i am a first time watermelon grower and i can say wow, the plant (1 only) is going wild. Does anyone have tips on right fertiliser/care

Yes, Gillian.... The RIGHT fertiliser for growing any fruit beautifully would be "MIRACLE" brand fertiliser ...You can easily get them from Bunnings.....Good LucK!!!

Compost is much better than fertiliser for melons, marrows and cucurbits. Fertiliser actually depletes the soil of life and is generally over applied to veggie beds and either stunts plants or burns by trying to force them too much. Your edible plants will always flourish in good quality compost, especially water melons.
