Greenhouse Growing

In Maryland, utilizing a greenhouse can significantly enhance cantaloupe production. It protects plants from unexpected cold weather and pests, while allowing growers to maintain a controlled environment for optimal growth throughout the year. Greenhouses also extend the growing season, allowing for earlier planting in spring and later harvesting in fall.

Consider investing in a 10×12 FT Greenhouse priced at $1,199 to ensure your cantaloupes thrive in a controlled environment.

Starting Indoors

In Maryland (Zone 7a), begin seeds indoors between March 15 and April 15. This timeline ensures healthy seedlings ready for outdoor transplantation starting from late April to early May once the risk of frost has passed.

Transplanting Seedlings

Transplant seedlings outdoors from May 1 to May 15, ensuring the soil has warmed above 60°F consistently. Space the seedlings 12-24 inches apart in rows with at least 36 inches between rows for optimal growth.

General Care and Maintenance

Watering

  • Provide consistent and deep watering to maintain evenly moist soil. Maryland’s humid climate may require frequent watering during dry spells to prevent soil dryness.
  • Water at the base of plants to avoid leaf wetness, reducing the risk of fungal diseases.

Fertilizing

  • Apply a balanced fertilizer during planting and when the first fruits start forming. Incorporating compost before planting can enhance soil fertility and structure.

Pest and Disease Management

  • Regularly monitor for common pests like aphids, cucumber beetles, and powdery mildew. Maryland’s temperate climate can lead to increased pest activity.
  • Implement organic or integrated pest management methods to protect cucumber plants from pests and diseases.

Harvesting

  • Harvest cucumbers when they reach the desired size and color. Regular harvesting promotes continuous fruiting and prevents over-mature fruits.

Cantaloupe Facts

Cantaloupes are a type of muskmelon that are known for their sweet, juicy flesh and distinct netted skin. They are often enjoyed fresh, in salads, or as a refreshing treat on a hot day.


In my garden, I try to compost as much as possible, so I can mix in the nutrient-rich compost into my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”.
If you don’t have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.

If you are uncertain of the quality of your soil, you can get easy-to-use soil tests at Amazon for 17 dollars. Check latest prices here: Soil testing kit.

Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan your crops according to your climate you will succeed with any plant you want.

The satisfaction when you harvest your own produce is well worth the time you put in 🙂
