Manure: A Gardener’s Guide to Soil Improvement

Introduction

Manure is a natural fertilizer that can greatly improve the health and fertility of your garden soil. It is made from the droppings and bedding of animals, such as horses, cows, pigs, and chickens. Manure is rich in organic matter, nutrients, and beneficial microorganisms that help plants grow strong and healthy.

Types of Manure

There are many different types of manure, each with its own unique benefits and drawbacks.

Horse manure: Horse manure is a good all-purpose manure that is easy to use and has a sweet fragrance. It is widely available from local stables.
Cow manure: Cow manure is another good all-purpose manure that is often sold as “farmyard manure” from garden centers.
Pig manure: Pig manure is a “sticky” manure that is good for improving sandy soils.
Chicken manure: Chicken manure is very strong and should be composted before using it on plants. It is high in nitrogen, which helps speed up composting.
Pet manure: Manure from herbivorous pets, such as rabbits and guinea pigs, can be composted and used on the garden.

Green Manure

Green manure is a type of cover crop that is grown specifically to be dug into the soil to improve its structure and fertility. Green manure plants are often used as a sustainable alternative to animal manure.

Benefits of Manure

Manure offers many benefits for garden soil, including:

Mulching Lavender: A Guide for Beginners

Introduction

Lavender is a popular herb known for its beautiful purple flowers and fragrant leaves. It’s often used in gardens, landscapes, and for its culinary and medicinal properties. However, mulching lavender can be tricky because it prefers well-drained soil and arid conditions. This article will provide a comprehensive guide to mulching lavender, including the best types of mulch to use and how to avoid common mistakes.

Choosing the Right Mulch for Lavender

The key to successful lavender mulching is choosing a material that will help keep the soil well-drained and prevent moisture from accumulating around the roots. Here are some of the best options:

Crushed rock or pea gravel: These materials are ideal because they allow water to drain quickly and don’t retain moisture.
Nut shells: Walnut shells or almond shells are a good choice because they break down slowly, adding nutrients to the soil over time.
Pine needles: Pine needles are naturally acidic, which helps create the ideal soil conditions for lavender.
Oyster shells: Crushed oyster shells not only provide good drainage but also add calcium to the soil.
Coarse sand: Coarse sand is a budget-friendly option that helps improve drainage and prevents soil compaction.

Mulches to Avoid for Lavender

Certain types of mulch can be harmful to lavender, especially those that retain moisture or decompose quickly. Avoid using the following:

Wood or bark mulch: These materials can decompose and create a moist environment that encourages root rot.
Compost: Compost is too rich and can burn lavender roots.
Straw (almost always): Straw can trap moisture and lead to root rot, especially in moist climates.
Fine sand: Fine sand can compact the soil and prevent water from draining properly.

Using Straw or Evergreen Boughs for Mulching Lavender

In arid climates north of USDA hardiness zone 9, you can use a thin layer of straw to provide extra insulation during the winter months. However, it’s crucial to apply straw only after the ground freezes and the plants are completely dormant. Remove the straw in the spring as soon as the danger of extreme cold has passed.

You can also use evergreen boughs to provide winter protection. Lay the boughs over the lavender plants, but be sure to remove them in the spring to prevent moisture buildup.

Additional Mulching Tips

Apply a thin layer of mulch: About 1 inch (2.5 cm) of mulch is sufficient.
Keep mulch away from the crown: Don’t pile mulch against the base of the plants, as this can lead to rot.
Water deeply before mulching: Water the lavender plants thoroughly before applying mulch to help prevent the soil from drying out.
Monitor soil moisture: Check the soil moisture regularly and water only when necessary.

Conclusion

Mulching lavender is an essential aspect of caring for these beautiful plants. By following these tips and choosing the right mulch materials, you can help your lavender thrive and enjoy its beauty for years to come.

Lilac Pruning: A Comprehensive Guide for Beginners

Introduction

Lilacs are beautiful shrubs that add color and fragrance to any garden. However, to keep them healthy and looking their best, regular pruning is essential. This guide will provide you with all the information you need to know about pruning lilacs, including when to prune, how to prune, and special techniques for rejuvenating overgrown shrubs.

When to Prune Lilacs

The best time to prune lilacs is after they have finished blooming in late spring. Avoid pruning in summer or fall, as this can damage new growth and reduce flowering the following year. If you need to do a light pruning, do so in early spring before new growth begins.

How to Prune Lilacs

Regular Maintenance Pruning:

Remove one or two of the oldest stems near the ground each year.
Keep the shrub in a fountain shape, with equal weight on both sides.
Thin the lilac bush by cutting out dead or damaged stems and branches that cross or rub against each other.

Rejuvenation Pruning:

For overgrown lilacs, use a three-year pruning cycle.
In the first year, cut out one-third of the largest, thickest stems close to the ground.
In the second year, remove another one-third of the stems.
In the third year, trim back the final third of thick branches.
This will gradually reduce the height of the shrub and stimulate new growth.

Renovation Pruning:

For severely overgrown lilacs, use renovation pruning.
Cut the entire bush back to 6-8 inches above the ground in late winter.
Many new shoots will develop after this pruning.
In the following winter, select a handful of the strongest shoots to provide a new framework for the shrub.

Special Pruning Techniques

Cutting Back Overgrown Stems: When pruning overgrown stems, it’s generally better to cut the entire stem rather than just the tops.
Trimming for Air Circulation and Light Penetration: If your lilac bush is dense, you may need to trim some of the inner branches to allow more air and light to reach the center of the plant.
Removing Spent Blooms: To prevent seeding and encourage more blooms, remove spent blooms all the way back to the stems.

Tips for Pruning Lilacs

Use clean, sharp pruning shears.
Make clean cuts at a 45-degree angle.
Avoid cutting into the main trunk of the shrub.
If you’re unsure about how to prune your lilac, consult with a professional arborist.

Benefits of Pruning Lilacs

Regular pruning of lilacs provides numerous benefits, including:

Maintains a healthy and vigorous shrub
Improves flowering and fragrance
Controls the size and shape of the plant
Removes dead or diseased branches
Encourages new growth and rejuvenation

By following these simple tips, you can keep your lilacs healthy, beautiful, and blooming for many years to come.

written by Gregory 3 minutes read

Transplanting Weigela: A Step-by-Step Guide for Beginners

Introduction

Weigela bushes are beautiful and fast-growing shrubs that can add a touch of color and interest to your garden. However, if you planted them in a space that’s too small or started them in containers, you may need to transplant them to a more suitable location.

Can I Transplant Weigela?

Yes, you can transplant weigela bushes. In fact, it’s recommended to transplant them if they have outgrown their current location. Weigela bushes can grow up to 8 feet tall and wide, so it’s important to give them enough space to grow and thrive.

When to Transplant Weigela Bushes

The best time to transplant weigela bushes is during their dormant period, which is late fall or early spring. Avoid transplanting during the growing season (summer), as this will stress the plant unnecessarily. The middle of winter may also be a problematic time for transplanting, as the soil may be tough to dig in.

Steps for Transplanting Weigela

Before You Start:

Choose a new location for your weigela bush that has enough space for it to grow and receives full sun.
Dig a hole that is twice as wide as the root ball of the weigela bush and just as deep.
Amend the soil in the hole with compost to improve drainage and fertility.

Transplanting the Weigela Bush:

Prepare the Weigela Bush: Dig around the base of the weigela bush, creating a circle that is slightly wider than the root ball. Cut the roots that are growing outside of the circle to encourage the growth of new, compact feeder roots.
Dig Up the Weigela Bush: Carefully dig up the weigela bush, taking care not to damage the root ball.
Place the Weigela Bush in the New Hole: Place the weigela bush in the new hole and backfill with soil, tamping down gently to remove any air pockets. Ensure that the bush is planted at the same depth it was previously.
Water the Weigela Bush: Water the weigela bush deeply and continue to water it regularly until it has become established in its new location.

Weigela Plant Care After Transplanting

Water the weigela bush regularly, especially during the first growing season after transplanting.
Fertilize the weigela bush in the spring and fall with a balanced fertilizer.
Prune the weigela bush as needed to remove any dead or diseased branches and to shape the plant.

Tips for Success

When digging up the weigela bush, try to preserve as many of the feeder roots as possible.
If the root ball is too large or heavy to move, you can divide the weigela bush into smaller sections.
Water the weigela bush deeply after transplanting to help settle the soil and remove any air pockets.
Mulch around the weigela bush to help retain moisture and suppress weeds.

By following these steps, you can successfully transplant your weigela bush and enjoy its beauty and fragrance for years to come.

written by Donna 3 minutes read

When to Transplant Trees, Shrubs, and Perennials: A Guide for Gardeners

Introduction

Moving plants from one location to another, known as transplanting, is a crucial gardening task. However, timing is everything when it comes to transplanting. In this article, we’ll explore the best times to transplant trees, shrubs, and perennials, as well as provide tips on how to make the process successful.

Best Time to Transplant Trees and Shrubs

Fall and spring are generally considered the best seasons for transplanting trees and shrubs.

Fall: Fall is an ideal time for transplanting because the weather is cooler and moister, allowing the plant’s roots to establish themselves before the heat of summer. Roots that are well-anchored help the plant absorb nutrients and water, promoting healthy growth.
Spring: Spring is also a good time to transplant, as the new growth hasn’t started yet. However, it’s important to water the plants regularly during the early stages of growth to prevent them from drying out.

When to Move Perennials

Perennials are plants that live for more than two years. The best time to move perennials is either in spring or fall, when they are not in bloom.

Spring: Transplant fall-blooming perennials in spring, as they will have time to establish their roots before winter. Avoid moving perennials in hot weather, as the heat can stress the plants.
Fall: Transplant spring-blooming perennials in fall, as they will have time to adjust to their new location before the cold weather sets in.

Factors to Consider When Transplanting Big Plants

When transplanting large trees or shrubs, there are a few additional factors to consider:

Root pruning: Root pruning is a technique that can help reduce transplant shock and promote root growth. It involves cutting some of the roots around the plant to encourage the growth of new, feeder roots.
Timing: If you root prune in fall, transplant the plant in spring. If you root prune in spring, transplant the plant in fall.

Tips for Successful Transplanting

Choose a healthy plant: Select plants that are free of pests and diseases.
Prepare the planting hole: Dig a hole that is twice as wide as the root ball and just as deep.
Amend the soil: Mix compost or other organic matter into the soil to improve drainage and fertility.
Handle the roots carefully: Gently loosen the roots and remove any damaged or circling roots.
Set the plant in the hole: Place the plant in the hole and backfill with soil, tamping down gently to remove any air pockets.
Water deeply: Water the plant thoroughly after transplanting to settle the soil and provide moisture.
Mulch around the plant: Spread a layer of mulch around the base of the plant to retain moisture and suppress weeds.

Conclusion

Transplanting trees, shrubs, and perennials at the right time can greatly increase their chances of success. By following the tips outlined in this article, you can ensure that your transplanted plants thrive in their new location.

How to Keep Your Soil Warm in Winter: A Comprehensive Guide to Soil Heating Cables

by Gregory December 14, 2020

written by Gregory 4 minutes read

How to Keep Your Soil Warm in Winter: A Guide to Soil Heating Cables

Introduction

Do you want to extend your gardening season and grow plants even in the cold winter months? Soil heating cables are a great way to do just that. By providing consistent warmth to the soil, you can protect your plants from the cold and help them thrive.

Why Warm the Soil in Winter?

There are many benefits to warming the soil in winter, including:

Extending the growing season: You can start planting earlier in the spring and harvest later in the fall, or even grow plants year-round.
Overwintering plants: You can protect plants that are not fully hardy from the cold and keep them alive until spring.
Starting transplants or root cuttings: You can get a head start on your gardening by starting seeds or taking cuttings indoors and then transplanting them into the warm soil in the spring.
Hardening off transplants begun indoors: You can help your indoor-grown plants adjust to the outdoor environment by gradually exposing them to the cold in a warm soil bed before transplanting them into the ground.

Structures to Use with Soil Warming Cables

Simply adding cables to an open garden bed is not very effective, as the soil will lose heat to the air. Instead, it’s best to use cables within a structure that retains heat, such as:

Cold frame: A small, enclosed structure that is typically used to start seeds or overwinter plants.
Hot box: A larger, insulated structure that can be used to grow plants throughout the winter.
Plastic tunnel: A greenhouse-like structure that can cover a larger area and provide protection from the elements.

Choosing Your Cables

When choosing heating cables, consider the length and wattage you need. The length of cable you need will depend on the size of the area you want to heat, and the wattage will depend on the climate and how much heat you need.

For milder climates, aim for about 10 watts per square foot.
For colder climates, go up to 12 watts per square foot.

Spacing the Cables

To determine the spacing between the loops of cable, multiply the watts per foot of the cable you purchase by 12 and then divide that number by the wattage per square foot you want for your bed. This will give you the spacing in inches between loops of cable.

How to Install Soil Heating Cables

To install soil heating cables in a cold frame or similar structure:

Choose a location where you can easily plug in the cables.
Dig down and remove soil to a depth of 6 to 12 inches.
Fill the space with about 4 inches of sand.
Lay the cable on top of the sand, spacing the loops according to your calculations.
Cover the cable with more sand and hardware cloth.
You can then put containers right on top or add potting soil over the cloth and plant directly in the soil.
Attach a thermostat to the cable to track the temperature and adjust the settings as needed.

Safety Precautions

Using heating cables is generally safe, but it’s important to take some precautions:

Never cut or splice a cable.
Ensure that the cables will not touch and overheat.
If you are unsure if you can do the installation safely, hire an electrician.

Conclusion

Soil heating cables are a great way to extend your growing season and protect your plants from the cold. By following these tips, you can safely and effectively install and use soil heating cables to keep your soil warm in winter.
