Growing Requirements for Dendrobium officinale: Soil and Ambient Temperature Are Key
Summary Soil requirements: choose peat, fern root, tree bark, etc. as the transplanting substrate. Temperature requirements: the suitable temperature for growth is 12-35°C. Light requirements: it is suitable for growing in a shady, damp, ventilated, semi-shaded and semi-sunny environment, and direct sunlight must be avoided in summer. Humidity requirements ⟦4 <p class="cintro"><span>Summary</span>Soil requirements: choose peat, fern root, tree bark, etc. as the transplanting substrate. Temperature requirements: the suitable temperature for growth is 12-35°C. Light requirements: it is suitable for growing in a shady, damp, ventilated, semi-shaded and semi-sunny environment, and direct sunlight must be avoided in summer. Humidity requirements: keep humidity above 60%. Watering frequency: water once a month in winter; water once every 2 weeks in spring and autumn; water once a week in summer. Water quality requirements: use neutral water or slightly acidic water.</p> <p></p> <p><strong>1. Soil requirements</strong></p><p>1. The main reason Dendrobium officinale cannot be planted in soil is that it has aerial roots and shallow roots, which means good air permeability is required. Generally, by imitating the growing environment of wild Dendrobium officinale, if stones are chosen as the substrate, air permeability will be better, but water retention will also be poorer.</p><p>2. It can be seen that a single substrate can hardly satisfy the conditions of both water retention and air permeability at the same time, so the substrate for artificially cultivating Dendrobium officinale should preferably be loose, breathable, not prone to mold, well-drained, free of pathogens, and free of hidden pests. During this period, peat, sphagnum moss, mountain stone, wood shavings, fern root, tree bark, board edges, mushroom bran, sawdust, etc. can be chosen as the transplanting substrate.</p><p></p><p><strong>2. Temperature requirements</strong></p><p>The survival temperature of Dendrobium officinale is -10°C, and the suitable temperature for growth is 12-35°C. When the temperature is relatively high in summer, shading and ventilation are needed inside the greenhouse, and frequent misting is needed to maintain moisture and lower the temperature. When the temperature is relatively low in winter, insulation is needed.</p><p></p><p><strong>3. Light requirements</strong></p><p>1. Dendrobium officinale is a semi-shade and moisture-loving plant. Wild Dendrobium officinale generally grows attached to rock cliffs at relatively high altitude, or on the bark of trees in humid environments, because these attachment hosts (rock, bark) themselves contain very little water, and some even contain no water at all (rock).</p><p>2. Dendrobium officinale is an aerial-root plant and mainly obtains nutrients by absorbing moisture and nutrients from the air. These factors all determine that Dendrobium officinale needs to be planted in a shady, damp, ventilated, semi-shaded and semi-sunny environment.</p><p>3. The native environment of Dendrobium officinale is always under tree shade and in shaded places, so the growing environment needs appropriate shading. When sunlight is strong, shade it to prevent direct sunlight, and a shade shed can be built.</p><p></p><p><strong>4. Humidity requirements</strong></p><p>During the growth of Dendrobium officinale, a hygrometer should be provided, and humidity can be kept above 60%. In overcast and rainy weather, when humidity is above 90%, ventilation needs to be strengthened to avoid the occurrence of bacterial and fungal diseases.</p><p></p><p><strong>5. Watering frequency</strong></p><p>In winter, water once every 1 month; in spring and autumn, water once every 2 weeks; in summer, water once every 1 week.</p><p></p><p><strong>6. Water quality requirements</strong></p><p>When watering, mist frequently and avoid drenching thoroughly too often. Usually, wait until the substrate is dry before drenching thoroughly. The water quality needs to be neutral water or slightly acidic water.</p><p></p><p><strong>7. Pest prevention</strong></p><p>Dendrobium officinale suffers relatively few pests and diseases. Generally, when good ventilation is maintained, no special pesticide control is needed. If pests occur, they need to be dealt with according to the specific situation.</p><p></p><p><strong>8. Fertilization requirements</strong></p><p>Fertilization requires applying thin fertilizer frequently, and heavy fertilizer must absolutely not be used, otherwise fertilizer damage is likely to occur.</p><p></p><p><strong>9. Ventilation requirements</strong></p><p>Ventilation and air circulation are also relatively important to the roots in the substrate, so it is recommended to choose materials with relatively good air permeability. Also, when watering, be sure to water thoroughly to bring fresh air into the substrate. Circulating air is very important to Dendrobium officinale, and at the same time it can also reduce the occurrence of diseases.</p>
