Sun Gold Tomato in Zone 7A — Pacific Northwest

Sun Gold Tomato is practically sunshine in fruit form, and its exceptional sweetness is even more pronounced with our cool PNW nights. These golden gems are fantastic eaten fresh off the vine, tossed in salads, or even roasted to intensify their flavor. Plus, the sheer volume of tomatoes you'll get from a single plant is incredibly satisfying in our relatively short growing season.

Our wet springs and mild summers can present challenges, but with some careful timing, Sun Golds thrive here. Our 183-day growing season gives you plenty of time to get a great harvest, as long as you get started early and provide consistent care.

Start your Sun Gold Tomato seeds indoors from mid-March through early April, about six weeks before you plan to transplant them outside. Use seed trays or small pots filled with seed-starting mix. Keep them warm – around 70-75°F – using a heat mat if needed, since our spring soil temps are often cool.

Provide plenty of light. An overcast spring day here won't cut it; you'll need a grow light to prevent leggy seedlings. Water gently from the bottom to avoid damping off. Place your tray in a shallow dish of water and let the soil soak it up.

Transplant your Sun Gold Tomato seedlings outdoors from early May through early June, once the danger of frost has passed. Before planting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade, increasing the time and sun exposure each day.

Plant them 24-36 inches apart in a sunny spot with well-drained soil. Be mindful of late cold snaps that can still occur during this time and protect them with row covers if needed.

Sun Gold Tomatoes are thirsty plants, and consistent watering is key, especially during our dry summer months. Aim to water deeply about 1-2 times per week, providing about 1-2 inches of water each time. Use the "finger test" – stick your finger into the soil about 2 inches deep. If it feels dry, it's time to water.

Water at the base of the plant to avoid wetting the foliage, which can encourage fungal diseases in our climate, even with relatively low humidity. Irregular watering is a major cause of fruit cracking, so be consistent.

Signs of underwatering include wilting leaves and blossom end rot (dark, sunken spots on the bottom of the fruit). Overwatering can lead to yellowing leaves and root rot. A good layer of mulch, like straw or wood chips, will help retain moisture and keep the soil temperature consistent.

Sun Gold Tomatoes are vigorous indeterminate growers, meaning they'll keep growing and producing all season long. They need strong support to keep them off the ground and prevent sprawling.

A tall, sturdy tomato cage is often the easiest option, but staking also works well. Install the support at planting time to avoid damaging the roots later. As the plant grows, gently weave the stems through the cage or tie them to the stake with soft twine.

Pruning is essential for managing Sun Gold Tomatoes, otherwise they will quickly take over your garden. Focus on removing suckers – the small shoots that grow in the "V" between the main stem and branches.

Pinch them off when they're small to redirect energy to fruit production. Also, remove the lower leaves that touch the soil to improve air circulation and reduce the risk of disease. As the first frost approaches in mid- October, top the plant to encourage the remaining green tomatoes to ripen.

You can expect your first Sun Gold Tomato harvest from late June through mid-August, about 57 days after transplanting. The tomatoes are ripe when they turn a vibrant orange-gold color and are slightly soft to the touch. They should practically fall off the vine when gently touched.

Harvest regularly to encourage continued production. Sun Golds are known for their intense sweetness, which develops best when they're fully ripe on the vine. If frost threatens before all your tomatoes are ripe, pick the green ones and bring them indoors to ripen in a paper bag.

Here are some common problems you might encounter with Sun Gold Tomatoes in the Pacific Northwest:

• Cracking
• What it looks like: Splits in the tomato skin, either concentric circles around the stem or radial lines radiating from the stem.
• What causes it: Inconsistent watering, especially heavy watering after a dry spell. The fruit absorbs water faster than the skin can expand.
• How to fix/prevent it: Water consistently to avoid the dry/wet cycle. Mulch well to maintain even soil moisture. Harvest promptly when ripe.
• Over-Production
• What it looks like: An overwhelming abundance of tomatoes, more than you can possibly eat or give away.
• What causes it: Sun Golds are just naturally prolific! Our mild summers and cool nights allow them to produce heavily.
• How to fix/prevent it: Embrace it! Find creative ways to use your tomatoes – sauces, salsas, roasting, freezing. Share with neighbors. Succession planting can help avoid a massive glut all at once.
• Early Blight
• What it looks like: Brown spots with concentric rings (target or bullseye pattern) on lower leaves first, spreading upward. Leaves yellow and drop.
• What causes it: Fungal disease (Alternaria solani) that thrives in warm, humid conditions. Spreads via soil splash onto lower leaves. While our summers are mild, overcast spring days can create enough humidity for blight to take hold.
• How to fix/prevent it: Remove and destroy affected leaves (don't compost). Mulch to prevent soil splash. Water at the base, not overhead. Improve air circulation through spacing and pruning. Copper fungicide can slow the spread. Rotate crops yearly.

Pacific Northwest Specific Challenges: While late blight is a concern for tomatoes in general, early blight is more common in our region. Cool soil in spring can slow growth and make plants more susceptible to disease. Our relatively short heat can limit fruit production if plants aren't started early enough. Slugs can also be a nuisance, especially in wet springs, so use slug bait or traps as needed.

Good companions for Sun Gold Tomatoes include basil, which is said to improve tomato flavor and deter pests. Carrots help loosen the soil, and parsley attracts beneficial insects. French marigolds deter nematodes and other soil pests.

Avoid planting tomatoes near brassicas (cabbage, broccoli, kale) as they can stunt tomato growth. Fennel inhibits the growth of many plants, including tomatoes. Corn can attract tomato hornworms.
