Buying the Best Fertilizer for Flowers – Buyers Guide

Gardeners consider planting flowers in their backyard, regardless if it’s a small yard or a big one. It’s not too hassling to grow these, especially when you use the right fertilizer. However, looking for an exceptional one is not easy, especially when there are many options. You should consider this guide before buying one. 

 

Choosing What Type of Fertilizer to Buy

There are three typical types in the market, such as the following:

Granular Fertilizers

This fertilizer-type is effective if you apply it into the soil or sprinkle it around your plant. Most available fertilizers are in granules, and many gardeners prefer using this type because it can last a month or nine months. These need to break down first before the release of nutrients. Plus, it’s best to apply it before you begin planting. 

There are also high-tech granular fertilizers, and these have the slow-release advantage. Applying is not as frequent as other fertilizers. Also, it doesn’t provide excess nutrients, which can compromise other plants in your area. 

There are also organic granular fertilizers that use blood meal, feather meal, crab meal, cottonseed meal, and manure. You can expect natural minerals from this fertilizer-type. 

Powdered Fertilizers

This type is not very typical, but you can count on its effectiveness. It has the highest concentration, but the best thing about it is that you can control what you apply. The shelf life is long-lasting, which is why it’s also cost-efficient. Gardeners mix it with water in their watering cans during the application, which is not too hassling, unlike granular fertilizers. 

Liquid Fertilizers

This type of fertilizer concentrates that you have to mix with water before the application. Most gardeners use their watering cans or hose-end sprayer to apply it. The downside is that you’ll have to reapply this fertilizer every one to two weeks because of it’s nutrients’ longevity. On the bright side, plants easily absorb this fertilizer-type, which is an excellent boost during your plant’s growing season. 

Contains N-P-K

Considering your fertilizer’s nutrient contents is very significant, especially when you’re growing many colorful flowers. If you are going to buy fertilizers, make sure that it contains nitrogen, phosphorus, and potassium. 

You’ll notice packaging with a series of numbers, like 10-10-4 or 2-3-4. These are formulation, and it depends per brand. If you’re not familiar with it, it’s the amount or percentage of nitrogen, phosphorus, and potassium, respectively. 

  • Nitrogen

This nutrient is responsible for your plant’s growth. It functions as your plant’s backbone, and it’s crucial in the photosynthesis cycle because it can help your plant grow healthier. 

Nitrogen deficiency results in a lessening of chlorophyll content. It can also affect your plant’s fruiting, flowering, along with its protein contents. 

  • Phosphorus

This nutrient is handy during protein synthesis, as the growth of new plant tissues and cell-division. It stimulates the development of your plant’s roots, which deliver the nutrients that your plant needs after applying fertilizers. 

There’s phosphorus deficiency if your plants didn’t grow well, or it took time for these to mature. 

  • Potassium

The last nutrient from the N-P-K is also vital because it promotes the proper functionality of living cells. Plus, it aids starch and protein synthesis in plants. 

A deficiency sign is when leaves are starting to turn yellow, or the margin is falling off. 

  • Other Nutrients

Aside from the N-P-K, there are also other important nutrients that your plant should have. 

  • Magnesium is important because it’s responsible for providing the green coloring of your plant. 
  • Calcium contributes to the development and growth of your plant’s cell walls. This nutrient can make a plant disease-resistant. Plus, it’s essential for metabolism. 
  • Sulfur can also help your plant in resisting damages while contributing to its growth. Also, these are handy in the production of proteins, enzymes, vitamins, and amino acids. 

 

Complete Fertilizers vs. Organic Fertilizers

Most gardeners are having a hard time choosing whether they need to use complete fertilizers or organic ones. Before, people prefer organic fertilizers because the ingredients are safer. However, gardeners nowadays focus on the nutrient contents, which plants need more. 

Complete fertilizers come with the three significant elements that plants need to flourish. These are nitrogen, phosphorus, and potassium. These are important, especially phosphorus, because this nutrient promotes blooming, which flowers need. In planting flowers, it’s best to get a fertilizer with higher potassium and phosphorus. 

Organic fertilizers compose of fish emulsion, animal manure, leaf molds, which come from living things. Other fertilizers contain greensand or rock phosphate, which come from non-living things. 

The best thing about this kind of fertilizer is that it supplies nutrients too, and it can also enhance your soil. These will not burn your plants, and it stays in your soil for a longer time. Plus, it can strengthen your plant’s immune system. 

Slow-release Fertilizers

You’ll also stumble on fertilizers with slow-release advantages, and it’s ideal if your plant needs infrequent application of fertilizers. These include slow-acting organic fertilizers, like insoluble mineral fertilizers. Most organic fertilizers are slow-release since you need organic matter to decompose soil microorganisms. 

As you search for fertilizers in the market, complete and organic fertilizers are both parts of the recommended list for the best fertilizers for flowers. 

 

Understanding What Annual and Perennial Flowers Are

Before you choose what fertilizer to buy, you should know what kind of flowers to plant. Here’s a quick overview of what annual and perennial flowers are. 

Annuals

This type grows and dies in one season, yet some drop seeds tend to grow in the spring. It typically blooms all season and ends in frost, which assures showy blooms and consistent color. Plus, you can plant these any time to refresh your plant beds. 

Perennials

This type grows for many seasons. The top part of your plant will die in the winter season, yet there will be new growth during spring, as long as it’s the same root system. However, these have less bloom. 

You’d be surprised to know that some annual flowers can be perennials when you’re in a warmer climate. Deciding what to plant also has something to do with your area’s climate. 

Some Tips for Beginners in Planting Flowers

Planting flowers is not very hassling, yet you’ll find these tips helpful if you’re a newbie. 

Prepare your pots or garden beds.

Ensure that you dig out in advance and mix in your fertilizers to enhance your soil’s structure. Pull the weeds out, too, so these will not compete for nutrients and water once you start cultivating your plant. 

Keep your plant size in mind

Check the description or tag to know how wide and tall your plant might grow. Proper spacing is crucial, and you need to put tall flowers at the back, so it doesn’t cover smaller ones. 

Buy healthy plants

If you’re thinking of buying from a nursery, you should look for a plant that appears green and strong. Don’t buy brown, messy, and wilted plants, and if you notice that pots are bone-dry, don’t buy these as well because it’s probable that those are stressed plants. 

Focus on planting times for seedlings

If you’re planting seeds, it’s best to read the package to know how deep you need to plant these. Also, you need to check on your plant’s maturity days. If your plant needs 80 days for maturity, yet it’s the end of June, your plant may grow but not bloom. 

Remember to water your plants

Most plants need moisture weekly to grow, regardless if you’re planting perennial or annual flowers. You can stick your finger in the soil to know if it’s dry. You need to check the ideal way to water your plants because some require deep watering, while some don’t. Plus, you’ll need to water your plants daily during summer to hydrate these. 

Mulching is necessary for new plantings

Mulching is crucial because it can lessen evaporation. It will let you water plants less frequently, saving a lot of effort without compromising your plant’s health.

Nasturtiums

Some Reasons Why Planting Flowers Is Worth Your Time

Gardeners plant flowers because these have many advantages. It’s not only for improving your garden’s view but also for other benefits to other plants. Here are some reasons why it’s advantageous. 

Enhanced pollination and harvests

When you have flowers in your yard, these can draw honeybees, along with other pollinators. You can attract wasps, birds, native bees, and butterflies, producing more yield. If your plant is a self-fertile crop, your chances of increasing the yield of other plants surrounding these are high. 

If you’re growing citrus plants, zucchinis, eggplants, or berries, it’s best to plant flowers. Insects will help you with pollination, distributing these to nearby fruit or vegetables. 

If you have deep-throated flowers, these can also work as a reservoir because these can hold dew drops, which pollinators consume for better pollination. 

Helpful in managing weeds

Weeds are also problems that gardeners experience, and thanks to flowers, you can manage these. If you’re planting flowers as a space filler or a ground cover, these can shade your soil until these beat weeds. Some flowers grow quickly, leaving no room for weeds to grow. Some of these include alyssum, native violets, and nasturtiums.

Helpful in disease and pest management

Aside from weeds, you can also count on flowers when it comes to disease and pest management. These keep an exceptional balance, which is significant in the health of vegetables or fruits. 

Flowers can attract predator insects. Instead of compromising your vegetables or fruits, these insects will go to your flowers’ pollen and nectar. There is lesser work for you in controlling these pests because these see your flowers as pollen instead of your crops. 

Flowers can produce chemicals, too, and these can repel undesirable insects from compromising your plant’s roots, leaves, and fruit. You can plant some marigolds or nasturtiums because these flowers can disinfect your soil. Thanks to their strongly aromatic flowers, these can repel pests above your soil. 

Aside from that, flowers can serve as a trap to bait pests. It’s an easy way for you to remove these, making it an effective way to protect your plants. 

Flowers are edible and nutritious too

Flowers are not only for garnishing. There are edible flowers that you can plant, and you can include these in your diet. These are very nutritious, and some gardeners eat blue borage, violas, cheerful calendula, nasturtiums, and pretty pansies. The petals of these flowers will give you added nutrients as you include these in your meals. 

Aside from that, seeds from flowers are also edible. Chia flowers, coriander, and sunflowers have protein-rich seeds. The best thing about these is that they are easy to grow. 

You can also make herb teas from flowers. Some of the flowers that you can plant are lemon balm, borage, bergamot, and chamomile. If you have a big yard, you can start your small tea business in your neighborhood. 

Provide medicinal benefits

Numerous edible herbs can also provide health benefits. Thanks to the nutrient compounds these edible herbs have, you can use these as antibiotics. Plus, these can also boost the immune system of your body.  

You can use flowers as ingredients

Flowers are handy if you’re making cosmetic products. Petals from the Calendula-plant are useful in making lip balms and salves. 

Provide natural and pleasant aroma

You’ll save a lot of money in growing flowers because these can provide pleasant fragrant blooms in your home. Your garden will look not only very attractive but also stress-relieving.


Conclusion

Flowers are always part of the plants you’ll see in every gardener’s yard.
