How do you control fungus in pumkin vines

Hi Phil, You can prevent fungal attack simply by watering directly to the base of the pumpkin plant & never spray watering. Its difficult because the plant spreads so I stake lengths of 25mm poly at planting so I don't have to walk through the plants & simply use a funnel in the end of the poly to deliver water morning & night. A weekly dose of seaweed extract is given the same way. At the end of the season when the plants are mature you can spray a little copper but I generally remove the pumpkins, eat the tips & compost the rest. Hope this helps, Al.

Phil Ware sub tropical small pumpkins forming then dropping off. I hand pollinated all new pumpkins. Only one grew large. For space reasons (small garden) I cut the pumpkin from the vine and kept a length of vine attached. When might cut up and cook soup etc?

Most common is the Jarrahdale pumpkin - plant Sept to Dec and don't pick until vine starts dying - about 18-20 weeks from planting. Good fertile soil, lots of sun and plenty of water.
