A new gardener seeks a trustworthy plant care resource and help with two weeping willows planted simultaneously—one thriving, one with immediate yellow/brown leaves. The nursery said not to worry if branches aren't crisp.
Best Plant Information Sources
- University Extension websites (search "site:edu [plant name] care") — research-based, region-specific.
- Missouri Botanical Garden Plant Finder — excellent cultural details.
- Lady Bird Johnson Wildflower Center — native plant focus.
- Google Scholar for deep dives — but filter for extension/edu domains.
Avoid generic garden blogs; prioritize .edu, .gov, botanical garden domains.
Diagnosing the Struggling Willow
Scratch test: Scrape bark on a twig with fingernail/knife.
- Green underneath = alive at that point. Work downward until green found; prune dead tips.
- Brown/tan = dead. Continue down to find live tissue.
If the entire stem is brown to the base, the tree is dead—replace it.
Why One Willow Failed
| Possible Cause | Clues |
|---|
| Root ball issues | Circling roots, dry root ball at planting, J-rooting |
| Site difference | Wetter/drier spot, soil compaction, grade change |
| Transplant shock | One had more root loss; willows hate root disturbance |
| Vascular disease | Verticillium wilt — rare but possible |
Weeping Willow Care Basics
- Water: Consistently moist soil—never let dry out first year.
- Fertilizer: Light application of 10-10-10 in early spring only if growth is poor.
- Space: 30+ ft from structures, pipes, septic—aggressive roots.
- Pruning: Late winter; remove crossing, dead, or low branches.
Bottom Line
Use university extension sites for reliable info. Scratch-test the struggling willow; prune to green wood. If no green at base, replace it—willows establish fast when planted right.
