Leaves are typically medium to moody green , shiny , and ovate , with fine toothed edge . depart in size from 1/2 in to 6 inches , five flower petal to more than 30 , and in closely every color . Often the flowers are very fragrant . Most varieties produce on foresightful cane that sometimes go up . Unfortunately , this best-loved plant life is quite susceptible to a variety of disease and blighter , many of which can be controlled with undecomposed cultural practices .

Problems
Prevention and Control : keep weeds down and apply block out on windows to keep them out . get rid of or discard infest plants , keep them away from non - infested industrial plant . Trap with yellow sticky cards or take advantage of natural enemies such as predatory hint . Sometimes a good steady cascade of piddle will wash them off the plant . confer with your local garden center professional or county conjunctive extension office for legal chemical recommendations . Pest : Spider MitesSpider mitesare small , 8 legged , spider - alike creatures which flourish in hot , ironical condition ( like het houses ) . Spider mites feed with piercing mouth parts , which cause plants to appear yellow and stippled . Leaf drop and plant demise can fall out with heavy infestations . Spider mites can multiply quickly , as a female can lay up to 200 eggs in a life span of 30 days . They also produce a web which can cover infested leaves and flowers .
Prevention and Control : Keep weeds down and remove infested plant life . Dry air seems to decline the job , so make certain plants are on a regular basis water , especially those prefer high humidness such as tropicals , citrus , or tomatoes . Always curb new plants prior to add them home from the garden center or baby’s room . Take vantage of rude enemy such as ladybug larvae . If a miticide is recommended by your local garden centre professional or county Cooperative Extension office , read and stick with all label directions . contract your elbow grease on the undersurface of the leaves as that is where wanderer touch generally live . Pest : WhitefliesWhitefliesare humble , winged insects that look like diminutive moth , which round many types of plants . The flying grownup stage favor the underside of leaves to eat and breed . whitefly can procreate quickly as a female person can lie up to 500 eggs in a life span of 2 month . If a plant is overrun with whitefly , you will see a cloud of flee insects when the works is shake up . Whiteflies can weaken a plant , eventually pass to plant death if they are not checked . They can transmit many harmful plant virus . They also create a sweet substance called honeydew ( covet by pismire ) which can direct to an untempting black control surface fungal maturation called jet mold .
potential controls : keep weeds down ; use block out in window to keep them out ; dispatch infested plants away from non - infested plant life ; use a reflective mulch ( Al foil ) under plant life ( this repels whitefly ) ; trap with lily-livered unenviable card game , apply labeled pesticide ; encourage natural enemies such as parasitic wasps in the garden ; and sometimes a good unshakable exhibitioner of urine will wash them off the plant . Pest : AphidsAphids are small , soft - bodied , behind - moving insect that suck fluids from plant . Aphidscome in many colors , ranging from green to brown to dim , and they may have extension . They attack a wide range of plant species cause stunting , flex parting and buds . They can transfer harmful flora virus with their piercing / sucking mouthparts . Aphids , broadly speaking , are just a pain , since it take in many of them to cause serious works damage . However aphids do bring out a sweet sum call honeydew ( covet by ants ) which can lead to an unattractive black surface development cry sooty mold .
Aphids can increase quickly in numbers and each female can grow up to 250 live nymphs in the course of a month without union . Aphids often appear when the environment changes - spring & fall . They ’re often massed at the tips of branches feeding on succulent tissue paper . Aphids are pull to the color yellowness and will often hitch on yellow clothing .
Prevention and Control : Keep weeds to an absolute lower limit , especially around desirable plant . On victuals , moisten off infect area of plant . peeress hemipteran and lacewing will feed on aphids in the garden . There are various product - organic and inorganic - that can be used to control aphids . Seek the passport of a professional and trace all recording label subroutine to a teeing ground . Fungi : Powdery MildewPowdery Mildewis usually chance on plants that do not have enough air circulation or passable light . problem are bad where Nox are coolheaded and days are warm and humid . The powdery white or grayish fungus is unremarkably found on the upper surface of leaves or fruit . Leaves will often plow yellow or brown , kink up , and neglect off . newfangled foliage emerges crinkled and twisted . Fruit will be dwarfed and often swing early .
Prevention and Control : Plant repellent varieties and blank space plants the right way so they welcome adequate luminousness and airwave circulation . Always water from below , observe water off the leaf . This is paramount for roses . Go soft on the nitrogen fertilizer . Apply fungicides fit in to label directions before trouble becomes severe and follow counselling on the nose , not missing any required treatments . Sanitation is a must - clean up and take out all leaves , flowers , or debris in the fall and demolish . Pest : CaterpillarsCaterpillars are the immature form of moth and butterfly stroke . They are voracious feeders snipe a wide variety of works . They can be highly destructive and are characterized as folio feeders , stem borers , leafage rollers , cutworms and tent - formers .
Prevention and Control : keep weeds down , scout item-by-item plants and hit caterpillars , apply label insecticides such as soap and vegetable oil , take reward of natural enemy such as parasitic wasps in the garden and utilise Bacillus thuringiensis ( biologic warfare ) for some caterpillar species . Fungi : Black SpotA known rise disease , Black Spotappears on untested leaves as irregular black circles , often have a chicken halo . Circles or spore colonies may grow to 1/2 inch in diameter . Leaves will turn yellow and drop off , only to produce more leaves that will follow the same pattern . Roses may not make it through the winter if black speckle is severe . The fungus will also bear on the size and quality of flowers .
Prevention and Control : institute resistant multifariousness for your area . Always pee from the ground , never overhead . Practice good sanitation - clean up and destroy detritus , especially around plants that have had a problem . When rationalize rose wine , even deadheading , dip pruners in a bleach / water solvent after each cut . If a plant seems to have chronic black smudge , polish off it . A 2 - 3 inch thickset layer of mulch at the foot of industrial plant reduces splashing . Do not wait until dark office is a vast trouble to control ! Start early on . Spray with a fungicide labeled for black spot on roses . disease : BlightBlights are do by fungus kingdom or bacterium that down plant tissue . Symptoms often show up as the rapid spotting or droop of foliage . There are many different blights , specific to various plants , each requiring a varied method of dominance .
Miscellaneous
In milder climates , this appendage is not necessary , but a good layer of mulch and continued tearing up to frost and periodically through winter is a good idea . The good meter to dress no matter where you survive is at the destruction of the dormant season , when bud are start to swell . Glossary : VirusesViruses , which are smaller than bacteria , are not living and do not double on their own . They must trust on the cellular mechanisms of their hosts to replicate . Because this greatly interrupt the cellular telephone ’s functionality , outward star sign of a viral infection consequence in a plant disease with symptoms such as unnatural or scrawny development , damaged yield , stain or fleck .
Prevention and Control : Keep virus carrier such as aphids , leafhopper , and thripid under command . These plant alimentation insects spread virus . Viruses can also be introduced by septic pollen or through plant life openings ( as when prune ) . start bykeeping the pathogen outof your garden . unexampled plants should be check , as well as tools and subsist plant . apply only license seed that is deemed disease - free . Plant only resistant varietiesandcreate a discouraging environmentby rotating crop , not planting nearly relate plants in the same area every year .
