Why Texas Is Different (Hill Country, Central Texas, and Beyond)
Texas is large enough to span several USDA hardiness zones, and growing conditions vary quite a bit between regions. The Texas Hill Country — including areas like Kerr, Gillespie, and Bandera counties — generally falls in zones 8a and 8b, with mild, short winters, hot summers, and often thin, rocky, alkaline soil over limestone or caliche. Central Texas more broadly shares much of that warmth, though soil and rainfall vary by county. Because of the state’s size, treat any planting date in this guide as a general range to check against your own zone, soil, and local extension office rather than a fixed date. See this site’s guide to finding your zone and planning around it if you’re not sure where you fall.
Growing Tomatoes in Texas
When to plant
In much of Texas, tomatoes are typically set out as transplants in early-to-mid spring, once nighttime temperatures have warmed and the danger of frost has passed, with a second round sometimes planted in mid-to-late summer for a fall crop in warmer zones. Exact timing shifts by several weeks depending on where in the state you are, so it’s worth checking local frost-date guidance rather than relying on a single statewide month.
What should never be planted near tomatoes?
Tomatoes are generally considered poor neighbors for other nightshades like potatoes (shared pest and disease pressure, including blight), as well as for brassicas like cabbage and broccoli, which tend to compete for similar nutrients and can stunt tomato growth. Fennel is also commonly flagged as a plant to keep away from tomatoes, since it’s thought to inhibit nearby growth.
Common mistakes
Common tomato-growing mistakes include planting too early (before soil and night temperatures are reliably warm), spacing plants too closely (which limits airflow and raises disease risk), overwatering or watering inconsistently (which can cause blossom-end rot and cracking), skipping support structures like cages or stakes until plants are already sprawling, over-fertilizing with high-nitrogen formulas (which favors leafy growth over fruit), letting weeds compete for water and nutrients, ignoring early signs of pests or disease, pruning too aggressively or not at all, and harvesting too early or too late for the variety.
Growing tomatoes in a 5-gallon bucket
A single 5-gallon bucket is generally considered enough space for one tomato plant, ideally a compact or determinate variety bred for containers rather than a large indeterminate vining type. Drainage holes and consistent watering matter more in a bucket than in the ground, since container soil dries out faster, especially in Texas summer heat.
Planting Kale in Texas
Space and growing conditions
Kale generally needs around 12-18 inches between plants to have enough room to mature, and it prefers full sun to partial shade with consistently moist, well-drained soil. In Texas, kale tends to perform best as a cool-season crop — fall through winter and into early spring in most of the state — since it’s a cold-hardy brassica that generally handles light frost well but struggles and turns bitter in sustained summer heat. Hardiness varies by cultivar, but many kale varieties can tolerate temperatures down into the high teens Fahrenheit, with some cold-tolerant types reportedly surviving well below that; treat these as general ranges rather than guarantees, since local conditions and plant maturity both matter.
Kale vs. ornamental kale
Edible kale and ornamental (flowering) kale are closely related brassicas and can look similar, especially when young, but they’re typically bred for different purposes. Edible kale varieties are selected for flavor and leaf texture for eating, while ornamental kale is bred mainly for colorful, ruffled foliage used in fall landscaping and containers. Ornamental kale is generally considered edible in a technical sense but tends to taste more bitter and tougher than culinary varieties, so it’s usually grown for looks rather than for the table.
Does kale grow back after cutting?
Yes, generally — kale is a biennial that typically regrows new leaves from the center of the plant after an outer-leaf harvest, as long as you leave the growing point intact. Harvesting outer leaves gradually, rather than cutting the whole plant at once, tends to extend the harvest window considerably.
Planting Onions in Central Texas
When to plant
Onions in central Texas are commonly planted from sets or transplants in winter to early spring, since onions are cool-season crops that form bulbs based partly on day length, and central Texas’s mild winters generally allow an earlier start than colder parts of the state. Exact timing is best confirmed locally, since it shifts with both variety (short-day onions are generally favored in southern Texas) and winter severity in a given year.
Common onion mistakes
Frequent onion-growing mistakes include planting the wrong day-length type for the latitude (long-day onions generally underperform in southern Texas), planting too deep (onions generally prefer shallow planting, with the top of the bulb near the soil surface), crowding plants too closely, letting weeds compete for nutrients, inconsistent watering during bulb formation, and harvesting before the tops have naturally begun to fall over and dry.
What cannot be planted near onions?
Onions are generally considered poor companions for beans and peas, since alliums can inhibit the growth of legumes, and for asparagus in some gardeners’ experience. They’re commonly planted near carrots, lettuce, and brassicas without major issues, though results can vary by garden.
Note that growing onions from seed rather than sets or transplants generally takes longer to reach a mature bulb within a single season — it does not require two full years, but seed-grown onions typically need an earlier start indoors to catch up to the timeline of sets.
Vegetable Gardening in the Texas Hill Country
Soil and climate basics
Hill Country gardens commonly deal with thin topsoil over limestone or caliche, alkaline soil pH, average rainfall around 30 inches a year that can arrive unevenly (long dry spells followed by heavy downpours), and significant deer pressure. Raised beds filled with amended soil are a common workaround for the rocky, shallow native soil, and native or well-adapted plant varieties tend to need less supplemental water and fare better against deer and local pests.
What grows well, by season
In summer heat, crops like okra, mustard greens, collard greens, and pumpkins are generally considered more heat-tolerant choices. Fall and early winter favor cool-season crops like lettuce, spinach, and radishes, while winter into early spring suits carrots and asparagus. Warm-season crops such as eggplant, peppers, beans, corn, and potatoes are typically planted as temperatures climb in spring, once nights are reliably warm.
Can You Garden Year-Round in Texas?
In much of Texas, including the Hill Country, mild winters generally make year-round vegetable gardening feasible, since there’s rarely an extended hard freeze that shuts down growing entirely. That said, “year-round” usually means rotating between different crops each season — cool-season vegetables in fall through early spring, heat-tolerant and warm-season crops in late spring through summer — rather than growing the same vegetables continuously. For a month-by-month breakdown of that fall transition specifically, see this fall planting guide, which includes a Texas-specific timeline.
FAQ
What is the 70/30 rule in gardening? This isn’t a single standardized term across gardening references, and different sources use it to mean different things — most commonly, allocating roughly 70% of garden space to reliable, known-productive crops and 30% to new varieties or experiments. Treat it as a loose planning heuristic rather than a fixed rule.
What is the “5, 4, 3, 2:1” gardening method? This also isn’t a widely standardized term in mainstream horticultural references. It most likely refers to a spacing or succession-planting ratio used informally by some gardeners, but because there’s no consistent definition across sources, it’s safer to rely on the spacing and timing guidance given on your seed packet or from a local extension office than to assume a specific meaning here.
What are the best vegetables to plant right now in Texas? That depends heavily on the season and your part of the state: cool-season crops like greens, carrots, and onions in fall through winter, and warm-season crops like tomatoes, peppers, and beans once nights are reliably warm in spring. Check a local planting calendar for your specific zone for the most accurate answer.
