how long does it take for carrots/pumkin/corn and watermelon to produce ripe fruit?

Question

My garden is about 12 weeks old and it really is thriving. I see flowers on the vines and one tiny corn husk. How long does this take from now to produce ripe fruit/corn?

Answer 1

Much of the answer depends on the weather and growing conditions in your area. The seed packet does give you a basic amount of time but it doesn't account for the other factors . Like too much rain not enough rain or hose watering. The water does make a difference. Rain gives it a much better growth than hose gardening. Using the correct fertilizer or no fertilizer at all. Specifically name of the plant ie; charleston grey is very large. All of these factor contribute to the answer

Corn needs to be planted closely in a group to facilitate pollination.

Carrots are a biennial plant, which means that it completes its life cycle in two years. During the first year, it stores food (the root) to prepare for what it will need to produce flowers and seeds in the second year. Alas, carrots don't get to experience the second year very often because we harvest them before they reach maturity.

The seed packet will tell you. They will take quite a while. Generally corn is ready in August, watermelon in July/August and pumpkins take longer and prefer cooler weather. The carrots about 2 months.
