January means it’s scion exchange time. The Monterey Bay chapter has already had its scion exchange, but more are on the way. You can see here: https://crfg.org/2019-scion-exchanges/
What’s a scion? Most fruits we eat come from plants whose seeds are genetically very different than their parents. So to have the same quality of fruit, they need to be propagated clonally. That is, a piece of that variety tree/plant gets grafted onto a rootstock. The scion is that piece.
Most CRFG Scion Exchanges have demos where you can learn how to graft.
