Why Spring Gardening Is Worth It

Gardening in spring is good for your body and your mind. Research has shown that spending time working in a garden can lower stress levels, lift your mood, and even improve focus. And if you're growing vegetables or herbs, you can cut grocery costs while eating fresher food than anything you'll find at a store.

National Gardening Month, celebrated every April since 1981, is a great reminder that growing something — anything — is one of the most rewarding things a person can do. In Tualatin, spring gardening is also a way to enjoy and improve your outdoor space while connecting with your neighbors and community.

What to Plant in April for Spring Gardens in Tualatin

A common question for beginners is: "What vegetables grow well in spring?" In the Tualatin area, April is a great window for cool-weather crops. Here are some top picks:

• Lettuce — Fast-growing and loves cool temps. Great for salads straight from the yard.
• Spinach — Thrives in containers or beds. Ready to harvest in about six weeks.
• Peas — Direct sow in the ground. They handle light frost and climb on trellises.
• Kale — Tough and nutritious. One of the most beginner-friendly spring vegetables.
• Radishes — Ready in just three to four weeks. Perfect for impatient gardeners and kids.
• Pansies & Violas — Colorful spring flowers that love April's cooler temperatures.

If you're wondering how to start a spring garden at home with tomatoes or peppers, start those indoors now under grow lights. They need warmer soil — usually above 60°F — before going outside. Check local frost date guidelines for Tualatin to time your transplants correctly.

PRO TIP:  One of the best spring gardening investments Tualatin residents can make is building a simple compost bin. Kitchen scraps, yard clippings, and fallen leaves break down into rich, free fertilizer over time. Start one this April, and you'll have fantastic compost ready to use by next season.

Preparing Your Soil and Garden Beds

Great soil is the foundation of every great garden. Before you plant, take these four steps to get your beds ready:

1. Clear out weeds and dead plant material left over from last season. Weeds steal water and nutrients from your plants.
2. Loosen the soil to a depth of 10–12 inches using a garden fork or trowel. This helps roots spread and water drain properly.
3. Add compost or aged manure. Mix in 2–3 inches to improve soil texture and add natural nutrients. Garden centers in Tualatin carry bagged and bulk compost options.
4. Check your soil pH. Most vegetables prefer a pH between 6.0 and 7.0. An inexpensive test kit from any garden center will tell you where you stand.

Beginner-Friendly Gardening Tips for April

Start small.  A 4x4 raised bed or a few large containers is plenty for a beginner. It's much easier to manage a small garden successfully than to struggle with a large one.

Water wisely.  Most spring vegetables need about one inch of water per week. Check the soil with your finger — if the top inch is dry, it's time to water.

Label your plants.  Popsicle sticks, garden markers, or even pieces of tape on rocks work great. It's easy to forget what you planted where.

Shop local garden centers in Tualatin.  Local nursery staff know your area's climate and can point you toward varieties that perform best in your conditions. Shopping local also means your plants are already adapted to OR weather.

Be patient.  Seeds germinate at different rates. Don't dig them up after two days. Give them time, keep them moist, and most will surprise you.
