Organic Fertilizers for Your Home

Organic garden fertilizers consist of decomposed plant and animal compounds that are broken down by microbes into a form that living plants can use, usually dissolved in water and taken up through the roots. They are naturally occurring chemical compounds, unlike chemical fertilizers that are compounds created in a lab. Some organic fertilizers contain mostly one main nutrient, for example bat guano has high nitrogen content and very small amounts of phosphorus and potassium. Organic fertilizers also contain other nutrients and trace elements. When you select an organic fertilizer, you need to know where it falls on the N-P-K range so you know on what plants it should be used and when in the plant’s life cycle it will offer the most benefit.

What makes good fertilizer?

“N” = Nitrogen, “P” = Phosphorus, “K” = Potassium.

Represented in that order, these are the numbers you find on fertilizer packages. 10-5-5 is an example.

Some plant based organic fertilizers are Compost, Humus, Alfalfa meal, Cottonseed Meal, Corn-gluten meal, Soybean meal, and Kelp/Seaweed products. Check labeling information to be sure that the source plants were raised organically. Some meal crops such as cotton are heavily sprayed with pesticides, and traces of the poisons may be retained in the meal. Compost and humus should be finished, soil-like products when applied to your garden.

Animal based organic fertilizers are Manure, Guano, Blood meal, Bone meal, and Fish Emulsion products. Guano may come from bats or seabirds, and is available in pellets or dried powder. Its high nitrogen value makes it quite potent, and it can easily burn plants if not used properly. Fish emulsion is my personal choice, because it is diluted and used when watering plants, or it may be used as a foliar feed. Fish emulsion is gentle enough even for tiny seedlings. It provides all the nutrients they need for a strong start, and is well-rounded enough to use all season. Blood meal is the dried and powdered blood from slaughterhouses, and is a real benefit for green leafy vegetables. Some people say that blood meal attracts dogs; it is also known as a deer repellent. Bone meal is powdered bones and is very high in phosphorus and calcium. Root crops benefit from bone meal, as do flowering bulbs and roses. Broccoli is one vegetable that is reportedly high in calcium, and the only way broccoli plants can get calcium is if the soil they are grown in contains calcium. I dust bone meal in the soil when I set out broccoli plants, and I feel like it increases the health value of my broccoli by increasing the calcium content.

Plants also need minerals. Most mineral fertilizers contain additional micronutrients. Epsom salt is a very good source of magnesium and sulfur. It can be used directly in the soil in granular form, or you can dissolve one Tablespoon of Epsom salt in one gallon of water and spray it on plants for a foliar feeding. Tomatoes, peppers, and roses will really respond to Epsom salt feeding. Greensand, Gypsum, Hard-rock phosphate, Soft-rock phosphate, and Limestone are other mineral fertilizers. A soil test should be done before you add mineral supplements, since some can affect the pH balance of the soil.

Air Condition Your Garden

July, it is the time of the year when air conditioning is as important in the garden as it is in the home. You, as the temperature rises, can cool off with an electric fan, a cool drink or by hiding away in a cool spot. Your plants are not quite that lucky; yet certain gardening techniques can be employed to help your plants through the summer months. The benefits of air conditioning in your garden will show up in the form of increased production, greater resistance to disease and pests and, in general, a more attractive vista. An improper over-heated environment during the warmer months often leads to wilt, dropping of buds and yellowing of foliage. Aeration of the soil is concerned with its exposure to the air. If this is lacking then your plants very likely will suffer this summer. Believe it or not but there are millions of tiny spaces between the soil particles and this is where air resides. Soils that become water-logged force out this air, a condition that leads to souring of ...

Harvest and Store Garden Vegetables

Vegetables gathered at just the right time can be stored naturally or, in many cases, by deep freezing, for use months later in the kitchen. Nature, however, makes its own provision for over- winter storage and the survival of the species, which involves either the production of seed (peas, beans, etc.) or roots to remain in the ground to produce seed heads the following season (parsnips, carrots, etc.). Vegetables in this latter group store much better if left in the ground and lifted as required, or stored in clamps. parsnips can be left in the ground throughout the winter Root crops should never be stored in plastic bags, for they will invariably rot. If you have well- drained soils, where slugs are not a problem, a winter hardy variety of carrot such as ‘Autumn King’ is best left in the ground; carrots stored in sand or peat often shrivel, rot or go moldy. Parsnips are certainly best left in the row; frost improves the flavor but it is a good idea to lift a few at a time during...

Growing Your Own Rhubarb: Growth and Cultivation

Rhubarb is commonly eaten as though it is a fruit, although in fact it is a perennial vegetable. It is simple to grow, produces a good crop, and if tended with care, can last for up to twenty years. It prefers either full sunlight, or partially shaded areas. Varieties of rhubarb include ‘Victoria’, ‘Cawood Delight’, ‘Ruby’, ‘Champagne’, and Timperley Early’. Planting Out Your Rhubarb Rhubarb can be planted out in sets/crowns anytime between November and early April, and can survive temperatures as low as minus fifteen degrees centigrade, as it is virtually frost resistant. The sets are usually around 10cm in diameter. Before planting, ensure that you have a clear, well-weeded, open patch of well-drained soil, and that the soil is well fertilized. Dig down between two and three ft deep, place the set into the hole, cover with soil, gently firm out the surrounding soil, and ensure that the rhubarb is watered well. If you are planting more than one plant, you must space them approxima...
