General Plant Information
Mature Size and Form
Plant most fruit trees about 10 – 15 feet apart. Some varieties like Figs, Pomegranates, and Mulberries can grow larger quickly.
Planning is the most important step when planting a tree. Plant your tree where it has enough space to grow to its full potential. Otherwise, your tree will grow into your surrounding trees. A tree that can grow taller with faster growth will overshadow nearby trees. You may need to move other trees to allow for the one that is thriving rather than cutting back one that naturally grows fast and tall.

Plant Care Information
How To Water - Frequency and Duration to Irrigate
Irrigation Water Quantity and frequency based on tree maturity – Fully saturate the soil with water once per week during the early spring. Increase to twice per week as the weather warms. Water 3 times per week or more during hot summers. Provide about 5 gallons of water for a 5 gallons size plant, 15 gallons of water for a #15 size container plant, and 25 gallons for a #25 depending on soil type. Sandy soils can hold less water required more frequently, while clay soils can hold more water and require less frequent irrigation. Young trees with less developed roots require water more frequently while mature plants with developed roots will require less frequent watering.
Fertilizer and Plant Nutrition
Fertilize your tree every 3-4 months. Use a complete balance fertilizer with a 1-1-1 or 2-1-1 NPK ratio during the Spring and Summer growing season, and a formula with more phosphorus and potassium before the tree flowers to improve fruit production and development.
Winter Pruning and Summer Thinning
Prune your tree to allow light into its center for proper growth and fruit production.
Prune fruit trees in the Winter to maintain size and shape to prepare for Spring growth. Thin the tree in the Summer, and remove excessive fruits. Remove any dry twigs and branches. Cut off any new growth below the graft or very low in the tree, this will direct the plant’s energy to its main branches. Thin your trees during the Spring and Summer seasons to ensure the plant’s energy is directed as desired. Harvest ripe fruit to prevent undesired pests.
Harvesting and Pest Management
The basics of integrated pest management is cleanliness and the use of a combination of methods. This means we use an organic pesticide when the pest population reaches a threshold that requires action. Horticultural oils such as Neem oil is an organic pesticide that controls tiny, soft bodied insects. Use organic Bordeaux and Liqui-cop to manage fungus causing diseases such as powdery mildew, rust, and leaf-curls.
Keep a clean environment, free of weeds and dropped fruit that host insects or attract animals. Harvest when fruit reaches size and store indoors. Use repellants and bird netting to protect your harvest from other animals.
Sun Exposure: Full Sun
Deciduous trees need about 5 hours of direct sunlight for proper growth and fruit production.
Sunlight Sensitive plants like Cherries, Persimmons, and Plums can burn in hot climates if they lack water. Use afternoon shade to prevent this damage. A lack of light will stunt growth; balance is key.
Limited Guarantee and Returns
The two factors that determine if a deciduous fruit trees will grow well and produce fruit in a certain area are the Chill Hour Requirement and the Cold Hardiness. “Chill hours” are the amount of cold a deciduous fruit tree need to produce fruit. This is measured in the number of hours below 45 degrees Fahrenheit a plant must experience during its winter dormancy. Paradise Nursery only grows Low Chill fruit trees that meet the chill requirements of all areas of the United States.
The second factor is Cold Hardiness. Cold Hardiness refers to the minimum temperature a plant can tolerate. The USDA’s Cold Hardiness Zones indicate the average minimum winter temperatures of areas. Based on the shipping zipcode, our website will only allow you to add plants to your cart that grow within your USDA Hardiness Zone, and tolerate your climate.
Pollination & Propagation
(Grafting/Cutting) Most of Paradise Nursery’s edible plants are self-fruitful. Self-pollinating trees do not require an additional tree to produce fruit. For your convenience, we have indicated which trees require a pollinator, and their associated pollinators. Only the sweet cherries, avocados, and some plums require a pollinator. All of our other propagated edible plants do not require a pollinator. All of our edible plants are either grown from cuttings, budded, or grafted. This way, we can ensure that our plants are high quality and fruit immediately. Plants will generally begin fruiting within a year of planting.
