Guava plant maintenance involves a few key aspects:

1. Watering: Guava plants prefer regular watering, especially during dry periods. However, they are susceptible to waterlogging, so well-draining soil is crucial to prevent root rot.
2. Fertilization: Guavas benefit from regular fertilization, particularly during the growing season (spring and summer). A balanced fertilizer with a slightly higher phosphorus content is suitable for promoting fruiting.
3. Pruning: Pruning helps shape the plant, remove dead or diseased branches, and improve air circulation. Prune to maintain a desirable shape and encourage the growth of new branches.
4. Protection from Frost: Guava plants are sensitive to frost, so if you’re in a region with cold winters, consider providing protection during chilly nights to prevent damage.
5. Pest and Disease Control: Keep an eye out for pests like aphids, scales, and fruit flies. Regular inspections and the use of organic or chemical insecticides can help control infestations. Guavas can also be susceptible to diseases like anthracnose and wilt, so proper sanitation and disease management are important.
6. Mulching: Mulching around the base of the plant helps retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulches like straw or wood chips work well.
7. Support for Fruit-laden Branches: Guava branches may need support when heavily laden with fruit to prevent breakage. Use stakes or ties to support the branches as needed.
8. Harvesting: Harvest guavas when they are ripe. The fruit should give slightly to gentle pressure, and the skin’s color should be appropriate for the variety. Be careful not to damage the fruit during harvesting.

Regular care and attention to these aspects will contribute to the health and productivity of your guava plant.
