Why Did We Like It?

To begin with, this product consists of earthworm castings, kelp, bone meal, and feather meal that would be an excellent feed for the microbes in the soil. These are good bacteria that initiate growth and ensure proper root development.

Another great advantage is that it will provide the soil with continuous release feeding, which lasts up to 3 months. You have to apply it once every 12 weeks, and the plants should grow well. So, even with a busy schedule, maintaining your blooms should not be an issue.

It is also effortless to apply, and you will be able to do it directly from the pack. Just make sure that you read the instructions carefully and pour in the exact amount. One should be very careful with this as excess amounts of fertilizer can severely damage the roots.

What Could’ve Been Better?

Although the pack says that it increases water efficiency, we found that it needs a lot of water to survive well. This is because the formula is pretty concentrated, and you will have to spread it evenly throughout the plant bed. Water helps in doing that, and hence you should water it regularly in the beginning.

2. BioAdvanced 701700B

One of our top recommendations is the BioAdvanced 701700B, which is known for its unique blend of ingredients. If you have an infestation problem or simply want your lilacs to grow well, this will be the perfect solution. Read on to know more about it.

Why Did We Like It?

First of all, it is incredibly versatile and targets a variety of pests. From adult beetles to leafminers, fall webworms, adelgids, and caterpillars, it removes them all efficiently.

Once you apply this, there should be no new infestation in the next 12 months. It stays in the soil and will keep it healthy for your flowers to grow well.

Now, if you are wondering what will happen if it rains, do not worry at all. This is absorbed by the roots and is stored internally by the plant. In the first 12 hours, the absorption is completed, and after that, it will not be affected by heavy rain or irrigation. Your plants will be well protected, and the effect will continue for the whole year.

Also, it is very easy to apply; a measuring cup is present inside the package, which will help you determine the exact amount. Read the instructions provided carefully, and you should not face any problems.

What Could’ve Been Better?

The only issue we faced is that the lid was tough to open. It may seem very trivial, but when you are actually working, it does seem to be a hindrance. We had to open it with the help of pruning shears. But once you open it, it is pretty easy to use.

3. Osmocote 277160 Smart-Release Plant Food

If you are looking for good plant food, which will provide your lilacs with all kinds of nutrients? The Osmocote 277160 Smart-Release Plant Food is an excellent choice and will ensure vigorous growth. We had seen our lilacs bloom like never before after we started applying this product.

Why Did We Like It?

The pack consists of granules that are coated with a semi-permeable resin. This makes it easy for you to apply. Scoop 3 spoonfuls and mix it with the top layer of the soil. You can use a sharp object to dig into the soil, and once you are done, water it well.

This brings us to the second benefit of the item. Once water is poured, the shells allow it to permeate and dissolve the nutrients inside. Nutrients then come out and mix with plant roots, while the coating remains in the soil.

Further, we loved the mixture of nutrients and the benefits that it had on our soil. It worked very well for the roots, and we found the plants growing at an impressive rate. It is not only great for lilacs but also for other vegetables. So, you can pour it throughout your garden or farm without any issues.

What Could’ve Been Better?

The white shells do not dissolve and will stay in the soil. Ideally, you should clean them up as they remain very visible and look odd. We found it very time-consuming because each one had to be picked up separately, and it was indeed a tiring job.

4. Dr. Earth 707P Bud and Bloom Booster

If you want your flowers to be blooming for a longer period, the Dr. Earth 707P Bud and Bloom Booster will help out with it. Made with a host of rich ingredients, it will make sure that you have a beautiful garden to flaunt to your guests.

Why Did We Like It?

This is a blend of fish bones, feather meal, alfalfa, and soft rock phosphate along with mined potassium sulfate. The mixture is extremely nutritious for plants of all types. They dissolve very easily and will feed the plants for almost a year.

We also noticed that the mixture did not contain any kinds of impurities and sewage. It had no chicken manure or GMO making it entirely organic and natural yet devoid of impurities.

Besides, if you have pets in the house, you might be worried about the fertilizers affecting them. Well, these are absolutely safe to use with kids and pets alike.

Lastly, we found the lilies to be blooming better than before. The leaves were greener and shiny, while the flowers had a rich color. We could see and tell the difference, and hence we were delighted with it.

What Could’ve Been Better?

The only drawback to this product is that it does not smell good. Yes, the flowers were blooming very well, but it would smell really bad initially. The smell disappears with time, and we would recommend you apply it several days before having anybody over.

5. Bonide 811 Copper 4E Fungicide

We are almost halfway through the list, and it is time to introduce the Bonide 811 Copper 4E Fungicide. This is known for its versatility and is designed to keep your garden healthy. If you are a gardening enthusiast or a DIY gardener, this could be an incredible product to use.

For anybody who has a large garden with big trees or a dense but decorative one, these are common issues that may affect your plant’s life.

This fertilizer promises to keep your fruits, roses, ornamental turfs, and herbs safe and protected. It is also safe for humans and pets and will not cause any health problems. You can use it efficiently till the day of harvest.

If you are wondering about the crucial ingredient that provides this fertilizer with an extra touch, it is liquid copper or copper octanoate. This is a natural element that provides a huge number of benefits to your plants.

Lastly, it is very easy to apply, and it mixes with water immediately. Apply it with the help of a hose-end sprayer and make sure that you follow the instructions given carefully.

What Could’ve Been Better?

If you have painted wood or vinyl siding in your garden, make sure that the formula does not touch it. It can leave a lasting impact and cause discoloration. So, we would recommend covering any such surfaces before you start with the job.
