The answer to 'how to maintain tree' is to regularly prune, water, and fertilize your trees to keep them healthy and thriving. Proper tree maintenance involves pruning to remove dead or damaged branches, watering during dry spells, and applying fertilizer to provide essential nutrients.
Pruning should be done annually or every 2-3 years to shape the tree and remove any hazardous branches. Water trees deeply 1-2 times per week during the growing season, providing about 1 inch of water. Apply a slow-release fertilizer in early spring to feed the tree throughout the year. Monitor for pests or diseases and address any issues promptly.
