Consider Garden Soil pH in your Landscape Design

Do you know your garden soil pH level? If not, you should get a soil test before planning your landscape design. Some plants just do not thrive in your garden despite your best efforts.

As gardeners, we don’t need to know the scientific details of soil pH. Just understand that pH is measured on a scale of 1-14, with acidic soil (pH below 7.0) or alkaline soil (pH above 7.0), and neutral soil at 7.0.

We should have this information on hand as plants can absorb certain nutrients only when the pH is suitable. Adding more fertilizers is futile if the problem lies in the soil pH.

Most garden plants prefer a neutral pH between 6.2 to 7.0. Some plants are more sensitive to pH; for example, lilacs and clematis thrive in alkaline soils while rhododendrons and blueberries prefer lower pH.

Generally speaking, if your plants are growing healthily, your garden soil pH is ok. But if the plants cannot thrive, it is worth doing a soil test.

There are many types of soil pH testers available. The Luster Leaf 1818 Rapitest Mini 4-in-1 Soil Testergarden soil pH tester has been working well for me. Or bring a sample into your local Cooperative Extension office, to be tested for a nominal fee. Once you know your soil pH, you can adjust it slowly.

One method is to add lime to raise pH or sulfur to lower it in different parts of your landscape. The amount to add depends on your soil test result.

However, don’t think of lime or sulfur as a quick fix. It can take months to register a change in the soil pH and you will need to periodically test your soil to ensure the pH maintains at optimal level.

Sometimes, it is easier to plan your landscape design in such a way that the plants suit your soil pH.

Measuring Garden Sunlight Optimizes Landscape Design

How do we determine the amount of sunlight a garden receives? Measuring garden sunlight can be tricky even for experienced gardeners or landscape designers, especially if there are trees and shady spots.

You can start by sketching out the garden, including aspects like dry, wet, sloping and play areas. For example, if there’s a pond, take note of pets or human traffic, you don’t want your prized flowers to be trampled upon. Also draw in rocks, fences, sheds, existing trees, shrubs, and hedges which can cast shadows.

Next, map out the sunlight areas to determine optimal planting positions. Some plants bloom at different times of the day. For example, morning glories bloom in the morning, four o’clocks in the afternoon shade, and jasmine gives a sweet-scented blossom in the cool evening.

To do this, you have to spend a day outside to observe the sun. Every half-hour, note down the sun’s position. For example, the corner of the garden may get the most sunlight at 6:30; write “6:30″ in that spot, and draw a line to mark where the shade begins. Next, at 7:00, draw another line, and so on.

Ultimately you compile the raw data in another map, showing total number of hours each area was basked in golden sunlight, Say the corner may be lit at 6:30 and shaded by 10:30, meaning four hours of flower-producing light.

Bear in mind that amount of sunlight in the garden will change throughout the year. A tree may throw up a larger shade in the fall due to the change in angle of the sun during the season. You can take advantage of this by planting early spring bulbs in a garden area that is sunny in early spring but shady in the summer.

Before you spend any money on seeds or waste your effort in planting, measure the garden sunlight properly first. If a section of your garden doesn’t get enough sun, don’t ignore it, just put in plants that thrive in shady areas.

Besides sunlight, a good landscape design will also consider time of year a flower blooms, color, and height of plants. The time of day certain flowers bloom will make your garden interesting when you plant morning glories, four-o’clocks and jasmine. Your little Eden will bloom from dawn till dusk.

6 Tips for Beautiful Landscape Design

Landscape design is not as difficult as it seems. You just need to grasp the basic ideas and your landscape design can be as eye-catching as the pros.

Here are some tips to help you makeover your landscape for a more pleasant stay in your house.

1. Consistency and Repetition

Trust me, you don’t want a haphazard landscape. Too many unrelated objects can make the garden look cluttered and unplanned.

Try to use repetition of plants or boulders throughout the landscape, though too much of one element can make the garden look boring or monotonous. It is up to the individual how many different elements they want to repeat.

Being consistent in height, size, color of the different elements is also important in creating a harmonious whole. You can use specific themes for easier design, like rock, butterflies, waterfall, ornaments, etc.

2. Simplicity

When it comes to design, especially for beginners, it is best to KISS (Keep It Simple, Stupid!).

Just pick two or three colors and repeat them throughout the garden. Keeping decor and hardscape to a minimum.

3. Balance in design

There are basically two types of balance in landscape design. Symmetrical and Asymmetrical.

Symmetrical balance is like a mirror image where there are more or less equally spaced matching elements in the landscape design. With a garden equally divided, both sides could share the same shape, form, height, color, theme, etc.

Asymmetrical balance is slightly more complex. While textures, forms, colors, etc. may remain constant, shapes and hardscapes may be random. End result is both sides having different themes and contrasting attractions.

Contrast and harmony can also be achieved using plants. For example, fine vs coarse foliage, round leaves verses spiked leaves, etc. Plant height, color, and texture may be varied in different areas but each area should be consistent in its theme.

4. Color

Color makes the landscape come alive. Bright colors are full of energy and catch your attention while cool colors are more detached and make an object seem farther.

Grays, blacks, and whites are neutral colors and are best used in the background with bright colors in the foreground. However, to increase depth in a landscape, you can use dark and coarse textured plants in the foreground and use fine textured and light colored plants in the background.

5. Natural transition

Transition can be achieved by the gradual, ascending or descending, arrangement of different elements with varying heights, forms, or colors.

For example, a good transition would be a stair step effect from large trees to medium shrubs to bedding plants. This creates a sense of depth and distance, making the garden seem larger. Conversely, transitioning from shorter to taller plants make the plants seem closer to you.

A transition from straight lines which are forceful to curvy lines which are gentle and flowing is also easier on the eye.

6. Proportion

This refers to the size of elements (length, breadth and depth) in relation to each other. It is easy to achieve proportion using some common sense.

For instance, having a huge statue in a small garden will be out of place. Or placing a small waterfall and pond in the center of a large open yard make it insignificant.

Since proportion is relative, you can scale to fit the elements by creating different enclaves in the garden. A small water feature can be proportionate if placed in a corner or edge of a large area. It then becomes a focal point with its own distinct aura. An sitting area or theme can be created around it.

The choice of plants is also important so that they are not out of proportion.
