Feeding your Lawn
The amount of fertilizer for any particular lawn depends on the fertility of the natural soil, the degree of growth you want, and the type of grass that you are growing.
Fertilizer applications are determined by the amount of nitrogen they contain, because nitrogen is the most difficult of the three materials to handle. We recommend any special turf type fertilizer made by a reputable manufacturer using a controlled release nitrogen. This will provide you with a well balanced feeding for your lawn and the fertilizer will release slowly. You should apply about half the annual amount in the spring, and the remaining half in the early summer and fall. Be sure to follow the instructions on the bag. Always water the fertilizer to prevent burning.
Mowing your Lawn
Mowing is one of the most important operations in the maintenance of a fine lawn. Proper mowing will make a good lawn look better, improper mowing can ruin a good lawn in just a few weeks. The most important point to remember is to keep the mower blades sharp. Nothing defaces grass more quickly than a dull mower. Remove all objects from the lawn before you mow, to prevent injury to others, and to prevent damage to the mower.
Don’t let your lawn grow so tall that it falls over, for it will be difficult to mow and it will smother out.
Never remove more than 3 cm of the leaf height at any one time. We recommend mowing of Bluegrasses and Fescues at a height of 4 cm. You can determine the height of your mower blade by placing it on a driveway or sidewalk, and measuring the distance between the blade and the sidewalk.
You should remove clippings that clump so that they don’t smother the grass.
Watering your Lawn
In the summertime, lawns generally require about 25 mm. of water every week. Bluegrass, however, does go dormant during dry seasons – the grass may turn brown, but will green up again when it is watered.
A good rule to follow is this: If you water, do it regularly. Apply 25 mm. every week (including rain) at one setting of the sprinkler. Water evenly and slowly enough so that it penetrates without run off.
Too much water can be as harmful as not enough. Soil that is continually soaked does not allow air to reach the root zone where it’s required. Avoid frequent light waterings which result in shallow rooting.
The best weed control is a good, healthy turf. When your lawn is thick and vigorous, weeds simply have no place to get started . . . and you have no problem. In renovating lawns, however, or even in established lawns that have had lapses in maintenance, weeds do have a way of intruding.
Killing the weeds is only half the operation – you must remember to replace them with grass.
Healthy turf will withstand infestation and recover faster than neglected turf. Here are some guides for healthy turf:
1. Your lawn should be fertilized 4 times per year. Our staff would be happy to help customize a program for your lawn or you can use the program in How To Fertilize
2. Mow before the grass gets too tall
3. Cut no more than 3 cm of the leaf surface at any one time.
4. Keep your mower sharp.
5. Don’t allow clippings to accumulate to the extent that they form a mat.
6. Remove thatch as required.
7. Avoid frequent waterings which tend to keep the grass wet.
Relieving Compacted Turf
Relieving compacted turf Soil compaction is a problem which develops naturally under many conditions. Heavy soils and heavy traffic zones are particularly subject to compaction. If soil is trampled, especially when it is wet, compaction will very likely occur.
To relieve compaction without excessive injury to grass plants has been a formidable chore until recent years when power driven aerators were developed. Today, aerators of many types and sizes are available.
If you are an average homeowner, you may not want to invest in aeration equipment. You will be wise, however, to give your lawn the benefits of aeration. Call your landscaper or garden centre for information on lawn services or rental companies that have appropriate units.
The gratifying results achieved from aeration – plus the savings realized in water and fertilizer, will easily justify the cost.
Renovating Worn Turf
Turf renovation through use of vertical mowers and aerators was once largely limited to golf courses and athletic fields. Now, it has become a common practice for other turf areas, including home lawns.
Fall renovation is in order where it is practical to renew or rejuvenate turf that has been abused but it is still in reasonably good shape. Since roots grow best in the Fall and early Spring, loosened soil and fertilizer are most needed at these times to encourage turf growth.
The best practice, of course, calls for a continuous management programme to prevent deterioration to the extent that it requires renovation. Such a programme would include: elimination of compaction; application of fertilizer and moisture as grass needs it; and good weed control practices.
Thatch and Thatch Control
Thatch in turf is the accumulation of old leaves, clippings, stems, roots, and other organic material which has failed to decay. Thatch sheds water rather than letting it percolate into the grass root zone. It may harbour fungus and other diseases, as well as insect pests, and may make fertilizer applications ineffective
One of the answers to the thatch problem is a vigorous raking. This is difficult to do by hand. A much easier way is to use a powered vertical mower which is self-propelled and equipped with hardened steel blades. It cuts out the thatch and thins matted growth. If desired, you can set the blades low enough to touch the soil; the scarifying action is an ideal pre-seeding treatment for bare or thin areas that need over-seeding
Unlike diseases, which must be prevented, insects are usually controlled after they appear. It is important that you recognize them quickly before they do too much damage.
A common insect that you should watch for is the white grub. Grubs live in the soil under the grass. If you suspect their presence in your lawn, remove a block of sod and count the grubs. If you have as many as five per 1/10 sq. metre you are infested. Nematodes are an organic aid in controlloing these insects.
The sod web worm is a lively brown worm about 2 cm. long that feeds on grass and causes grass to turn brown. Chinch Bugs are small black insects about 1/2 cm. in length that suck the juices from the grass plant. The damage shows large irregular yellowish brown patches, usually along the edge of a sidewalk, curb or foundation.
