"The bur oak, scarlet oak and white 

 oak are all <,'oo(l trees tliat are known 

 to succeed in the latitude of Woostor 

 and over the entire state. Less well 

 known but equally choice and desirable 

 arc the chestnut oak, the willow oak. 

 from the south, and the shiufjle oak 

 (Quercus inibricaria), sometimes called 

 tlio laiirel oak, which is one of the rich- 

 est and handsomest of all oaks in its 

 ;^arb of glossy, dark f;reen leaves. The 

 willow oak, thoujjh most abundant in 

 the southern states, has proved to be 

 entirely hardy and satisfactory in Ohio. 



Elm, Ash, Linden and Maple. 



"For ,'illuvial lands and all rich soils 

 the American white elm is unrivaled in 

 majesty and grace. A moderately fast 

 ijrower, the elm lives to an extremely 

 idd age, its beauty increasing from year 

 to year. For street planting the elm is 

 unexcelled where soil conditions are 

 suitable. 



'•The white ash and the American 

 linden or basswood have a high land- 

 scape value and are known to succeed 

 over a wide range of country. 



''Probably no group of our native 

 trees has been more popular for lawn 

 planting than tlie ma]ilcs, particularly 

 the Norway maple. The most lasting 

 of our native species is undoubtedly the 

 sugar maph>, which ought always to bo 

 'ransplauted before it exceeds two 



have high value for street planting 

 througli their resistance to dust, gas an(i 

 smoke. Foremost of these is the orien- 

 tal ])lane or European sycamore, a large, 

 spreading species somewhat similar to 

 its American j)rototype, but in most re- 

 gards a finer, more desirable tree. The 

 foliage of this plane is quite free from 

 the fungous diseases that disfigure the 

 American tree, while its head is much 

 more adequately supplied with limbs 

 and branches. The Norway maple is 

 another good smoke and gas resister, 

 whose merits appear now to be pretty 

 generally recognized." 



The ginkgo has already been referred 

 to as a good tree for city use; it is gen- 

 erally both healthy and handsome in a 

 city environment. I'erliaps tlie Chinese 

 cork tree, rhellodendrcui amurenso, 

 though omitted from the agricultural 

 buUetin, might appropriately be men- 

 tioned in tliis connection, since it flour- 

 ishes luxuriantly in city conditions, or 

 at least in Chicago conditions. It is 

 like the ginkgo in being remarkably 

 free from pests, but is an absolute con- 

 trast to the ginkgo in habit of growth. 

 It has large pinnate leaves and its 

 br.'inches are wide-spread, forming a 

 round liead. It is naturally somewliat 

 irregular in form, but may be trimmed 

 freely.

 along roads, streets and avenues, the 



Planting Time Is Here! 



Last week's rains u-armed old Mother Earth and 

 put the g-rotind in fine condition. Now is the time 

 to select your plants, shrubs and trees so that 

 your grounds will be in beautiful array by summer 

 time.

i.'iciies in <nnnieter. For securing early 

 results the silviT maple has few equals, 

 !)ut it can si:ircely be considered a satis- 

 factory jiermauent tree. Tiie soft, brit- 

 tle wood is easily damaged by high 

 ^vinlls and most old spccinu'us are much 

 (iilaj'idaifil. WicrV cut-l^avcd silver 

 maple is a wonderfully graceful variety 

 of silver maple, with a ])endulous, wee])- 

 iiig liabit. The scarlet or rock maple 

 does brst on low, moist lands and col- 

 ■ rs up in autumn extremely well. 



•A few trees from foreign countries 



bulletin states that tlie distaiues (im- 

 pend on the spee-ies, on the width of 

 the thoroughfare and most of all cm the 

 intentions or exiiectations of the planter 

 in regard to the p)ermanence of the tree- 

 row. Along many streets the trees h.-ive 

 been spaced too closely ffir a jx'rmanent 

 ])lan1ing and no thinning has been 

 done; hence the presence of many t;ill, 

 jiinched, ill-shajte-d maples and elms. 

 I'nless the planter projioses to thin as 

 required, "the largir trees, such as the 

 \\hite elm and red oak," says the bul- 



letin, "should be spaced sixty feet for 

 the former and forty-five to fifty feet 

 for the latter. A space of forty-five feet 

 will suffice for most other oaks. Thi 

 American white ash and pin oak should 

 stand thirty or thirty-five feet apart. 

 The sugar maple and silver maple shoule 

 have a space of forty feet. The ginkgo 

 ought to have a space of thirty feet. 

 Theoretically, the plan of spacing closeh 

 and thinning by taking out alternate 

 trees when they begin to crowd is a 

 most admirable one, but reluctance tv 

 thin them at the right time genoralh 

 defeats the original good intentions of 

 the planter." 



Results of Reckless Pruning. 



Trees generally should be headed 

 back more or less at the time of plant- 

 ing, if the top greatly overbalances the 

 roots. Thereafter, heavy pruning is 

 seldom needed. On this point the bul 

 letin says: "The pruning of shade trees 

 is a subject concerning which informa- 

 tion is often desired, and in a general 

 sense it is safe to say that the matter 

 is usually overdone. During the earlier 

 years of a shade tree's existence but 

 little cutting will be required beyond 

 such as is needed to remove broken or 

 otherwise injured limbs or to preserve 

 a moderately symmetrical, well balanced 

 head. As the specimens grow older and 

 often encroach upon one another or sus- 

 tain injury from storms, heavy cutting 

 will sometimes need to be done. The 

 indiscriminate topping and heading in 

 of trees, particularly such as is in evi- 

 dence along most village streets, can- 

 not be too severely condemned. The 

 heavy, unsightly stubs thus produced 

 afford ojienings through which the germs 

 of decay enter and speedily work havoc 

 to the larger branches and to the trunk. 

 If the trees are properly spaced when 

 ]danted, or are thinned later to avoid 

 overcrowding, little or no i)runing will 

 be needed and the lives of the trees will 

 l>e greatly jtrolonged." 



PLANTING TIME. 



When the warm days arrive it is the 

 right time to remind the home owner 

 if the opportunity spring offers for 

 lieautifying his grounds by plantings 

 ihat will develop under the influence of 

 A]iril showers. Often a suggestion is 

 all tliat is required — the desires of the 

 honu' owner do the rest. The local 

 ]'af)ers give florists and nurserymen 

 this ojiportunity. The illustration on 

 this page shows the form of the sugges- 

 tion to the Chicago jiublic fjiven by the 

 niirs(>ry tirm of .Swain Nelson & Sons 

 <'o., in ;;'--inch double-colunm space in 

 the Chicago Tribune last week. This 

 lirm has a large clientele in that city 

 among the people who decorate their 

 JKune grounds horticulturally.

 Association of Nurserymen, introduced
