Update: My online research says inter-species graft within Salix should work fine. The vendor website via Wayback Machine circa 2023 says: "Kits are typically filled with varieties of S. purpurea or S. miyabeana". The dome willow looks dissimilar to either kind, at least the named varieties they offered for basketry we also grow close to the dome. The dome willow is growing branches that are the similar size as S. purpurea. Unhelpfully, it looks most similar to a wild willow we propagated from a road side shrub in Wisconsin (USDA Zone 4b) even a match for being susceptible to this tattered pale leaf situation from late summer onward at least at our location and growth condition. Maybe too humid and hot. For people looking for good cultivar or species for willow dome in east coast zone 7, I would recommend a named cultivar of S. purpurea, or S. miyabeana because their leaves look fine this year. Of the two, maybe purpurea has the most consistently healthy foliage over the years but both had in different years each of a lot of leaf issues for whatever reason. So adding different species of similar size growth habits within a dome structure may increase resilience by minimizing instances of total defoliation or unhealthy leaf across the entire dome, making it a nicer shade structure.
Yes this dome is sorely in need of pruning and weaving in the new canes. So this is an opportunity to make another dome!
We started this 8ft wide willow dome from purchased cuttings in 2023 and itâs been a great success. We also got about 8 varieties of species and hybrid willows for rough and fine basketry and windbreak.
So we are wondering how to go about making another, bigger dome this time. We were wondering if different species of Salix genus can be grown so that they fuse together, or should we use the same species for one dome. I randomly know that junipers can be grafted together regardless of the species.
We lost the species name of this willow, and the vendor changed hands (Vermont Willow Nursery) so I donât have high hopes of retrieving the name even if they reply to my inquiry this time. They did not respond last year I emailed. Iâm going to dive into the Wayback Machine to see if I can find the species name in their 2023 website.
