A potted guava needs sufficient light and room for roots. Check the cultivar and container before planning for flowers or fruit.
Choose a guava for the available climate
Psidium guajava and nursery selections can become substantial trees. Keep cultivar information and check eventual size, cold tolerance and cropping needs. A small sales pot is not a permanent growing plan.
Provide useful light and gradual acclimation
Introduce sheltered growth to stronger exposure in stages. A tropical tree may need suitable winter protection in a container. Conditions at exposed roots can differ from those in nearby ground.
Maintain root moisture with drainage
Use suitable compost and a stable pot sized for the living roots. Water when needed and empty collected water. A dry nursery root ball may remain dry inside damp fresh material, so inspect both after potting on.
Keep crop expectations realistic
Maturity, cultivar, light and pollination influence fruiting. Shape selected healthy growth for an appropriate framework rather than repeatedly topping every shoot. More fertilizer cannot guarantee a harvest or compensate for inadequate root space.
