Hi @RebeccaH1,
A warm welcome to the Bunnings Workshop community and thank you for your question.
Assuming good soil quality, consistent watering, pollination of the flowers and overall good plant health, a crookneck pumpkin will typically take 85–100 days from planting to harvest and a jap pumpkin will generally take 100–120 days from planting to harvest.
Check out Planting, Growing and Harvesting Pumpkin for some guidance on caring for your pumpkins.
Let me know if you have any further questions.
Jacob
