Help with new Mango tree
Hey,
I recently purchased a grafted Cogshall mango tree from a nursery and I live in a less than ideal climate (Northern Canada). After giving it a few weeks to settle, I transplanted from a nursery pot to a ~5 gallon with a mix of potting soils, coco coir and perlite. Since then the older set of leaves have started to brown and wrinkle, and even some of the newer leaves are getting some holes/rips in them. I've tried to show both issues in the pictures, and also note that the leaves are more on the yellower side than what the pictures show (iphone has a tendency to oversaturate colours). Additionally, there has not been any new growth yet.
I wanted to get people's opinion on what the cause is likely to be, and what I should do about it.
Transplant stress - If this is the case, then I should just stay the course, make sure it is watered appropriately and gets plenty of sun.
Cold stress/wet roots - We have been getting a mix of 15-25C daytime highs, with 5-10C nighttime lows. So it's possible that it hasn't been enjoying the cold temperatures. In addition to this, we've had some rainy weather which hasn't allowed the soil to get much for wet/dry cycles. One thing I could do is bring it back inside into a grow tent with lights until the weather gets nicer. Or, just keep it under an overhang to allow for it to dry better and wait out the colder temps.
Unsuitable soil - My mixture may have been too heavy or possibly not the right nutrient mixture. To fix this I would have to pick up some new more appropriate soil and re-transplant it. Maybe with a different pot type which allows for better air flow.
Thanks in advance for any suggestions and advice that you can provide.
