Little Ollie olive trees thrive with at least 8 hours of sunlight and require more frequent watering when they are young or newly planted to establish roots.
A common recommendation is to check the top 1/4 inch of soil and water the tree when this layer becomes dry.
-
Young Trees:
- Initial Week: Water every other day.
- Following Weeks: Reduce to twice a week.
-
Mature Trees:
- Cool Seasons: Watering can be reduced accordingly.
- Warm Seasons: Maintain moisture without overwatering.
Adjusting to Rainfall Patterns
The watering needs of Little Ollie must be adjusted with rainfall patterns.
During rainy seasons, one might not need to water the tree as frequently, and excess moisture should be allowed to drain away to prevent root rot.
In drought conditions, watering might need to be increased, especially in areas with waterwise gardening practices.
- Rainy Season: Reduce watering, ensuring proper drainage.
- Dry Season: Increase watering frequency while observing drought-tolerance characteristics.
Container Watering
When Little Ollie is grown in a container, it requires more careful monitoring of moisture levels due to less soil volume which can dry out or become waterlogged quickly.
- Drainage: Ensure containers have adequate drainage holes.
- Frequency: Check soil more frequently, as containers dry out faster than ground soil.
- Amount: Water until it runs out of the bottom, ensuring the roots have sufficient moisture.
Nutrition and Fertilization
Proper nutrition and fertilization are paramount for the health and optimal growth rate of Little Ollie olive trees. The tree's roots absorb essential nutrients from the soil, which are crucial for vitality and development.
Fertilizer Types and Application
When fertilizing a Little Ollie, gardeners should opt for a general-purpose fertilizer that balances nitrogen, phosphorus, and potassium. Recommended compositions include:
- Granular Fertilizers: Apply evenly around the base, avoiding direct contact with the trunk.
- Liquid Fertilizers: Dilute as directed and water the soil at the base of the tree.
The gardener should ensure that the fertilizer is distributed in the tree's root zone but not applied too close to the trunk to prevent root burn.
Fertilizer Frequency
The frequency of fertilization depends on the olive tree's lifecycle and soil richness:
- Young Trees: Fertilize every few months to support rapid growth.
- Established Trees: Fertilize less frequently, typically once in spring and possibly again in fall if the growth rate appears to slow or foliage color pales indicating a nutrient deficiency.
Always follow the specific instructions provided on the fertilizer packaging for application rates and timing to avoid over-fertilization, which can harm the tree.
Pruning and Shaping
Proper pruning and shaping are critical for maintaining the health and aesthetic appeal of a Little Ollie tree. They ensure the tree's foliage remains vibrant, and the structure conforms to desired dimensions or forms, whether as a hedge or a distinct topiary piece.
Pruning Techniques for Size Control
When controlling the size of the Little Ollie, it's recommended to prune back the roots by one-third to one-half when repotting, which typically occurs every two years. This method helps maintain the tree's proportions.
Additionally, selective removal of branches promotes a dense and healthy foliage structure.
The characteristic deep green leaves with silvery undersides are best showcased by maintaining a compact shape, allowing adequate light penetration and air circulation.
Creating a Topiary or Formal Hedge
For a formal hedge or topiary, regular shaping is necessary to achieve and retain the desired artistry of the Little Ollie.
