Although one will not know exactly what one is getting with a seedling rootstock — every single seed is a genetically different individual — hardiness , anchorage and adaptability to different soil types are generally excellent . Secure the netting so there is no place for the birds to enter . However , evidence indicates that some pear varieties may be self-fruitful under some conditions , and you might be able to get a small amount of fruit with only one tree . Plants and some varieties vary in resistance . Fertilize the soil every month during late spring and summer , but mix your fertilizer half-strength . In order to be effective , they must be applied at the first sign of disease and repeated every 7-10 days . Some outdoor plants such as vegetables in the tomato family and the cabbage family can also be affected . Other techniques are capable of generating images of the Earth 's surface and topographic data , but no other technique provides high-spatial-resolution maps of earthquake deformation . Reapply the mulch every few years as it breaks down . There are currently no fungicides available to homeowners for white mold control . Some of the fruitlets will drop in mid-June , but the tree may be left with more fruit than is optimal for fruit quality development . For now , however , sanitation ( promptly removing and destroying fallen fruit and leaves ) , cultural practices designed to promote optimum tree health , and perhaps occasional physical or chemical intervention are all that is normally needed to obtain a satisfying crop in most years . This information is supplied with the understanding that no discrimination is intended and no endorsement is implied . Pruning the trunk back in this way is intended to induce branching that will result in scaffold branch options the following year . If you must prune during the growing season , to do it on a day when no rain is forecast and the air is dry . At that point , caterpillars have grown to about 1 to 2 inches in length . Instructions for taking a soil sample , and containers for sending a sample can be obtained through your county extension office . For a nonbearing fruit tree , prune to develop a basic structural framework that will support future crops . Aster yellows is a plant disease which affects a wide range of plants including flowers , vegetables , and weeds . Excessive pruning should be avoided because it greatly reduces the crop for that year . Iris leaf spot is a common disease caused by the fungus , Mycosphaerella macrospora ( formerly Didymellina macrospora ) . Control efforts with fungicides require reapplication every 7 to 14 days . To shorten the time required to estimate the deformation rate , precise repeated measurements are required ; in some cases , where time dependence of strain accumulation is suspected , very frequent or even continuous measurements are needed . By this we mean that , within a given pixel , the position of radar scatterers has not changed to any significant degree , but the ensemble of scatterers ( i.e ., the entire ground surface within that pixel , as well as some adjacent ones ) has moved up , down , or sideways in some correlated fashion .
