Preparing Soil For Bulbs And Fertilizing Bulbs

Preparing Soil For Bulbs And Fertilizing Bulbs

Even though bulbs store food for themselves, you need to help them out at planting time for best results by preparing the soil for bulbs. This is the only chance you get to put fertilizer below the bulb. In order for the bulbs you plant to make use of food available in the soil, you need to start with healthy soil. Then, you need to know when to fertilize bulbs after that.

Using Fertilizer for Preparing Soil for Bulbs

For fertilizing bulbs, fertilizers can be inorganic which means they are chemically treated or laboratory created. They can also be organic, which means they came from natural or once-living sources.

Your plants won’t care which one you use, but depending on your beliefs, you can choose the type that best fits in with your feelings on the issue. Inorganic fertilizers are more readily available, but be careful when using these, as fertilizing bulbs with inorganic fertilizer can burn roots, the basal plate, or even the leaves if the plant comes in direct contact with the fertilizer.

Fertilizers come in granular or liquid form and are easy to apply at planting time. Granular fertilizers are better because they don’t dissolve as quickly. They remain in the soil longer, and the longer the better.

Nitrogen is important for preparing the soil for bulbs to be able to start their leaf growth. Phosphorus and potash are good for overall health, resisting disease, root growth, and flowering. You will find the proportions on the side of the fertilizer bag or bottle listed as N-P-K ratios.

Remember when fertilizing bulbs, not to over-fertilize and never increase an application above the directions on the container. This can damage or even kill the plants.

In order to apply the fertilizer, mix the granular fertilizer with the soil at the bottom of the planting holes. If you’re using inorganic fertilizer, add a layer of unamended soil to the hole as well because you want the bulb to sit on fresh soil rather than come in contact with any of the fertilizer.

Adding Organic Matter for Preparing Soil for Bulbs

Organic matter is used when preparing the soil for bulbs to improve the soil by improving low fertility, poor water-holding sandy soils, and fertile but poorly-draining clay soils. When you add organic matter to your soil, remember it gets used or breaks down each year and has to be replenished annually.

It’s easier to amend the soil when you first dig up the garden before planting each year. This way you can layer on about 2 inches (5 cm.) of organic matter and work it in well with what soil you had. In future years, you can simply apply the organic matter as mulch and it will work into the soil below.

When to Fertilize Bulbs

In subsequent years, when flowering might be diminishing, you will need to be fertilizing bulbs in your garden. The best time when to fertilize bulbs is to wait until the bulb’s leaves are well out of the ground and then fertilize at half strength. Then, once the bulbs have finished flowering, you can fertilize once more. A third feeding would be okay two weeks after the second feeding, again at half strength.

Half strength is easy to figure out. You would just double the water or halve the fertilizer. If the label suggests 2 tablespoons (29.5 mL.) to a gallon (4 L.) of water, either add 1 tablespoon (15 mL.) to the gallon (4 L.) or 2 tablespoons (29.5 mL.) to 2 gallons (7.5 L.) of water.

You can fertilize summer flowering bulbs the same way you would any other perennial in the summer garden.

Remember that fertilizer is only available to the plant when there is water available to transport the nutrients up the roots from the soil. If there is no rain, be sure to water the bulbs as soon as they are planted and continuously through the growing season when it’s not raining.

Fertilizing your garden is a great way to improve the soil and ensure your plants grow well. Commercial fertilizer can be expensive and full of harmful chemicals that are toxic for the soil. You can fertilize your garden cheaply, and naturally, by using food products and plants. You can also use animal products as natural, cheap fertilizer.


How to Fertilize The Soil at Home

Thegardengranny.com – Having a beautiful and fertile garden is the dream of garden owners. Beautiful gardens make us even more excited to take care of them and plant our plants in the garden. Therefore the beautiful garden can not be separated from the influence of existing soil conditions in the garden. Fertile soil makes beautiful gardens and plants that you grow increasingly flourish. Conversely, if the land that you have is arid and infertile, then plants are also difficult to grow on land like that. In this article we will share a number of ways to make your land fertile and can be planted with plants such as vegetables, flowers and so on.

Fertilize the Soil Using Water

Dry soil indicates less fertile soil. Because dry soil has little water content, water content is very determining whether the soil is fertile or not. If you find land like this, water it regularly. By regularly watering the soil, at least the soil does not dry out, and life there can grow like worms and other microbes.

Use Dolomite Limestone

In addition because the dry soil makes it infertile. pH levels also affect soil fertility. Soils that have high pH levels show high acidity too. High acidity is dangerous for plants because it can kill plant roots. To reduce the acidity in the soil, you can use dolomite lime. Lime’s alkaline nature can make the soil’s pH drop. Just sprinkle on the surface of the soil and water with water to absorb.

Use Compost Fertilizer

Apart from lack of water and high pH, soils that lack nutrients can also experience infertility. Soil like this cannot make plants grow properly because the nutrients needed by plants are inhibited or even not available. That way plants will easily die. For this reason, the use of compost is needed so that the soil returns to produce nutrients needed for plant growth and development.

Increase Soil Porosity

Increasing soil porosity is also able to make the soil more fertile. This is because the soil will easily absorb water. You can use a combination of soil with large and small particles to make the soil more easily absorb water.

Add Fine Rocks

The next way to make the soil more fertile is to add fine rock around your garden. Fine rocks such as phosphate contain phosphorus, calcium, carbon and minerals needed by plants. These minerals make the soil more fertile because the soil will meet the mineral requirements for the plants you plant. You can also use a combination of these rocks with compost to get maximum results

Reduce Chemical Fertilizers

To make the soil fertile, fertilizers with chemicals are very effective. However, these fertilizers have a negative impact after you use them. Chemical fertilizers make soil that after being fertilized becomes hard and has a high pH. This makes the soil infertile after several planting and harvesting. Stop using the chemical fertilizer and start using compost. Making compost is also very easy, you can make it yourself at home.

Keep the Soil Composition Soft

Making soil fertile by keeping the soil soft and not allowing the soil to get too hard is very important. Solid soil makes the soil pores not open and the life of microorganisms in the soil to be reduced. By making the soil loose, water and air easily seep into the ground. So good microorganisms make the soil fertile and full of nutrients.

So several ways to make the soil in your home fertile. Fertile soil provides many benefits for you. If you want to do gardening or just plant fertile soil flowers it is certainly necessary. You don’t want your house to look arid, no trees, right? Hopefully this article is useful. Don’t forget to always update other interesting articles here.


Your Soil Is Unique.

Remember, your soil is unique to you. What someone across the country or even across the county needs to do with their soil, may not be best for your garden. Get to know your soil. Take good care of it and it will give you a lifetime of growing great, healthy, nutritious food. Just what your body needs.
