I kept few seeds from a watermelon I enjoyed in January. I'm going to plant them next month. I'm so looking forward. I'm in GP.

Is July too late to plant or transplant? Or should I wait for August. Wanted to get a plant or seeds as a late Father's day gift but thought I should ask. It can always get a birthday present in August

Check the monthly planting guide here. Better to plant in the spring.

I bought a melon plant from bunnings and I'm planting it separated from another plants for a good grow but this is the 4th week and it's only a foot long now the growth. So I'm not sure if it's normal I thought it should be fast growing like pumpkin plants? Please waiting for your response.
