    All About the Okame Cherry Tree

    This tree was originally bred in England from a cross of Prunus incisa and Prunus campanulata. The breeder, Captain Collingwood Ingram, was trying to create a tree with bright pink flowers, but without the low cold tolerance of the parent plants. I think it’s safe to say that he succeeded!

    Before reaching maturity, it grows in a vase-shaped structure, rounding out as it grows older. The striking pink and white blossoms will add bundles of beauty to your landscape, and they can be planted at any time of the season. Producing masses of candyfloss-pink flowers in early spring, Okame trees are ideal for small gardens or lining driveways. These are strictly ornamental trees and don’t often produce viable fruit.

    If you want a tree that attracts bees like crazy, look no further. Pollinators of all kinds flock to the rosy pink blossoms of this flowering cherry, with flowers lasting up to three weeks in the early spring. It also tends to flower earlier than other varieties of cherry for an earlier spring burst of color.

    When not in bloom, the foliage of these evergreen trees is still beautiful. It remains deep green until late August. At this point, the fall foliage begins turning golden yellow before eventually fading to a deep orange and red. The leaves remain, meaning it’s not a deciduous tree. All year long, the tree dons reddish brown bark that looks great in a landscape.

    You can buy your own bare-root plants or find someone with a tree and propagate from that one. Whatever you decide, you won’t be disappointed.

    Popular in the south, where it’s hot and humid, this tree can also tolerate a moderate to slightly cold climate. In fact, it needs a cold winter to bloom well in late winter and early spring. Grow it if you’re in zones 5 to 9.

    Light & Temperature

    This tree wants full sun. Make sure to plant the tree in a location where it can be seen for your own enjoyment and has access to sunlight. If you live in a colder climate or up north, you should plant it in a location where it gets at least 4 to 6 hours of sunlight.

    If in a hot climate or zones 9+, plant it in an area where it gets a bit of relief from the absolute hottest parts of the day if possible…blossom production will be better this way.


    When it comes to watering, be mindful of the specific climate you live in. If you’re in an area where soil dries up quickly and you don’t get much rain, you have to water much more often. After you plant your tree, water every few days, and after it’s established, water once per week. In times of heavy rain, avoid watering too often.

    Also, add mulch around the base of the tree to avoid early dry-up. You don’t have to water as much if you’re in a colder climate that gets a bit more rain. It’s really an observation game here…pay attention to how your tree is looking and adjust your watering from there.


    Flowering cherry trees can do well in almost any kind of soil. As long as the soil drains well, your tree should grow well. Make sure your soil is moist for healthy growth, though. This hybrid cherry doesn’t do well in overly wet or clay soil, so make sure that you avoid these soil conditions. Loose, fertile, well-draining soil is a good basis to start with. It will adapt to many soil types.

    Fertilizer for the Okame Cherry Tree

    You don’t need to fertilize too often for a cherry tree – once a year is plenty. Give it a low-nitrogen fertilizer early in the spring, so it can use that nutrition throughout the growing season. You can add a little bit of fruit tree fertilizer in place of your low-nitrogen fertilizer for a couple of feedings just before winter arrives. It’s at this time you should avoid fertilizing as your tree is dormant.

    Cherry Tree Propagation

    You can propagate Okame cherry tree using the green and springy cuttings of a branch in late spring and early summer. Remove all but the top two to three sets of leaves, and dip the cutting in rooting hormone. Pot them about 2 to 3 inches deep in containers with soilless planting medium and keep it warm and mildly moist with a plastic bag affixed over the cutting and the top of the container.

    Lightly mist the inside of the bag as the condensation dissipates. You should see new growth in about a month. It’s at that point you can repot into 4 inch containers. You can also graft onto another root stock, but that’s a more complicated process that is best explained in a different guide.

    Pruning Your Okame Cherry Tree

    Pruning is necessary early in your tree’s life if you want to save yourself effort in later trees. Because it’s not a huge tree, some pruning after the blooms fall off will help shape it in years to come. A good pair of Felco 2 Pruners will help with your pruning!

    Here’s a simple process:

    1. After you plant your tree, cut the head to 3′ above the ground and cut all branches back to no more than three buds.
    2. Let new shoots grow to about 10″, then cut below them to help your cherry tree bush out.
    3. Prune off all shoots at the bottom of the tree (known as water sprouts) as well as branches coming from the center of the tree.
    4. Continue to shape your Okame cherry tree as desired for the first 4 years of its life.

    While the Okame cherry tree is resistant to most pests and diseases, there are a few things to look out for. Here are those, along with a couple of growing problems.

    Okame Cherry Growing Problems

    If you plant your tree too deeply, it will be stressed and have less access to water and nutrients that keep it safe from pests and disease. If you just planted it, you can try to remove it and plant it slightly higher with a mound of soil at its base. However, you may have to work around issues that arise if it was planted too deeply a long time ago.

    If you overwater your tree, the soil remains wet long enough to support disease pathogens that can cause root rot and the proliferation of other fungal diseases.


    Over-fertilization is prohibited for cherry blossom trees. It can attract pests to your tree. If you find pests attacking the tree, use a pesticide to get rid of them.

    Aphids, spider mites, and scale insects are common pests of cherry blossom trees. They suck the tree juices as they congregate on your tree. Aphids cause leaf curling and leaf drop. Spider mites cause light yellow stippling on green leaves. Scale insects congregate in slimy brown masses on branches. You can spray aphids and spider mites off the Okame cherry tree with water, or use either insecticidal soap or neem oil to treat. Scale may require applications of horticultural oil in mid spring.

    Cherry borers generally only attack fruit trees when they’re weak or improper nutrition is present. Do not feed your tree with only high-nitrogen fertilizers; instead, feed them regularly with a balanced fertilizer to keep them healthy. Ensure the trees are not dealing with stresses from damage to the trunk, pest pressures, or other causes, as they make trees more susceptible to borer attack. Pyrethrin based bark sprays can prevent them, but the better tactic is to ensure you have a healthy tree that the borers will skip!


    There is a risk of rot and spot in cherry trees. This requires you to water them carefully. Overwatering can spur the growth of the fungi that cause root rot. Ensure your tree has good drainage. This also will prevent some types of crown rot.

    Black knot can occur in some cherry tree species, and while these ornamental cherries are less at risk, there is a rare chance that it could appear. If the fungal gall appears on your tree’s branches, prune affected branches below the gall and remove the infected tissue entirely. Do not compost the pruned material – it’s better to burn it or dispose of it in the trash!

    Powdery mildew happens in humid climates. While it isn’t likely to cause severe harm, it can spread to other plants. Prevent powdery mildew with regular applications of horticultural oil during the cool and damp season. Once temperatures get consistently above 80 degrees, discontinue horticultural oil applications. For leaf spots, you can use a copper fungicide applied in spring every 7 to 10 days until the problem passes.

    Crown galls are a risk, but unfortunately, by the time you diagnose it, it’s already established. This bacterial gall is most common on the trunks of infected trees. While the tree itself may still survive despite its bacterial infection, it can spread to other plants around the tree. There are no treatments for crown gall.
