When to plant apple
- Transplant out: ~-6 weeks after last frost.
Companion plants for apple
Plant with: Chives, Nasturtium, Garlic, Comfrey.
Avoid near: Potato.
Common pests & problems
Codling moth, apple maggot. Bag fruit or use kaolin clay.
Feeding & fertilizer
N-P-K ratio: Balanced 5-5-5, avoid fresh manure
Organic options: Compost mulch every spring · Blood meal + bone meal before flowering · Kelp meal after harvest
When to feed: Base feeding on a soil test and on how much new growth the plant made last year.
Watch for: Lots of leafy growth but little fruit = too much nitrogen.
N = nitrogen (leaves), P = phosphorus (roots and flowers), K = potassium (fruit and disease resistance). How to read a fertilizer label →
Grower's tip
Plant two different cultivars within 50 ft for cross-pollination. Prune to an open-vase shape.

Soil & water for apple
Soil & pH
6.0-7.0 for most; confirm with a soil test
Deep, well-drained soil. Standing water around the roots causes root and crown rot.
Test soil before planting and correct pH then. Mulch with compost each spring, kept a few inches off the stem or trunk.
Watering
1-1.5 in / week; 2 in during fruit swell
Drip or soaker at the root zone. Keeping leaves and fruit dry lowers fungal disease.
Check soil 6 in down; water when it is dry there. Drought while fruit is sizing gives small fruit.
Knowing when to harvest
- Fruit twist-and-lifts cleanly from the spur.
- Seed color turns brown from white. The reliable ripeness test.
- Ground color (background under the red blush) shifts from green to cream.
Storing & keeping
Cool (32-40°F), high humidity, dark. Storage varieties keep 4-6 months. Never store with bananas.
What to expect
Per plant: 50-150 lb semi-dwarf, mature
Troubleshooting apple
Every fruit tunneled
Likely cause: Codling moth
What to do: Bag individual fruits at thinning, or trap trees with kaolin clay.
Scab (rough dark spots)
Likely cause: Wet spring
What to do: Prune for airflow; plant scab-resistant varieties (Liberty, Enterprise, GoldRush).
Varieties worth the space
Not every name in a seed catalog. These are the ones growers order again, with what each one is actually good at and what it asks of you.
Liberty
Scab-immune, disease-resistant, tart-sweet flavor.
Honeycrisp
Crisp and sweet; needs a pollinator.
GoldRush
Long storage (6+ months), scab-resistant.
Growing apple in containers
Only genetic dwarf varieties; 20+ gallon pot; usually disappointing yield.
Nutrition
Varies by crop: see the crop notes above.
Common questions
Do I need two trees?
Yes for most varieties. Apples need cross-pollination. Choose two varieties with overlapping bloom.
