Bougainvillea is a thorny South American tree creeper that is widely naturalise for its gaudy flowers . These are in fact bracts or modify leafage palisade a little tubular peak . While naturally a climbing plant up to 60 feet long , you’re able to train the bougainvillea into a liberal standing bush and even grow it in container as a house industrial plant . bougainvillea are mostly disease - resistive but can suffer from fungous and bacterial attack , especially when grow in moist conditions .
Sooty Mold
Sooty mold appear as a ok coating of gray or black crock - similar powder on leafage and stems . It is often a consequence of aphid , white tent flap or scale louse plague . The bugs bring about a sweet nub , which surface the open of the leaf and stems and allows ignominious mold to grow on them . Treating the bug with an insecticide or insecticidal soap will slay them from the plant and eradicate the nutrient germ for the mildew . Be sure to identify them and are not killing beneficial insects . Remove ahead of time , unaccented mold by spraying the works with a inhuman piss .
Root Rot
Bougainvilleas are prostrate to settle down decomposition triggered by overwatering . The root organization is delicate and will rapidly die off if surrounded by water - logged soil . Symptoms of root rot include wilt when the soil is sloshed , dieback and chlorotic foliage cause by a lack or nourishing absorption . ensure that potted bougainvillea are permit to drain completely after tearing and cultivate out-of-door works in freely draining soil .
Bacterial Leaf Spot
folio blot in bougainvillea is due to the bacteria Pseudomonas andropogonis and is more plebeian on plant grown in damp area or water from above . It manifests as diminished cherry-red spots on young leaves , which grow larger and get into large tan blotches with a reddish rim . In severe cases whole branch are cover in disfigured foliage , which finally drop off . Leaf point spreads because of splashes of water and contact with infected plants . Treatment consist of pruning away infected department of the plant and reduce any overhead lacrimation .
Fungal Leaf Spot
Fungal foliage spot look very similar to bacterial leaf spot . It is due to excessively moist condition , and treat by reducing lachrymation and stopping any water spray from wetting the leaves . In a ingathering or garden , prune infected plants back to foreclose the infection from spreading and dispose of all cutting .
Other Problems
bougainvillea often get from nutritive deficiency , which turns the parting yellowish , and treat with a fertilizer carry micronutients or a foliar spray . Several insects will eat bougainvillea leaves , particularly the Caterpillar of the bougainvillea inchworm Disclisioprocta stellata . scallop of the leaf edges and irregular leaf scathe are signs of dirt ball plan of attack . plow by manually picking off the pests or with an insecticide or insecticidal soap .
