It is perfectly feasible to plant sour-stock seedlings and to graft them afterward to whatever variety of oranges you desire to grow, but it is undoubtedly better to pay a pretty good price for budded trees of the kind you desire rather than incur the delay and the irregular growth of young trees budded or grafted in the field. There is also danger of an irregular stand from accidental injuries to new growth started in the field without the protection which it finds in the nursery row. Budding Oranges. How late in the fall can budding of orange trees be done - plants that are two years old - and what advantage, if any, is late budding? What shall I do with some old trees that were budded about two months ago and are still green but not sprouted yet? The budding was done on young shoots. Late budding of the orange can be done as late as the bark will slip well; usually, however, not quite so late as this. Such buds are preferred because in the experience of most people they make stronger growth than those put in in the spring. Such buds are not expected to grow until the lowest temperatures of the winter are over. The buds which you speak of as green but still dormant are doing just what they ought to do. They will start when they get ready. Under-pruning of Orange Trees. My Washington Navels have a very heavy crop on the lower limbs, as is usual. These branches are so low down that many of the oranges lie on the ground, and it takes a good deal of time to prop them up so that they will not touch the ground. What would be the result of pruning off these low branches, after the fruit is off? Will the same amount of fruit be produced by the fruit growing on the limbs higher up? Certainly, raise the branches of the orange trees by removing the lowest branches or parts of branches which reach to the ground. A little later others will sag down and this under-pruning will have to be continuous. It would be better to do this than to undertake any radical removal of the lower branches. The progressive removal as becomes necessary will not appreciably reduce the fruiting and will be in many ways desirable. Keeping Citrus Trees Low. My tangerines last fall shot up like lemon trees - a dozen to twenty shoots two or three feet high. The trees are eight years old and are loaded with bloom and some of the shoots have buds and bloom clear to the top. Some shoots have no bloom. What should I do with these shoots? Cut them back like lemons or let them remain? You must shorten the shoots if you desire to have a low tree. This will cause their branching and it will be necessary, therefore, to remove some of the shoots entirely, either now or later, in order that the tree will not become too compact. Dying Back of Fruit Trees. I have a few orange and lemon trees that are starting to die. One tree has died on the top. What kind of spray shall I use?
