Your Paulownia tree should be watered. Then read the instructions that came with your tree. Your tree should now be placed in a gallon container till it is ready to go into the ground. The best way to water the plant is to soak it, then let it dry out before you water it again. If the temperatures are in the high 90's, then only give your tree full sun till noon, then only partial sun till it adjusts. Begin to move it out into the full all day direct sun for a period of a week or so.
Paulownias require a well drained sandy loam soil mix. This mixture should be composed of compost, peat moss, a small amount of sand and your natural soil. We recommend digging a hole that is 2 feet wide by 3 feet deep, and filling it with a 50/50 mixture of natural soil and the above combination of organic matter.
Upon arrival, it is best to use a B1 root stimulant. After a week, begin to fertilize the tree. The Paulownia loves nitrogen. Fertilizing at least once a month is essential in order to ensure the rapid growth of the Paulownia. The trees require a 30-10-10 or a 20-10-10 fertilizer. Be sure to fertilize only at sunset, so as to not burn the trees leaves. The Paulownia tree likes the fertilizer to be sprayed on the roots and leaves. Continue doing this to the trees go dormant in the fall.
All plants are watered before they are packed for shipment, this helps keep the plant moist throughout its long journey. However, some moisture is going to escape. When you receive your plant, thoroughly water it, and place it in a shaded area for a few hours. This will help “perk” it back into shape, and ready for planting. Do not over water! Paulownia soil should dry out between waterings.
