A concern that many of our home-owning clients bring to us is how they can achieve and maintain a lush green lawn, especially in the heat of the summer. The fertilizer that we stock here at Van Dongen’s is Agromart ‘Magic Carpet’ Fertilizer. We usually recommend the 25-5-10 formulation. What do these numbers mean, exactly?



Magic Carpet is a strong slow-release fertilizer. It is not diluted, but it is a slow-release nature prevents it from burning your lawn. The strong commercial grade wax coating (XCU= 65%) on the granules allows it to break down slowly over time, usually taking 6-8 weeks to completely dissolve. This means that you can overseed simultaneously without fear of burning! 



If you are overseeding or seeding a new lawn, good soil is very important. We have a specialty soil called Viva Lawn Repair, which is very finely screened. This soil contains peat loam, an important ingredient for germination of new seed.

Magic Carpet fertilizer is commercial grade that should be used every 6-8 weeks, whether you have existing grass or newly placed seed. You will require about 4lbs of Magic Carpet for every 1000 square feet of lawn you hope to fertilize. Our Magic Carpet bags are 25 kilograms (approximately 55 lbs). This means that a full bag will cover about 13,750 sq. ft.

Some spreaders use arbitrary numeric values rather than actual quantities. If this is the case, put about 0.4 lbs in the spreader (for 100 sq. ft.) and set the spreader to an estimated value. If all of the fertilizer is used up before the 100 sq. ft. has been covered, or if there is some left after you have finished the 100 sq. ft., try again until you have found an accurate setting. Then, keep note of this setting and use the previously mentioned 4lbs of fertilizer for every 1000 sq. ft.

If you are keeping the fertilizer for future use, keep in mind it should not be left in the spreader. If it is kept in its bag and in a dry area, Magic Carpet fertilizer can last for years.

Do you have dead patches of grass? Critters (skunks, raccoons) digging up your lawn? Do you see grubs in your garden?

Lawn grubs are the larval stage of June bugs, Japanese Beetles, European Chafer, Craneflies, etc. Nematodes are living organisms—natural parasites which are microscopic worms that occur naturally in the soil. Nematodes kill off grubs. It is 100% safe for people, pets, plants and earthworms.

Grubs start feeding on your lawn in April and then again in August. Application of the Nematodes are generally done in May or when the soil temperature is 10°C or higher. A second application should be applied in the fall (between August to October) to eliminate new grubs that may have hatched in the summer.

Nematodes generally control over 250 insect pests.

Most Nematodes are applied as follows:

• Nematodes are susceptible to the UV rays. Do not apply in direct sunlight (in the evening or on cloudy days are best).

• Water the lawn deeply (its best when it’s raining). Nematodes move easier through the soil when it’s moist.

• Keep your lawn moist for 10 days after application.

Nematodes have a cycle. We recommend that you do three applications as follows to get rid of your grubs:

• 1st application = May or June

• 2nd application= August or September or October

• 3rd application = Following year in May or June

These instructions can help you with any plant material no matter what size!

The overall key in the first year is to soak a plant’s root ball all the way through and then allow it time to dry out. The dry out period could last a few days and depends on a few conditions outlined in the paragraphs below.

It is common for cedars to “flag” – usually in late summer to early autumn. Cedar flagging is when tiny parts of the cedar’s foliage turn yellow, orange, or slightly brown – often in a very spotty or patchy fashion. This is very different than when a cedar actually dies.Read More
