I have to chuckle when I hear you zone 9-10 gardeners talking about your “spring” gardens in April. Let’s be honest – you’ve been at this for months already, haven’t you? While the rest of us were still shoveling snow, you were harvesting tomatoes and tending to your winter crops. April for you isn’t so much a beginning as it is a pivot point, a time to shift gears as summer starts flexing its muscles.

Your April temperatures tell the story – days already reaching for 70-90°F, nights staying cozy at 50-60°F. Frost? That’s something you read about in gardening magazines. (Just kidding – RIP to so many orange trees these past few winters!) Your soil is warm and welcoming, practically begging for those heat-loving summer crops. And while I’m just starting to dream about my first tomato harvest, you’re probably already planning your second or third succession planting.

But I know it’s not all garden paradise. April marks the beginning of your strategic planning season. Those climbing temperatures mean you’re starting to think about shade cloth and irrigation systems. You’re watching your lettuce beds with a careful eye, knowing they’ll bolt at the first real heat wave. It’s a delicate dance of harvesting the last cool-season crops while preparing for the intensity of summer.

You’ve got the enviable position of being able to garden nearly year-round, but that comes with its own challenges. April is when you start playing defense against the summer sun. I imagine you’re out there in the early morning hours, getting your garden work done before the heat sets in, planning your watering schedules, and perhaps even setting up shade protection for your more delicate plants.

So while I’m celebrating my first pea shoots, you’re already thinking three seasons ahead. That’s the thing about gardening in zones 9-10 – you’re always looking forward, always planning for the next season, even as you’re tending to the current one. It’s a different rhythm from what most of us experience, but it’s got its own special charm.

Now, let’s talk about what’s on your April agenda – because while some of us are just getting started, you’ve got a full plate of transitions to manage…

Warm-Season Vegetables

Beans
These thrive in your warm April soil – perfect time for bush and pole varieties that can handle the heat.

• Best Varieties: ‘Yardlong’ (heat-tolerant Asian type), ‘Kentucky Wonder’ (reliable pole bean), ‘Dragon Tongue’ (heat-resistant bush bean), ‘Alabama Black’ (drought-tolerant heirloom).

Southern Peas
More heat-tolerant than regular garden peas, these legumes love your warm soil and will produce abundantly in summer heat.

• Best Varieties: ‘California Blackeye’ (reliable producer), ‘Zipper Cream’ (excellent flavor), ‘Mississippi Silver’ (heat-tolerant), ‘Purple Hull’ (drought-resistant).

Okra
A star performer who actually enjoys your climbing temperatures, okra will thrive in the heat and provide continuous harvests through summer.

• Best Varieties: ‘Charleston Gray’ (heat-tolerant watermelon), ‘Ambrosia’ (disease-resistant cantaloupe), ‘Thai Golden’ (tropical sweet melon), ‘Sugar Baby’ (compact watermelon perfect for small spaces).

Sweet Potatoes
April is ideal for getting sweet potato slips in the ground, giving them plenty of time to develop substantial tubers before fall.

• Best Varieties: ‘Beauregard’ (reliable and heat-tolerant), ‘Georgia Jet’ (quick maturing), ‘Centennial’ (excellent storage variety), ‘White Yam’ (tropical variety that loves heat).

Malabar Spinach
Not true spinach but a heat-loving vine that provides spinach-like greens all summer, perfect for trellising.

• Best Varieties: ‘Red Stem’ (beautiful purple stems), ‘Green Stem’ (vigorous climber) – both are excellent climbers that thrive in heat.

Tropical and Heat-Loving Specialties

Luffa Gourds
Plant now for both edible young gourds and mature sponges – these vigorous vines love the heat and humidity.

• Best Varieties: ‘Smooth Luffa’ (traditional sponge gourd), ‘Ridge Luffa’ (extra-long fruits) – both perform well in high heat.

Chayote
A perennial squash that’s perfect for your climate, producing tender fruits well into fall. Plant the whole fruit at an angle with the narrow end exposed.

Pigeon Peas
A perennial legume that serves as both food crop and beneficial companion plant, perfect for improving soil and providing summer shade.

• Best Varieties: ‘Hawaiian’ (compact growth), ‘Caqui’ (prolific producer) – both well-adapted to tropical conditions.

Heat-Tolerant Herbs
April is perfect for establishing herbs that can handle the summer heat.

• Best Varieties: Mexican Tarragon (more heat-tolerant than French tarragon), Cuban Oregano (succulent herb that thrives in heat), Lemongrass (perfect time to plant for summer growth), Thai Basil (more heat-resistant than Italian varieties).

Transplanting in April

If you have these started already, get them in the ground before peak heat:

Tomatoes
If you’re transplanting tomatoes in April, choose only ultra-heat-tolerant varieties and provide afternoon shade and deep mulch for summer survival.

• Best Varieties: ‘Solar Fire’ (bred for heat), ‘Florida 91’ (disease resistant), ‘Phoenix’ (crack resistant), ‘Heat Wave II’ (reliable producer).

Eggplant
These heat-loving vegetables will thrive in your warm soil. Plant deep and mulch well for best results.

• Best Varieties: ‘Florida Market’ (classic oval), ‘Long Purple’ (Asian type), ‘Thai Purple’ (prolific producer) – all heat-tolerant.

Peppers
Both sweet and hot peppers can be transplanted now. Consider shade cloth for afternoon protection.

• Best Varieties: ‘Coral Bell’ (sweet, reliable), ‘Caribbean Red’ (fiery hot), ‘Aji Dulce’ (sweet habanero-type).

April Garden Tasks for Zones 9-10

Soil Protection & Water Management

• Apply a thick layer of light-colored mulch around plants to reflect heat and retain moisture
• Set up shade cloth or screening (30-40% shade) over lettuce and other bolt-prone crops
• Install drip irrigation or soaker hoses before the soil gets too hot to work
• Check and repair any irrigation systems – you’ll be depending on them soon
• Consider adding ollas (buried clay pots) for deep watering of new plantings

Heat Management

• Create afternoon shade for tender transplants using shade cloth, row covers, or natural screening
• Plant tall crops like corn or sunflowers on the west side to shade more delicate plants
• Harvest remaining cool-season crops (lettuce, peas, etc.) before they bolt
• Move container gardens to areas that get afternoon shade
• Start shifting garden work to early morning or evening hours

Pest & Disease Prevention

• Monitor for early signs of spider mites (they love hot, dry conditions)
• Watch for whitefly and aphid populations – they can explode in warm weather
• Check for signs of bacterial wilt (common in warm, humid conditions)
• Remove any diseased plants promptly to prevent spread in warm conditions
• Consider companion planting with pest-repelling herbs like marigolds and basil

Garden Maintenance

• Start aggressive pruning of indeterminate tomatoes to prepare for heat stress
• Remove any remaining winter crops that are past their prime
• Thin fruit on citrus and deciduous fruit trees to prevent branch breakage
• Begin regular deep watering schedules for fruit trees
• Add extra support to climbing vegetables – winds often increase in spring

Planning Ahead

• Start planning your summer shade patterns
• Consider which beds will need to lie fallow during peak heat
• Begin preparations for hurricane/storm season
• Map out locations for heat-loving tropical perennials
• Plan succession planting schedules for beans and other quick crops

Fertilizing & Soil Health

• Apply balanced, slow-release organic fertilizers before peak heat hits
• Top-dress beds with compost to help retain moisture
• Add minerals like rock dust or kelp meal to boost plant resilience
• Consider foliar feeding in early morning to boost plant strength
• Monitor soil pH – it can change more quickly in warm conditions
