If you are prepared to water consistently to get the tree established then you can plant now, but will need to be very vigilant on watering. Feed the tree with Tui Organic Seaweed Plant Tonic for a few weeks before transplanting and continue after it is planted to help prevent transplant shock. Hi there, we have an avocado in a pot that is about 6 month old, when is it ready to be transplant in to the open soil? Thank you. Hi Alex, avocado trees are frost tender, and require a sheltered free draining position.
You can plant your avocado seedling out now, spring is a good time to plant, as long as you don't have any late frosts and the tree is hardened off before planting, if it has been growing inside.
When the seedling has several leaves and thick roots, plant the seed in potting soil in a inch-wide pot that has drainage holes. Do not add gravel, chunks of broken terra cotta, or other material to the bottom of the pot; they'll hold too much moisture.
Leave the top half of the seed exposed above the soil line. Water the soil until water runs out of the bottom of the pot. Don't let the pot sit in a saucer of water; too much water can rot the roots and cause the leaves to turn yellow. Water deeply whenever the soil feels dry to the touch up to your first knuckle.
If your plant has yellow leaves and wet soil, you are overwatering. Allow the soil to dry out between waterings. Water more frequently when the plant is kept outside in warm, dry weather. Keep young potted avocado trees in partial shade; the leaves can sunburn if they get too much direct sun while they're still getting established.
Prune the tree regularly. Every time it grows another 6 inches tall, cut back the top two sets of leaves. When the plant reaches 12 inches, cut it back to 6 inches. When it reaches 18 inches, cut it back to 12 inches, and so forth.
This encourages bushier growth. As the tree grows, gently remove it and place it in successively larger pots, going up in diameter two inches at a time. In summer, fertilize weekly with a fertilizer with nitrogen , indicated by a higher first number, such as After planting, water it well and place your tree in the brightest light your home allows. Like many citrus trees , avocado trees grow very well grown indoors.
Natural terra cotta is an excellent choice for pots because the porous clay allows air and moisture to move through soil easily. Start with a 6- to 8-inch-diameter pot, with good drainage holes. You can transplant to larger pots as your tree grows over the years. Avocados are tropical plants; they tolerate very little cold. If you live where temperatures rarely drop to freezing — such as the southernmost regions of Florida, Texas, Arizona or California — you can plant your sprouted seed or a nursery-grown tree outdoors.
Choose a site with full sun and excellent drainage, protected from winds and frost. Allow plenty of room for the tree's mature size. Containers restrict plant size, but avocados can grow 40 feet tall or more in the ground. Avoid planting avocados too deep. Once established, avocados are simple to care for. Their large, leathery, green leaves and attractive form make them beautiful houseplants and landscape trees, even when they're fruitless. By providing your tree's basic needs, you help ensure its beauty and future productivity.
Watering - Avocado roots need plenty of air, so avoid overwatering. Always let container soil dry out slightly, then water thoroughly to moisten the entire root ball. If your container tree moves outdoors for summer, it may need daily watering. Container plants dry out more quickly in sun and wind — and don't forget to bring your plant indoors once temperatures drop below 50 degrees Fahrenheit in fall. For landscape avocados, water the entire area beneath the tree's canopy.
Water deeply and thoroughly, then allow the soil to dry out slightly before you water again. You should see the roots and stem start to sprout in about two to six weeks. When the stem is 6 to 7 inches long, cut it back to about 3 inches. Water it frequently, with an occasional deep soak.
The soil should be moist but not saturated. If the plant turns yellow, you may be over-watering; let it dry out for a few days. If the leaves turn brown and fry at the tips, too much salt has accumulated in the soil.
Let water run freely into the pot, and drain it for several minutes. When the stem is 12 inches high, cut it back to 6 inches to encourage the growth of new shoots. Remember that avocado trees do best at moderately warm temperatures 60 F to 85 F with moderate humidity. They can tolerate temperatures, once established, of around 28 F to 32 F with minimal damage. Avoid freezing temperatures.
Plant your tree in March through June. Plant it in a non-lawn area and away from sidewalks and, if you can, plant it in a spot protected from wind and frost.
Remember, full sun is best. Dig a hole as deep as the current root ball and just as wide as the width plus a little extra so you can get your hands into the hole to plant it. The avocado is a shallow-rooted tree with most of its feeder roots in the top 6 inches of soil, so give it good aeration.
Its root system is very sensitive, and great care should be taken not to disturb it when transplanting. If the tree is root-bound, however, loosen up the soil around the edges and clip the roots that are going in circles.
If you have a heavy clay soil, elevate the tree in a mound for better drainage. Make the mound 1 to 2 feet high and 3 to 5 feet around. The sooner the roots get into the bulk soil, the better the tree will do. Trees typically need to be watered two to three times a week. As the roots reach out into the bulk soil, more water can be applied and the frequency of watering can diminish to about once a week after a year.
When watering the tree, soak the soil well, and then allow it to dry out somewhat before watering again. The rule of thumb for mature trees is about 20 gallons of water a day during the irrigation season. Seedlings will require quite a bit less water, of course.
Check the soil before watering each time to make sure it has dried somewhat. If the soil from around the roots can hold the impression of a hand when squeezed, it has enough water. Mulch with coarse yard mulch.
