Hello wonderful people with green thumbs! I've managed to grow an adorable avocado tree from a supermarket avocado pit. I don't know what I'm doing and I'm usually awful with plants so this was truly a miracle but I need some help please. My tree is now about 42" and is in a 10q pot.
We're located in a small apt in New York City and since the winters are too cold for my little tree, we're trying to continue in pots until I can find it a good home in a warmer climate.
I have 3 questions please; 1. I've switched to the pot it's in few months ago but now it's much taller and has bigger roots so I'm afraid to mess it up. What is the best way I can repot to keep my little tree healthy? And how deep should I place the pit? I didn't have a support stick before since it seemed sturdy but now that the top leaves are very big, it began to bow and now I have a stick as well. You can see the new pot in the picture. (On the bottom it says 25q) I'm hoping it will be enough until the winter when hopefully we'll be moved into a house so I can get a much bigger pot. 2. 4 of the leaves by the top are dried midway. The lady at homedepot advised me to cut the dried parts. Should I? What caused this? What can I do? 3. The lady gave me Nature's care organic and natural tomato, vegetable & Herb plant food. Would my little tree like this food? Or is there one better suited for its needs?
Thank you so much!! Whatever advice you can give me will be highly appreciated! Please help my tree! Ps. I dont know how to add more pics but I'll try to do it in replies. Sorry!
ADDED INFO FOR STORMY
Hello Stormy, I am so sorry! I should have mentioned that this isnt the regular spot for my tree. It sits in a windowsill in front of a VERY bright window facing north. (I only have any windows facing north). It was originally in a 3q pot and when the leaves began to grow really big, I switched to the pot it's in now. This was in February. I cant remember which type of soil it was but it was a plant one from homedepot and I think you might be right about it having some type of fertilizer or something in it cause it suddenly grew very fast and tall. I thought it was the new pot. The leaves continued to grow very big and dark green. The top leaves curling up dry happened only couple weeks ago. And I have 2 theories as to what might have caused it; either the sudden temperature rise and long exposure to sun without enough water OR that it was caused by my stupidity when I accidentally used the same watering can I use to add treated water to my aquarium. (It is treated by a chemical mix called Prime which removes chlorine, and chloramine and detoxifies ammonia). If there was traces of it in the water maybe my tree got a tiny tiny bit. I switched to a new watering can since then (might explain why the top leaves are all normal and I have new growth coming along)
I never used any food fertilizer etc. I think I might have stuck 2 miraclegro food spikes in there once long ago. I will return the soil and fertilizer and get one that you recommend. Do you think i should continue in the pot its in? Since it grew so fast and tall I thought it would need more space to continue. However I can only keep it in the windowsill if it's in this pot. Anything bigger wont fit. I will make sure to lower the shades so it doesnt get direct sun. And if you recommend I repot then I will place it to the spot closest which is the floor by the window.
When you said cut the leaves to the next leaves.. do you mean i cut off the entire plant body from the leaves up or just trim the leaves? There are normal leaves above it and some new growth coming up. Thank you so much!!!!!
