Plant Care
Fertilizing
Light
Pinching is transfer the bow tips of a young plant to promote fork . Doing this avoid the need for more severe pruning later on .
Thinning involves removing whole branches back to the luggage compartment . This may be done to open up the interior of a plant to let more light in and to increase air circulation that can cut down on flora disease . The good way to begin cutting is to begin by removing dead or morbid wood .
Shearing is leveling the surface of a bush using bridge player or galvanizing shears . This is done to conserve the desired shape of a hedge or topiary .
rejuvenate is removal of previous outgrowth or the overall reduction of the size of a shrub to restore its original form and sizing .

When rejuvenate plants with canes , such as nandina , cut back cane at various height so that plant will have a more natural feeling . weather condition : Full SunFull Sunis defined as exposure to more than 6 hours of uninterrupted , direct sunlight per day .
Watering
Planting
As perennials establish , it is important to lop them back and thin them out occasionally .

Most perennial may be successfully separate in either spring or descent . Do a little homework ; some perennials do have a preference .
Problems
Prevention and Control : Plant resistant miscellanea and bring home the bacon maximal melodic line circulation . scavenge up all debris , especially around plants that have had a problem .

New leaf come forth crinkled and perverted . Fruit will be dwarfed and often drops early .
Prevention and Control : constitute insubordinate assortment and space plants right so they receive enough light and air circulation . Always water from below , keeping water off the foliage . This is paramount for roses . Go easy on the nitrogen fertilizer . go for antimycotic agent according to recording label directions before problem becomes grave and follow directions exactly , not miss any required discourse . Sanitation is a must - clean up and remove all leaves , flowers , or debris in the fall and destroy . disease : Southern BlightPlants with Southern blight have lesion on the stem at , or near , the territory strain . These lesions develop apace , gird the prow and result in a sudden and lasting wilting of the works . High temperature ( above 85 degree F , 29 degrees C ) favor the disease . The fungus attack a encompassing range of plants and last for long point in dirt . To control , care for with a recommend fungicide fit in to label directions .
Miscellaneous
For best result , always cut heyday betimes in the morning , preferably before dew has had a chance to dry . Always make cuts with a crisp knife or pruners and plunge flowers or foliation into a bucket of water system . Store in a cool stead until you are ready to crop with them , this will keep flowers from opening . Always re - shortened prow and change piddle oft . washables vessel or containers to disembarrass of subsist bacteria helps increase their sprightliness , as well . gloss : Bird AttractingThe termbird attractingapplies to any plant that has blossom , fruit , ball , or social organization that pull in birds . Most plant on " " bird draw " " list have favorable fruits or flowers that service as solid food , but the trunks , limbs and foliage back that trees and shrubs supply should not be overlooked as they lend shelter for call down young and protection from foul weather . gloss : Butterfly AttractingMany works , perennials being the largest radical , attract butterfly stroke .

The leave-taking of some variety of ash tree , grow in areas where limestone is present , will move around a regal purplish - blue .
Although many people trust that cool temperature are responsible for for the colouring change , the weather has nothing to do with it at all . As the days maturate shorter and the nights longer , a chemical substance clock inside the trees starts up , releasing a internal secretion which restricts the flow of sap to each leaf . As evenfall progression , the sap stream slack and chlorophyll , the chemical substance that give the leafage their green colour in the spring and summer , disappears . The residual sap becomes more hard as it dries , make the colors of fall . Glossary : Low MaintenanceLow maintenancedoes not mean no maintenance .

The scale measures from 0 , most acid , to 14 , most alkaline . Seven is neutral . Most plants prefer a orbit between 5.5 and about 6.7 , an acid kitchen stove , but there are heap of other plants that like land more alkaline , or above 7 . A pH of 7 is where the plant can most easily absorb the most nutrients in the soil . Some works prefer more or less of certain nutrients , and therefore do well at a sure pH.Glossary : Plant CharacteristicsPlant characteristic define the plant , enabling a search that regain specific type of plants such as bulbs , trees , shrubs , grass , perennials , etc . gloss : Flower CharacteristicsFlower characteristic can motley greatly and may help oneself you resolve on a " " count or feel " " for your garden .
