Fall and winter gardening deals to buy before Amazon Prime Day

Most people think gardening is a spring fling: seed packets and flowers sprouting and veggies growing galore. But any experienced grower knows the truth: fall and winter are where the real strategy and technical work happen. This is when you build the foundation for next year’s bounty, protect your soil from the elements (which is a bigger deal than many of us give credit), and sneak in a few cool-season crops while everyone else is hanging holiday lights.

And the timing couldn’t be better. Ahead of Prime Big Deal Days (officially happening October 7–8), Amazon has provided us with a bounty of early deals on cool-season gardening essentials.

Once the temperatures start shifting, gardeners in every hardiness zone are stocking up on the tools, grow lights, and frost covers that carry your plants from one season to the next. Think of it as an off-season training camp for your tomatoes, squash, and roses — one that could make the difference between limp spring seedlings and a garden that thrives.

Why start your garden now?

Fall and winter prep depends heavily on your USDA hardiness zone. In colder areas (zones 3–6), gardeners are already racing the frost clock, buttoning up their raised beds with mulch, row covers, and garlic plantings before the soil locks up.

Zones 7–8 can squeeze in a bit more: overwintering onions, spinach, and brassicas while laying down compost to recharge soil biology. Here in Zone 9, where I garden, the growing season is long enough that cool-weather crops like kale, lettuce, and carrots can carry through winter, while citrus trees, ornamentals, and perennials benefit from thoughtful pruning and mulching before a potential cold snap.

Get to know your hardiness zone. Then, run through this checklist to get your basic idea of what you’ll need from now through the next few months:

Start now (fall):

• Plant garlic, shallots, and onions
• Sow hardy greens like kale, spinach, and arugula
• Mulch garden beds to insulate soil and suppress weeds

Over winter:

• Protect tender perennials with frost blankets
• Set up grow lights for indoor seed starting
• Water deeply before a hard freeze to protect roots

Prep for spring:

• Clean and oil garden tools
• Test soil pH and amend with compost
• Start tomatoes, peppers, and herbs indoors under grow lights

Grow lights aren’t just for urban gardeners; they’re essential for starting seeds in every zone. This 6-head setup provides full-spectrum light to mimic sunlight, ensuring seedlings develop strong roots and stems even when days are short. Zone 9a gardeners can get a head start on spring crops like tomatoes and peppers without relying on fickle winter sun.

Frost blankets like these act like cozy duvets for your bigger plants (go for floating row covers for vegetable garden beds). They trap warmth while still allowing airflow and moisture, protecting tender herbs and leafy greens from unexpected freezes. For me in 9a, where the occasional freeze can zap citrus or peppers overnight, a set of covers can mean the difference between survival and heartbreak.

Raised beds extend your season by warming up faster in spring and draining better in wet winters. Metal or cedar options available on Amazon hold up against weather and pests. In warmer zones, raised beds also let you rotate crops more easily without exhausting native soil.

Instead of buying bags of compost year after year, you can make your own nutrient-rich “black gold” right in the backyard. This compost bin speeds up decomposition with a dual-chamber design that lets you add fresh material while finished compost cures in the other side. By spring, you’ll have an endless supply of homemade compost to top-dress beds, amend soil, and feed seedlings.

Even in winter, soil can dry out, especially in windy or sunny climates. A drip kit like this one (which I personally use) ensures consistent moisture year-round at the base of your plants’ roots, reducing the risks of overwatering, plant stress, and diseases like blossom-end rot. These modular kits come in many size variations and can be customized to fit raised beds, containers, or orchards. It may look complicated, even intimidating, but it’s surprisingly simple, quick, and…fun? Personally, I loved setting mine up, and it’s been the best investment I’ve made for my garden to date.

Your soil’s pH and nutrient profile determine everything, from the sweetness of your tomatoes to the growth of, well, everything. While I always recommend you get an initial soil test done by your local extension office’s lab, you’ve got to have a reliable kit on hand that’ll give you the data you need to understand where you’re soil’s at after a whole season of adding amendments (or simply allowing your plants to take what they need from it). Yours may benefit from added lime, sulfur, blood meal, or other organic amendments this fall. Knowing your soil’s baseline now will save you major spring headaches.

---

Even a small pop-up greenhouse can extend your season by months, or even keep you growing year-round. These structures protect seedlings, herbs, and overwintering crops from frost while creating a humid microclimate. Warmer zone gardeners can still use them to overwinter peppers or keep their tender salad greens going well into January.

---

Fall is pruning season for fruit trees, roses, many perennials, and woody herbs. A sharp, ergonomic pair of shears like these ensures clean cuts that heal quickly, preventing disease entry. Don’t forget some alcohol wipes for added sanitation between plants — the last thing you need is an accidental disease spread, weakening your yield by spring.

---

Planning for spring means seed hoarding now. A waterproof seed storage and organization system like this one keeps packets labeled and viable for seasons ahead. When you’re juggling dozens of varieties (tomatoes, melons, beans, flowers), organization is the only way to avoid re-buying what you already own.

---

Warm soil equals faster, stronger germination. This 4-pack of seedling heat mats ensures even warmth across trays, which is especially critical for heat-loving crops like peppers, eggplants, and tomatoes — all of which are recommended to be started indoors 6-8 weeks before they’re planted in most zones. In cooler zones, heat maps extend the indoor seed-starting season.
