Spring brings soft ground, and horse's hoofs are heavy. You 

 either wait, and the grass gets too long, or you put such holes in 

 the ground as a season's rolling can hardly level.

r-Farr's Specialties for Early Spring Planting— i 



Year after year the garden increases in charm and value as the shrubs and 

 plants increase in size and blooming power. Early spring is a desirable time 

 for setting most plants, and in my collection at Wyomissing may be found 

 specimens that are suitable for every phase of gardening. A few are here 

 noted — to list all would be impossible: 



Japanese and Asiatic Shrubs — Berberis, Flowering Cherries, Enkian- 

 thus, Cotoneasters, Corylopsis and others. 



French Lilacs, Philadelphia and Deutzias — a complete collection of 

 Lemoine's new creations. 



Rare Specimen Evergreens for the formal garden, lawn groups and rock 

 gardens. 



Hardy Asters, Phloxes Delphiniums, Chrysanthemums and other peren- 

 nials for spring. 



An Emergency Edition of Farr's Hardy Plant Specialties (issued because 

 of the great demand for the sixth edition) will be sent to those who request 

 a copy.

of iron sulphate to a gallon of water seems to give 

 the best results. The solution must be applied 

 at least three times, at intervals of about two 

 weeks. In Colorado the most effective results 

 were obtained in late summer. It is important 

 that the spray be applied in the form of a fine 

 mist driven forcibly into the crowns of the plants. 

 Cloudy, damp weather is particularly favorable 

 if the application is not followed by rain within 

 twenty-four hours. 



This material is damaging to most metals, 

 therefore it should be used in a spray pump hav- 

 ing brass fittings, and never put into any iron, 

 galvanized iron, or tin vessels. Moreover, all 

 utensils must be thoroughly rinsed with water 

 after the work has been completed, and the mov- 

 able parts of the pump kept well oiled. It is 

 likely to cause a rusty stain if it touches walks and 

 curbings, so should be used carefully, or some sort 

 of protecting material laid down. The weak 

 solution does no serious injury to the grass, 

 although it may seem to affect it at first That 

 part of the lawn sprayed however will eventually 

 take on a greener hue than before — but it is 

 deemed advisable to pay particular attention to 

 watering and mowing the lawn, in order to en- 

 courage the growth of the grass. And White 

 Clover, if present, will probably be killed out. 



HOW TO MAKE A "CROSS" 



THE essential point in crossing is to prevent 

 the stigma of the chosen seed-parent from 

 being pollinated by any flower except the one 

 desired as a pollen parent. In order to accom- 

 plish this: (t) remove all flowers that have opened 

 and shed any pollen; (2) select several buds that 

 look as if they would open in a day or two, and 

 gently pulling their segments apart hold the bud 

 open with the fingers of the left hand while the 

 immature anthers are removed by the fingers or 

 by means of tweezers. Be sure that you take 

 out all (six in Lilium). 



Cover the bud with a paper bag, leaving it 

 for two or three days. Then remove it and ex- 

 amine the stigma, the knob-like end of the pistil. 

 If it be viscid and glistening in the sun, it is ready 

 for the pollen of the chosen species. Cover it 

 well with pollen and replace the bag, keeping it 

 on until the stigma withers and further danger 

 of foreign pollination is past. 



The paper bag has certain disadvantages. 

 Damage to some of the flowers in removing or 

 replacing the bags, is certain; and on a warm day, 

 the atmosphere inside the bag will become hot 

 and steamy and may prevent seed formation. 

 On a large scale omit the bags entirely, but take 

 extreme pains to keep all the buds on the patch 

 emasculated. This method is practically as ex- 

 act as the former method if the different species 

 are planted in isolated groups in different parts 

 of the garden. Its great drawback lies in the 

 necessity for the rigid surveillance of every bud. 



Give each cross some distinguishing mark, or 

 write the names of the parents on a label and 

 fasten it to the flower stalk. — H. E. Gilkey. 



[Though the method of procedure here out- 

 lined refers specifically to work on Lilium, still 

 the same principles applyin general to all ordinary 

 flowering plants. The smaller the parts or the 

 more intricate the work the more difficult is the 

 handling, necessitating practise and patience.]
