You can also buy commercially available organic spikes like the ones above
Using these spikes, along with the layering technique that I will explain later, allows you to add addi-
tional amounts of powerful all-natural dry nutrients without frying your plants, which is what would hap-
pen if you mixed these nutrients globally into a soil mix. Dry nutrients like steamed bone meal and blood
meal can be used in spikes very effectively. My spikes are placed close to the container rim, so the roots
have to grow a bit to reach them. In a typical 2-gallon container, planning for a 9-week flowering plant
with a final height of about 2.5 feet tall, I would have my spike hole about ½ an inch wide and about 90%
of the height of the container. So, if my container was 1 foot tall, let's say, my spike holes would be about
10-11 inches deep. A surprising amount of spike blend can be poured into these holes. After filling the
holes, simply add a shredded bark mulch layer on top and water everything well.
