Spring Cleaning in the Garden

Spring has sprung. In California this season normally signals warmer temperatures, strong breezes and the dwindling of our rainy season. For Central Coasters though, the weather still carries remnants of winter chill and dampness.

So what’s a gardener to do, you ask? We suggest you slog through messy garden beds and soggy lawns to assess your landscape’s condition. If you’re like most of us, general garden clean up is in order. Yeah, yeah, we know…the maintenance end of gardening holds little magic for most of us, yet it is crucial to the success of spring and summer planting.

Some garden jobs best done in March and April:

- Lawn top-dressing

- Plant bare-root (packaged) perennials

- Tend flowering shrubs – clean up spent blossoms, feed with acid fertilizer

- Sow annuals – cosmos, nasturtiums, sunflowers and zinnias

- Sow: carrots, spinach and chard

- In April – set out transplants of tomato, peppers and squash

- Sow: beans, corn and squash

- Water

Interestingly enough, the rainy weather helps indentify low spots that might hamper drainage. Make note of these areas, using soil amended with compost to fill them in. Since it’s too early to do much planting, you’ll want to focus on prepping soil for future plantings; both flower and vegetable. In addition, you may amend surrounding soil as well as soil in planting beds you’ve designated for spring and summer vegetables.

Victory Garden author James Crockett calls compost “the caviar of organic materials” for its ability to retain moisture and provide the necessary 5% Soil Organic Matter to soil. Harvest Blend Compost is a premium compost; wonderful for use as lawn top-dressing, soil amendment, tree and shrub backfill mix and in flower and vegetable gardens.

To amend soil with compost: you will first need to loosen the soil. If the soil is too wet from too much rain, let the soil dry for a few days as wet, heavy soils are difficult to work. For dry soil or new garden plots that have not been worked before, a thorough watering a few days ahead of time will make your job easier. Using a rototiller for large areas or a fork and spade for existing beds, break up the soil to a depth of approximately six to twelve inches (the lower range is appropriate for existing beds).

Spread compost evenly over soil. Blend compost into the soil using a gardening fork or your rototiller (if you don‘t own a rototiller, they’re often available through equipment rental locations). After you have thoroughly worked the materials into the garden soil, level the area with a rake.

Your soil is now properly replenished for the upcoming planting season. Over the next few months, the organic amendments you have added will continue to break down, building healthy soil for a plentiful gardening season ahead; providing a slow-release of nutrients that will benefit growing plants. Remember, these nutrients won’t last forever and should be replenished periodically throughout the year.

Many organics naturally occurring in your yard are ideal for building up your garden soil. A simple lawn mowing provides one of the best resources for organic garden soil improvement. Mow your lawn and bag or rake the shredded leaves and grass clippings to work into your soil. Not only will the grass and leaf bits break down to provide essential soil nutrients, but they will work to loosen and aerate the soil as well, increasing root health during the next spring and summer growing season. This will aid in soil drainage, too.

Before you know it, we’ll be experiencing warm evenings and even warmer days; perfect for planting all the tasty vegetables we’ll be enjoying throughout summer and fall. Naturally!

Soil. It's What You Find Under Your Feet!

What’s the difference between soil and dirt? Dirt is what you find under your fingernails. Soil is what you find under your feet. Think of soil as a thin living skin that covers the land. It goes down into the ground just a short way. Even the most fertile topsoil is only a foot or so deep. Soil is more than rock particles. It includes all the living things and the materials they make or change.

Soil Organic Matter (SOM) is that fraction of the soil composed of anything that once lived. Most soil lacks enough organic matter to support healthy plant growth. The Strive for 5% campaign was developed to help us increase SOM for healthy soil!

Truly healthy soil has between 3% and 5% organic material. That level can be maintained ONLY IF you add organic matter to the soil at the surface year in and year out. The plants, the earthworms, and the microbes need that additional matter to sustain a healthy soil. In the woods and prairies, that added organic matter came from dead leaves or dead grasses decomposing each year. We need to replicate that process in our lawns to be able to maintain a healthy organic content in our soil.

But few residential landscapes have soil this rich with organic material. The reality is that the soil under American lawns typically contains less than 1% organic material. This is because over a ten or twenty year period not only was no new organic material introduced, but the most abundant natural sources such as leaves and grass clippings were regularly collected and disposed of in our weekly trash pick-up.

A healthy soil needs a steady source of new organic material. It is constantly decomposing and yielding nutrients for the grass plants and must be replaced. The black fibrous material (called "humus") that results from the decomposition of grass clippings and other organic material eventually has little food value left. But, it does have enormous value in aerating the soil, in storing water, and in feeding key microorganisms needed for other tasks.

While leaving grass clippings on the lawn provides some organic material, it is not enough to consistently provide 3 or 5 %. You must provide more. And how may I provide more organic matter, you might ask? The answer is simple; STA Certified Compost! Applying a layer of compost to lawns twice a year (called 'top dressing') adds vital nutrients, increasing soil's water holding capacity and soil structure. Top Dressing is widely recognized by landscape pros as the most environmentally responsible method of lawn care. Compost is also beneficial for erosion control, turf establishment, tree & shrub backfill mix and used in flower & vegetable gardens for vibrant blooms and healthy veggies.

STA Certified Harvest Blend Compost can do many things for your soil. Benefits include:

·        Improving soil structure, porosity and density to ensure a healthier root environment

·        Infiltrating heavy soils, thereby reducing erosion

·        Increasing water holding capacity of soil so that water is used more efficiently

·        Stabilizing pH and improving the soil’s ability to hold nutrients

·        Supplying valuable microbes, micro and macronutrients and organic matter to the soil environment

·        Helps to suppress soil-borne plant pathogens

·        Binds and degrades specific pollutants

We encourage you to schedule a visit to one of the participating STA composting facilities to get a first hand look at the commercial composting process.

A New Year! Resolve to Keep it Clean

We've had an unusual amount of rain recently, which is both good news and bad news. Restoring depleted  water supplies is always a good thing, but how about the bad? Have you thought about the unexpected negative effects this rainfall may provide our lakes and streams? How on earth can organic yard waste contaminate bodies of water? On the Central Coast, rain flows across lawns or hard surfaces such as rooftops, paved areas, and bare soil. As it flows, this runoff water carries sediments, leaves, grass clippings, litter, and other landscape waste into streets and gutters leading to storm sewers. Unlike household wastewater, stormwater runoff receives almost no treatment. As a result any particles that enter the storm drain will probably end up in a stream or lake.

 

We have a problem when excess nutrients allow the growth of algae and rooted plants in lakes and streams. Too much algae in the water can use up valuable oxygen, kill fish, create bad odors, toxin production, and ugly surface scum.  Too many rooted aquatic plants can clog boat props, hamper fishing, pollute beaches and limit fish growth. Although plant material and nutrients slowly build up in lakes and streams, a neighborhood or community with poorly managed yard waste practices can be a major contributor to the problem and cause unnecessary degradation of lakes and streams.

What is Landscape Waste?

Sources of landscape waste include grass clippings, leaves, tree and shrub trimmings, organic mulch, and plant materials from vegetable and flower gardens. By weight, grass is the largest component averaging half of all yard waste. Leaves and brush each provide nearly one quarter. Other landscape wastes add less than 10 percent. On average, nearly 200 pounds of yard waste is produced per person each year.

Managing Landscape Waste. Controlling organic waste and reducing potential contamination of surface water can be accomplished in several ways. One way to control landscape waste is through source reduction. Amending soil with compost, grasscycling and lawn top dressing will reduce large amounts of landscape waste.

Grasscycling is the natural recycling of grass clippings by leaving them on the lawn when mowing. Leaving grass clippings saves time, money, and protects the environment. Mowing takes less time since bagging and disposal aren’t involved. The clippings add beneficial organic matter and nutrients to soil. This in turn reduces fertilizer and water needs, which can minimize nutrient runoff entering storm drains. Be sure to cut grass when the surface is dry, keep mower blades sharp and never blow, sweep or hose clippings onto the street.

Compost benefits
Amending heavy clay soils with compost improves water infiltration and drainage by improving soil structure. Compost also absorbs water and improves the water and nutrient holding capacity of sandy soils. To conserve moisture it is essential to have soil with good water retention. In addition to improving soil structure, decomposing compost will slowly release plant nutrients. Check out Google Maps for a Harvest Blend dealer near you.

Lawn Top dressing
Topdressing the lawn is the process of adding a layer of compost to the lawn surface. Top dressing benefits the lawn as it increases soil quality, adding nutrients and oxygen to plant roots. Sandy soils will be able to retain moisture better, and so the lawn will be more resistant to drought. Clay soils will drain better, thus improving root development. Another benefit of top dressing the lawn is that it will help to even out any lumps and bumps on an uneven lawn, making the surface safe for play. Top dressing also stimulates the grass to produce new shoots, resulting in denser grass cover, which helps combat the onset of weed growth.

Top dressing with aeration: aerating a lawn before top dressing will allow nutrients in the compost to reach the soil. This is the best treatment for hard, compacted soils. Professional aerators may be rented from equipment supply centers.

Using Landscape Waste as Mulch
Using an organic mulch can help gardens in many ways. Mulch reduces weeds by cutting off their oxygen, so they’re unable to grow. Mulch also maintains consistent moisture conditions in gardens. Water loss through evaporation is decreased and soil erosion is decreased by reducing the effect of heavy rainfall. Soil temperatures are modified by mulch. And last but not least organic mulch adds nutrients and humus to the soil as they decompose.

Tree and shrub trimmings are another source of yard waste. These materials are a greater challenge since they are woody and don’t break down easily. They need to be shredded or chipped for quicker decomposition and to reduce waste volume. Chippers and shredders may be available to rent at local landscape supply centers, so give ‘em a call. A 2- to 3-inch layer of shredded bark provides good weed control. Wood chips are slower to decay than shredded bark and can be used for pathway material in gardens. 

Limiting Landscape Waste

The best way to deal with landscape waste is to limit its production in the first place, or at least produce as little as possible. Choose trees and shrubs with their full growth in mind. Plants that need little or no pruning don’t produce much landscape waste. Sound yard waste management will benefit the landscape as well as surface and groundwater resources. No matter where you live, the size of your home, or the amount of time and money invested in the yard, everyone can do something to improve or maintain water quality.

Here are a few ways we can help insure clean water and a healthy environment through positive yard waste management.

• Add Harvest Blend Compost once or twice a year to build healthy soil and increase nutrients in the soil.
• Mow often enough to leave grass clippings on the lawn.
• Sweep grass clippings off of paved areas. Place them on the lawn or in a compost pile.
• Keep fallen leaves out of the street gutter or ditch, using them around the yard as practical or composting them.
• Do not dump yard waste down a storm drain or near surface water.
• Plan your landscape with the environment in mind, reducing intensely maintained areas.
• Recycle organic waste through sound composting practices and mulching.
• Mulch annual and perennial gardens with yard waste compost.
• Use organic mulch to suppress weeds, conserve soil moisture, and reduce soil erosion.
