traps and see what happens. Some of the newer vermin baits are enclosed in small sachets and you will know if they are chewed that you are getting the culprit. Make sure the baits cannot be reached by children or pets and keep laying them until there is no more chewing. All the best.

Poisons? In a garden? What happens when the neighborhood cats & owls eat the mice or rats?

Hi I have some small Kennebac leftover potatoes from my last years crop, they are all sprouting, however the guide says don't plant them till August, can I plant them now or is it just too early.

The guide says don't plant until August. That might apply in southern parts of Aussie or cold places but if you don't have frosts you can plant now. I live where it gets down to 5-6-7 C in Winter and I just planted mine this week. If you live in a low area and might get frosts then ??? - if you live in a higher area and no frosts, go for it. As my previous post said - wait until the eyes start to shoot and then plant. A tip, dig the soil deep, put in all the compost etc - then with a rake dig some of the soil out to make a furrow. Plant the potatoes and as they grow fill the soil back in. And then hill it up also around the plant.

Potatoes are frost tender. If you plant them too early they will sprout and be killed by a frost. Try keeping them in a cool, dark place to reduce sprouting. You could probably plant them in July about 200 mm (8") down and cover them with straw or similar to insulate them a bit.

Is it safe to use old plastic milk crates to grow potatoes in

It is fine to use milk crates to grow potatoes. Line the bottom, and sides if it is open sided, with old denim jeans or newspaper to help retain water then put a layer of growing medium and some old manure or compost in the bottom. position your potato 'seeds' and then put a layer of growing medium over them. Keep adding the medium as they emerge until you are at the top. Consistent watering is very important for any container grown vegetables.

If you mean 'plough or dig potatoes in June' you definitely can. If you mean 'plough the soil and plant potatoes in June' it would depend on whether you get frosts in your area. If you do it would be better to wait until the weather is warmer as frosts will kill the new potatoes.

The information you have here is helpful, but what i need to know is the average growing time to harvest please. The plants are flowering and I'm wondering if that is an indication? We live on the Sunshine Coast and the potato's were planted in October, 7 months ago.

I live in Zone 10A and have been growing russet and golden potatoes in grow bags and large containers here for about three years, and I notice I can plant them year-round and they will grow, just slower in winter, and if we get an occasional frost, it may kill the top, and when temps hit around 100 or hotter the potato tops may die off also. No matter what time of year, my potatoes often grow for a few months and then the tops start to die off no matter the season or conditions, but I don't know why, so when that happens, I'll reduce the watering for a couple weeks and then harvest. I try to do "succession" planting, so I always have some potatoes growing, and am still experimenting with what works best, especially trying to learn more about correct watering for the Zone 10A conditions. I do have better success, producing more and larger potatoes, with 10-20 gallon and larger containers than the 7-gallon fabric grow bags.
