How to Regrow a Seedless Lemon Tree

Combine equal measures perlite, peat moss and medium-grit sand in a bucket. Drizzle water onto the components while mixing them together. Keep adding water and stirring until the mixture is moderately moist and uniform in appearance.

Pack the growing medium created in Step 1 into a six-inch-deep plastic pot. Leave the top 1/2 inch of the pot empty. Firm the growing medium to squeeze out any air bubbles and even out the surface. Set the pot aside.

Gather a six-inch-long cutting from the seedless lemon tree. Select a leafy, flowerless cutting from the tip of a healthy branch. Make the cut at a 45-degree angle using sharp, clean pruning shears.

Pull off all the leaves from the bottom three inches of the seedless lemon tree cutting. Slice off a 1/4-inch-wide and one-inch-long portion of bark from the base of the cutting. Use the blade of the pruning shears to slice off the bark.

Dip the bottom three inches of the cutting into 0.1-percent IBA rooting hormone powder. Twirl the cutting back and forth to completely coat the bark. Shake the cutting to release any caked-on rooting hormone.

Returning to the pot, poke a three-inch-deep hole into the center of the growing medium. Insert the hormone-treated end of the seedless lemon cutting into the hole. Push the growing medium in against the stem. Firm it very well so the cutting stands upright.

Place the pot on a propagation mat near a large window or inside a greenhouse. Set the temperature on the propagation mat to 70 F to hasten rooting. Turn off the propagation mat at night.

Moisten the growing medium in the pot whenever the top inch dries out. Add just enough water to keep the growing medium moderately moist but not soggy or dripping wet.

Mist the foliage of the seedless lemon tree cutting every other day to keep it hydrated and healthy. Spritz the leaves three or four times with distilled water from a plant mister.

Check for roots 45 to 60 days after potting the seedless lemon tree cutting. Tug on the base of the cutting to feel if it is anchored to the growing medium by roots.

Transplant the seedless lemon tree into a large permanent pot or sunny garden bed three weeks after it roots. Keep the young tree sheltered from extreme temperature fluctuations and strong wind.
