Attention to the Roses 



Feed freely with liquid manure; if large exhibition blooms are wanted, 

 rub off all but the terminal bud. One sure way to get control of 

 rose bugs is by hand picking into a can of kerosene. Spraying 

 with arsenate of lead, 5 pounds to 50 gallons of water, repeatedly, 

 is an old remedy, not very effectual. Melrosine is a new prepara- 

 tion recommended for its effectiveness. 



Gladiolus for late fall cutting to be planted at 2-week intervals. 



Dahlias to be planted during the month; put out stakes before setting 

 out tubers or plants. When growth has started, reduce shoots to 

 one, allowing side branches to develop one foot above the ground. 



Propagating for the Hardy Border 



Many herbaceous and alpine plants may be propagated after flowering 

 by cuttings or offsets. The Creeping Phloxes, Cerastiums, 

 Sedums, Aubretias, Arenaria, and Iberis, are among those that 

 may be increased at this time. Use a frame containing sandy soil 

 and which can be shaded from hot sun. Stock may also be in- 

 creased by sowing seeds at this time. Such subjects as Delphin- 

 iums, Lupins, Foxgloves, Canterbury-bells, Sweet Williams, 

 Aquilegias, Oenotheras, Heucheras, and other perennials, will 

 make plants of sufficient size to plant into permanent quarters in 

 the fall if sown now. A seed bed in the open ground will meet the 

 requirements of these plants at this time, but as the frames 

 are emptied of other stock they may be utilized. Shade is es- 

 sential until germination takes place. 



Fruit Garden 



Thin the "set" of Apples, Pears, Peaches. Much finer fruit will 

 result, with superior flavor, and the aggregate weight at least 

 equal. True also of Grapes. 



Crops of Gooseberries, Currants, Strawberries depend to a large extent 

 upon the amount of moisture maintained about the roots. Use 

 grass clippings and other mulching material. 



Summer pruning (pinching out the tip of the young growth) will 

 keep the young fruit trees in better shape and induce fruitfulness. 



Retard the Currant crop and gather fresh fruit in August by covering 

 bushes with muslin or burlap before fruit ripens. Watch Black- 

 berries and Dewberries for orange rust, burning affected bushes as 

 soon as discovered. 



To feed fruit trees scatter stable manure over the ground as far as the 

 spread of the branches; or use 4 to 5 pounds of phosphoric acid 

 for each large tree, and, after raking it in, mulch the surface with 

 the weeds and other refuse taken from the garden. Trees with 

 rank, vigorous growth and little fruit do not need manure; those 

 with small, undersized fruit and little or no annual growth will 

 be benefited. 



The Greenhouse Plants for Next Winter 



This is preparatory season for next winter's supply of cut flowers, pot 

 plants, etc. A general clean-up is essential. Discard old plants, 

 renew soil and generally overhaul. As many subjects as possible 

 that are to be carried over should be accommodated in frames. 

 Adiantums (Croweanum, cuneatum, and gracillimum); Pteris; 

 Cyrtomiums; Polypodiums; Davallias, and Nephrolepis; Cycla- 

 men; Primulas, and other flowering plants are amenable to frame 

 culture at this time. 



Antirrhinum seedlings intended for an early winter crop should now be 

 large enough to prick off. Give a fairly rich soil and plenty of 

 room. 



Still time to root a batch of the exhibition Chrysanthemums. They 

 will make fine dwarf plants in six-inch pots. Early rooted plants 

 to be potted on as fast as they fill the pots with roots, until they 

 are in their flowering pots. Plants for bench culture to be planted 

 into flowering quarters now. 



Sow seeds of Primula malacoides and its varieties, also Cineraria; give 

 the latter every protection from heat and grow as cool as conditions 

 will allow. 



Celosia sown now will provide blooming plants by the end of August. 

 Plants on hand to be repotted to larger pots. 



Gloxinias to be well shaded and grown cool. Fumigate for thrips. 



Begonias of the Lorraine type require shade and careful watering. 

 Keep near the glass to secure stickiness. 



Gardenias require frequent and thorough syringings to keep them free 

 from mealy bug. Keep the atmosphere moist by frequent damp- 

 ing down of the paths and walls. 



Cyclamen to be potted on as required, using a light but rich compost. 

 Well-rotted cow manure and bonemeal are good sources of food for 

 these subjects. 



Poinsettias to be potted up for winter flowering. Azaleas are worth all 

 the care that can be bestowed upon them now; plunge out of doors 

 after they have flowered with others of their kind to ripen. 



Roses to be planted with all possible speed; avoid overwatering; 

 cultivate regularly to keep weeds down. Fumigate if green fly 

 troubles. 



Carnations in the benches may be discarded. Continue cultivating the 

 young stock outdoors and keep the leading shoots topped as they 

 begin to make headway. If your soil is such that you have to 

 resort to watering the plants in the field this month, reduce the 

 supply toward the middle of the period so that the plants will not 

 be too soft for benching early next month. 



Plunge Amaryllis up to the rims of the pots in frames and keep the 

 sashes elevated all the time. They are making their growth now 

 for next season's flowering and, in addition to an abundance of 

 water, a top-dressing of commercial preparation of fertilizer or 

 applications of liquid manure will be of benefit to them. Seedlings 

 to be kept growing along, having no rest until they have flowered. 



Pelargoniums for propagating to have the water supply reduced so the 

 wood will ripen. 



Decorative plants are now at the height of their growing season: see 

 that growth does not become too soft. Shade only enough to 

 break direct rays of the sun and give abundant ventilation on all 

 favorable occasions. Old plants of advanced age and size should 

 be repotted if necessary. 



Christmas Peppers and Bouvardias planted outdoors to be pinched at 

 frequent intervals to induce bushiness. 



Calanthes now growing freely will take water liberally; do not feed until 

 the pots have plenty of roots in them. Syringe overhead on 

 favorable days, but do not leave the foliage wet overnight. Cal- 

 anthes like a brisk, moist heat. 



Pot fruit trees need room. Nets underneath will catch any fruits that 

 may fall off. Young Peach trees trained on trellises, making first 

 year's wood for the forming of the main branches of the trees for 

 years to come, to have the young wood laid in right or they will 

 never look as they should. As the last fruit is taken from the 

 early peach house give a thorough syringing to dislodge any red 

 spider. Give water if the border is on the dry side, and a little 

 feeding will help the plants to build up flower buds for next season. 

 Keep ventilators wide open.
