Calendar of cultivation and care of oleander

January

To do a good job of preventing cold, the branches should be tied and supported to prevent them from being broken by snow. The snow should be cleared in time after the snow.

February

Transplantation should be carried out in spring, base fertilizer should be applied in the planting hole, and the first watering after planting should be thorough. Transplantation in other seasons requires bringing the soil ball with you, and in summer the leaves should be pruned appropriately to reduce leaf evaporation. For frozen areas, short pruning should be carried out before germination, and bud removal should be done to facilitate the recovery of the tree. For shaping and pruning, generally three main branches are retained on each trunk, and three branches are left on each trunk, so that a "three branches and nine tops" crown is formed in the future.

March

For propagation by cuttings, cut 15-20 cm long branches, tie 20 branches into a bundle, immerse them in 20℃ clean water with 1/3 of the branches immersed in water, change the water frequently. After 7-10 days, when the branches immersed in water turn white and the tops start to become sticky, take them out and insert them into the seedbed. You can also soak it in water for 30-40 days, take it out and insert it into the sand bed after it takes root, and it will take root in about a month. Applying liquid fertilizer once is beneficial for growth and flowering.

April

From the time the plants begin to bloom until October, pay attention to tillage and weeding, and prevent and control diseases and pests.

May

Cut off the blooming and withering flowers in time to avoid wasting nutrients.

June

Layering propagation is carried out in the rainy season. Select plants that are more than one year old and have many branches as the mother plant. Select branches of the current year with a diameter of more than 0.8 cm. Remove the leaves 33 cm away from the top, twist the bark, fold it into an "8" shape, and press it into the soil to a depth of about 10 cm. Cover the soil and compact it to prevent the branches from popping out of the soil after watering. Water it once after pressing, and then water it when the soil is dry. It will take about 60 days for the roots to grow and separate.

July

Prevent water accumulation after rain and remove weeds and dead flowers in time. Oleander has a strong ability to sprout, and many sprouts will grow from the base during its growth period. In order to reduce nutrient consumption and maintain its beautiful appearance, they should be removed or cut off in time.

August

Same as last month’s management.

September

Same as last month’s management.

October

Same as last month’s management.

November

Apply phosphorus and potassium fertilizers once after flowering to promote healthy growth.

December

Do a good job of soiling and cold prevention. The seedlings should be covered with grass to prevent frost, and the suckers and overcrowded branches should be pruned. Control the moisture and keep it on the dry side.
