Check my stateWhy isn’t my hydrangea blooming?
Winter bud kill, wrong-time pruning, or wrong species. Macrophylla blooms on old wood — pruning it in spring kills the flowers.
How do I keep deer out of my garden?
Honest answer: a 7-foot fence, repellent rotation, or planting things deer ignore. No perennial is deer-proof.
Why are my tomato bottoms turning black?
Blossom end rot. It’s not a disease — it’s a calcium uptake problem from irrigation swings. Sprays don’t fix it.
When should I prune my hydrangea?
Depends on species. Macrophylla and oakleaf right after bloom. Paniculata and arborescens in late winter. Get it wrong and there’s no flower next year.
What plants come back every year?
Perennials in your USDA zone. A “perennial” from zone 9 is an annual in zone 5 — the term needs the zone caveat plant tags often skip.
How do I get rid of Japanese beetles?
Hand-pick into soapy water, milky spore for the lawn, and do not use beetle traps — they attract more beetles than they kill.
The 6-year tool I still use. Replaceable blade, replaceable spring, sharpens cleanly. The one piece of garden gear that pays back every season.
