Plants that are not making satisfactory growth, through feeble root action, may often be in- vigorated by this treatment, which is especially useful in trees recently transplanted or weakened by overbearing. (b) By suppressing reproduction.—• When growth is desired, it is often advisable to prevent the development of flowers. Newly planted straw- berry, raspberry and blackberry plants usually make better growth the first season if the flower-buds are picked off. The removal of flowers in the potato plant tends to stimulate the growth of tubers, es- pecially in varieties that form seed. The removal of flower-buds from cuttings in the propagating bed en- courages the formation of roots. Topping tobacco and rhubarb plants (416) causes the leaves to grow larger, and in onion plants stimulates growth of the bulbs. De-tasseling corn encourages growth of the ears (416). Thinning fruit on plants that incline to overbear causes the remaining fruits to grow larger (159, 416). 428. Pruning for flowers or fruit. — Since checking growth tends to stimulate the formation of flower-buds (134), we encourage flowering in plants that incline to luxuriant growth, by pruning, which tends to check vigor. This may be accomplished :.
