LESCO 19-0-6 Dimension Pre-Emergent Fertilizer

When should I apply LESCO Dimension 19-0-6?

Apply in early spring before crabgrass germinates for the best prevention. Late-summer or early-fall applications can target certain winter annual weeds or help prevent early-spring crabgrass, but rates and timing differ by region and use program. Follow the label.

Can Dimension control crabgrass that has already sprouted?

Sometimes, but only very young crabgrass. Its limited early post-emergent activity works before crabgrass develops its first tiller (generally before the fifth leaf). It will not reliably control mature crabgrass.

How much area does one 50 lb bag cover?

At the existing 4 lb per 1,000 sq ft coverage-planning rate, one 50 lb bag covers about 12,500 sq ft. The actual required rate depends on region, grass mowing height, and whether use is pre-emergent or very early post-emergent. Always follow the label rate.

What weeds does it help prevent?

The label lists crabgrass and other susceptible annual weeds. Depending on timing and label program, these include annual bluegrass (Poa annua), goosegrass, foxtails, chickweed, henbit, spurge and others. Apply before their germination for pre-emergent control.

Does it feed the lawn as well as prevent weeds?

Yes. The 19-0-6 formula supplies nitrogen for lawn growth and green color plus potassium for overall turf health. The PolyPlus OPTI45 portion is designed for more gradual nitrogen feeding.

Is Dimension better if I applied a little late in spring?

Dimension offers a limited advantage over pre-emergents without early post-emergent activity: it can control very small, newly emerged crabgrass before tillering at the appropriate label program rate. Don't count on it once crabgrass is established.

Do I need to water Dimension in?

Irrigation or rainfall within a few days of application helps move the herbicide to the soil surface for activation. Water according to the product label and avoid runoff into drains or waterways.

How long should I wait before overseeding?

The label generally requires waiting 12 weeks after treatment before reseeding, overseeding or sprigging. A single fall application may permit perennial ryegrass overseeding after at least 8 weeks. Read the product label for all conditions.

Can I apply it to a newly seeded lawn?

Use only on well-established turf. The grass needs a good root system and at least two mowings after seeding, sodding or sprigging before application. Do not apply to sensitive or stressed turf contrary to label directions.

Which types of grass can I use it on?

The label lists many established cool- and warm-season grasses, including tall fescue, Kentucky bluegrass, perennial ryegrass, bermuda, zoysia and St. Augustine. Some fine fescues and creeping bentgrass varieties are sensitive, and colonial bentgrass is excluded. Check your grass type on the label.
