I need technical advice. How do I check my soil? What pH should I have? What fertilizer is needed? How do I prune my trees?

Paulownia likes free draining sandy loam type soils. Paulownia will not tolerate any low or wet land. Paulownia requires a pH of 6.5 and above. You will need to test your pH each season and fertilize accordingly. Early spring and then again prior to fall. Pruning is required for the first 2 years. Pruning every 4-6 weeks in the first growing season will ensure good height growth. Once your tree reaches at least 15′ it is not necessary to keep pruning the suckers out. Shade tree pruning: You only need to prune your tree up to where you want the canopy to start. If you want your canopy to start at 8 or 10 feet then you do not need to prune any higher. It is very important in all cases of pruning that you leave at least 8-10 main sets of leaves on the tree at all times. Do not over prune.

Why do I need to space my Paulownia trees?

Paulownia is very light sensitive and needs to be planted on equal distances. 12’ x 12′ = 300 trees per acre – 14′ x 14′ = 220 trees per acre – 16′ x 16′ = 170 trees per acre. You can determine which spacing works best for you by the size equipment you have to keep your plantation mowed and fully maintained.

What is the recommended control procedures for killing a tree?

Large trees. Make stem injections using Arsenal AC* or a glyphosate herbicide in dilutions and cut spacings specified on the herbicide label (anytime except March and April). For felled trees, apply these herbicides to stem and stump tops immediately after cutting. Saplings. Apply Garlon 4 as a 20-percent solution in commercially available basal oil, diesel fuel, or kerosene (2.5 quarts per 3-gallon mix) with a peretrant (check with herbicide distributor) to young bark as a basal spray. Resprouts and seedlings. Thoroughly wet all leaves with one of the following herbicides in water with a serfactant (July to October): Arsenal AC* as a 1-percent solution (4 ounces per 3-gallon mix); a glyphosate herbicide, Garlon 3A, or Garlon 4 as a 2-percent solution (8 ounces per 3-gallon mix).

Are Paulownia toxic to animals?

Paulownia is very high in protein and safe for animals. However you will need to protect the trees with fencing from the horses or cattle until the tree reaches a good height so the animals do not destroy the growth of the tree by eating the terminal bud out.

What is the lifespan of Paulownia?

Paulownia is one of the oldest recorded trees in China. The USA has some Paulownia that dates over 200 years old.

Is Paulownia an evergreen?

Paulownia is a hardwood tree and is deciduous.

How much water does Paulownia require?

Paulownia will not tolerate over watering. They like to dry out, then have a drink. If you continuously water every day and keep the root system too wet you will drown the tree. Signs of too much water include leaves that shrivel and turn brown.

I have a deer and insect problem, what do I need to do?

Deer like to feed on short grasses or tasty feed plots. If you do not keep your grasses mowed or have feed plots planted, then you will encounter problems. Deer will only browse on Paulownia if they have nothing else to eat. Some successful ways of detracting deer have been reported. Scatter human hair around the fields, use the common product called “Deer Away”, drill a hole in smelly soap bars and hang them on fence lines, spray your trees with hot sauce.

Deer Deterrent Formula – For 1 Gallon – 1/2 cup of milk, 1 egg beaten, 1 tablespoon of cooking oil, 1 tablespoon of dishwashing detergent, mix with one gallon jug of water. For 5 gallons everything is 5 times more, etc. This should last for 2 weeks.

Caterpillars love Paulownia leaves. The main leaves to protect during the growing season is the terminal bud at the top of the tree. Remember the terminal bud promotes the height and future growth of the tree. Treat the caterpillars with Sevin dust or spray – the same used on tomatoes.

What herbicides can I use for the grasses?

Roundup cannot be used. Paulownia has a very vigorous root system and will uptake nutrients along with herbicides very quickly. Roundup will kill your seedlings or maturing trees very quickly. Gramoxone and Fusilade are proven safe for the Paulownia however it is only a contact herbicide and only controls grasses for a short amount of time.

What is the highest altitude my trees can withstand?

Paulownia will not tolerate an altitude higher than 2200 feet for successful fast growth during one season.

If I plant several acres of Paulownia, where is the market?
