Today I shall show how to revive dying bougainvillea pant. The same plant you can rescue by help of below mentioned process or steps. Bougainvilleas (Bougainvillea spp.), prized for their masses of colorful floral bracts, grow as evergreen shrubs or groundcovers in U.S. Department of Agriculture plant hardiness zones 9 through 11. It may be cause for alarm when a bougainvillea appears dead, especially following a cold snap that may have killed other plants in the area. If a bougainvillea's leaves are green and lush or simply wilted and able to recover following watering, it is obvious that the plant is not dead. However, when the leaves of a bougainvillea are brown and brittle or drop, especially following a cold event or extensive physical injury to the plant, it is often more difficult to determine if the bougainvillea is still alive and will recover. Bend a portion of a bougainvillea stem near its tip gently. If the stem section bends easily without breaking, it could indicate that that area of the stem is still living. If it snaps with even slight bending, that part of the bougainvillea is dead. The tissue inside a dead stem is brown, not green.
Scrape a very small section of bark gently off of the bougainvillea using your fingernail and look for green tissue just under the outer bark layer. Where you observe green tissue, that portion of the bougainvillea is likely still alive. First scrape a section off near the tip of a branch, and then progress downward, scraping a small piece of bark off every foot or so until you locate green tissueCut bougainvillea stems that appear dead at the top but still green and living nearer the ground back into living tissue. Make any cut slightly angled and just above a bud or junction with another stem. Check the cut surface to ensure you cut far enough down the stem that you are severing green, living tissue. If the cut surface is completely brown, make a new cut nearer the ground into a living part of the stem.
Cut the bougainvillea stems that appear completely dead, with just brown and brittle tissue, to about 2 inches above the soil surface.
Water the bougainvillea deeply and infrequently, wetting about the top 6 inches of soil around the bougainvillea whenever the soil feels dry to the touch about 2 inches below the soil surface.
Monitor any stems you left standing because they contained living tissue occasionally, looking for the appearance of any new growth. Cut the stem back further, if needed, to remove any portion of the stem above emerging buds that is dead and failing to produce new growth.
Bougainvillea plants normally lose many leaves following a bloom period. A flush of new growth will generally follow this normal leaf drop.
Do not perform corrective pruning immediately after cold damage occurs as the extend of damage is sometimes not apparent for weeks, and another cold spell could have a greater impact on a pruned bougainvillea than on a bougainvillea that still has dead wood attached. Instead, monitor the bougainvillea for signs of new growth before removing portions that are obviously dead once no more frost is likely.
