Thanks for your response. Your original post inspired me to go got the tree seedling pots. My thoughts, and would appreciate your experience, is to plant directly into exactly the same final media in the pots, as was used in the trenches.
I’m thinking of slicing the sides of the pots and holding the bottoms together with tape. Thinking about popping the seeds about 3 weeks prior to anticipated transplant date June 1. Again, size is an issue. The final transplant space is a 20’x36’ hoop house located just shy of 44 lat. The seedlings wii be transplanted into trenches previously prepared with am excavator, 40% compost, 30% coir, 20% vermiculite. Last year used fabric bags, Want to consolidate veg space. Thoughts much appreciated.
