In light of those very garden-friendly parameters, here is a month-by-month guide that will carry you through an entire year of planting a zone 9 vegetable garden. Planting season extends all the way to the end of the year if the days are mostly sunny. The growing season in zone 9 typically lasts from late February to early December. Read on for tips on planting a zone 9 vegetable garden. Space transplants in the vegetable garden 18 inches (46 cm.) from each other and in rows that are 36 inches (91 cm.) apart. Eggplant transplants can go out in the garden once temperatures stay reliably above 50 degrees F. Thin seedlings so they are 2 to 3 inches (5 to 7.6 cm.) apart. However, because the growing season is longer than most areas of the country and you can plant nearly year-round, establishing a zone 9 planting guide for your climate is essential. Start seeds in soil of an inch (0.6 cm.) deep. Plant viruses are incurable so be sure to remove infected plants immediately and destroy them to prevent further spread.The weather is mild in USDA plant hardiness zone 9, and gardeners can grow nearly any delicious vegetable without worry of hard winter freezes. Many plant viruses are transmitted by pest insects as they feed, or from plant-to-plant contact via dirty tools. Crop rotation is effective chemical-free prevention.Įggplant viruses may cause yellow circles, spots, or other irregular patterns on eggplant leaves. These fungal diseases are difficult or impossible to treat, but copper fungicides and chlorothalonil are labeled for pretreatment for early blight. Eventually, the yellowing will spread across the entire plant as it dies from an inability to transport nutrients to its tissues. Both diseases come on suddenly, sometimes only affecting part of the plant at first. If the soil pH is too high or low, your plant won’t be able to utilize the nitrogen in the soil, no matter how much you apply, so make sure to test soil pH along with nutrient levels.Įarly blight and Verticillium wilt are caused by fungal pathogens that are common in the soil. A dose of balanced fertilizer, like a 10-10-10, will quickly remedy this situation. Apply 2 to 4 inches (5-8 cm.) of organic mulch and water these plants more frequently, preferably in the morning.Įggplants that develop overall yellowing may need nitrogen - a soil test will quickly reveal if this is the situation. Plants that aren’t getting enough water may initially wilt during midday, yellowing as the water stress increases. Yellowing of leaves is often caused by care problems like irregular watering or a lack of nitrogen in the soil. Both of these pests can be controlled with a premixed insecticidal soap, applied once a week until all signs of the pests are gone. As the insect populations increase, these damaged leaves may drop or dry up, leading to sunburn on fruits. Spider mites and lace bugs can cause yellowing when they feed on plant leaves. Eggplant with Yellow LeavesĮggplant turning yellow may be indicative of more serious problems if the yellowing is on leaves. This damage may appear as cream to tan spots, or might cover the entire exposed surface of the fruit. If this color is appearing on your larger eggplants, but sparing the smaller ones, try harvesting the fruits earlier.Īnother common cause of yellowing of eggplants is sunburn, which happens when leaves are damaged or removed, exposing the skin of tender, young fruits to excessive ultraviolet radiation. Light colored eggplants are prone to yellowing when they’re approaching an over-ripe state. If you’ve never grown a specific variety before, yellow could simply be the color of the fruit on your plant. Eggplant fruits can range in color from pale green to a deep purple that looks black, including many that appear in shades of yellow, or even white. Although many eggplants are purple, not every variety produces this iconic fruit color. Most people think of large, waxy, purple fruits when eggplant comes to mind. If these plants start to show signs of trouble, like yellow fruit or leaves, knowing how to fix yellow eggplant will keep your harvest on track. Eggplants are certainly not for every gardener, but to those brave souls who love them, the appearance of tiny fruits on young plants is one of the most anticipated moments of early summer.
