TIPS:
Know Your Zone:
Do not rely soley on the USDA hardiness zone maps because they indicate the zone for an area as a whole not taking into consideration small areas that have diffrent climates. Review the extreme winter low temperatures and see where the climate in which you live fits into a hardiness zone. While you wouldn’t grow tomatoes in an area where summer nighttime temperatures dipped into the 40s’, you may grow other plants in this zone that would thrive with the cooler temperatures.
Patience, Patience, Patience
Growing season starts later and ends earlier than the season down the hill. It may be tempting to begin summer gardening, but a successful garden needs to be started at the correct time.
Microclimates
These areas of warmer, cooler, wetter or dryer climates in a landscape may be natural or you can create them yourself. Stonescaping is a common way to create a microclimate. The stones absorb heat, moderate the soil temp, keep soil moist under the stone and create little pockets of shade, especially for the roots. Use a large milk jug with the bottom cut out and place the jug over new plants to create a warm microclimate. Place the cap on the jug if a cold night is forcast.
Use Mulch
Gravel mulch will warm the soil therefore extends the growing season. A must! Use gravel mulch around cacti, succulents and perennials that don’t like organic mulch.
Select Deer Resistant Plants
Select plants that don’t appeal to deer. If you plant what is appealing to them, and plant it in abundance, they will eat what they like and leave certain plants alone. Deer repellent or a barrier of some kind are also solutions.
While different, high altitude gardening is rewarding offering a garden that is spectacular and different from gardens at lower elevations.
