Where it Grows
Planting
When to Plant
Peach trees are best planted in the spring or fall, after the danger of frost has passed but before the growing season begins.
How to Plant
- Site Selection: Choose a location with full sun and well-drained soil.
- Soil Preparation: Amend soil with compost to improve fertility and drainage.
- Planting: Dig a hole twice as wide as the root ball and just as deep. Place the tree in the hole and backfill with soil, ensuring the graft point is at soil level.
Planting Calendar
- Plant outdoors: 2–6 weeks before the last frost
- Autumn planting: 4–8 weeks before the first autumn frost
- Plant out: Feb 27 – Apr 2
- Autumn planting: Aug 30 – Oct 3
Care
Watering
Water peach trees deeply once a week, more frequently during dry spells. Ensure the soil is moist but not waterlogged.
Weeding
Keep the area around the peach tree free of weeds, as they compete for nutrients and water. Use mulch to suppress weed growth.
Mulching
Apply a 2-4 inch layer of organic mulch to retain moisture, regulate temperature, and suppress weeds.
Fertilizing
Fertilize peach trees in early spring with a balanced fertilizer, following package instructions for quantities based on tree age.
Thinning
Thin fruit when they are about the size of a marble, leaving 6-8 inches (15-20 cm) between each fruit to promote larger fruit size.
Pest Management
Monitor for common pests such as aphids and peach tree borers. Use insecticidal soap or pheromone traps as needed.
Harvesting
Harvest peaches when they are slightly soft to the touch and their color has fully developed, typically in mid to late summer.
Growing in Containers
Grows well in a pot of at least 60 litres (16 US gallons), with drainage holes. Best kept outdoors.
Propagation
By grafting
- Obtain a healthy peach-compatible rootstock and a dormant scion from the desired variety.
- Make matching cuts on the rootstock and scion in late winter or early spring.
- Join the cut surfaces, aligning the cambium on at least one side.
- Bind and seal the graft.
- Remove shoots that emerge below the graft union.
From seed
- Remove a pit from a ripe peach and clean off the flesh.
- Chill the pit in a moist medium for about 8–12 weeks.
- Sow it in well-drained potting mix after chilling.
- Keep the mix moist until the seedling emerges.
- Graft the desired variety onto the seedling later if you need fruit true to that variety.
Companion Plants
Good neighbors
- White clover: In established orchards, it provides a low-growing, nitrogen-fixing groundcover that supports beneficial insects; keep it clear of the trunk.
Keep apart from
- Tomatoes: Tomatoes can harbor Verticillium wilt in soil, which can also infect peach trees.
- Potatoes: Potatoes can harbor Verticillium wilt in soil, which can also infect peach trees.
- Lawn grass: Grass growing beneath a peach tree competes with its shallow roots for water and nutrients.
Common Problems
- Brown rot
- Leaf curl
- Peach scab
- Bacterial spot
Pests and diseases: Peach Leaf Curl, Borers, Bacterial Leaf Spot, Frost Damage, Aphids
