ipera- 



CORRESPONDENTS, 



Editorial Communications should be addreeeed to the 

 Editor of the Gardeners' Magazine, 148. and 149, 

 Aldersgate Street, E.G. 



Secretaries of horticultural societies are incited to 

 send early notification of forthcoming exhibitions 

 and meetings, and are requested to advise Ufi con- 

 cerning changes of dates. 



Specimene of plants, flowers, and fruits for naming 

 or opinion should be sent to the Editor of the 

 GrARDENERs' MAGAZINE, " Endfileigh," Prior Park, 

 Kew, Surrey, and as early in the week as possible. 

 AU parcek must be sufficiently prepaid. 



The Editor will be glad to receive photographs of 

 gardens, plants, flowers, trees, fruits, etc., for 

 reproduction in the Gardeners' Magazine. He will 

 also be greatly obliged by correspondents sending 

 early intimation of interesting local events relating 

 to horticulture. In sending newspapers containing 

 matter to which they wish to draw attention cor- 

 respondents are requested to distinctly mark the 

 paragraph. 



GALLS OX RHODODENDRON LEAVES. 



■ 



— L. F., Newark: Please tell me the cause 



of the galls on enclosed rhododendron leaves, 

 and cure, if possible. — The galls are due to 



the presence of a fungus named Exobasidium 

 rhododendri, and all infested leaves should 

 be at once removed and burned, so that they 

 do not produce their spore-bearing organs 

 and spread the disease. 



DISEASjED tomatoes.— B. S., Devon: 

 A number of my tomatoes have black patches 

 on the fruits (specimens enclosed)^ and I 

 shall be glad if you will tell me how to stop 

 the trouble. — The black patches are ample 

 evidence of Black Rot (Ma^rosporium 

 tomato), a disease that is fairly common in 

 tomatoes. A moist, stagnant atmosphere 

 always encourages fungus troubles, hence 

 great care should be taken with watering 

 and ventilation. It is said that the black 

 rot disease is a wound parasite, and can only 

 find entrance by means of wounds or cracks 

 in the fruit. This, again, points to the need 

 of more care than is frequently exercised in 

 tying and training the plants. Remove and 

 burn all affected fruits, and spray the plants 

 with a potassium sulphide solution (loz. to 

 2i gallons of watey) at intervals of' about 

 a week. 



URSINEA PULCHRA.— L. C, Seaford : 

 During the winter we received some seeds 

 from South Africa, and were told that they 

 came from a very pretty yellow-flowered an- 

 nual. We treated the seeds a-s for half- 

 hardy annuals, and have now a considerable 

 batch just in bloom. I enclose a few blooms, 

 which are very showy, the blackish zone set- 

 ting off the yellow colouring finely. There 

 is something familiar about the plants^ but 

 no one here can tel] me the name. Perhaps 

 you will help me. — The flowers are those of 

 Ursinea pulchra, a South African species 

 that is occasionally catalogued as Spheno- 

 gyne speciosa. It is a showy annual, best 

 treated as half-hardy, and it is one that 

 suggests great possibilities in the hands of 

 some clever and patient grower. There is a 

 form with wholly yellow flowers. Careful 

 selection should make sturdier plants, and 

 give variety in colour. 



SEDUM SIEBOLDL— D. E. P., Chelms- 

 ford : I enclose a small piece of a plant w^hich 

 I understand is Sedum Sieboldi. I have seen 

 it cultivated as a pot plant, and should be 

 glad if you will kindly give me some par- 

 ticulars concernino- its management. — Sedum 

 Sieboldi is a trailing Japanese species that 

 is not quite hardy in all parts of the coun- 

 try, but is a capital greenhouse plant, and 

 one especially suitable for cultivation in hang- 

 ing baskets, or in pots for the decoration of 

 bench margins. The specimen sent is S. 

 Sieboldi variegatum, and this is more effec- 

 tive than the type, as it has a bright creamy 

 blotch on each leaf, whereas in the type the 

 leaves are wholly blue-green. S. Sieboldi 

 has pink flowers,^ each petal with a g-reen 

 spot, and the^e appear about August. Early 

 spring is a good time to divide and repot 

 old plants; the soil should be sound loam, 

 with some old mortar rubbish and sand. An 

 ordinary greenhouse will suit the plant very 

 well at such season, but before potting and 



lure oi 4U aegrees will suttice it a light posi- 

 tion is provided. In some districts Sedum 

 Sieboldi and its variegated form are largely 

 grown by cottagers, who suspend their plants 

 inside the front-room window throughout the 

 winter3 and hang them over the doorway or 

 window, outside, during the summer. 



LARGEST-BERRIED AYHITE GRAPE.— 

 M. M.,^ Worthing: Will you please tell me 

 w^hich is the largest-berried white grape : 

 Duke of Buccleuch is regarded as the largest- 

 berried white grape in cultivation. When 

 well grown the berries are of wonderful size, 

 and. as they seldom have more than two 

 seeds, their useful content is large. This 

 variety was raised by Mr. Wm. Thomson, 

 when at Dalkeith, and gained a first-class 

 ceii:ificate from the Roval Horticultural 

 Society in 1872. 



HARDY FLOWER BORDER. _ A. S., 



Chelsfield : What would you suggest to make 

 an effective border 5ft. wide and 20ft. long, 

 backed by a creeper-covered wall ? I liave 

 been using antirrhinums, mallows, agera- 

 tums, and stocks. The border has a box 

 edging. — In the early autumn clear the bor- 

 der, and trencb the ground, working in 

 plenty of well-decayed manure. As soon as 

 the soil has settled plant a selection of 

 Michaelmas daisies, delphiniums, and helian- 

 tliusee tow^ards the back, with erigerons, 

 pyrethrums, varieties of Chrysanthemum 

 maximum, heleniums, rudbeckias, achillea^, 

 geums, ete., along the centre and towards 

 the front. Leave room for a few antirrhi- 

 Ls, and early -flowering chrysanthemums, 

 coreopsis, and gaillardias, to be planted in 

 the spring. Two or three pillar roses might 

 be added; while, in flowing groups along 

 the front, pinks and violas should be pro- 

 vided, as these flower so freely. This is a 

 mere outline of what vou could do. Bulbs 

 should be planted for spring effects among 

 the other subjects. We suggest tbat you 

 pay special attention to our numerous 

 articles on hardy plants; look round gardens 

 and flower shows in your neighbourhood, and 

 make notes of plants that appeal to you, and 

 then, later on, write us again, and we will 

 be pleased to give vou all the help we can.

GARDENING ENGAGEMENT, 



Mr. E. Harriss, fruit foreman a1 the Roval 

 Gardens, Windsor, has been appointed head 

 gardener to Lady Wantage, Ixickinge Park, 

 Wantage. Borks, in succession to the late 

 Mr. W. Fvfe. 



— Witb the im- 



provement in the flowers of this now well- 

 known and popular primula, it seems — at 

 least, as far as my limited experience goe^ 

 that the leaves are less poisonous than was 

 at one time the case; at all events, we do not 

 hear as many complaints as w^e formerly 

 used to. Personally, however much I 

 Iiandled them, I was never affected thereby.
