About Annual Geranium
Sometimes browsed, which surprises people who bought it as deer-resistant bedding. The scented-leaf zonal pelargonium is aromatic enough to put most deer off, but under pressure it gets eaten. The confusion is in the name. What everyone calls a geranium is Pelargonium, a tender South African plant grown as summer bedding. True hardy Geranium, the cranesbills, is a different genus entirely, perennial to zone 3 or 4, and considerably more deer-resistant. If you want the reliable version, ask for cranesbill or hardy geranium by name. Bloody cranesbill and the Rozanne types are ignored almost completely and come back every year. Pelargoniums overwinter indoors easily if you cut them back hard and keep them nearly dry.

Whether this survives comes down to local pressure, so it is worth knowing the options before it gets browsed rather than after.
- How tall a deer fence needs to beEight feet, and six is the most common expensive mistake in deer fencing.
- Repellent that actually worksThe egg-based recipe that reproduces the active ingredient in the commercial sprays that win university trials.
- Fencing a raised bedA deer jumps from ground level, so measure the barrier from the ground and not from the top of the bed.
- Check it is actually deerDeer tear and leave a ragged stub. A clean 45-degree cut is rabbits, and slug holes get blamed on deer constantly.
