Remarks.— Trade is very fair for old Potatos on account 

 of new Tubers being dear, partly owing to the rains in 

 St. Malo and Jersey this week. Stocks of o'd Potatos 

 in London are becoming much smaller. Edward /.

ENQUIRY. 



Rare Iris. — Will anyone who has flowered, or 

 who now has in bud, an Iris which the late Max 

 Leichtlin offered in one of his last lists as an un- 

 named species from Hazara, be so good as to com- 

 municate with me? W. R. Dykes, Charterhouse, 

 Godalming.

Address: Sweet Pea. The secretary of the 

 National Sweet Pea Society is Mr. C. H. Curtis, 

 2, Adelaide Road, Brentford. 



Ai.GM in Ponds : T . L. One part of sulphate 

 of copper in 50,000,000 parts of water is harm- 

 less, and is used in numerous places where 

 the water is primarily intended for drinking. 

 For practical purposes put 2 lbs. of sulphate of 

 copper in large lumps in a coarse sack, which 

 should be dragged in the water at a quick rate 

 at distances of 3 yards apart. If there is much 

 Algae, it should be raked out first, otherwise 

 the quantity killed will cause the water to be 

 offensive for a few days. 



Apple Trees: G. W. J. The injury to your 

 trees is caused by aphides. It will be a diffi- 

 cult matter now to destroy the pests with an 

 insecticide, as the curled leaves will protect 

 them from the spray. Wash the trees next 

 spring with the Bordeaux mixture when the 

 leaves are unfolding. 



Blight : R. L. The injury is caused by aphis. 

 Spray the plants thoroughly with an infusion 

 of Quassia chips. 



Branched Tulips: A. E. M. Every season we 

 receive numbers of branched Tulips. As a rule 

 these stems bear two, three, or four flowers; 

 six flowers are rarer, but in a garden at Chel- 

 sea a Tulip produced seven blooms from a single 

 bulb in 1910. In the Gardeners 9 Chronicle 

 dated May 15, 1909, we ' illustrated some 

 branched Tulips raised by Mons. Bony, 

 Clermont-Ferrand, France, which were ex- 

 hibited at the fortnightly meeting of the R.H.S. 

 on the previous May 4. In these Tulips the 

 branching was stated to be perfectly fixed when 

 the plants were propagated by offsets, and a 

 large proportion of seedlings also produced 

 branched spikes. As a rule, four flowers were 

 borne on each stem, but as many as seven had 

 been produced from a single bulb. These 

 branched Tulips showed considerable variation 

 in colour. 



Celery Fly : S. H. Remedies for this pest con- 

 sist of pinching the maggots which are found 

 on the leaves, and in removing all leaves badly 

 attacked and burning them. ^ Syringe the 

 plants with Quassia extract, which will make 

 the leaves distasteful to the flies, and prevent 

 them from laying their eggs thereon, or scatter 

 lime, &c, on the leaves whilst in a damp con- 

 dition. The plants should be fed liberally and 

 flooded with water or manure water during dry 

 weather. When the crop has been lifted, 

 trench the ground and bury the top spit deeply 

 in order that the flies which are then in the 

 papal stage will be unable to get through the 

 depth of soil. If the attack has been very bad, 

 Apply a little fresh gaa-lime to the soil, fork 



this in to the depth of about 4 inches, and take 

 care not to plant another crop upon this 

 ground until two months have elapsed. 



Dandelions in Lawns: L. M. B. A weed ex- 

 tractor consisting of a hollow steel cylinder 

 should be used to exterminate Dandelions from 

 lawns. The cylinder should be placed over 

 the crown and forced deeply down into the 

 soil, then when it is withdrawn the entire 

 root, with a little of the soil, will be removed. 

 A pinch of salt should then be placed in each 

 hole and filled up with good soil. An iron 

 skewer may also be used, dipped into a bottle 

 of sulphuric acid, forcing the skewer well into 

 the centre of the root. Gloves should be worn 

 when using the acid, so that the hands are 

 protected from the fluid. Another method of 

 getting rid of this weed is to fill an oil-can 

 having a long spout with carbolic acid, and 

 pouring a small quantity of acid on the crown 

 of each plant. 



Gardening Employment in Australia: 

 A. J. D. See reply to Australian in the issue 

 for January 6, p. 15. 



Gooseberries Diseased : Gooseberry. The bush 

 is attacked by Botrytis cinerea; spray with 

 Bordeaux mixture. 



Grapes Damping Off : E. C. In all probability 

 the acid in the bones is injurious. Dust the 

 border with a small amount of quicklime and 

 fork it lightly into the soil. 



Grapes Diseased: J. D., Staffordshire. The 

 vines are attacked with Botrytis cinerea. 

 Spray them with liver of sulphur and keep 

 the house as dry as circumstances will permit. 



Greenhouse : A. -R. The law as to the right to 

 remove a greenhouse is very vague and some- 

 what complicated, but you will find it fully 

 dealt with in Gard. Chron., September 29, 

 1906, p. 221. In the circumstances which you 

 have described, it is impossible to advise you 

 that you would be quite safe in removing even 

 the upper part of the structure, if the land- 

 lord chose to bring an action against you. ^ It is 

 a matter that needs a definite decision in the 

 Law Courts. 



Grubs in Young Apple Trees: A. C. D. The 



grub is that of the leopard moth. Your best 

 plan will be to find out the holes in which 

 caterpillars are boring, and pass a piece of wire 

 into them for the purpose of killing the cater- 

 pillars, or inject into the holes paraffin 

 : emulsion. 



Mealy Bug : E. C. This pest cannot be eradi- 

 cated when the plants are in active growth. 

 Add one liquid ounce of carbolic acid to one 

 gallon of lime water.

Pictorial Seed Pockets : Enquirer. These are 

 manufactured by Messrs. Blake & McKenzie, 

 Printers, Islington, Liverpool. 



Preserving Green Peas: A. L. A method of 

 bottling Green Peas is to shell the Peas, put 

 them into dry, wide-mouthed bottles, and shake 

 them together so that they may lie in as little 

 space as possible; cork the bottles^ closely, and 

 seal the corks. Bury the bottles in the driest 

 part of the garden, and take them up as they 

 are wanted. They ought to keep good for some 

 months. Another recipe is: Choose Peas 

 which are large and fully grown, though not 

 old. Put them into perfectly dry, wide- 

 mouthed bottles, shake them down, cork 

 securely, and cover the corks with bladder. 

 Tie a wisp of hay round the lower part of 

 the bottles to prevent their knocking against 

 each other, put them side by side in 

 a large saucepan, and all water up to the 

 necks of bottles. Place the saucepan on the fire, 

 and let the bottles remain standing in the water 

 for two hours after it has reached boiling point, 

 then take the saucepan off, but do not remove 

 the bottles until the water is cold. Seal the 

 corks, and store in a cool, dry place. 



Propagation of Trees from Cuttings: C. G. 

 db Co. The mode of propagation of forest and 

 ornamental trees varies considerably ; the num- 

 ber that can be increased from cuttings is some- 

 what limited, and include Catalpa, Cotoneaster, 

 Corylus (Hazel), Elaeagnus, Hippophae, Ilex 

 (Holly), Mulberry, Laurel, Poplar, Plane, 

 Robinia (root-cuttings only), and Willow. Of 

 Conifers, Cephalotaxus, Cupressus, Crypto- 

 meria, Juniperus, Taxus, and Thuya may be 

 increased by means of cuttings, but they 

 require a special treatment, and a knowledge 

 of the proper time to insert the cuttings to 

 ensure success. 



Record Strawberries : F. W. C. Reference to 



our record book shows that a fruit of the 

 variety Keen's Seedling, which was 7£ inches 

 round, and weighed 1£ ounce, held the record, 

 so this must now give place to your 10 fruits 

 which weighed just over 1 lb. 



Spraying Rose Trees : L. M. S. We do not 

 think the rather strong solution of Cylhn soft 

 soap was altogether the cause of your partial 

 failure. All the more so because such tender 

 foliaged varieties as Joseph Hill and Marquis 

 de Sinety were uninjured. At the date men- 

 tioned the weather was very chilly, and this, 

 in conjunction with insect pests and mildew, 

 would cause the burnt appearance. The ^^ 

 is not likely to be permanent, and will not 

 affect the future growth. Remove the leaves 

 if they do not fall naturally. A frequent use 

 of weak solutions is safer than strong doses ana 

 generally as -effective. In future use only one 

 ounce of Cyllin soft soap to each gallon of water 

 when spraying tender foliage. 



Trop-eoltjm and Yew Hedge: Anxious. Y° u 

 need entertain no fears of the roots of Tropaeo- 

 lum speciosum damaging the roots of the Yews* 

 but if the growths of the climber are at au 

 luxurious, they will very likely kill portions 

 of the hedge. 



Vine Leaves : Constant Reader. The warty ap- 

 pearance of the leaves (known as warty disease/ 

 is due to an excess of moisture in the atmo- 

 sphere and surroundings. Afford plenty o 

 ventilation, and keep the conditions drier. 



Vine Leaves Injured: E. C, Por ^f m k L 

 The leaves are merely scorched. Ventilate tne 

 house as early in the day as possible. 



Violas Diseased: A. B. The injury is caused 

 by a fungus Puccinia violas. Spray the plan* 

 with liver of sulphur. The soil will also be in- 

 fected, and should not be used for f°* l *° 

 Violas again unless it is sterilised by heating.
