If you do this, you will have to be really patient until the plant has reached a presentable height. Even if you keep your oleander in great condition, it can become diseased. The most common cause for that are care mistakes. During hot days a sudden falling of leaves can occur. Another cause can be water deficiency. If the leaves grow brown from the outside and become dry, this can indicate a sunburn, or too much fertiliser.
Overly fertilised substrate has to be flushed with a lot of warm water. If leaves colour themselves in a pale green or if the leaf-veins can easily be seen since they are too dark, an iron deficiency can be the cause. The most common cause is not lacking fertiliser, but a wrong ph-Value inside the ground. In this case fresh soil and fertilising chalk will help. To keep oleander healthy, you will have to carry out some steps during its lifetime. The plant should therefore be checked regularly during the year, especially before taking it to its winter quarter and during the colder months.
A great remedy is a repeated spraying with a mixture of rapeseed oil, soap and water. By doing that you have to focus on the underside of the leaf as well. Sign in. Forgot your password? Get help.

I have an Orleander plant whose leaves are turning brown and dry and eventually fall of the plant.
I have made sure that it had enough watering although not too much each time. Can you please offer any explanation. Thank you. I have a large oleander in a pot that I brought indoors for the winter. I have the same problem. I brought my bush inside after having it in the garden. I put it in a big pot with plenty of the sandy soil that it was thriveing in outside.
It did OK until about 2 months ago, then started schriveling up on the leaves. As it did this it put on those pod like things, that eventually fell off. I also wonder if these are seeds to propogate. If anyone can answer these questions, please do! I have had Oleanders in my yard for probably 40 years and have never seen them put on seed pods before. We planted five oleanders in our flower bed where they get plenty of afternoon sun. Three two pink and one red flower OK.
Two of them white have not flowered since planting two years ago. They are very healthy looking except for the flowering. They are pretty close to each other so the watering is the same. We have never fed them. What can be the problem and what should we feed them? I planted the tall type of oleander in my yard 4 of them,but i only have them space about 4 ft apart.

Location Oleanders are quite adaptable, but prefer a location that receives full sun. Timing The best time to plant oleanders is in early spring or fall, although you can plant them any time as long as the ground isn't frozen.
Planting Dig a hole for each shrub that is as deep and two to three times the diameter of the container or root ball, and slightly above soil grade in unimproved soil. Fertilizing New oleander plants usually don't require fertilizer, but it can help increase the growth rate and flowering. During the spring, you should also remove suckers from the bottom of the plant since they can drain the plant's resources and reduce its flowering ability.
Trim down the plant to its desired size, cutting it back to a place just above a node on the stem. The leaf node is a section where three leaves come out from the branch. Making the cut here will force new branches to form at the node, and you will get three new branches when the plant grows back. Avoid pruning more than one-third of the plant when possible.
Oleanders can recover if you prune more, but severely heavy pruning can weaken it some. Usually, oleanders grow rapidly, extending themselves by another 1 to 2 feet 0. If left unattended, oleanders can reach heights between 8 and 12 feet 2. Some oleander plants have even been known to reach 20 feet 6. Dwarf varieties, however, usually stay between 3 and 5 feet 0. Be aware of possible pest and disease problems. Oleanders rarely face problems with pests and disease, but they are not completely immune.
Treat the plant only after you spot a problem, though. The branches and shoots will die and become a blackish brown. Completely remove the infected branches and dispose of them away from the rest of your garden.
Oleander caterpillars are the most common pest. They feed in groups and can demolish young shoots. These pests are about 2 inches 5 cm long with orange-red bodies and black tufts of hair. Quickly apply a pesticide as soon as you spot multiple caterpillars on your plant.
Aphids, mealybugs, and scales can also cause problems, but are rare. Apply an appropriate pesticide as needed.

Best way is to cut the broken end of the limb degree angle just below the lowest node where the leaf grows.
Trim of the leaves except a few on top-end of the limb. Cut an unused plastic bottle, fill it with water and put the stem-cut limb in it. Put it in shaded area indirect sunlight for a few weeks. If you see new sprouts of leaves, it means the limb is rooting. You may also wrap the bottom part of the plastic bottle with a dark plastic bag optional. Change the water in 3 or 4 days, as the oxygen may have depleted. The stagnant water may also attract fungus, which may cause the root and stem to rot.
Transplant to a pot using soil that drains quickly if enough root growth. Not Helpful 2 Helpful 1.
