Many good commercial fertilizers are almost or quite odorless—ammoniated bone meal, for example. There is also a fertilizer in lozenge form which is scentless and wonderfully effective. Dissolve a lozenge in boiling water, let stand all night, then stir well and apply. Give a teacup—the same as of liquid manure—to a ten-inch pot, a tablespoonful to a four-inch one, and half that to a thumb pot. A quart will be none too much for a three-foot window box filled with soft-stemmed plants. They demand more than woody plants. Over-fertilizing is bad—it turns leaves yellow and scants bloom. Plants suffer indigestion the same as people. The remedy for it is to set them in a sink or on a grating and pour hot (not boiling) water through the pot until it runs out clear. =Insects and Insecticides=: Insects are the pest of house plants. The worst of them are plant lice, mealy bugs, white and black flies, red spider, and the various scales. All are fought with pretty much the same weapons—namely, soap and water, smoke, and eternal vigilance. Greenhouses and hothouses are almost universally infested. Hence every new plant must be suspected. Do not set it among other plants clean and thrifty for at least a fortnight, and then only after a thorough bath. A plant badly infested had better be thrown away, and quickly. Flies white and black are hardest to fight; they fly away at a touch on the pot. Set the infested plant apart, with a stick standing higher than itself fast in earth, throw a thin cloth over, letting it reach the ground all around, then slip under it a lighted smudge, and set over cloth and plant either a box or a barrel, with paper pasted over the cracks. Let stand two hours, then plunge in a tepid bath, keeping on the cloth until well under water. This to hold in any flies left living. Splash well, drain, and while damp dust with either insect powder or finely crumbled tobacco, putting it on both sides of the leaves. For plant lice spray thickly with strong tobacco water, leave an hour, then bathe, and dust with more tobacco. A little flowers of sulphur mixed in makes the treatment more effectual. Bathe in suds (carbolic soap, if possible) next day, and follow with a clear tepid shower.
