Symptom
Young fruit dropping
Plants shed fruit they cannot support after stress, poor pollination or pest attack. Some drop is natural: many fruit trees thin themselves in early summer.
Cut a fallen fruit. Grubs inside point to pests; seedless or undeveloped fruit to poor pollination; healthy fruit to stress or natural thinning.
