About soil condition, The Red Robin tree grows best in moist to average, well-drained soils, although it is somewhat tolerant of seasonally wet sites and heavy, clay soils. It also does well in sandy soils. This tree has a fast growth rate and is relatively short-lived (30 to 40 years).
So, like the other trees, the red robin tree needs sunlight in order to grow and thrive. This tree prefers full sun, but it can also tolerate partial sun. When choosing a spot to plant your red robin tree, make sure that it will have plenty of sunlight throughout the day.
The temperature condition for a red robin tree is that it should be between 50 and 80 degrees Fahrenheit. The tree will not do well in temperatures below 50 degrees or above 80 degrees. This is why the tree is typically found in warmer climates.
Ideal humidity condition for this plant is between 40-60%. The plant can tolerate lower humidity levels, but may become stressed. If the humidity level drops below 30%, the leaves may begin to turn brown and drop off.
Mentioning fertilizer, this plant requires little attention in that department. A top-dressing of compost in spring is really all that is needed, though a little organic fertilizer can be used if desired. As for the roots, they are relatively shallow and spread out, so be careful not to damage them when tilling or working in the area.
Pruning is an important step in the care of a red robin tree. It helps to maintain the tree's shape and encourages new growth. When pruning, be sure to remove any dead or diseased branches. Also, remove any branches that are crossing or rubbing against each other.
Propagation is typically done through rooting stem cuttings taken from the desired plant. The cuttings should be taken from new growth that is still soft and flexible. Once the cuttings are taken, they can be placed in a rooting medium, such as perlite, vermiculite, or sand. The cuttings should then be kept moist and in a location with indirect light until roots have formed and new growth appears.
Usually, the plant growth rate is rapid during the first 10 years, when the tree may add 3 to 5 feet of height per year. The growth rate then slows considerably, and may add only 1 to 2 feet of height during the next 10 to 20 years. Red robin tree growth is more rapid when the tree is young and when growing conditions are favorable.
Common problems for this kind of plant are powdery mildew, leaf spot, and root rot. These problems can be treated with fungicides, but it is important to catch them early. Pruning out affected leaves and branches can also help.
