What’s in a Number?

Fertilizer NumbersConfused about fertilizer numbers? What value do they have in organic gardening? A plant needs nutrients to survive. Most of these are provided by the soil, but soil varies tremendously in nutrient amounts, soil type, pH, and nutrient availability.

The three main nutrients that have been identified as absolutely necessary for plants are nitrogen (N), phosphorus (P) and potassium (K). These three are also known as macronutrients, and are the source of the three numbers commonly found on organic fertilizer labels. The numbers found on our All-Purpose Fertilizer, for example, are 5-5-5. This is the percentage by weight of the N, P, and K found in the fertilizer. (more…)

A Gardener’s Guide to Fertilizers

Organic FertilizersIn a perfect world, your garden’s soil would provide all the nutrients plants need. But in the real world, garden and lawn soil — and thus the plants that live in them — often needs a little boost. Improving the soil is the number one thing you can do to improve your garden, yard or landscape and organic fertilizers can help.

All plants need:

  • Macronutrients – nitrogen, phosphorus and potassium
  • Secondary nutrients – sulfur, calcium and magnesium
  • Micronutrients – iron, manganese, zinc, chlorine, boron, copper and nickel (in very small quantities)

Organic fertilizing can be as easy or as technical as you want it to be. For gardeners who don’t wish to spend a lot of time figuring out what individual plants want, there are commercial blends that can be used on all plants. (more…)

What’s the Big Stink About Organic Fertilizers?

FertilizersHere’s a list of some organic fertilizers you can encounter:

Manure for the garden comes from cow, sheep, poultry and horses. Pretty self-explanatory. Manure is known as a “complete” fertilizer; it has a lot of organic matter, but is low in nutrients. Manures are most valuable as organic soil amendments and mulches. Note: Beware of using fresh manure as a fertilizer because it can burn plants.

Blood meal is dried, powdered blood collected from cattle slaughterhouses. It’s such a rich source of nitrogen that gardeners have to be careful not to over-apply and burn the roots of their plants. Apply blood meal just before planting to stimulate green leafy growth.

Bone meal is finely ground bone. A by-product from animal slaughterhouses, it is a great source of calcium and contains up to 15% phosphate. Bone meal promotes strong root systems and flowering. It is often used when growing flowers, bulbs and fruit trees.

Shellfish fertilizer or shell meal is made from crushed bones or shells from crab or other shellfish. It is a great source of calcium in addition to phosphorus and many trace minerals. One benefit of shellfish fertilizer: it contains chitin which encourages the growth of organisms that inhibit harmful pest nematodes. (more…)

Herb Gardening 101

Herb GardeningHerbs have long been revered for both their medicinal and culinary value. They may cure colds, help you sleep and add flavor and zest to dinner. Fortunately for home gardeners, growing herbs is relatively easy. They thrive in just about any type of soil, do not require much fertilizer, and are not often bothered by insect or disease pests.

Defined as a plant without a woody stem that dies back at the end of each growing season, herbs were once considered a gift of the gods. Elaborate ceremonies and rituals celebrated their growth, harvest and use. Today, herbs are popular in many home gardens, where their leaves are utilized for flavoring and an entire plant may be used for medicinal purposes. (more…)

Gardening with Children

Gardening KidChildren love to play in the dirt. They like to search for earthworms and bugs. They like to create things. They like destroying things just as much. Watering plants, and anything else, brings great joy. Our little ones want to be part of the household and do some of the same things as mom and dad. Why not involve them in the garden?

Gardening with kids can be anything from planting seeds inside on a windowsill to caring for houseplants, to helping design and maintain a full-fledged garden. Big or small, growing projects teach kids to nurture seeds and plants — and thus themselves — and responsibility. They gain self-esteem and a deeper connection to the natural world. By prepping soil, sowing seeds and watching seedlings sprout, kids get important lessons in science and the environment without even knowing it. They might even want to eat the vegetables they tended to. (more…)

Grow Light Coverage

Light CoverageSupplying adequate light coverage for strong, healthy growth is critical to the indoor gardener. Using a light that is too small can result in uneven growth and weakened plants. Using too large a lamp can result in burn or other damage as well as wasted electricity. Deciding which High Intensity Discharge Light to use doesn’t have to be difficult. The size of your indoor garden will determine what wattage system you should purchase. The chart below gives general guidelines for the area coverage a particular lamp will provide. Plants such as tomatoes or basil that need strong, direct light will do best in the primary areas shown in blue. Most salad greens and other leafy plants including kale and spinach will find all the light they require in supplementary areas shown in white.

A number of variables including the type of reflector used, the reflective qualities of the grow room walls, and distance of plants from the light source will affect the amount of light that reaches your plants. The intensity of the light is greatest near the bulb and diminishes relatively quickly as the distance between source and plant increases. To avoid burning plants — HID lamps are also a source of heat as well as light — follow the chart to keep your lamp a safe distance from tender plant tops. You can generally determine if your plants are a safe distance from the lamp by putting the back of your hand level with the plants to test for a comfortable temperature. (more…)

Plant Propagation 101

Plant PropagationPropagating plants is an inexpensive and easy way to get new plants from plants you already have. This asexual means of reproduction produces a plant that is genetically identical to its parent.

There are a variety of plant propagation tools and methods; from taking cuttings to layering to dividing and more. The technique you select will depend on the type of plant you wish to propagate and the amount of time and effort you want to put into it.

Cuttings

One of the most amazing things about plants is that every cell has the ability to duplicate all parts and functions of the plant. By taking a cutting of a leaf or stem and creating the right conditions, you can create an entirely new plant (see Plant Anatomy Basics). (more…)

Let There Be Plant Light

Indoor Plant LightingIndoor plant lights let you shine a light where and when the sun don’t shine. They allow you to extend the growing season; have a year-round supply of fresh flowers, vegetables and herbs; as well as give your seedlings a head start before you can plant them outside.

There are almost as many kinds of grow lights for sale as there are different light spectrums. Everything from a simple $5 incandescent lamp to a sophisticated system using high intensity discharge (HID) lamps can help.

Here’s a rundown on what is available, how much it costs as well as the pro’s and con’s of different types of plant lighting:

Incandescent. Incandescent lamps lay at the low end of the pricing spectrum for plant lights. A good 150 watt bulb will only set you back about $5. You can get such bulbs from a local hardware store or a large nursery. An incandescent lamp can keep a small house plant growing, but isn’t necessarily your best bet for starting a large garden indoors. (more…)

Indoor Plant Care

Growing HouseplantsIndoor plants add color, texture and warmth to the home. They allow year-round access to gardening and can even improve air quality. Many houseplants are easy to grow, but they must be given appropriate care in order to thrive. Since your plants were probably started in a greenhouse — grown under ideal conditions — moving them into your home takes a bit of adjustment on their part.

Proper watering and lighting are the most important components of indoor plant care, but humidity and temperatures also play a role. The trick is to try to mimic the climate of the place that plant came from.

Tropical plants thrive in warm, humid environments, while cacti and succulents prefer hot, dry climes. Of course, your home can’t be everything to every plant, but you can take plant needs into consideration when choosing plants. And, with a few tricks, you can convince your green friends that they are living in their ideal environment. (more…)

Greenhouse Gardening 101

Greenhouse GardeningSo, you want to grow year round? Or maybe extend your gardening season? Interested in growing plants that normally don’t survive in your neck of the woods? If the answer to any of these questions is “yes,” then a greenhouse might be for you.

Hobby Greenhouses

A backyard greenhouse kit can provide a stable, warm environment where plants can be grown all year. They can also be used to get a jump start on the growing season, where plants, like tomatoes and peppers, are planted early and later moved out to the garden. Whatever your reason for wanting a greenhouse, there are several types, styles and costs for almost anyone who wants to start gardening under glass — or polycarbonate, for that matter! (more…)
