| Question: | "Our greens have become heavily spotted with a running plant which is practically smothering the Bermuda grass on one or two of the greens and is beginning to appear on a few others. Some of these weed patches are 6 feet in diameter. We dislike to dig the patches of weed out on account of the bare spots that would be left; moreover, the weed makes a putting surface practically as good as clover. The roots of the weed form an interlaced mass, and the leaf stems are so tender that it is practically impossible to make any impression by hand weeding. I am sending you a specimen of the weed, and shall be glad for any advice as to how to get rid of it." |

| Answer/Response: | "The plant you send is one of the marsh pennyworts (Hydrocotyle). It is one of three very similar species which occur in your region, but the exact species we can not determine without its flowers and seed. A very similar species occurs in the North, introduced from India, which is illustrated and described in THE BULLETIN, November, 1921, page 220. As you point out, its putting qualities are about like those of white clover. On some of the greens in the South it has been rather favored. Very little experimental work has been done in connection with the eradication of this weed, and all that we can suggest is that the patches be cut out bodily. The infested turf may be lifted to a depth of an inch or more and replaced with good turf. The pennywort may then be destroyed by composting the infested turf for a year or two, or it may simply be spread on the fairways, where the weed is not objectionable. The flowers of this plant are so close to the ground that it will probably form seed even under putting green conditions. After the greens are rid of the weed, care will have to be exercised in keeping them free of it. The seed of the weed is apt to be introduced on the greens again in applications of topdressing or soil, and particularly so if woods soil is used." |
