They may not be good companions but if both are doing wellit's not going to cost you anything to let them go. If the melon roots are intertwined with a potato you may have to leave that potato until the tops of both die down

Try ordering yellow watermelon seeds from Livingseeds. Their service is amazing: They stock a good selection of watermelon varieties.

The soil here is extremely sandy so we make compost and loosen the soil (basically make a hole for seedlings and enrich it with 300ml of compost). I've never planted watermelons and would like to (cabbage and radish work wonderfully here). What irrigation is better - overhead or drip? How much water per day/week? (we plant without wastage). Is it okay if I use mulch - we do it for everything else to preserve the soil. It gets to about 45C in summer... is that okay?

My daughter (7) planted her watermelons seeds several weeks ago and has been watering and tending to them ever since. Today, we noticed a little sprout- very surprising I have to say! Will this melon grow? If so, how long till we see a melon? We live in South West of western Australia
