How to Start Your Own Backyard Garden
How to Start Your Own Backyard Garden
Whether you have a large yard or just a few pots on a balcony, you can grow food successfully in the Marianas with some planning and creativity.
1. Assess Your Space
Look for areas with at least six hours of sunlight a day and good drainage. If your soil is rocky or compacted, try raised beds or container gardening. Even recycled buckets or wooden pallets can become productive garden plots.
2. Plan Your Layout
Map out your planting area. Group crops with similar sunlight and water needs together. Rotate crops each season to avoid soil depletion and pest buildup. Intercropping is the process of planting multiple species in the same space. This process can improve yields and protect plants naturally.
3. Prepare the Soil
Healthy soil is the foundation of a successful garden. Mix compost or aged manure into your soil to boost nutrients and microbial life. If your soil is sandy or clay-heavy, adding organic matter improves structure and water retention.
4. Choose Your Plants Wisely
Select crops suited to the current season. Leafy greens and herbs often thrive during cooler months, while fruiting plants like tomatoes and cucumbers prefer warmth. MPA and NMC-CREES provide local planting calendars for Saipan, Rota, and Tinian.
5. Water Efficiently
Water in the early morning or late afternoon to reduce evaporation. Drip irrigation systems or simple soaker hoses help conserve water. Collect rainwater using barrels or gutter systems—an eco-friendly and cost-effective option.
6. Manage Pests Naturally
Avoid harsh chemicals that harm beneficial insects and contaminate soil. Instead, use neem oil, garlic spray, or chili pepper solutions as natural repellents. Encourage biodiversity by planting flowers that attract pollinators and predatory insects like ladybugs.
7. Harvest and Replant
Pick produce regularly to encourage continuous growth. After harvesting one crop, replant quickly to maintain soil cover and steady food production throughout the year.
A healthy garden feeds itself through a natural cycle of growth and decay. Composting transforms kitchen scraps and yard waste into nutrient-rich fertilizer.
Start simple:
Save vegetable peelings, fruit scraps, eggshells, and yard clippings
Avoid meat, dairy, or oily foods (these attract pests)
Alternate “green” materials (fresh waste) with “brown” materials (dry leaves, cardboard)
Popular methods in CNMI:
Compost heap: A pile turned periodically to aerate and decompose
Worm composting (vermicompost): Red worms break down organic matter quickly
Bokashi method: Uses beneficial microbes to ferment food waste (ideal for small spaces)
Composting reduces waste sent to Saipan’s landfill and cuts down on chemical fertilizer use. Many MPA workshops teach basic composting techniques and offer free compost starter kits.
The CNMI’s tropical climate allows for year-round gardening, though choosing the right crops is key. The islands’ warm temperatures, high humidity, and seasonal rains support a wide range of fruits, vegetables, and herbs.
Recommended crops include:
Leafy greens: kangkong (water spinach), amaranth, lettuce, sweet potato leaves, and spinach
Vegetables: tomatoes, eggplants, okra, cucumbers, long beans, bitter melon, and squash
Fruits: papaya, banana, pineapple, guava, and melons
Root crops: taro, cassava, yam, and sweet potato
Herbs and spices: lemongrass, ginger, turmeric, basil, and green onions.
Tip: Combine fast-yielding vegetables with longer-term perennials. For example, papaya can produce fruit within 6–8 months, while quick crops like kangkong or cucumbers can be harvested within 30–45 days.

Gardening in the islands isn’t without obstacles—limited space, pests, and changing weather can all pose difficulties. But each challenge has a solution:
Limited space? Try container gardening or vertical towers
Poor soil? Build raised beds and add compost regularly
Pests? Use netting, natural repellents, and crop rotation
Drought? Collect rainwater and mulch heavily to retain moisture
Strong winds? Use trellises and natural windbreaks with shrubs or banana plants
By adapting techniques to local conditions, anyone—from a family in Garapan to an apartment resident in Chalan Kanoa—can grow successfully.
