How to Produce Beautiful Blooms
Roses that are fed properly will produce spectacular flowers. Taking care of roses is easier than you may think – just about anyone can grow them successfully. However, to grow absolutely stunning roses, I highly recommend being careful of the fertilizer you choose. Only the best fertilizers with the right N-P-K ratio and quality ingredients will lead to knock-out roses.
Let’s look at a couple factors that you may want to look into when making an educated decision on deciding on a fertilizer to buy
A general rule of thumb when looking for the right fertilizer is to look for a good N-P-K ratio. N-P-K stands for nitrogen, phosphorus, and potassium, respectively. See my in-depth nutrient guide for more information. Different plants require different levels of each element. Generally, an N-P-K ratio of 1-1-1 is recommended for roses.
Organic vs Non-organic
Nowadays, the market is filled with both organic and non-organic chemicals in fertilizers. Non-organic fertilizers tend to deliver the correct nutrients, but do very little by way of helping the soil. Organic fertilizers on the other hand may not only give your rose nutrients, but will also help with soil quality.
Not only is using the proper fertilizer important, but also is how well you nourish the rose’s root zone. For the best possible conditions for the plant and to prevent root disease, it is important to make sure the soil is drained completely and does not always remain damp. Excessive moisture can actually lead to root disease.
When you are watering your roses, try to avoid getting the foliage wet. If the foliage gets wet, it puts your rose bush at an increased risk of developing diseases such as black spot and powdery mildew. To avoid this, use soaker hoses. Soaker hoses will direct water directly into the soil around the rose and thereby make it easier for you as well as will minimize water on the leaves. Also, try to water in the morning. When you water in the morning, the rose bush has the afternoon sun to dry off. Stagnant water will not just be sitting around on your bush’s leaves.
As we all know, sun is vital to plants because it allows them to undergo photosynthesis and create the energy they need to remain in homeostatic balance. I recommend that you allow your rose to receive at least 6 hours of sun per day.
Get Rid of Pests
If you see any pests, try to act fast to get rid of them. Pests can be extremely detrimental to your rose bush.
One notorious bug is the Japanese beetle. When you spot one, there are sure to be many more around. They will infest your rose bush and “skeletonize” your bush’s leaves. Get rid of them as fast as possible for they wreak havoc on your garden.
Types of Roses
There are many types of roses including modern garden roses, climbing roses, English roses, floribunda roses, grandiflora roses, groundcover roses, miniature roses, hybrid tea roses, rambling roses, and polyantha roses. You may want to do some research to see which rose bush you like the most.
Additional Rose Tips
Here are some additional tips for growing absolutely beautiful rose bushes. Please note that this is not a video that I have created, but rather one that I found that shows some good tips.
Get the best fertilizer possible…it’ll save you many headaches (trust me). I recommend buying the Osmocote Outdoor Smart Release. Don’t fall for false marketing or convenience by buying any old fertilizer from your local gardening store. Many of them will simply not produce the same results.
