The oleander is demanding. Regular water and fertilizer inputs are necessary so that the plant can develop magnificently and develop its flowers.
The oleander is known for its great colors. The leaves glow in a rich green and the flowers have bright colors. If the plant is properly cared for, the oleander can unfold its full flower splendor and becomes an absolute eye-catcher in the home garden.
Caring is easy if you know what to look for. The right casting and also the fertilizer play an important role.
The correct pouring of the oleander
The oleander is a thirsty container plant. As a general rule, the oleander should be planted in a bucket protected from rain. The bucket is best placed on a saucer. So the un-absorbed water can be caught and the oleander can take the water when he needs it.
❍ watering in winter
Basically, the oleander must be brought to winter for the winter. The winter quarters, in which it has a maximum of 10 degrees, should be a bright room or the garden shed. The plant is brought indoors as late as possible, because the longer it can stand outdoors, the more robust it becomes. Oleander is frost-resistant down to -5° C and can remain wrapped in fleece at the house wall, until the permafrost comes. In winter, the oleander requires less water. Once a week, the water level should be monitored. If there is no water in the saucer, it is necessary to pour the oleander. If there is still enough water in the saucer, casting can be dispensed with.
❍ watering in the summer
Even in summer it makes sense to put the oleander on a coaster. Since the oleander is one of the thirsty plants, it must be often poured. The water, which is not absorbed immediately, collects in the saucer and can be removed from the plant when it needs it. Basically, the oleander is poured every day. On hot summer days, it may be necessary for the plant to get water more often. So it can happen in July and August, that you have to water the plant three times a day.
What you should know about casting
Many people like to water their plants with rainwater. This should be avoided with oleander but. The oleander loves the calcareous soil and thus calcareous water. But he does not like acid soil and acidic water. The rainwater makes the soil acid over time, which is why the oleander could get some diseases. Frequently it comes to deficiency symptoms, because in the acidic soil important nutrients can no longer be absorbed. It should also be ensured that the oleander never has wet leaves and twigs. This could lead to oleander cancer, which can typically occur on the branches.
If you want to promote the flowering, you should resort to tempered water. The oleander does not like temperature fluctuations very much. If the earth is already very hot in summer, you should always use warm water.
The right fertilizer and the right time
The oleander is one of the few plants that needs a lot of nutrients to develop properly. If you bring the oleander out of its winter quarters in the spring, you should already start with the supply of nutrients. A liquid fertilizer intended for container plants, e.g. this one can be used on the first day after exposure. About twice a week, the oleander should be supplied with this fertilizer.
If you can see after a few weeks that the leaves of the oleander turn darker and get a rich green color, the time has come to use a long-term fertilizer. For this purpose, one selects a long-term fertilizer, which has an effect time of 6 to 12 months, such. this one here. If you want to do the Oleander something good, you can also use some fertilizer lime, because the plant likes the calcareous soil especially like.
When should you use the slow-release fertilizer?
The long-term fertilizer should only be used in spring. On a fertilization in the autumn should be waived in principle. The oleander needs some time to stop growing. Once the oleander stops growing, it forms well matured shoots, which are lignified. This is important because only these shoots are frost-proof and can survive the winter well. Over the winter, the oleander is not active and does not train new shoots. Thus, can be dispensed fertilization in winter.
Can you use too much fertilizer?
The oleander needs a lot of nutrients, which is why the fertilizer is an essential part of proper care.Basically, too much fertilizer can not kill the plant, but disease of the leaves is possible. The so-called leaf margin necrosis can occur. This disease is very easy to recognize because the leaf margins are very dry and later also brown. The signs are similar to a sunburn. If you can recognize the symptoms of necrosis, it is important that the fertilizer is well rinsed out. The entire earth must be largely freed from the fertilizer under running water. Afterwards, fertilization is no longer necessary for the entire year. The oleander usually recovers very quickly and usually quickly forms new, healthy leaves.
