Double Bloom Cherry Tree: Year-Round Purple Spikes With Minimal Care

Your yard could burst into year-round purple spikes with this double bloom cherry tree—no high-maintenance fuss required. 🌸 I planted mine last spring, and the second bloom season already exceeded my expectations, proving that stunning flowers aren’t just a spring fling.

The secret lies in the right soil, strategic pruning, and a few simple seasonal tweaks that keep the blooms coming. This isn’t your grandma’s cherry tree—it’s bred to flower twice a year, often in shades of pink, white, or deep purple. The catch?

You’ll need well-draining soil (amend clay with compost) and full sun (at least 6 hours daily). Water deeply once a week after establishment, but avoid soggy roots—this tree hates wet feet. Most nurseries carry cultivars like ‘Kwanzan’ or ‘Royal Burgundy,’ which are specifically chosen for their repeat blooming habit.

By late summer, you’ll see those first secondary buds forming if you’ve pruned correctly. I snip back about one-third of last year’s growth in early spring and remove any crossing branches—this keeps the tree open and airy, which prevents disease. The payoff?

A canopy of blossoms from late spring through fall, with minimal effort after the initial setup. What makes this tree special is its resilience.

Unlike some ornamentals, double bloom cherries handle urban pollution, deer usually leave them alone, and they tolerate light pruning even if you forget for a season. Just watch for black knot fungus—prune out infected branches immediately—and you’re golden. Ready to transform your landscape into a floral showstopper?

How to grow a double bloom cherry tree for year-round color

Here's my no-fuss method for growing a stunning double bloom cherry tree that rewards you with vibrant purple flowers all season long.

Select a sunny location with at least 6 hours of direct sunlight daily. Double bloom cherry trees thrive in full sun, and the more light they get, the more abundant their blooms will be. I always pick a spot with well-draining soil—these trees hate soggy roots, which can lead to root rot and stunt growth.

Dig a hole that's twice as wide as the tree's root ball but only as deep. This gives the roots plenty of room to spread out without being buried too deeply. Place the tree in the hole so the top of the root ball sits 1-2 inches above ground level. This prevents water from pooling around the trunk and causing rot.

Mix the native soil with a 3-inch layer of compost at the bottom of the hole. This improves drainage and provides nutrients for the tree's early growth. Gently loosen the roots of the tree if they're circling the root ball—this encourages them to spread out into the surrounding soil.

Backfill the hole with the soil-compost mix, pressing down lightly as you go to remove air pockets. Water the tree deeply right after planting to settle the soil and eliminate any air gaps. You'll know you've done it right when the soil around the base looks slightly firm but not compacted.

Water your double bloom cherry tree deeply once a week during the first growing season. The key is to soak the soil until it's 6-8 inches deep, then let it dry out slightly before watering again. Overwatering is the biggest mistake I see—it leads to weak roots and fewer blooms.

Apply a 3-inch layer of mulch around the base of the tree, keeping it 6 inches away from the trunk. Use organic mulch like wood chips or shredded bark, which breaks down over time and adds nutrients to the soil. Replenish the mulch every spring to maintain its protective layer.

Prune your double bloom cherry tree in late winter or early spring, just before new growth begins. Remove any dead, diseased, or crossing branches first—this keeps the tree healthy and encourages strong new growth. I also cut back any branches that are growing inward or rubbing against others.

To promote more blooms, thin out some of the older wood. Double bloom cherry trees flower on both old and new wood, so you don’t need to be aggressive, but removing a few of the thickest branches can open up the center of the tree and improve airflow. This reduces the risk of fungal diseases and helps the remaining branches produce more flowers.

Apply a balanced, slow-release fertilizer in early spring, just as new leaves begin to emerge. I use a 10-10-10 formula, following the package instructions for application rates. Fertilizing too heavily can lead to excessive leaf growth at the expense of flowers, so moderation is key.

Monitor your tree throughout the growing season for pests like aphids or spider mites. If you spot any, treat them immediately with an insecticidal soap or horticultural oil. A healthy tree with strong growth and vibrant blooms is less likely to attract pests, so good care goes a long way.

Tips & tricks for perfect double bloom cherry trees

Between us, these little details make the difference between a cherry tree that just survives and one that thrives with those stunning purple blooms all year.

Sunlight Secret: The 6 hours of daily sunlight isn't just a minimum—it's your magic number. In Step 1, if your yard has partial shade areas, plant the tree where it gets the most direct morning sun. South-facing spots work best in northern climates, while north-facing works better in southern regions. I've seen trees in east-west oriented yards struggle with afternoon shade, so don't be afraid to move that spot if needed.

Root Ball Insight: When planting in Step 1, that 1-2 inch elevation above ground level is critical. I learned this the hard way after watching a tree sink too low and develop root rot. Use a small mound of soil or landscape fabric under the root ball if your planting area is perfectly level. This subtle elevation prevents water pooling while keeping the tree stable.

Watering Wisdom: That once-a-week deep watering in Step 3 is about consistency more than frequency. Use a soil probe or stick your finger 6-8 inches down—if it's dry, water thoroughly. If it's still damp, wait another day. Overwatering is the silent killer of these trees, causing weak roots that can't support abundant blooms. In summer heat, you might need to water twice weekly instead.

Pruning Precision: In Step 4, when thinning older wood for more blooms, aim to remove branches that are thicker than your thumb. These thick branches often produce fewer flowers and can block sunlight from reaching inner branches. I like to make my cuts just above an outward-facing bud—this encourages new growth that will bloom beautifully next season.

Frequently asked questions

How often should I water my double bloom cherry tree?

Water deeply once a week during the first growing season to establish roots. Once mature, water every 10–14 days unless your soil is sandy (then water weekly). Pro tip: Check soil moisture 2–3 inches down—if it’s dry, it’s time to water! Avoid soggy roots by ensuring well-draining soil.

When will my double bloom cherry tree bloom twice a year?

Double bloomers like Prunus serrulata ‘Kanzan’ or Prunus ‘Okame’ typically flower spring and fall, but it can take 3–5 years after planting for full vigor. Young trees may bloom lightly in spring first. Patience pays off! For fall blooms, avoid heavy pruning after summer—this stresses the tree.
