I live in Hawaii. I put in a new raised garden this year in the middle of my yard. There is good air circulation, nice breezes and full sun, plenty of water. I spent a crapload of money buying good soil because there is no soil here. But nothing will grow. I don't understand why.
I use fresh seeds, many varieties. The garden soil is comprised of about 10% topsoil, 50% organic garden soil mix, 20% compost with steer manure and 20% purchased and homemade compost. The only thing that does well is my onions planted from bulb. They are very happy. Our pineapple tops are growing. Melon seeds will grow and then the plants start making crazy flowers all over when the plant is only 10 inches tall. They put out little melons which start, then turn yellow when they are 1 inch wide, fall off and die.
Most seeds won't even start and the ones that do, come up and then do nothing. They usually don't even put out a first leaf. They just sit there being green and not doing anything for weeks.
When I dig down, I feel a nice, crunchy root system, but can't figure out what's growing from it. It isn't grass. Also, when I dig down, the soil is all white and powdery. I assume this is mold. Plenty of mushrooms are growing as well, just no plants.
What could be going on? And should I be picking all of the blossoms off of my melons until the plants are nice and big?
