Flood Early Warning

No flood risk for the next 10 days. Keep tree bases mulched 10-15 cm (about a palm to a palm-and-a-half thick) using dry rice straw, chopped prunings, dried grass/leaves; keep mulch a hand width away from the trunk to avoid rot. Maintain shallow diversion furrows one hand wide, one palm deep to move rainwater away from trunks during the rainy season. Young trees: keep a small raised ring around the basin about half a palm high to slow splash and hold irrigation water near the roots. This helps reduce splash-borne diseases on leaves and stems, prevents soil erosion around the trunk, and lets water soak in instead of running off. Keep mulch a hand­width away from the trunk, and during heavy rain cut a small notch in the ring so water drains and the trunk and graft union do not stay wet. Bearing trees: keep basins two to three paces across clear of weeds and trash. After showers, check for standing water; if present, open a cut in the ring to drain.

Pest & Disease Early Warning

No elevated pest or disease risk for the next 10 days. Keep the canopy airy by removing crossing branches and lower shoots that touch the ground; avoid wetting leaves late in the day. Collect and destroy fallen fruit daily to reduce fruit-fly breeding; solarize in sealed bags left in the sun for two to three days or deep­bury away from trees. During flowering, avoid overhead irrigation; harvest only when foliage is dry to reduce anthracnose. Keep mulch 10-15 cm (about a palm to a palm-and-a-half) under the canopy, with a hand-width gap at the trunk. Clean pruning tools with soapy water and sun-dry.
