Have you ever looked at your kitchen scraps and thought, “Is there a way to use this instead of throwing it away?”

The answer is a resounding yes. Growing your own food from leftovers is not only a sustainable practice but also a deeply rewarding one. It’s a way to reduce waste, save money, and connect with nature—all while cultivating fresh, organic produce right in your home or garden.

Whether you have a sprawling backyard or just a sunny windowsill, you can turn everyday kitchen scraps into thriving plants. Let’s explore how to grow some of the most versatile and nutrient-packed foods from the leftovers you usually toss, and discover how this simple habit can transform your relationship with food and sustainability.

Peas (Sprouts)
Peas are a fantastic crop to regrow, especially if you’re looking for quick results. To grow pea sprouts from leftovers, simply save a handful of dried peas or the seeds from fresh pods. Soak them overnight in water, then plant them in a shallow container filled with soil.

Place the container in a sunny spot and water it lightly each day. Within a week, you’ll see vibrant pea sprouts emerging. These sprouts are packed with nutrients and add a fresh, crunchy texture to salads, sandwiches, and stir-fries.

Spring Onions
Spring onions are one of the easiest vegetables to regrow from leftovers. Instead of discarding the root ends, place them in a glass of water with the roots submerged and the green tops exposed. Keep the glass on a sunny windowsill, and within days, you’ll notice new green shoots growing.

Once the shoots are about 2-3 inches tall, you can transfer the onions to soil for continuous growth. Harvest them as needed by snipping the greens, and they’ll keep regenerating for weeks.

Coriander Stems
Coriander (cilantro) is a versatile herb that’s easy to regrow from stems. Save the lower part of the stems with a few leaves attached and place them in a glass of water. Change the water every two days to keep it fresh.

After about a week, you’ll see roots forming at the base of the stems. Once the roots are about an inch long, plant the stems in a pot with soil. Keep the pot in a sunny spot and water regularly. Soon, you’ll have fresh coriander leaves to garnish your dishes.

Broccoli Stems
Broccoli stems are often discarded, but they can be regrown into leafy greens. Save the bottom portion of the stem and plant it in moist soil with the cut side facing up. Keep the soil consistently moist and place the pot in a sunny location.

In a few weeks, you’ll notice small leaves sprouting from the stem. These leaves are edible and packed with nutrients, making them a great addition to salads, sautés, and soups.

Lettuce Heads
Lettuce is another easy vegetable to regrow from scraps. Save the base of a lettuce head and place it in a shallow bowl of water with the cut side facing up. Change the water every couple of days to keep it fresh.

Within a week, you’ll see new leaves sprouting from the center. Once the roots have developed, transfer the lettuce to soil for continuous growth. Harvest the leaves as needed, and enjoy fresh, homegrown lettuce in your salads.

Pumpkin Seeds
Pumpkin seeds aren’t just a tasty snack—they can also be planted to grow your own pumpkins. Save the seeds from a fresh pumpkin, rinse off any pulp, and let them dry for a few days.

Plant the seeds in nutrient-rich soil in a sunny spot, either in your garden or a large pot. Water them regularly and watch as they grow into sprawling vines that produce vibrant pumpkins. This is a wonderful way to turn your fall decorations into a sustainable gardening project.

Chard Leaves
Chard is a nutrient-dense leafy green that’s easy to regrow. Save the lower part of the stems and place them in a shallow bowl of water. Change the water every two days to keep it fresh.

Once you see roots forming, plant the stems in soil and keep them in a sunny spot. With regular watering, you’ll soon have fresh chard leaves ready to harvest. These greens are perfect for sautéing, adding to soups, or blending into smoothies.

Lemons (Seeds)
Growing a lemon tree from seeds requires a bit more patience, but the rewards are well worth it. Save the seeds from a fresh lemon, rinse off any pulp, and plant them in a small pot with well-draining soil.

Place the pot in a sunny location and water it lightly but consistently. While it may take several years for the tree to bear fruit, the fragrant leaves and blossoms will brighten your home or garden in the meantime.

Cucumbers (Seeds)
Cucumber seeds are another easy way to start your own vegetable garden. Save the seeds from a fresh cucumber, rinse them thoroughly, and let them dry for a few days.

Plant the seeds in nutrient-rich soil and place them in a sunny spot. Water regularly and watch as the vines grow, producing fresh cucumbers for your salads and snacks. Trellising the vines can help save space and make harvesting easier.

Mustard Greens
Mustard greens are fast-growing and perfect for regrowing from scraps. Save the base of the greens and place it in a shallow bowl of water. Change the water every two days to keep it fresh.

Once roots begin to develop, transfer the base to soil and keep it in a sunny location. Water regularly, and within weeks, you’ll have fresh mustard greens to add to your meals.
