Causes of Sideways Growth in Bougainvillea
There are four main factors that commonly cause Barbara Karst bougainvillea to grow sideways:
Insufficient Sunlight
Bougainvillea are sun-loving plants that thrive in full sun locations Barbara Karst bougainvillea needs at least 6 hours of direct sunlight daily for optimal growth and flowering Without adequate sunlight, the plant stems start to get leggy and lean sideways searching for light.
Make sure to situate your Barbara Karst bougainvillea in the sunniest part of your yard. Trim back any branches or vegetation that shade the plant. Consider supplemental grow lights if natural sunlight is insufficient.
Underwatering
Inconsistent watering leads to plant stress, causing bougainvillea to wilt and bend. While drought tolerant when established, bougainvillea still require 1-2 inches of water weekly in hot weather. Soil should be allowed to partially dry out between waterings.
Give your Barbara Karst bougainvillea a deep watering 2-3 times a week during summer and reduce frequency in winter. Check soil moisture before watering.
Lack of Support
Bougainvillea are vining plants by nature and will grow along supportive structures. Without a trellis, fence or post to climb, Barbara Karst branches end up sprawling sideways along the ground seeking support.
Install a sturdy trellis, post or wire support structure near your bougainvillea. Gently tie new growth to direct it along the support.
Improper Pruning
Overly-aggressive pruning or incorrect techniques disrupt the plant’s natural shape. Removing too much growth at once stresses the plant, causing excessive horizontal branching.
Prune Barbara Karst bougainvillea lightly and frequently. Use sharp bypass pruners to remove dead wood or overgrown stems just above leaf nodes.
How to Fix Sideways Growth
If your Barbara Karst bougainvillea is already growing horizontally, take corrective steps to get it growing upright again:
-
Stake the main stems and loosely tie them to the support to train upward growth.
-
Make clean cuts at 45 degree angles just above outward facing buds to encourage vertical branches.
-
Apply a nitrogen fertilizer to stimulate strong vertical growth. Follow label directions.
-
Improve sunlight exposure and reduce competition from nearby plants.
-
Provide consistent deep watering when top few inches of soil become dry.
-
Monitor for pests like aphids that can distort growth if infestations occur.
-
Be patient! It may take a full growing season to reorient sideways stems.
Encourage Upright Habit
Prevention is key to keep your Barbara Karst bougainvillea growing happily upright year after year. Follow these tips:
-
Situate in full sun – at least 6 hours of direct sun daily.
-
Install sturdy supports early before planting. Use adjustable plant rings or hoops if needed.

Water 1-2 inches weekly. Check soil moisture before watering.
-
Apply balanced fertilizer monthly during growing season.
-
Prune lightly and often to direct growth and shape.
-
Monitor for pests like thrips that distort growth if left untreated.
-
Shelter from strong winds that can blow stems sideways.
When to Worry
While some sideways growth is normal, contact a professional if you notice:
-
Stems growing from just one side of the main stem
-
Leaning more than 45 degrees with excessive horizontal side shoots
-
Wilting, yellowing leaves, branch dieback
-
Weak overall growth and very few flowers
-
Evidence of pest infestation like sticky honeydew or scarring
-
Soil stays soggy for extended time after watering
