How to Plant California Lilac Hedge

If you're ready to plant a California lilac hedge, follow these steps:

Choosing the Right Location

Choosing the right location is crucial for the success of your California lilac hedge. Here are a few things to consider:

• Sunlight: California lilac needs full sunlight to thrive, so choose a location that receives at least 6 hours of direct sunlight per day.
• Soil: California lilac prefers well-drained soil and can adapt to most soil types. However, it's essential to ensure the soil is not too acidic or alkaline.
• Space: California lilac can grow up to 10 feet high and 10 feet wide, so make sure you have enough space to accommodate its size.

Preparing the Soil

Once you've selected the right location, you need to prepare the soil. Here's what you need to do:

• Test the soil: Use a soil test kit to determine the pH level of your soil.

When planting your California lilac hedge, spacing is critical. Follow these guidelines:
