New Jersey Statutes Title 54. Taxation 54 § 4-90

When delinquent taxes are assessed upon unimproved or untenanted land, or on land tenanted by one unable to pay the tax, the collector shall, in person or by deputy, levy the tax by distress and sale of so much of the timber, wood, herbage, or other vendible property of the owner on the premises as will be sufficient to pay the tax with costs. Notices of the sale shall be put up in five of the most public places in the taxing district at least thirty days before the sale, and published at least four weeks successively, once in each week, setting forth the name of the delinquent, the amount of the tax, the day and hour of the sale, which shall be between the hours of twelve and five, and the place, which shall be on the premises. The advertisement shall be published in a newspaper circulating within the taxing district. The purchaser, for the space of two months next after the sale and no longer, may enter on the premises to sever and carry away the property purchased.
