I live in Cairns in Far North Queensland. Will pumpkins grow in shady areas up here and how far apart should I plant each seed please? Regards Ann

Hi, Central QLD here. Jap pumpkins. This season i planted 2 lots of 3 vines on the same day. One in full sun and the other in a shady area. The full sun ones are growing wee with lots of pumpkins. The ones planted in the shady area grew great looking healthy long vines but not a single flower, male or female. Have turned the water off these ones and will be pulling out in the next day or two. Need plenty of sunshine

Most vegetables need a fair amount of direct sunlight a day, 4-5 to 8+ our a day. In shade you will have weak looking plants. It tells you in the notes how far apart. Set the climate zone to tropical for planting times.

I also have seeds germinating from my compost and have at times so much produce have taken great joy in giving them away and hearing about the joyous results. I am out most mornings 2 hours after sunrise when the male stamen is all fluffy with pollen and the female has ants crawling around inside. I pollinate myself by gently picking and trimming the male flower because if I leave it to mother nature my crop is very small. I usually use 2 or 3 male flowers on one female just in case. Recent rains have not been helpful for flowers at all but 1 week later flowers are appearing and just this morning I watched a bee laden with pollen flying from flower to flower. It was so laden it had trouble flying. I love mother nature she is the best for people like me.

Every year I get pumpkins pop up from compost that we put around the fruit trees. This year I have 10 large ones, and a number of small ones that might mature if it’s not too late. They are a mixture of Queensland blue and Kent. No butternut this year. Last year we spread the compost out the front and did not get a single fruit, otherwise we average 10 a year.

Last year the compost may not have had pumpkin seeds in it. If it did the seeds may have gone rotten. Or they were too deep in the soil. Why not take a few seeds from the pumpkin you eat each year, dry them out for a couple of weeks and germinate them next year, Put the dried out seeds in a little plastic bag and store them in an air tight bottle in the fridge. You can produce about 3-6 pumpkin per plant if the bees are active or hand pollinate.

I have planted pumpkin seeds from last years plants every little bit of space I can find in my yard this summer, plants are coming up everywhere and noticed the first pumpkins growing and looking very healthy. I was wondering if I can put a illtle bit of chicken manure around each plants base, as I think it,s the best thing to add to the garden, but away from the stems to give them areal kick in the guts?

You should have done this in preparing the soil before planting the seeds. You need composted manure. Fresh manure won't do much for weeks until it is composted. Your plants will tell you how they are going. Good strong green looking plants don't need a good kick in the guts. Pale yellow weak plants do not have enough fertiliser.

I have plenty of runners on my pumpkins when can you start cutting these off They are greys and green colours. Why are you not supposed to grow near potatoes.
27 Jan 20, anon (New Zealand - temperate climate)
You don't cut the runners (vine) off, how do you expect to grow any pumpkin if you cut them off.

Hi Something is eating the pumpkin leaves They were planted around mid November so they are around 6 weeks. Thought it might be snails but no sign of them. Any suggestions in what to look for? Cathy
