Now select 4 or 5 scaffold branches from those that remain , pruning out any “ duplicate ” branches that are growing just above or just below scaffolds . Powdery mildew can be a serious foliar disease in some years and some locations ; for control of powder mildew or another specific insect or disease pest , contact your county extension office . Some grasses are semi-evergreen and hold their color into the winter , such as blue oat grass . Fertilize the soil every month during late spring and summer , but mix your fertilizer half-strength . Some research indicates that the use of oat straw mulch may reduce leafhopper numbers . Remove any dead leaves , and soak infected plants in hot water ( 120-140 degrees ) for up to 10 minutes ( you may wish to divide plants up and soak 4 , 7 and 10 minute intervals ) . Control efforts with fungicides require reapplication every 7 to 14 days . Always follow label directions when using any pesticide . Knowledge of antenna baseline length B and orientation implies accurate knowledge of the orbital parameters of the spacecraft and spacecraft orientation during each image acquisition . Third , remove and destroy infected leaves , and remove all dried leaves and stems during fall clean up . CAUTION : Read all label directions very carefully before purchasing and again before using an insecticide . Some apple varieties produce strongly vertical growth and need more training ; others tend to produce branches that are naturally well-angled . Reapply the mulch every few years as it breaks down . In order to be effective , they must be applied at the first sign of disease and repeated every 7-10 days . 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 . As discussed in more detail below , to measure surface displacement to this precision requires a relatively accurate a priori estimate of topography in the region and information on the position and orientation of the antennas during each image acquisition . Remove all plant debris in the fall to reduce the amount of inoculum the following spring . The measured phase at each point in each of the two radar images is equal to the sum of a propagation part , proportional to the round-trip distance , and a scattering part due to the interaction of the wave with the ground . If you have purchased a smaller tree with little or no branching , remove any branches , and prune the trunk to about 30 to 40 inches above the ground . The roots are bitter , stunted and deformed , with tiny hair-like roots growing all over the main root . 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 . Then dig a trench out from the base of each plant . Aim for one fruit per cluster , or for truly optimal fruit quality , about eight inches between fruits on any branch .
