Frequently Asked Questions
How often should I water my new shrubs during the first summer?
You should aim for deep, thorough watering two to three times a week. Use a slow-trickle method rather than a quick spray to ensure the root ball gets fully saturated.
When is the best time of year to plant shrubs in Houston?
Fall is your best window, usually between October and November. This allows the roots to establish themselves in the cooler soil before the summer heat arrives to stress them out.
Do I need to fertilize my shrubs every spring?
Many established shrubs do not need much help if your soil is decent. Apply a slow-release fertilizer in early spring if you see stunted growth or yellowing leaves, but do not overdo it.
What should I do if my shrubs look wilted after a hot afternoon?
Wilting is often a natural way for plants to conserve moisture during the peak of a 100-degree day. Check the soil moisture first, but resist the urge to water them during the heat of the afternoon.
Can I plant shrubs right against my house foundation?
Keep a gap of at least two to three feet between the foundation and the shrub. This promotes proper airflow and prevents moisture issues from damaging your home exterior.
