Answer: No. You should wait at least 1 - 2 weeks before repotting to allow the plant to acclimate to its new environment.
PLEASE NOTE: You should ALWAYS separate your new plants from the rest of your plant collection for at least one week to watch for pests and diseases.
If you purchase a new plant from your local nursery, you should let the plant acclimate to your home for at least one week before repotting. The humidity at the nursery is usually higher than in an average home so your plant might experience a decline if there is a huge difference in humidity and sunlight. If you repot the plant immediately, the plant will be shocked even further. So please wait for one week before repotting.
If you purchase a new plant online, you should wait for at least 2 weeks before repotting. Plants shipped online depend highly on how the online nursery package your plants. If securely packaged, the plant will experience little to no stress during shipment. This is the best case scenario. However, if the plant suffers from shipping stress, it will lose leaves and sometimes decline before bouncing back. It’s important to let the plant recover from shipping stress for at least one week. Place it under indirect sunlight and give it high humidity. Monitor for signs of further decline. If it dies within a few days, you should reach out to the seller. Most plants will acclimate to your new home in about 1 - 2 weeks. If you see signs of growth, that means the plant is happy and has acclimated to your home. After 2 weeks, it is safe to repot the plant.
