Summer fruit-tree care is a process of checking water delivery, crop load, heat exposure, trunk condition, and developing problems—not automatically adding more water, fertilizer, sprays, or pruning.
This page covers summer priorities for in-ground fruit and nut trees. Newly planted trees should also follow Bare Root Tree Care.
1. Check moisture at root depth
Inspect soil below the surface in more than one location. Measure emitter flow and confirm the wetted area reaches active roots. Expand emitter placement as the canopy grows. Adjust for heat, wind, crop load, soil texture, rain, and mulch rather than using a universal weekly schedule.
2. Maintain mulch without touching the trunk
Mulch reduces evaporation and temperature fluctuation. Keep it several inches from the trunk and graft union, and check beneath it before watering. A wet surface does not prove the full root zone is wet.
3. Watch for sun and heat injury
Sudden canopy opening can expose bark and fruit to intense sun. Avoid excessive summer pruning, especially immediately before hot weather. Use trunk protection appropriate to the tree and climate without trapping moisture or girdling the trunk.
4. Manage crop weight
Thin excessive fruit and support vulnerable branches before they split. Use Summer Fruit Thinning; spacing differs by crop and variety.
5. Use wildlife exclusion safely
Install bird or deer protection before damage begins. Keep netting taut and inspect it so wildlife cannot become entangled. Ensure guards and fencing do not rub or constrict expanding trunks.
6. Diagnose pests and symptoms
Inspect leaves, shoots, fruit, trunks, and irrigation patterns. Identify the pest or disease before selecting a treatment, then follow the current label. Heat, water stress, salinity, and nutrient problems can resemble pest damage.
7. Prune selectively
Remove broken or hazardous growth when safe. Summer pruning may manage vigor for certain crops, but timing and amount depend on species, climate, and disease pressure. See Summer Pruning Fruit Trees.
8. Fertilize only when needed
Do not fertilize simply because fruit is sizing. Evaluate growth, crop load, irrigation, and testing; excessive or late nitrogen can create tender growth. Watch How to Fertilize Fruit Trees.
Summer checklist
- Soil moisture and emitter output checked
- Mulch clear of trunk
- Crop load and branch strength reviewed
- Sun-exposed bark and fruit monitored
- Guards, ties, stakes, and netting inspected
- Symptoms identified before treatment
- Harvested and fallen fruit managed appropriately
Tools and supplies
Browse drip irrigation and fencing and netting based on the diagnosed site need.
Connect Crop Care to the Irrigation Plan
Use the crop-specific guidance above to identify the root zone and growth stage, then apply the soil-based watering framework. Use the orchard irrigation design guide to size zones, choose outlets, and expand the wetted area as trees grow; compare hand watering, drip irrigation, and sprinklers when selecting the broader method.

Helen, I would just follow the directions on your moisture meter.
If I use a moisture meter for established fruit trees, how deep should it go and what setting indicates enough water? In the middle or all the way to wet? Thank you!
Fadia, have you fertilized it with a good fruit tree fertilizer? It just may need more phosphorus, but best to do a soil test to see what your levels are currently at.
Hi
I plant a mango tree from the seed and now it’s around 12 feet but no fruit what I have to do
Thank you
