- Dig a hole as deep as the tree root ball and twice as wide.
- Remove the plant from its container, holding it by the root ball and not the trunk. Set the root ball in the planting hole. The top of the root ball should be level or slightly higher than the surrounding soil. In heavy clay soil, raise the root ball 2 inches above ground for every 10-gallon container size.
- Mix 1 cup gypsum with every 5 gallons of soil removed from the hole. Return the soil as backfill up to the halfway mark of the hole. Spread time-release fertilizer for trees (Agriform pellets) around the tree roots. Add the remaining soil, filling the hole to ground level. Firmly settle the soil to eliminate air pockets.
- Build a water basin around the plant to allow for easy watering for the first year. Water thoroughly once a week, using 5 gallons of water with 1/2 teaspoon of plant growth stimulant. 5 gallons of water are equivalent to 1 inch of rainfall, so adjust your watering to account for weather conditions and water from sprinklers.
- Apply a thick layer (4 feet deep and 2 feet wide) of shredded mulch over the soil area to conserve moisture, discourage weeds, and buffer root temperatures.
- Use a root stimulator (3 1/2 tablespoons per gallon of water) for the first 2 months. This will encourage faster rooting and lessen transplant shock.
Growing Tips for Trees & Shrubs
Water
Each tree and shrub needs 1 to 15 gallons of water once a week. During drought periods or in very sandy soil, water every 5 days. During abnormally wet periods or in very heavy soil, water every 10 to 14 days.
Fertilizer
Use Superthrive with every watering for the first 3 months after planting. Continue feedings once a month for the first year. Feed with Ferti-lome Tree and Shrub Fertilizer after six months, beginning in February or October.
Disease
Watch for lesions or occasional leaf spots. Spray with suitable fungicide, if necessary. If you are unsure about a problem, bring a sample of the affected plant into Anawalt Lumber & Hardware and have one of our nursery professionals assist you.
Weeds & Grass
For the first year, pull or spray with glyphosate under the tree canopy to keep the mulch area clean.
Insects
Watch for holes in leaves or insects gathering at the ends of branches. Treat with an appropriate control measure.
We want to help your tree or shrub grow. If you see any unusual changes in the foliage or branches, please don’t hesitate to call us at Anawalt. Addressing small concerns in the beginning will insure a healthier plant in the future.
FAQ: Planting Trees in SoCal
Q: What are the best tree species to plant in Southern California?
Recommended species for Southern California include the Coast Live Oak, Western Redbud, California Sycamore, and the California Pepper tree. These species are well-adapted to the region’s climate, offering aesthetic appeal and resilience.
Q: How often should trees be watered in the Southern California climate?
In general, newly planted trees require more frequent watering, about twice a week, which can be scaled back to once a week after the first year. Depending on the season and rainfall, mature trees can be watered less frequently.
Q: What’s the optimal season for planting trees in this region?
The best time to plant trees in Southern California is during the fall. This allows the trees to establish their root systems during the cooler months before the dry, hot summer sets in.
Q: Are local regulations or permits required for planting trees in Southern California?
Permits may be required in some areas, especially for specific species or when planting in public spaces or near utility lines. Check with local city or county government offices.
Q: How can I protect my trees from common pests?
Regular monitoring, proper watering, and maintaining tree health are crucial. Environmentally friendly pest control options like beneficial insects or organic pesticides can be effective for certain pests.
Q: What soil amendments are recommended for tree planting in this area?
We recommend compost and mulch to improve soil structure and fertility, ensure better water retention, and provide necessary nutrients for tree growth.
Q: How much space should I allow between newly planted trees?
The spacing depends on the mature size of the tree species. A general rule is to space trees 10 to 20 feet apart to ensure enough room for growth and prevent crowding.
Q: What are the signs of water stress in trees, and how can it be mitigated?
Signs include wilting leaves, yellowing, and premature leaf drop. Mitigation involves adjusting watering schedules, mulching to retain soil moisture, and possibly consulting a tree care specialist.
Q: Which fertilizers are best suited for trees in Southern California?
We recommend a balanced, slow-release fertilizer. Needs may vary depending on the tree species and soil conditions. Consider testing your soil.
Q: How can I ensure my trees are resilient to drought conditions?
Choose drought-tolerant species, mulch around the base of trees to reduce evaporation, and water deeply but infrequently to encourage deep root growth.
