How to Acclimate Guava Trees
If your new plants or trees from Stark Bro’s arrive in a pot and already display tender leafy growth, then they were likely grown in our greenhouses. Here are a few steps we recommend you follow to acclimate these plants and trees (or harden them off) before planting outdoors:

Acclimation Steps for Potted & Bagged Trees
Upon arrival, unbox your plants and trees, and keep them in the pots they arrived in. Place them in a sheltered, semi-shady spot outdoors – like on a back porch. After a day or so, move them to a sunnier spot. Water your plants upon arrival, but then allow the top of the soil to dry out – this also contribute to the hardening-off process.
Observe the foliage – if signs of leaf injury appear, move those plants or trees back into more filtered sunlight and an area protected from harsh winds. Air movement in outdoor conditions is equally important for hardening-off the plant. Cool air helps harden the tender new growth but do bring plants back indoors at night if temperatures are expected to reach close to or below freezing.
After 2-3 days of acclimating your plants and trees, and if the weather conditions are right, your new plants and trees are ready to be planted in a permanent location. Your new plants and trees should be able to handle the outdoor conditions, as long as temperatures are expected to stay above 50ºF. For best results, try to plant on a cloudy day.
It will become necessary to move your container-grown plants indoors to overwinter when temperatures drop below 60 degrees. Prepare your plants for this by gradually shading the plants over a 3-week period.
Please note: these are general recommendations. Your particular growing environment might require a slight variation on these guidelines, since some plants can take more time (or less time) than others to harden off. Factors like the current year’s weather, individual plants, and your location may affect the process. If conditions outdoors are too harsh, keep potted plants near a sunny window, water and take care of like a houseplant until conditions are better. Then start the process with hardening off your plants.
