cabin-friendly plants

Alan Branhagen

Arboretum recommends cabin-friendly plants and shrubs.

Cabin owners know the drill. Head up (or over) to the lake in springtime for opening, plant the garden beds and flower boxes, return home and hope for the best. At subsequent visits, arrive to find death-by-thirst plants or a florae crime scene, thanks to the local rabbits and/or deer populations.

Alan Branhagen, director of operations for the Minnesota Landscape Arboretum, offers ways to increase the odds of having healthy cabin plants.


Annuals: Consider spiny succulents (agave, aloe, crown-of-thorn, echeveria and sedum), herbs (basil, borage, cilantro, dill, lavender, parsley, rosemary and sage) and typical annuals (marigold, petunia, salvia and verbena).

Perennials: Think herbs (thyme, hardy oregano, mint in containers and hyssop), wildflowers (anise-hyssop, coreopsis, baptisia/wild indigo, aromatic aster and showy goldenrod). How about ferns (maidenhair, Christmas and wood-fern). Traditional perennials (alliums/ornamental onions, bleeding heart, catmint, daffodils, meadow sage, iris and beloved peonies) are options, too.

Shrubs: Most evergreens are favorite browse in winter. Northern bush-honeysuckle, potentilla, snowberry and coralberry are among the few shrubs deer leave alone.

Drought tolerant and no deadheading

Try succulents and most herbs (listed above). Marigolds seem to re-bloom, regardless of deadheading. Petunias (select Wave series) don’t require deadheading, and geraniums are drought tolerant. Don’t forget colorful foliage plants (coleus, dusty miller, helichrysum and silver falls vine) and Swedish ivy.  The pendant blue succulent burro’s tail is making a comeback in popularity, too.   

Best time to plant

It is best to plant trees, shrubs and perennials in the fall, so they require less watering, as they are going into dormancy and focusing on root growth. In general, watering protocol for new elements varies based on the plant, soil and weather. The equivalent of an inch of rainfall is what is said for turf, but spring-planted trees and shrubs will need more, especially if they are in sandy soils. Clay soil is better at holding moisture.

Lake-friendly fertilizers/weed killers

Follow the directions on the label, and more is NOT better. Lake-friendly fertilizers are those with no or very little phosphorous—the middle number in their NPK. The (nitrogen-phosphorus-potassium) rating should be zero or very low. Most of our natural soils do not require added phosphorous, so it simply runs off and creates algal blooms in waterways.

Embrace your inner weeds! Target specific weeds, and don’t blanket spray. Follow directions, and read about the impact to pollinators and aquatic life.

Protect landscaping at closing

Fall-planted evergreens can benefit from burlap protection against the winter sun and wind. Deer and rabbit excluding fencing, even if temporary, can be critical in the winter. Hardware cloth wrapped around the base of fruit and ornamental crabapple trees can protect from winter voles, which may eat the bark from their runs under the snow. —
