Can Tree Roots Break Through Concrete' title='Can Tree Roots Break Through Concrete' />These requirements basically are. I. Variety The rhododendron or azalea must be suitable for the climate where it is planted. Some varieties are too tender for harsh winters, too tender for very hot weather or full sun, too sensitive to droughts or wet conditions. For specific problems, visit Cold Resistance, Sun Shade, and Heat Tolerance. Select the variety for the location. Different varieties grow different heights. Some are tall, over 6, and some are dwarf, barely 1. Unfortunately, most rhododendrons never stop getting taller, but their height is quoted for plants that are 1. But if you choose plants that are the right size to begin with, they are relatively maintenance free. The American Rhododendron Society website has good charts for rhododendrons and azaleas giving the hardiness and height. Other very useful charts on the ARS website are the Proven Performer Lists that list the favorite rhododendron and azaleas plants for different parts of the US and Canada.

Can Tree Roots Break Through Concrete' title='Can Tree Roots Break Through Concrete' />The American Rhododendron Society has also applied quality ratings to most rhododendrons and azaleas that are commercially available. The scales run from 1 to 5 for the flower and also for the plant, where 5 is best for the flower and the plant. For example 43 has a rating of 4 for the flower and 3 for the plant. Many nurseries such as Greer Gardens publish these rating for all of their plants. Greer Gardens website has the most comprehensive list of descriptions and photos of rhododendrons and azaleas that are available in the trade. II. Soil Drainage Rhododendrons and azaleas thrive in moist, well drained soils high in organic matter. Wireless Led Seminar Pdf there. Rhododendrons and azaleas have shallow fine silk like roots. These roots do not tolerate water saturated soil conditions but do require moist soils. Poor drainage and wet soils are problems often associated with heavy clay and compacted soil. To test drainage, dig a hole about 1. Then after it drains, fill it with water again and see how long it takes to drain. If the hole drains within an hour you have good drainage. If the water has not drained out of the hole within four hours, the soil is poorly drained and you must correct the drainage problem before planting. Planting in raised beds is the best solution in heavy soils. Raised beds are built on top of the native soil to a depth of 1. Raised beds may require watering during the summer as they dry out faster. Moist well drained soil is a must for most varieties. This sounds difficult, but it means to not let the soil dry out completely but dont get it too wet. Before placing the tree in the hole, break up the tightly wound rootball and carefully fan out the roots. Dont pull too hard or the roots will break. Polyethylene Under Concrete Slabs Does the poly vapor barrier belong above the rigid foam or below the rigid foam Sewer repair and sewer replacement Tree roots in sewer lines routinely result in expensive repairs. How to avoid a sewer repair or replacement. Thoroughly water if necessary and then let it become almost dry. Most gardeners do this by planting in a well drained area and mulching to hold the soil moisture in. Candy Cnl 145 Manual. Then, watering is seldom necessary except during long dry periods. Conditions that provide good drainage usually provide good aeration. However, aeration is sufficiently important that it must be emphasized. The soil must be aerated since the bacteria that make nutrients available to the roots require oxygen. For specific problems, visit Drainage, Aeration, Soil Mix, Watering. III. Acid Soil Rhododendrons and azaleas prefer acidic soils having a p. H between 4. 5 to 6. Rhododendrons and azaleas will let you know if the p. H is not correct. If the leaves turn yellow between green veins then you most likely have a p. H problem.  If this occurs, a soil test is suggested for exact recommendations on adding a soil amendment to the soil in order to adjust the p. H.   Materials commonly used to lower soil p. H are wettable sulfur or ferrous sulfate. Do not use aluminum sulfate to acidify the soil it is toxic to rhododendron and azalea roots. Avoid planting azaleas near concrete sidewalks, driveways or foundations that may leach out lime which raises the p. H.   In rare cases, the p. H may be too low. This is equally serious and must be rectified. The recommendation is usually to use dolomitic limestone. For specific problems, visit Soil Requirements and p. H. IV. Planting Most rhododendron and azalea plants sold at nurseries and garden centers are sold in containers. These plants have a potentially serious problem when the roots reach the container and start circling inside the pot. They become pot bound or root bound. Before planting, these roots must be cut so they dont continue to grow and start strangling other roots. Many apparently healthy plants die when the roots start strangling each other. Can Tree Roots Break Through Concrete' title='Can Tree Roots Break Through Concrete' />To prevent this, it is necessary to remove the plant from the container and examine their roots. If the plants appear pot bound and have a thick, dense mat of fibrous roots along the surface of the root ball, use a knife to make vertical cuts about every 2 inches and 2 inches or more deep, equally spaced around the sides of the root ball. Then use your hands to gently loosen the roots where cuts were made and pull the roots outward. This process stimulates new root growth and allows water and nutrients to penetrate into the root mass. If the roots are not pot bound, it is not necessary to slice them with a knife, but it is beneficial to loosen and pull them outward with your hands. When working with roots, make sure the plant is thoroughly watered. Any roots that dry out will die. V. Fertilizing When rhododendrons and azaleas are not planted in ideal locations they may develop chlorosis. Chlorosis is yellowing of a leaf between dark green veins. It is caused by malnutrition that can be caused by a wide variety of conditions. They include alkalinity of the soil, potassium deficiency, calcium deficiency, iron deficiency, magnesium deficiency, nitrogen toxicity usually caused by nitrate fertilizers or other conditions that damage the roots such as root rot, severe cutting of the roots, root weevils or root death caused by extreme amounts of fertilizer. In any case, a combination of acidification with sulfur and iron supplements such as chelated iron or iron sulfate will usually treat this problem. Holly tone contains these elements and 4 6 4 fertilizer. It is best applied in the spring prior to blooming to make sure the plant is healthy when forming next years flower buds. If you missed applying it in the early spring, it can be applied up until mid summer. Face Recognition Login Software'>Face Recognition Login Software. Rhododendrons do best when left alone in the right conditions. You dont need to use Holly tone or any fertilizer unless the plant shows signs of malnutrition.

Some varieties like full sun to bloom but others suffer from too much sun. This is a trial and error thing unless you know the variety and can look it up. More sun stimulates flowering and but may trigger lace bug infestations. Prune off lower branches of shade trees so that you have high shade above your rhododendrons. This is ideal for a healthy rhododendron bed. For specific problems, visit Sun Shade and Shade Sun Tolerant Rhododendrons. VII. Mulching Rhododendrons do best when they have about a 2 to 3 layer of mulch to hold in moisture, prevent weeds, and keep the roots cool. Since most mulches are organic, they need to be topped off periodically, usually about every year or two. Do not make the mulch over 3 thick.
