A Lawn Problem 



h i- often .i problem as to how to furnish grass 

 under trei to have it a e in summer, and 



i. in. d i bat it i- out of the question 

 unless plenty of o ire is available. We have come 

 H i hat there is no drier spot than under 

 a handsome tree on the lawn, the roots of which form 

 bat i- pei Ei ct in that it breaks up 

 the soil formation, as well as absorbs moisture by its 

 thou-. growing rootlets. It was put forth at one 



n with some degree of authority that trees poisoned 



the soil ami tin condition of lawn grass under the same 

 was used as evidence, but we found that in the effort last 



u r to nourish lawn trees by the application of a 



i dressing of ground bone, there are no traces of 

 weakness but on the contrary thi gra - is wonderfully 

 \ igorous. 



It may be thai some soils do not need hone for we 



hear of j ■ results from its use at timi -. but where it 



.i ;rees with the chemical composition there is no better 

 way to rejuvenate. Where much water is used the roots 

 of i he grass are sometimes washed bare and weakness 

 follows, a sure forerunner of weeds, especially where 

 thi' natural manures are used as a rejuvenator. Where 

 plenty of soil from the greenhouse benches is at hand 

 ■ n- hi this time, it is well to mix plenty 

 of bone with it and spread thinly over the lawns adding 

 a sprinkling of grass seed at the same time. We do not 

 screen it first, but -weep the lawns with a broom to 

 i in and in this way all small stones are gathered 

 up with other undesirable particles, and it is a revela- 

 tion how little distances a load of soil will go when ap- 

 m tin- way. 

 Chemical fertilizers are good, but it always seems 

 best to mis them with soil before spreading or the ap- 

 pearance of the lawn will be streaky after it begins to 

 ing to the difficulty of sowing evenly, and it 

 ipplied while the grass is damp as there 

 is danger of injury if the fertilizer is easily soluble. 

 Another source from wdience good material can be ob- 

 i lawns is the burnt rubbish heap. When 

 enough has accumulated it should be screened because 

 tngi r of nails, and if the sod needs leveling in 

 places, roll the turf back far enough to take out the 

 depression, fill up with burnt material, relay the sod and 

 ight edge after tamping or rolling. 

 This is best done in the fall months as earlj as possible 

 i rains are frequent. 

 There has been much discussion about the use of 

 white clover in lawn seeding, but there i- no question 

 that it makes the best lawn though some object to it on 

 tennis con -e it makes them slippery at times, 



but Ei irance even in a dry season the clover
