1. When should I aerate my lawn?

In Maryland, the best time to aerate is in late August or early September when the grass is coming out of its summer dormancy.  Lawns should be aerated when the soil is slightly moist, typically a day after rainfall or irrigation.

2. What is core aeration?

Lawn Core Aeration is the simple process of removing small cores of soil and grass to allow air, water, and nutrients into the root zone.  Core aeration is more effective than spike aeration where small holes are punched in the lawn using spikes.

3. What is a xeriscape?

A xeriscape is a design with low-water-usage plants.  It is most widely used in the southwest U.S., but is gaining popularity throughout the country.

4. What is low-maintenance landscaping?

Low-maintenance landscaping is what it sounds like, and refers primarily to the very minimal fertilization and trimming that are required, if any.  Although all landscapes have to be maintained to some extent, this approach is becoming more and more popular as environmental concerns increase.

5. How often should I water my lawn

Depending on temperature and time of season, a good rule of thumb is to give your lawn an inch or two of water each week. It's best to apply a soaking watering early in the morning, between 3 and 4 am; you should avoid applying water during the hot, sunny portions of the day because of the threat of burning the grass.

6. When, and under what circumstances, should I fertilize my lawn?

It's best to wait until after spring.  You should work with OakLawn Landscaping to devise a soil sampling and fertilization plan to determine the base nutrient levels and necessary fertilization.  Excessive fertilization is not only a waste of money, but it also negatively affects the Chesapeake Bay by creating over-abundance of nutrients that promote vegetation growth and reduce fish and crab populations. 

7. When should I prune or trim my shrubs?

We'll look at your specific plant species to give you a definitive answer, but a good rule of thumb is to prune spring-flowering shrubs and trees shortly after they bloom.   On the other hand, summer-flowering shrubs and trees are best pruned a month or two before spring growth begins, because they bloom best on bloom best on new wood, and are best pruned 4-6 weeks before spring growth begins.
