Edible Uses
Edible Parts: Fruit;  Leaves.
Edible Uses:

Fruit - raw or cooked[61, 177]. Sweet and juicy[11, 183], it is very nice in small quantities[K]. Very seedy[105]. The skin is rather tough and unpleasant, but the pulp is delicious with a custard-like texture, it is one of our favourite late summer fruits[K]. The fruit is about 2cm in diameter[200]. Young leaves - cooked[105, 177, 183].

Cultivation details
Landscape Uses:Pest tolerant, Specimen, Woodland garden. An easily grown plant, it succeeds in any soil of good or moderate fertility, from acid to slightly alkaline but dislikes shallow chalky soils[184, 188]. Grows well in heavy clay soils. Prefers a rich well-drained loamy soil and a position that is at least partially sunny[11]. A very ornamental plant[1], it is hardy to about -20°c[184]. A number of named forms have been developed for their ornamental value[182]. Plants are slow-growing when young, they speed up somewhat after a few years but then soon slow down again[202]. The sub-species of C. kousa chinensis grows more freely, flowering and fruiting better in Britain though it barely differs in appearance from the species[11]. This species has been known to hybridize with C. capitata[182]. The cultivar 'Norman Hadden' could be such a hybrid[182]. Plants in this genus are notably resistant to honey fungus[200]. Special Features:Attracts birds, Not North American native, Blooms are very showy.
Propagation
Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[80, 113]. The seed must be separated from the fruit flesh since this contains germination inhibitors[80, 164]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[164]. Scarification may also help as may a period of warm stratification before the cold stratification[80, 164]. Germination, especially of stored seed, can be very slow, taking 18 months or more[164]. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame[188]. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage[78]. Layering of new growth in June/July. Takes 9 months[78].

Can you assist with information relating to possible problems with lack of flower i.e.age before flowering or a physiological condition???

I planted a cornus kousa chinnensis about 4 weeks ago. It has begun to shed its leaves. I had removed an old Viburnum because it suffered from leaf beetle, dug over the soil and added farmyard manure and soil improver. I planted a clematis and a hydrangea at the same time as I planted the dogwood. These are doing well. The dogwood is in part sun with shading at the back from a neighbour's leylandii hedge. I have ensured it has been well-watered. Any suggestions would be gratefully received. John.

I have a japanese dogwood in my yard. I don't know what varity it is. It has leaves in the spring. It buds out but never blooms. At the moment it has no leaves at all. Actually it looks dead. The tree has been planted for 5 years now. What can I do to help it?

My cornus kousa produced so much fruit that it's become a nuisance. There are so many overripe pods dropping on the ground and they are attracting rodents. How can I limit the amount of fruit the trees produce?

Removing flowers is the only way i can think of to reduce the number of fruit since flowers of course become fruit) this also usually means the few remaining fruit will be larger
