Hi, back in October, me and my friend went to the park and picked up a couple of acorns. We put them in the fridge for a month in a plastic bag with wet cloth. We where able to sprout the acorns. I had mine for a week and I needed to bring it home for a few weeks in between university clinicals and I had to leave it in the car for a few hours. It died since it was winter and froze. However, about a month later a new sprout started growing and I was able to save it. It has now grown leaves for a few months now but its growth has stunted. I can see a little bud coming at the top but its been there for 2 months. Now some of the leaves have wilted and it hasn't grown. I was wondering if any of you guys have tips on how I could save it and kick start its growth again since i'd like to plant it in the yard next summer and have an oak tree .
Here is how it looks right now (kinda looks like a dying bonzai) and how it looked 1 and half months ago. I will also include how my friends oak looks like (its .
the nicer one)
