growth charts

| No Comments
When we last checked in on our leaf, on May 8th, it measured 1 1/2" long. On the 10th, it was just shy of 1 3/4".


On May 12th, it measured just over 1 3/4".


And on May 14th, almost 2".


Today, it's just over 2".


That's amazingly steady growth -- about 1/8" every two days. But it's slower growth than I noticed last week, which was about 1/8" every day. Wanna see how it's slightly slowing down?


Judging from this leaf, I might guess that a leaf's growth slows down as it gets larger, but when we take a look at the large leaf right by my window, we see something different. This big leaf was 4 1/2" long on May 9th.


And 5 1/4" on May 12th.


It grew to 5 3/4" by May 14th.


And was 6" long this morning.


Wow! Let's see that in a graph!

Again, my measuring system isn't exactly precise, but there's no doubting that the big leaf is getting bigger faster than the smaller leaf. Interestingly, both seemed to slow down in the last few days. You can see the slopes on their graphs aren't as steep from the 14th to the 16th in particular. I wonder if everything on the tree slowed down in the last few days because the weather changed to cool temps, clouds and rain. Look at this awesome graph that I found at of Boston's weather in the last week ....


Maybe not the most inspiring weather for growing leaves. Could this have caused that slowdown in leaf growth?

I wonder how a tree deals with long periods of clouds anyway. Doesn't sun mean food? But clouds mean rain, which is also important....
