killed out. 2 When well-rotted stable manure free from weed seeds 

 cannot be obtained, perhaps the best course to follow would be to 

 use a liberal quantity of complete commercial fertilizer in the fall 

 after spraying and apply ground bone during the following two 

 years. 



SEEDING. 



The renovation of lawns by heavy reseeding with grass seed or 

 grass seed containing a little white clover, to thicken the turf and 

 crowd out the dandelions, has been reported as having given good 

 success in some cases. 



Following the use of the spray solution in our experiments, it 

 was found quite necessary to reseed the scars or bare spots in the 

 turf left by the dead weeds. For this purpose a mixture of equal 

 parts of Kentucky blue grass and redtop grass seed was used. This 

 was sown on the sprayed lawn, and well raked into the bare spots, 

 after which a dressing of compost was applied. The success attained 

 by this method seems to warrant the following recommendation: 

 Keep at hand, in a dry place, a supply of grass seed mixture contain- 

 ing equal parts of Kentucky blue grass and redtop grass seed known 

 to be quite free from weed seeds. The two kinds of seed should be 

 purchased separately and mixed at home. The prepared lawn 

 mixtures upon the market are usually of very poor quality. They 

 should never be used unless known by test to be composed of pure 

 fresh seed. The home-mixed seed should be sown on the lawn in 

 the spring (April or May) and again in September following spraying, 

 and well raked into the bare spots left by the weeds. A satisfactory 

 seeding requires five pounds of this mixture for a lot 50 x 100 feet, 

 or one ounce per 100 square feet, at each application. If no spraying 

 is to be done the following season, it is often advisable to add four 

 ounces or more of white clover seed to each five pounds of the mixture. 

 White clover responds quickly and aids in forming a dense growth 

 over bare places where weed seeds may lodge and germinate.
