I grew up in the 70’s and remember loving the ad campaign for California avocados (you get a free plant with every avocado!). For a long time, I didn’t eact avocados, so every time I saw someone cutting one open, I’d ask for the pit. I’ve tried many times to grow them and would get the beginnings of a plant, but then they would die of neglect. I had the best luck with a “greenhouse” that I made out of the plastic container from a grocery store roasted chicken. But, when they sprouted without me realizing (AKA neglecting them), they were cramped by the height of the container. So, I decided to make individual containers that were taller.
I started by saving up a bunch of 1 liter water bottles.
Then, after removing the labels, I cut them apart, using the bottom ridge line as a guide.
Next, I premoistened some potting soil and packed it into the containers, filling each base about halfway.
After that, I pushed the pits in to a depth that was about half of the pit.
Finally, I used clear packing tape to tape them back together. This was actually the hardest part… so there isn’t a picture of it
I’m going to plop them on a windowsill and ignore them for a while. If I see them looking dry, I’ll add a bit more water, but I expect that they’ll do fine without me for a while.
