dryness
'Red Robin', like other varieties of red-leaved loquat, is sensitive to drought. Moisture in the soil is important so that the plants can compensate for the loss of water. If they do not get water for a long time in the summer months, they shed their leaves. The shrubs save energy in order to survive the suboptimal conditions.
Regular watering supports the vitality of the plant. The water is given when the top soil layer has dried. In hot months, pour penetratingly. When planting, make sure it is in a sheltered location in the Penumbra. The direct sun in combination with warm winds increases water evaporation. Herb-rich undergrowth favors a moist microclimate near the ground. As a result, the water evaporates from the ground more slowly.
Waterlogging
The roots of the common loquat do not tolerate too wet conditions in the substrate. If the water builds up, the roots will rot. They no longer absorb water, causing the leaves to dry out and fall off. While drought stresses the plant, moisture causes damage.
By choosing the ideal location for your loquat, you can prevent waterlogging. 'Red Robin' likes a well-drained substrate. A sandy soil is ideal because the water can seep away well here. Heavy loam or clay substrates hold back the water.
Permafrost
Although 'Red Robin' is hardy, prolonged sub-zero temperatures can harm it. In the harsh winter months, the soil in the deeper layers freezes. The roots of the common loquat cannot absorb water. In the following spring they lose their green leaves. This phenomenon is favored by a sunny location. The winter sun minimizes the water reserves of the leaves.
Before winter, water your medallion plentifully and make sure it is in a partially shaded spot. Spread brushwood, fir branches or fleece on the ground to protect against ground frost. Container plants overwinter in a mild and sheltered place. Water these shrubs regularly when the top soil layer has dried.
