Sapling, Yes and NO What I have found when I did it

You want a lid but not one you have to pry off every time so get the blue lids from Loews they snap on and off with one hand. Bring your sap lines/lateral in a hole on the side just under the lid. Leave the hole a little sloppy and use Zip ties o secure the tube by putting the tie on the inside of the tube so it cant pull out Dont let the tube hang down into the bucket more than an inch or two......What the tree giveth the tree will taketh away so dont let it get sucked back into the tree. If you put a hole in the top of the lid and it rains or snow melts on the lid it will contaminate the sap thru the hole. Do not put one tap above another NOPE. If you feel the tree can support having 1-2-3- taps space them out in a pattern that will work next year and every year after.

Putting 3 taps with T's on one line into the bucket will be fine and it is called a leteral
