For example, drive several stakes into the ground around the plant, and attach the stakes to the stem with soft ties or strips of rubber. As the leaves age, this scurf eventually falls off. Shallowly planted palms are structurally unsound and can easily topple over in moderate to high winds (Figure 21). This nutrient deficiency is most common in container-grown palms, whereas potassium, manganese, and magnesium deficiencies are more prevalent in landscape situations. If you prune too many palm trees, clean the tool with alcohol or hydrogen peroxide to stop diseases from spreading. OverGrown, Remove suckers with hand shears any time of year as soon as they appear, cutting below the surface of the soil.

Avoid the use of magnesium oxide as a treatment if the soil has a neutral or alkaline pH, as it is quite insoluble in soils with a high pH. Prevent wounds on palm trunk whenever possible, and treat wounds that do occur by applying broad-spectrum fungicides and bacteria treatments to the wound area. You can post now and register later. In heavier clay soils, the rate of potassium leaching is reduced. In general, infected palms should be removed and destroyed promptly to reduce disease spread. . Cool nights all year round. Visual symptoms are usually sufficient to diagnose this problem. Any new growths arising from the clump are seedlings that have germinated, not vegetative shoots from the original clump. All orders placed will be age verified. I thank you! The best equipment is a hand pruner for smaller palms, and a sharp pruning saw for larger palm trees.

Below is a brief explanation of how to repair split bark caused by different conditions. This, however, needs patience because it may take months before the tree regains its shape. Since all sabal palms are seed propagated and thus are genetically different, some will retain their old leaf bases for 50 years or longer, while others shed their old bases after 510 years.
