This weeping dissectum form will rarely grow taller than 2 meters tall with a 2-4 meter spread. Most take on a densely branched mounded form perfect adds grace to any garden from patios to large estates. In my experience growing Japanese maples from seed, dissectums come true from seed 80% of the time. Don't prune except to remove dead or damaged material or making a bonsai. Protect roots of outdoor potted plants from extreme winter freezing.
Easy to grow from seed, but growth can be slow for the first couple of years as it puts down its roots. Growth can exceed 30 cm after the third year. Suitable for containers and bonsai. Red leaf types tolerate sun better than green leafed types. Keep soil moist as all Japanese maples do not tolerate drought well (leads to branch loss; also reduces winter hardiness).
Seed will be cold moist stored upon collection as seed looses viability when dry. Soak seed in tepid water 12-24 hours if it sinks, sow immediately. Sow 6 mm deep; tamp soil. Cold strafify for 60-120 days. Expose seed to spring conditions to promote germination. Exposure to direct light not critical. Protect seed/seedlings from varmits. I prick out seedlings when dormant and grow in pots for first 2-3 years for best results. Dissectum types may take 2 years of repeat cycles of warm/cold to germinate so don't toss the pot. Never let seed migrate to soil surface as sun and frost exposure will kill embryo.
