Timing Your Harvest: How to Know When Garden Crops Are Ready for Baby
March 5, 2026
Harvesting at the right time matters more when you are growing for a baby. Too early and the food lacks flavor. Too late and the texture is wrong for safe BLW eating. Here is how to tell when each crop is ready.
Root vegetables
Carrots
Pull when the tops are about finger-width at the soil line. Smaller carrots steam softer and have a sweeter flavor. Large, woody carrots need much longer cooking to reach baby-safe softness.
Beets
Harvest at golf-ball size. Larger beets develop tougher rings and need more roasting time. Small beets roast tender in 30-40 minutes and are easier to cut into BLW-sized pieces.
Sweet potatoes
Dig when the vines start to yellow, usually 90-120 days after planting. Medium-sized tubers mash the most smoothly. Cure at 85 degrees for 10 days to convert starches to sugars before feeding to baby.
Squash and zucchini
Zucchini
Pick at 4-6 inches long. At this size, the flesh steams evenly and the skin is tender enough that you do not need to peel. Large zucchini develop seeds and a spongy center that does not work as well for BLW.
Butternut squash
Ready when the skin is tan and hard. A fingernail should not dent the surface. Cure at room temperature for 2 weeks before cooking for sweetest flavor.
Leafy greens
Kale and spinach
Harvest younger, smaller leaves for babies. They steam softer and have a milder flavor than mature leaves. Pick outer leaves first so the plant keeps producing from the center.
Swiss chard
Strip the leaves from the stems. Leaves steam quickly; stems need much longer cooking. For babies, use the leaves only.
Fruiting crops
Tomatoes
Fully ripe tomatoes slip off the vine with a gentle tug. For babies, peel by scoring and blanching briefly, then remove seeds and serve as soft wedges.
Green beans
Pick when beans are bright green and snap cleanly when bent. If the seeds inside are visibly bulging, you have waited too long. Overmature beans are tough and stringy, which is harder for babies to eat safely.
The harvest window
Most crops have a window of 1-2 weeks when they are at peak quality. Check your garden every day or two during this period. SowAndSpoon sends harvest reminders 7 days before your expected harvest date so nothing slips past.
