Getting your yard ready for spring
Southern Methodist University has one of the prettiest campuses in the
nation, especially when it is ablaze with colorful flowers and shrubs in the
spring. You, too, can have a beautiful yard this spring and summer by following
these tips from SMU's team of landscapers and horticulturists:
Irrigation
- If you don’t have an automatic irrigation system and you want one, this is the
best time of the year to get one. The mess in your yard covers the quickest in
the spring.
- Raise the irrigation heads in the yard so the top of the cap is even with the
soil or the thatch in your yard.
- Run your water system to make sure you have no broken pipes or broken heads. This
will help ensure you are getting water where it needs to be: on the yard and
plants – not the street.
- Change out the battery in your wireless rain/freeze shutoff. The rain/freeze
shutoff needs a new battery every 8 – 12 months.
Perennial/Color Beds
- Fertilize your roses with an organic, slow-release fertilizer and mulch with
compost. Prune roses as recommended by the
roses associations.
- Begin adding mulch to your other perennial and color beds. You should
incorporate an organic fertilizer and/or compost before adding the mulch.
- Divide large perennials.
- Cut back ornamental grassed to prevent thatch buildup.
- Cut back Liriope to remove dead or damaged foliage. This can be done with a
mower. Check irrigation head placement first to avoid mowing the heads off.
- Begin proper soil preparation for new summer color beds.
- You can apply a pre-emergent herbicide in your beds to reduce amount of weeds.
- Make an effort to use organic fertilizers and pesticides instead of synthetic
ones.
Turf Grasses
- The No. 1 thing to know is what type of turf grass you have in order to
know what you should do.
- Apply a pre-emergent herbicide for summer annual weeds. Check the label to make
sure you can use the chemical on your type of turf. Always read the product
label before using.
- Aerate your lawn to remediate soil compaction. Aeration is the process of
removing a large number of soil cores in order for the soil to spread out,
reducing compaction so the turf roots have more room to grow and better
air and water movements.
- The first application of fertilizer for warm-season grasses should be in May.
Use a fertilizer with a high nitrogen content and apply according to the label.
A slow-release nitrogen source is best.
- Mower maintenance: clean air filters, replace spark plug, check oil levels,
clean out mower deck and sharpen mower blades.
- Recommended mowing heights: St. Augustine grass is 2 inches every 5 to 7 days;
Bermuda grass is 1-inch every 3 to 4 days.
Trees
- Contact a Certified Arborist for any major tree work.
- Don’t top off crepe myrtles!
- Mulch around trees to prevent lawn mower and weed eater damage.
- If you want to do some work on your own, please follow industry
practices for the care of trees (www.treesaregood.com)
- Make sure the soil level is at the proper height for the base of the tree.
Trees should not look like a telephone pole in the ground.
- Eliminate other plantings at the base of the tree. Most of the tree’s roots are
in the top 2 feet of soil, so any tilling around the trees will damage the
roots.
