How to water Oncidium (how often) how to fertilize Oncidium

Oncidium is a common potted orchid. Although the flowers are not as luxurious as other flowers, they also have their own characteristics, fresh and elegant, so many people will plant a pot with very fine care, but they still die. The reason is that they are overwatered, but how to water it? Let's take a look.

How to water Oncidium (how often)

The general watering principle is to dry and wet alternately, each watering should be thoroughly watered, and the next time you should wait until the substrate is slightly dry. It is not necessary to water the flower after blooming, it is necessary to water it when it is dry, it is usually watered every 7-10 days (soak the flowerpot in water for 5 minutes), and it is usually sprayed.

How to fertilize Oncidium

Proper fertilization is very important for Oncidium. It is necessary to use a small amount of fertilizer as base fertilizer when planting Oncidium. In general, the substrate of potted Oncidium is not easy to conserve water and fertilizer, so it is necessary to apply some local release fertilizer in the pot. This can increase the fertilizer effect of the basin soil, and then fertilization can be applied according to various conditions. It is generally recommended that bean cake water or bone meal can be applied once a month.

Except when the temperature is too low in late autumn and winter, liquid quick-acting fertilizer should be applied every two or three weeks, which can be applied to the leaves and roots. When Oncidium is about to blossom, be sure to apply adequate phosphorus and potassium fertilizer. In order to effectively control diseases and insect pests, Oncidium can be often irrigated with carbendazim or methyl topiramate.

Propagation method of Oncidium

1. Ramet propagation

Oncidium is a compound-stemmed orchid. When the plant is mature, we need to wait for these plants to grow false bulbs, and then cut off the seed plants, usually cutting off the false bulbs with two buds. This can be directly planted in a basin with water moss, and the air humidity needs to be higher, which can promote the false bulbs with buds to grow new buds and roots more quickly. This method of ramet propagation is usually carried out after Oncidium blossoms or in spring or autumn.

2. Aquatic culture

This kind of training method is also very technical. Oncidium's aquatic culture needs to be cultivated in a professional hydroponic flower base for more than half a year, so that Oncidium can grow aquatic roots and can fully adapt to the still water environment.

What if Oncidium doesn't blossom?

1. Potted soil: at the beginning, it is generally mixed with charcoal soil and decaying soil, and the bulbs need to be exposed on the soil surface when planting.

2. Light: in winter, Oncidium can be placed near the balcony where there is plenty of light, which can meet the light needed for growth, and at the same time spray some water fog around it on time, because it likes to be moist. In other seasons, we can put it in a shady place with better light, which can not only prevent the influence of high temperature but also meet the lighting demand, but should avoid exposure in strong light.

3. Disease: Oncidium sometimes gets black spot, so we should remove the damaged leaves in time and spray some fungicides to prevent the disease from affecting the flowering of Oncidium.

4. Fertilization: Oncidium should be fertilized in a small amount because of its thin roots, which can make the fertilizer less, which can supplement its nutrition and blossom better.

The ornamental value of Oncidium lies in its lovely flowers, so if it doesn't blossom, isn't it less ornamental value? so when you find that your Oncidium doesn't blossom for a long time, there is actually a reason. Be sure to find the right reason and solve it in time. Soon you will see a pot of blossoming Oncidium.
