In this video I talk to you guys about proper nutrients that container fruit trees/vines/shrubs need. The soil sets up the appropriate structure and amendments & water are what these edible fruiting plants thrive on.
Cheapest way is to get an inorganic slow release. Florikan or Osmocote. Plus you want some kind of liquid fert (doesn't really matter what it is), but for optimal growth I recommend going with Alaska Fish Fertilizer + some slow release that's also organic with mycorrhizae within. It's the best for sure, but too expensive for someone like me with 200+ containers.
In addition you want to add in some lime or gypsum to your containers, rock phosphate at the bottom of the container & greensand or ironite for more micronutrients. Again you can find organic alternatives there for optimal performance. Top with worm castings and mulch of your choosing. It's very important to mulch.
This year I'm also experimenting with rice hulls and diatomaceous earth to add some silicon to my soil.
Must be organic and compost based (avoid manures and mushroom compost). Not because I'm a big organic gardening proponent, but because any soil you buy that's inorganic is going to be junk. Nothing beats worm castings or well made compost. In fact anything that's not bark, rice hulls, compost or worm castings is honestly inferior, unsustainable & not worth growing in.
