A GUIDE TO GROWING HEMP IN DELAWARE

Are you growing hemp in Delaware? Far more farmers are looking into it given recent relaxations of laws and permits for growing this particular crop, especially as demand for it grows commercially. Delaware is such a small state that it’s not thought of as a breadbasket state, and yet its population is equally small, mostly concentrated around the capital city of Wilmington. That leaves a lot of land free for agriculture. Keep reading to learn 9 different factors that might influence your success in growing hemp or Delaware or not.

Plant Hardiness Zone(s)

Plant Hardiness Zones: Given its small size, Delaware only has two plant hardiness zones, unlike many other states that have more. Northern Delaware sits in zone 6, while southern Delaware is zone 7, although the coastal area of Sussex is more specifically 7B.

Thermal Profile

Thermal Zones: Delaware’s climate is temperate and humid. Hemp thrives in temperate climates, making it easier to grow here. The average daily temperature for the year is 54F, ranging from summer highs of 86F to winter lows of 23F.

Length of Growing Season

Growing Season Length: The average growing season here is 173 days long, which is far longer than the four months Hemp typically needs for maturity to good cultivation. The frost-free season typically starts 4/25 and lasts until 10/15.

Average Sunlight Throughout Growing Season

Average Annual Precipitation

Delaware averages 45 inches of average precipitation. The rainiest month is July at 5.4 inches on its own, which helps for a thirsty crop like hemp.

Surface Elevation

The mean elevation of the state is the lowest of all the states, at just 60 feet. The lowest point is the Atlantic coastline, and the highest elevation is still less than 500 feet over sea level.’

Average Sunlight Throughout Growing Season

Average Annual Sunlight: Delaware typically gets 2500 hours of annual sunlight. Most of this occurs on 201 sunny days, although half of them are partly cloudy.

Soil PH

As part of the mid-Atlantic region, the soil tends towards a pH that is slightly acidic. Regular applications of lime might be necessary for planting. Urban areas might have weathered building materials that contribute to the higher pH. Elemental sulfur can help loosen iron content in the soil.

Soil Composition

Delaware has two different growing areas. The Piedmont is only in the northern corner, covering 5 percent of the state with rolling hills; slopes are stony, but the valley soils are loamy and rich. The rest of the state is coastal plain with sandy soil that is well-drained.

Notable Pests

Possible pests for Delaware crops of all kinds include many familiar names, including snails, slugs, grubs, rabbits, groundhogs, and moles. Insects and bugs to watch out for include beetles, aphids, caterpillars, and ants. One invasive species getting a lot of attention is that of the spotted lanternfly.
