Q.I have 2 tree collards, currently in 5 gallon pots from nursery. Can i plant in a larger pot (clay) instead of ground
I have 2 tree collards, currently in 5 gallon pots from nursery. I don’t have a large garden. I wanted to plant in a 15-20 gallon terra cotta clay pot. I drove over 30 miles to purchase these tree collards (very hard to find in California), so i am very scared if i transplant them in a huge pot, they may die? What type of soil should i purchase? I hope i don’t have to feed these tree collards with chemical fertilizers in order for them to grow well. Clearly, i don’t know much about planting. Can you please help? Also, if you can recommend a great potting soil that is safe that would be awesome! Thank you greatly for your time and for this awesome site.

The container size will be just fine. What I would do is use a mix of potting soil and compost. This will supply the nutrients as well as provide the light soil for it to grow its best. This will cut the need to feed it, as you can just add more compost if it needs a boost later.
