Bougainvillea was discovered in 1768 by Admiral Louis de Bougainvillea on a ocean trip that take in him to the vine ’s native home ground , Brazil . The bougainvillea vine is an evergreen that can be prepare to produce in containers , hang handbasket or to stand up to three or four feet in tiptop .
Fungal and Bacterial Leaf Spot
Fungal and bacterial leafage smear will appear as small , reddish brown spots on unseasoned folio . The spots will grow into magnanimous circular or on an irregular basis mould , dark spots . In dry conditions , they will progress slowly . In blind drunk atmospheric condition , they will spread much faster . The spots become lesions with a tan middle , surround by a dark , ruby-red brown margin . The edge of the leaves may become ragged . The bougainvillea will become defoliated in the most severe vitrine . Prevention is the skillful course of action . Make certain the industrial plant develop enough aviation circulation to assist keep the leave ironical . Do not allow the branches to overlap . Remove and dispose of any septic leaves or in severe cases , the whole plant .
Mineral Deficiencies
The wrong balance of minerals can cause several disease in the bougainvillea industrial plant . foliage spots that are jaundiced or tan on older leaves can be a planetary house of magnesium deficiency , especially in yellow variety . This can also be because of too much watering On new development , it could be either a magnesium or iron deficiency . stunt , pale young growth where the nervure of the leaf stay green is another sign of an iron deficiency . When one-time leave-taking turn pale green and the veins red , and new growth is stunted , it is a nitrogen inadequacy . The plant needs phosphorus when the vein turn to Marxist or royal and the rest of the plant has a purple looking . Potassium deficiency is the job when the edges of the old leaves grow purple and the peak brownness . A Zn lack , which is rare , make the same yellow or brown spots as magnesium , but the leaves will be twisted . It is a calcium deficiency if dead spots come along in young ontogeny and the tip die out . Applying a complete micro - nutrient portmanteau will get the bougainvillea back in balance .
Diseases Caused by Insects
Insects can not only rust away the leave of the bougainvillea , they can cause moldy fungus diseases . The green aphid feeds on the new industrial plant tissue and sucks out the fluid . A great infestation can cause the leave to curl , turn yellow and become malformed , and the plant life growth to be stunted . Aphids also leave behind a viscid substance call honeydew that attracts other insect , sour black , and turns into sooty mould fungus .
mild scale insects also secrete honeydew . They run on the fluid - conducting tissues of the plant . Soft scales include bootleg scale , brownish soft scale and the mealy hemipteron . It is the young scales that do the damage . The leaves will droop , turn yellow and drop off early . Scales can also curl the leaves or break the flowers . Before establish a newfangled bougainvillea , ensure none of the neighboring plant have any infestations . If they do , take concern of them first . ensure all septic part of the works are removed and destroyed .
