Plant Answer Line Question

Keywords: Recycling (Waste, etc.), Euphorbia

I have a large Euphorbia trigona (also known as an African milk tree), nearly 7 feet tall that currently lives in my living room. I will be moving soon, and it is too large to take with me. I'm concerned about putting it in the yard waste bin and exposing the people who collect it to the irritating sap. Also, is this type of Euphorbia a noxious weed that I should keep out of the yard waste altogether?


I believe it should be fine to put the Euphorbia in your yard waste, as yard waste handlers wear gloves. You could minimize the amount of sap going into the recycling by cutting it into the largest allowable sections, then setting them on a tarp to ooze their sap for a while before adding them to the container. There are a few varieties of Euphorbia that are classified as noxious weeds and would need appropriate disposal, and your plant is not one of them.

Garden Tip

Keywords: Cold protection of plants, Frost, Attracting wildlife, Christmas trees, Recycling (Waste, etc.)

Before you send your Christmas tree away to be chipped for mulch, consider how the tree can be used in your own garden. Cut the branches off the main trunk to place around plants or emerging bulbs that could use extra frost protection. The main trunk could then be used as a stout stake for annual vines planted in the spring. Another idea is to use it as a temporary bird feeding station. Tie on orange slices, suet balls, peanut butter and birdseed smeared pine cones and then stand back and watch the feeding frenzy.
