March Fertilizing Tips

Here at Plantland we are looking out our windows with Spring-tinted glasses, are you? We wanted to share with you some pre-Spring planning ideas that are on our mind to inspire a  little Spring Fever in your garden as well. 

Now is a great time to start feeding those poor dormant plants in your garden. As the winter snow and rain drains into the soil, it will transport the fertilizer through the soil and to the roots, getting your plants off to an early start when Spring has finally arrived.

 You may be wondering which fertilizers are best for the different plants in your yard. To help you make the right fertilizer choices, and to maximize value with correct application, here are a few general rules, from the brilliant Ed Hume, who’s seeds we have in our store:

• Evergreen trees and shrubs, including rhododendrons, camellias, azaleas, juniper cypress and broad-leaf evergreens, are fertilized with a rhododendron-type fertilizer.
• Deciduous trees and shrubs, which includes fruit, flowering and shade trees, roses, lilacs, forsythia, etc. are all fed with a rose or general garden-type fertilizer. Deciduous refers to trees and shrubs that lose their leaves during the winter.
• Perennials, annuals and vegetables are also fertilized with a rose or general garden fertilizer.

Of course there are exceptions to this rule, but they are few and far between. You can do most of your plant feeding with these two basic types of fertilizer.

There are several rules you must observe when applying fertilizers.

• The first one is critical - READ THE LABEL before you apply any type of fertilizer. Application times, amounts and conditions must be followed to the letter. In other words, only apply as directed on the package.
• Second, most fertilizers should not be applied to dry soils, as the material is apt to burn the surface feeder roots almost instantly.
• Third, all of the dry-type fertilizers should be watered-in thoroughly, immediately after application.
• Fourth, it is important to apply the fertilizer out at the drip-line of the plant, as this is where the feeder roots are located. If you spread the fertilizer up under the plants, you are apt to burn the tender surface roots.
• As you apply the dry fertilizer, keep it off the leaves of your plants, spreading it on the soil only.
• Distribute the fertilizer evenly around the base of the plants. Avoid concentration in any one area.

Here are a few basic tips for fertilizing the various types of garden plants:

• Large Trees and Shrubs - By perforating the surrounding soil area to a depth of twelve to eighteen inches and spacing the holes about two feet apart, you can get the fertilizer down to the roots of established trees and shrubs. Water thoroughly after applying the fertilizer. An added advantage to this method of feeding trees is that it encourages the roots of the trees to grow deeper into the soil. 

• Rhododendrons, Azaleas, Camellias, Junipers, Evergreens, etc. - Use a rhododendron type of fertilizer when feeding these types of plants. Most should be fed twice a year, once in March and again in June. Be careful not to spread the material up under the plants, as it is apt to burn the surface roots; instead apply it at the drip-line of the plant. Follow application directions on the label of the fertilizer you use.

• Annuals, Perennials and Roses - Both the annuals and roses will do best if they are fertilized on the average of once a month throughout their growing season. Perennials should be fed in spring and again in the summer. Use a rose or general garden fertilizer to feed them.

• Vegetable Gardens - Use a general all-purpose garden fertilizer or a rose-type for feeding vegetable plants. Mix fertilizers into the vegetable garden soil prior to planting. Established garden vegetable plants are side-dressed with fertilizer during their growing season. 

• Planting of New Shrubs, Trees, Annuals, etc. - Use one of the specially prepared planting or transplanting fertilizers at planting time. These fertilizers are mixed into the soil according to the directions on the label of the brand of fertilizer you use. The greatest advantage of a planting or transplanting fertilizer is that they encourage root growth, thus insuring better top growth as the plant develops.

You can get your garden plants off to a good start and keep them growing well by feeding them properly, with the correct type of fertilizer.
