 Gardens, Horticultural Society, at Chiswick Gardens, and the Royal South 

 London, at the Surrey Zoological Gardens, during May, June, and July, &c. 

 They are expected to far exceed any former ones in the quantity and quality of 

 specimens.

FLORICULTURAL CALENDAR FOR APRIL. 



Greenhouse.— During the early part of May a few frosty nights generally 

 occur ; in consequence of which, it is advisable not to take out the general stock 

 of plants before the middle of the month, or even, in cold situations, before the 

 25th. Whilst the plants, however, remain in the greenhouse, let them have all 

 the air that can be given during the day, and at nights if no appearance of frost. 

 Particular attention will now be required to afford an ample supply of water to 

 free growing kinds of plants. Frequently syringe them over the tops at evening 

 just before sun-set. If any of the plants be attacked with greenfly, or any other 

 similar insects, apply a sprinkling of tobacco-water, diluted with water, by adding 

 to one quart of the liquid five of water; in applying which to the plants, syringe 

 them at the under as well as upper surface of the leaves ; a repetition will rarely 

 be required. This mode of destroying the insects is far preferable to fumigation, 

 no injury being sustained by it, even if applied in a pure state. The liquid cau 

 be obtained of tobacconists at lOrf. or 1«. per gallon. It is a good time for 

 increasing plants by cuttings, striking in moist heat. Greenhouse Annuals — as 

 Salpiglossises, Globe Amaianthuses, Balsams, Coxcoml s, &c. — should be en- 

 couraged by a little warmth, and shifted into larger pots early in the month ; so 

 that the plants may make a show, to succeed the removal of the general collec- 

 tion of greenhouse plants. Cuttings or suckers of Chrysanthemums should now 

 be taken off and potted in rough, rich compost, having a free drainage, if net 

 done before. Achimenes coccinea, longiflora, rosea, &c, plants, should be potted 

 singly into a light rich soil, and be forwarded in the stove, and repotted as they 

 advance in growth, not too much at a time, but as root room appears necessary. 

 Lobelias for the greenhouse should be similarly treated, as to putting, %c. 



Flower Garden. — Continue to protect beds of Hyacinths, Tulips, &c. Car- 

 nations in pots should be encouraged by manure water, &c, in order to grow 

 them vigorously; care in tying them will be requiied. By the middle of the 

 month half hardy annuals — as China Asters, Marigolds, &c. — may be planted 

 out in the open borders. Some of the best kinds may be potted, as done to the 

 more tender sorts. Many kinds of greenhouse plants — as Petunias, Salpiglos- 

 sises Salvias, Fuchsias, Heliotropes, &c. — should now be planted out in the open 

 border. Dahlias that have been forwarded in pots, frames, &c, may be planted 

 out towards the end of the month. Seedlings may be pricked out, in a warm 

 situation, having a t deep. fresh, rich soil. When Stocks, Mignonette, China 

 Asteis, &c. are wished to bloom late in the year, seeds may now be sown, either 

 under a frame or on a warm border. Slips of double Wallflowers should now be 

 put in under a hand-glass. Seeds of biennials — as Sweet Williams, Scabious, 



Campions, &c. should now be sown. Tuberoses, for late flowering, should now 



be repotted or put into warm borders. Offsets of Campanula pyramidalis should 

 be repotted in rich soil, and placed in the greenhouse. Repotting must be con- 

 tinued till they cease to grow ; by this means the plants will reach eight feet 

 high and be very branching. Cuttings of Geraniums, Salvias, Heliotropes 

 which have been struck for planting into open beds, and not potted off, should 

 be immediately done, so as to be well prepared fur turning out by the 20th. 

 Auriculas and Polyanthuses will require shading, but admit all possible air, or 

 the flower stems will be very weakly. Protect from rain. Ranunculuses and 

 Anemones shade, water, &c. — See Articles in former Numbers on each.
