When I did my last outdoor grow I used regular farmers fertilizer for planting corn, I cut and conditioned my plot just like people would do their garden in the fall. I threw a thin layer of 34-0-0 over the snow at the end of march and that was it for nitro. I transplanted the plants into the nitro enriched soil on the first of June after I cut the garden up with a spade again. This time it was really easy to turn the soil. I put two fert spikes with each seedling that were said by the guy at the local greenhouse would help promote root growth. At first it was a bitch keeping them watered but I discover a mat of fresh dried maple leaves over the soil help hold the moisture then I didn't have to worry about watering anymore unless I felt like it. I simply raked the leaves away and put them back if I felt they needed hoeing. After about a month and a half I got a bag of 6-12-12, and for my single plants I did a half circle on one side with a handful of 6-12-12 and repeat on the otherside to create a circle with the 6-12-12, and the ones planted in rows I went down the rows with the ferts, hand held leaving a light line of 6-12-12, but make sure you stay back from the roots by 6" to a foot depending on the size of the plant. If the plant is smaller use two smaller handfuls of 6-12-12, use common sense. My plants were all about 3 feet tall when they got their first dose of 6-12-12. Two months later I did them again with the 6-12-12. When I cut them down a week before the full moon in October, the plants were all between 8-16 feet tall and totally green and totally healthy. I was getting advice from experienced farmers and local greenhouses. I put down the ferts right before it was going to rain.
