Can You Grow A Cherry Tree From Store-Bought Cherries: Pit Viability Test and Step-by-Step Guide

Growing cherry trees from store-bought pits is more of a long-term experiment than a guaranteed gardening project. 🌱 The key challenge lies in the hybridization process used by commercial growers, which often renders the seeds sterile.

Even if a pit germinates, the resulting tree may produce fruit that's completely different from the parent variety—sometimes even inedible. I recommend starting with 10-15 pits to increase your odds, as germination rates can be as low as 10% for store-bought cherries.

Before planting, you'll need to perform a simple viability test by soaking pits in water for 24 hours. Viable pits will sink, while non-viable ones will float. Once you've identified potential candidates, they'll require a cold stratification period of 60-90 days in moist sand or peat moss to break dormancy.

This mimics winter conditions and significantly improves germination rates.

How to test cherry pit germination success rates

The first critical step in growing a cherry tree from store-bought fruit is understanding why most pits fail to sprout. Commercial cherry varieties undergo extensive hybridization to improve traits like disease resistance, fruit size, and flavor.

This process often creates sterile seeds that won't germinate, or produces trees that bear fruit completely different from the parent. Even when viable, cherry pits have a 60-80% dormancy rate due to their hard outer shell and internal chemical inhibitors that prevent premature sprouting.

To test pit viability, start with a simple water float test that takes just 24 hours. Fill a glass with room-temperature water and add your cherry pits. After one day, remove any pits that float—they're non-viable.

Viable pits will sink to the bottom due to their higher density from stored nutrients. For best results, test 10-15 pits since store-bought cherries typically show only 10-30% germination success. I've found that sweet cherries (like Bing or Rainier) have slightly better germination rates than tart varieties.

The science behind this test reveals that viable pits contain 20-30% moisture content and intact embryos, while non-viable ones either lack embryos or have been damaged during processing. After identifying viable candidates, you'll need to break their dormancy through stratification—a process that mimics winter conditions.

Place the pits in a moistened paper towel or sand-peat mix (equal parts) inside a sealed container, then refrigerate for 60-90 days at 34-40°F. This cold treatment triggers hormonal changes that prepare the embryo for germination.

Environmental factors during stratification are crucial. The mix should stay consistently moist (like a damp sponge) but never waterlogged, as excess moisture causes rot. I recommend checking moisture levels weekly by squeezing the mix—it should feel like a wrung-out dishcloth.

Temperature fluctuations above 45°F can break dormancy prematurely, while below 30°F may damage the embryo. This precise balance is why professional growers use climate-controlled cold rooms for seed storage.

Once stratified, transfer the pits to a well-draining potting mix in small pots and place them in a warm (65-75°F) location with indirect light. Germination typically occurs within 2-6 weeks, though some stubborn pits may take up to 3 months.

The first sign of life is usually a small root emerging from the pit's bottom, followed by a tiny shoot breaking through the shell. This delicate stage requires gentle watering (never soaking) to prevent fungal infections.

What most people don't realize is that even successfully germinated cherry seedlings may take 5-7 years to bear fruit, and the fruit quality is rarely identical to the parent variety.

The tree's genetics are essentially a genetic roll of the dice—you might get a tree that produces small, tart cherries or even inedible fruit. This is why commercial growers use grafting instead of seed propagation to maintain consistent varieties.

For those committed to the experiment, maintaining a detailed germination journal helps track patterns. Note the cherry variety, pit source, stratification duration, and germination timeline. Over time, you might identify which store-bought varieties have higher viability rates in your climate.

The most rewarding part? Watching those first true leaves unfurl—proof that nature's persistence can overcome commercial breeding's challenges. 🌱

Step-by-step guide to planting and caring for cherry tree seedlings

Once your cherry pits have successfully sprouted, timing becomes critical for transplanting. The best time to move seedlings outdoors is during the last spring frost when soil temperatures reach at least 60°F.

I recommend hardening off seedlings gradually over 7-10 days by placing them in a sheltered outdoor spot for increasing durations each day. This helps them adjust to sunlight and temperature fluctuations without shock.

For container-grown seedlings, choose a well-draining potting mix with added compost to provide essential nutrients during their first growing season.

When planting outdoors, select a location with full sun exposure (6-8 hours daily) and well-draining soil with a pH between 6.0-7.0. Cherry trees thrive in slightly acidic to neutral soil, so test your soil before planting.

Dig a hole twice as wide as the root ball but only as deep as the container's height. Gently remove the seedling from its container, loosen any circling roots, and place it in the hole so the top of the root ball sits just below soil level.

Backfill with native soil and water thoroughly to eliminate air pockets.

Watering is the most common mistake with young cherry seedlings. They need 1-2 inches of water per week, but avoid overwatering, which can lead to root rot. I recommend using a drip irrigation system or soaker hose to deliver water directly to the root zone while keeping foliage dry.

Mulch around the base with 2-3 inches of organic mulch (like wood chips) to retain moisture and suppress weeds, but keep mulch 3 inches away from the trunk to prevent rot. Fertilize lightly in spring with a balanced 10-10-10 formula to support early growth.

Pruning plays a crucial role in establishing a strong structure. Remove any damaged or crossing branches during the first year, and aim to create an open-center form that allows sunlight to reach the center of the tree.

In their second and third years, focus on removing water sprouts (fast-growing vertical shoots) and suckers (shoots from the base). Cherry trees are susceptible to silver leaf disease, so sterilize your pruning tools with rubbing alcohol between cuts.

Regular pruning also improves air circulation, reducing the risk of fungal infections that can plague young trees.

Patience is key with cherry trees grown from seed. While grafted trees can bear fruit in 3-5 years, seed-grown varieties often take 5-7 years or longer. During this time, protect young trees from pests like aphids and Japanese beetles with neem oil sprays.

Monitor for signs of bacterial canker or leaf spot diseases, which are common in cherry trees. If you notice oozing cankers or dark spots on leaves, prune affected areas immediately and dispose of infected material in sealed bags.
