Microclimate Matching in Your Landscaping Plan

/in , , /by /Water News Network

Earlier in our Conservation Corner series, we described how to map the different types of microclimates present in your landscaping. Using this information helps homeowners arrange plants in a new sustainable landscape. For the most efficient water use, plants should be grouped together with similar water needs according to their preferred microclimate.

In nature, plants that like lots of water are found along the banks of a stream, or grouped together at the base of a depression. Plants that need fast-draining soils so roots don’t rot might be found on hillsides. Plants that love lots of sunshine won’t grow in the shade of a tree.

Microclimate Matching in Your Landscaping Plan

Earlier in our Conservation Corner series, we described how to map the different types of microclimates present in your landscaping. Using this information helps homeowners arrange plants in a new sustainable landscape. For the most efficient water use, plants should be grouped together with similar water needs according to their preferred microclimate.

Follow The Microclimate Map

Look to the Microclimate Map for smart guidelines on choosing landscape plants. Consider this example yard with three identified microclimates:

  • A front yard in full sun most of the day.
  • A moist depressed area in full sun. This area will retain moisture more than the rest of the yard, so you could use this area for rain catchment. Raise hillside areas surrounding the depression and allow them to drain freely.
  • A shady area under the canopy of a neighbor’s large tree.

When selecting landscaping plants, the yard in this example will require at least three different groupings of plants.

  • Sun-loving plants that prefer their roots dry and in fast-draining soil
  • Sun-loving plants tolerant of wet feet in winter months, which thrive in heavier clay soils
  • Plants tolerant in dry shaded areas

A final consideration before heading to the local nursery or garden center: how will you irrigate your plants?  Check the Plant Factors for each of the plants to make sure their water needs are all similar in each area. A previous Conservation Corner feature has information about Plant Factors.

Plants Speak Latin

Many plants have similar common names in English. Shopping for plants by their common names can lead to confusion between two very different plants. Instead, the best way to shop for plants is to use the Latin name. This reduces any miscommunication and any surprises in your landscaping.

How to Choose Plants for Landscape Microclimates

/in , /by

Every garden has completely different cultivation characteristics, even those located in the same general climate zone. For example, there will be areas where plants will flourish.

Numerous features affect your growing conditions. Structures, walls, fences, and other plants can affect the amount of sun and shade in a garden. There can be hills and hollows in your front yard that may collect cold air. Or, because your property is sloped, you don’t get frost when your neighbors do.

Individual microclimates may differ significantly from the general climate of an area. To be sure you match the right plant choices to your conditions, you need to identify and map these microclimates. Start by walking around your property at different times of day. Observe conditions and take notes.

Choose plants that will thrive

Determine which plants will work in your new garden, and which should be removed or avoided. Outline the canopy area of the plants being retained. Note the name, general size, and health of the plants.

Do any of these plants seem “unthirsty?” Many plants can thrive on less water when they are well established, with deep healthy roots. Old rose bushes and large shade trees are two good examples. These drought-tolerant plants are worth keeping if possible, especially if they are mature.

Note sun and shade patterns

Mark the areas that receive sun all day, and areas that are shaded all or part of the day. Also note which areas receive only partial sun, or a few hours of direct morning sun, midday sun, or late afternoon sun.

In choosing landscaping plants, make sure to select those that are appropriate to the sunlight patterns of the garden. Plants marked as “full sun” will not be happy in full shade, and vice versa. Don’t work against their requirements.

Group plants for similar needs

Group plants with similar water requirements together. Make sure plants with different water needs are not combined. Some sun-loving plants have moderate water needs, and some have very low water needs. If these are mixed together, one will always suffer if the watering routine works for the other types.

Program Preps Communities for Next Drought

/in , /by /The Sun-Gazette (Exeter, Calif.)

Whether or not you accept climate change as a reality, one thing is for certain – the San Joaquin Valley will have another drought. Throughout recorded history, the semi-arid Valley has had extended dry spells with little precipitation to moisten its fertile soil creating a micro climate of economic crisis. The Valley is still dealing with the effects of an overdrated groundwater basin including abandoned private wells, contamination in remaining rural wells and subsidence in its water conveyance systems.

Match Your Landscape Plants To Your Microclimates

A previous Conservation Corner article explained how to map the different types of microclimates present in your landscaping. This information can help homeowners effectively arrange plants in their sustainable landscapes. For the most efficient water use, plants should be grouped together with similar water needs in their favorite microclimate.  

In nature, plants that like lots of water are found along the banks of streams, or grouped together at the base of landscape depressions. Plants that need fast-draining soils so roots don’t rot might be found on hillsides. Plants that love lots of sunshine won’t grow in the shade of a tree.  

Follow the microclimate map  

Look to the Microclimate Map for guidelines on choosing landscape plants. Here is a hypothetical yard with three microclimates:  

  • A front yard in full sun most of the day. 
  • A moist, low-lying area in full sun. (This area will retain moisture more than the rest of the yard, so you may want to use it for rain catchment. Hillside areas surrounding the depression are raised slightly, and drain freely.) 
  • A slightly shady area under the canopy of a neighbor’s large tree, and another one near the front entry to the house. 

Three distinct plant communities 

Selecting plants for the yard in this example will require at least three different groupings:  

  • Sun-loving plants that like their roots dry and thrive in faster-draining soil
  • Sun-loving plants that can tolerate “wet feet” in winter months, and thrive in heavier clay soils
  • Plants that can tolerate dry, shaded areas 

There is another consideration before heading to the local nursery or garden center: How will these plants be irrigated? Check the Plant Factors for each of the plants to make sure their water needs are all similar in each area. Read this previous Conservation Corner story for information about Plant Factors.

Map Your Microclimates

Every garden has areas where plants flourish, and other areas where plants struggle. Structures, walls, fences and other plants can affect the amount of sun and shade in a garden. Every garden is completely different, even if it is located in the same general climate zone. 

There may be hills and hollows in your front yard that collect cold air. Or, if your property is sloped, you may not get frost when your neighbors do.  

The first step to a new or renovated landscape is walking around your property during the day and observing it closely.  

Which plants are keepers? 

Decide which plants work and which should be removed. Outline the canopy area of the plants being retained. Note the name, general size, and health of the plants. Which are more drought-tolerant? Many plants can thrive on less water when they are well established, with deep healthy roots. Old rose bushes and large shade trees are two good examples.

In choosing landscape plants, select those that are appropriate for the sunlight patterns of the garden. Plants marked as “full sun” will not be happy in full shade, and vice versa.  

Group plants for similar needs 

When selecting and grouping plants, note the water requirements of each plant. Make sure plants with different water needs are not placed together. Some sun-loving plants have moderate water needs, and some have very low water needs. If these are mixed together, one will always suffer if the watering routine works for the other types.
