The Steps to Grow Snowball Bushes
Step 1:
Clean the Area- Remove grass and weeds from the planting site.
Dig a Hole- Dig a shallow and broad hole that should be three times the diameter of the root ball. However, the hole should not be deeper than the root ball.
Step 2:
Careful Planting- Remove the snowball bush from its pot and gently loosen the outer roots along the sides and at the bottom. Ensure the roots are not damaged.
Step 3:
Plant the Roots- Now, place the bush in the center of the hole, ensuring the root crown(it is the part of the bush where the trunk meets the roots) is 1.5-2 inches above the ground level. Then fill the hole with the same soil that was removed while digging.
Step 4:
Water the Planting Area- To establish the soil after planting, water it thoroughly. You can also add mulch (about 4 inches deep) or wood chips over the planting area to remove weeds and to retain moisture.
Essential Care and Maintenance Tips for Vibrant Annual Blooms
Once the root is planted, it needs proper care and maintenance to grow well. Here are the caring tips you should follow:
Light
The snowball bush needs at least 6 hours of daily sunlight to produce bunches of flowers when grown in cooler parts of the region. Whereas, if it’s grown in warm weather regions, partial shade is what they need to thrive.
Type of soil
Though it grows in various soil types, it prefers well-drained, loamy soil with a slightly acidic pH.
Watering Frequency
Snowball bushes don't like dry soil, so water them 1 inch weekly to maintain soil moisture. However, if the climate is too warm, water them more. You can also add a layer of mulch around the shrub to retain moisture.
Temperature
This plant can tolerate winter temperatures in zone 6 and summer heat in zone 8, but not beyond these zones. If the plant receives proper air circulation and drainage, it can grow well even in both dry and humid environments.
Feeding
Apply a slow-release fertilizer in spring, or add compost around the plant anytime. Avoid overfeeding because it may affect the plant’s blossoms.
