How to Grow and Care for Olive Trees

Olive trees are a beautiful and low-maintenance addition to any lawn or landscape. They have a unique, twisted shape that adds interest to any setting. Once established, olive trees are drought tolerant and require very little care.

Botanical Name: Olea europaea

Light

Olive trees need a lot of sunlight to grow well. A good spot for an olive tree is in a place that gets at least six to eight hours of direct sunlight each day.

  • Olive trees are native to the Mediterranean region, where they receive plenty of sunlight.
  • Olive trees can tolerate some shade, but they will not grow as well if they do not receive enough sunlight.
  • Too much shade can cause the olive tree to develop weak branches and sparse foliage.
  • If you are planting an olive tree in a shady spot, you may need to supplement with artificial light.

Soil

Olive trees are tolerant of a wide range of soil types, but they need well-draining soil to thrive. The best soil for olive trees is a sandy or rocky blend that allows water to drain quickly. You can improve the drainage of any soil by mixing in perlite or gravel.

  • Olive trees are native to the Mediterranean region, where they grow in sandy, rocky soil.
  • Olive trees do not like wet soil, as this can lead to root rot.
  • If you are planting an olive tree in a clay soil, you should amend the soil with sand or gravel to improve drainage.
  • You should also avoid planting an olive tree in a low-lying area where water can pool.

Water

Olive trees are drought-tolerant, but they need some water when they establish themselves and and a bit more during hot, dry weather. Water the tree at its base and roots, to avoid damaging its delicate leaves. Browning leaves and leaf drop are usually caused by either too much or too little water. If you are growing your tree in a pot, make sure it has good drainage. A clay or terracotta pot will help to improve drainage.

  • Newly planted olive trees should be watered deeply once a week for the first year.
  • Established olive trees can be watered less often, but they should still receive at least 1 inch of water per week during hot, dry weather.
  • Water the tree deeply, so that the water reaches the roots.
  • Avoid watering the leaves, as this can cause them to brown and drop.
  • If you are growing your tree in a container, make sure the pot has drainage holes.
  • You can also help to improve drainage by adding perlite or gravel to the potting mix.

Temperature and Humidity

Olive trees are hardy plants that can tolerate a wide range of temperatures. They can withstand desert heat and short-term frost, but they should not be kept at temperatures below -9 degrees Celsius for extended periods of time. Olive trees thrive in hot, dry summers and mild winters.

Olive trees are native to the Mediterranean region, where they experience hot, dry summers and mild winters.

  • Olive trees can tolerate temperatures up to 40 degrees Celsius and down to -9 degrees Celsius.
  • However, olive trees should not be kept at temperatures below -9 degrees Celsius for extended periods of time, as this can damage the tree.
  • If you live in an area with cold winters, you may need to protect your olive tree from frost.
  • You can do this by wrapping the tree in burlap or covering it with a tarp.

Fertilizer

While your olive tree is young, it is beneficial to fertilize it with a high-nitrogen fertilizer in the spring to encourage new, healthy growth.

Nitrogen is an essential nutrient for plant growth, and it is especially important for young plants. A high-nitrogen fertilizer will help your olive tree to grow quickly and develop a strong root system.

  • When to fertilize: Olive trees should be fertilized in the spring, when they are actively growing.
  • What kind of fertilizer to use: A high-nitrogen fertilizer is best for young olive trees. You can find high-nitrogen fertilizers at most garden centers.
  • How much fertilizer to use: Follow the directions on the fertilizer label.
  • How to apply fertilizer: Spread the fertilizer evenly around the base of the tree. Be sure to water the fertilizer in well.
