It is an objection to some of the poplars, that in any cultivated soil they produce an abundance of suckers. For this reason they should be planted only in grass ground, or in situations where the soil will not be disturbed, or where the suckers will not be injurious. Indeed, we conceive them to be chiefly worthy of introduction in grounds of large extent, to give variety to plantations of other and more valuable trees. They grow well in almost every soil, moist or dry, and some species prefer quite wet and springy places.
