How To Plant and Grow Sunflowers

Q: How long does it take for sunflowers to bloom?

It depends on the sunflower varieties you choose. When you’re growing sunflowers from seed, most sunflower plants take 70–100 days from the time you sow the seed until sunflower heads bloom. Smaller varieties are usually fast growing and bloom earlier, while a giant sunflower takes longer.

Q: What are the best sunflowers to grow?

There are many types of sunflowers. The traditional giant sunflower can reach 12–15 feet tall, producing large seed heads packed with edible seeds. Small sunflower varieties are ideal for pots or borders. For continuous color, try succession planting with branching varieties. When deciding on sunflowers to grow, consider if you want cut flowers, acres of sunflowers, or seeds for roasting.

Q: How do I plant sunflower seeds?

To plant sunflower seeds, choose a sunny spot or use seeds in pots. Outdoors, sow sunflower seeds 6 inches apart for smaller plants or several inches apart for giants. Indoors, you can plant seeds indoors in pots and later transplant them along a fence or in beds. The best planting time is after the frost has passed.

Peace Lily Care Q&A

1. Why do peace lilies don’t bloom sometimes?

A: If your peace lily plant isn’t producing flowers, it may not be getting enough light. Peace lilies prefer bright, indirect light rather than low light if you want blooms. Try moving the plant closer to a bright window but avoid direct sunlight, which can scorch the leaves. Feeding during the growing season with a balanced houseplant fertilizer can also help keep your peace lily blooming.

2. What is the best watering schedule for peace lilies?

A: To water your peace lily correctly, wait until the top inch of soil feels dry before watering. In warmer months, your watering schedule may be once a week, while in cooler months it’s less frequent. Always use a pot with drainage holes and empty the saucer after watering to prevent the plant from sitting in water, which can cause root rot.

3. Can peace lilies grow indoors in low light?

A: Yes, peace lilies thrive indoors and are considered an easy plant to grow, even in low light. However, blooms may be fewer. For a beautiful peace lily with more flowers, place it where it gets bright light but avoid direct sunlight to keep the large leaves healthy.

Indoor Garden Ideas Q&A

Q: How do I start an indoor garden in a small space?

A: Start small by choosing easy-to-grow potted plants or herbs that thrive indoors. Use vertical space with shelves or hanging plants to maximize floor space. For limited areas like apartments or home offices, compact container gardening works best.

Q: What are the best plants to grow indoors?

A: Low-maintenance plants like peace lilies, rubber plants, trailing plants like pothos, and indoor trees such as the fiddle leaf fig are among the best indoor options. They adapt well to indirect light and are easy to care for.

Q: What are the easiest herbs to grow indoors?

A: Herbs like basil, mint, parsley, and thyme are some of the best herbs to grow indoors. They grow well on sunny windowsills or under LED grow lights, especially during the winter months when natural light is limited.

Q: Can I grow vegetables indoors?

A: Yes, indoor vegetable gardening is possible with the right setup. Leafy greens, cherry tomatoes, and radishes are great vegetables to grow indoors. Use containers with drainage holes, provide enough light (natural or LED grow lights), and water when the soil feels dry to avoid root rot.

Q: What’s the best lighting for growing plants indoors?

A: Plants that are easy to grow still need adequate lighting. If your space lacks natural light, using grow lights (especially LED grow lights) can mimic sunlight, ensuring gardening success even during darker seasons.

Growing sweet potato slips is a rewarding gardening activity that ensures a bountiful harvest of this versatile and nutritious root vegetable. Slips are the shoots that grow from a mature sweet potato and are used to propagate new plants. There are various methods to growing sweet potato slips, and this guide will walk you through each method in detail.

I recall my first attempt at growing sweet potato slips. It was a hot summer, and I was eager to see if I could nurture them successfully. I tried different methods, like suspending sweet potatoes in jars of water and planting them directly in soil. Each method taught me something new about patience and resilience.

In this article, we will cover the water method, the outdoor soil method, and the indoor soil method, providing step-by-step instructions for each.

When to Start

Timing is crucial when growing sweet potato slips. Sweet potatoes thrive in warm weather and need a long growing season, typically around 90 to 170 days, depending on the variety. It's essential to start the slip-growing process 8-12 weeks before the last expected frost date in your area. This will ensure that your slips are ready for planting when the weather is warm enough for sweet potatoes to grow.

Materials Needed

Before starting the process, gather the following materials:

Mature sweet potatoes (preferably organic and untreated)

These serve as the source for your sweet potato slips. The mature sweet potatoes will sprout shoots or "slips" that can be propagated to grow new sweet potato plants.

Clean water (for water method)

Water is essential for encouraging the development of sweet potato slips. It provides hydration and promotes the growth of roots and shoots.

hand pouring a clean glass of water

Glass jars or cups (for water method)

These are used to suspend the sweet potatoes partially submerged in water. Glass containers are preferred as they are inert and won't react with the water or sweet potatoes.

Potting soil (for indoor and outdoor soil methods)

Potting soil is used when transplanting the rooted sweet potato slips into individual pots or containers. It provides the necessary nutrients and support for the slips as they continue to grow.

a shallow container for planting

Shallow containers or trays (for water and indoor soil methods)

These are used to hold the sweet potato slips while they develop roots in water or potting soil. They provide a stable base for the slips and help contain any mess or water runoff.

garden soil for raised bed and trowel

Garden soil or raised beds (for outdoor soil method)

If you choose to grow sweet potato slips directly in the soil outdoors, you'll need garden soil or a prepared raised bed. This soil should be loose, well-draining, and fertile to support healthy growth.

grow lights used for plants

Grow lights (for indoor soil method)

If you're growing sweet potato slips indoors using the soil method, grow lights may be necessary to provide adequate light for proper growth. Sweet potatoes require plenty of sunlight, and grow lights can supplement natural light, especially if you don't have access to a sunny window.

hand holding gardening spray bottle

Spray bottle (for indoor soil method)

A spray bottle is useful for misting the soil and foliage of indoor sweet potato slips. It helps maintain proper humidity levels and prevents the soil from drying out too quickly.

Labels or markers (optional, for all methods)

Labels or markers can be used to identify different varieties of sweet potatoes or to keep track of planting dates and other important information. They help with organization and ensure you know what you're growing and when.

Methods for Growing Sweet Potato Slips

1. Water Method

The water method is a popular and straightforward way to grow sweet potato slips in water. Here's how to do it:

  1. Select Sweet Potatoes: Choose healthy, mature sweet potatoes. Organic sweet potatoes are ideal because they are less likely to be treated with sprout inhibitors.
  2. Prepare the Potatoes: Wash the sweet potatoes thoroughly to remove any dirt. Cut the sweet potatoes in half if they are large.
  3. Insert Toothpicks: Insert three to four toothpicks around the middle of each sweet potato half. The toothpicks will act as supports to suspend the sweet potato in water.
  4. Suspend in Water: Fill glass jars or cups with clean water. Place each sweet potato half into a jar, with the pointed end facing down and the toothpicks resting on the rim of the jar, suspending the bottom half of the sweet potato in the water.
  5. Location: Place the jars in a warm, sunny location, such as a windowsill. Sweet potatoes need warmth and light to sprout.
  6. Water Maintenance: Change the water every few days to prevent mold and bacteria growth. Ensure the sweet potatoes remain partially submerged.
  7. Wait for Slips to Grow: In a few weeks, shoots (slips) will begin to grow from the top of the sweet potato. These slips will have leaves and roots.
  8. Harvest the Slips: When the slips are 6-12 inches long, carefully twist or cut them off the sweet potato. Remove the lower leaves and place the slips in water to develop roots if they haven't already.
  9. Prepare for Planting: Once the slips have developed roots, they are ready to be planted in the garden or containers.

2. Outdoor Soil Method

The outdoor soil method involves planting the sweet potatoes directly in the soil to encourage slip growth. This method is suitable for gardeners with access to garden space or raised beds. Here's how to do it:

  1. Prepare the Garden Bed: Choose a sunny location with well-draining soil. Sweet potatoes prefer loose, sandy soil. Amend the soil with compost or organic matter to improve fertility and drainage.
  2. Plant the Sweet Potatoes: Bury the sweet potatoes horizontally about 2 inches deep in the prepared garden bed. Space the potatoes about 12-18 inches apart to allow room for slip growth.
  3. Water Regularly: Keep the soil consistently moist but not waterlogged. Sweet potatoes need regular watering to encourage sprouting.
  4. Mulch the Bed: Apply a layer of mulch around the sweet potatoes to retain moisture and suppress weeds.
  5. Wait for Slips to Grow: In a few weeks, slips will begin to emerge from the buried sweet potatoes.
  6. Harvest the Slips: When the slips are 6-12 inches long, carefully cut or pull them off the sweet potato. Ensure each slip has roots before transplanting.
  7. Prepare for Planting: The slips are now ready to be planted in their final growing location. If the slips don't have roots, place them in water until roots develop.

3. Indoor Soil Method

The indoor soil method is ideal for gardeners who want to start slips indoors before the outdoor planting season. This method allows for better control over growing conditions. Here's how to do it:

  1. Prepare Containers: Fill shallow containers or trays with potting soil. Ensure the containers have drainage holes to prevent waterlogging.
  2. Plant the Sweet Potatoes: Bury the sweet potatoes horizontally about 2 inches deep in the potting soil. Space the potatoes about 6 inches apart.
  3. Water Lightly: Water the soil lightly to keep it moist but not soggy. Use a spray bottle to avoid overwatering.
  4. Provide Warmth and Light: Place the containers in a warm location, ideally between 70-80°F (21-27°C). Use grow lights to provide 12-14 hours of light per day if natural sunlight is insufficient.
  5. Maintain Moisture: Keep the soil consistently moist by watering as needed. Use a spray bottle to maintain humidity around the plants.
  6. Wait for Slips to Grow: In a few weeks, slips will start to grow from the sweet potatoes.
  7. Harvest the Slips: When the slips are 6-12 inches long, carefully twist or cut them off the sweet potato. Remove the lower leaves and place the slips in water to develop roots if necessary.
  8. Prepare for Planting: Once the slips have developed roots, they are ready to be transplanted to their final growing location.

Harvesting Sweet Potatoes

Sweet potatoes are typically ready for harvest 90-170 days after planting, depending on the variety. Here are the steps for harvesting sweet potatoes:

  1. Check for Maturity: The foliage of sweet potatoes will start to yellow and die back when the tubers are mature. This is a sign that the sweet potatoes are ready to be harvested.
  2. Dig Carefully: Use a garden fork or trowel to carefully dig around the plants, starting about 12 inches away from the base to avoid damaging the tubers. Lift the sweet potatoes out of the soil gently.
  3. Cure the Sweet Potatoes: After harvesting, sweet potatoes need to be cured to improve their flavor and storage life. Place the sweet potatoes in a warm, humid location (85°F or 29°C and 85-90% humidity) for about 10 days.
  4. Store the Sweet Potatoes: After curing, store the sweet potatoes in a cool, dry place (55-60°F or 13-16°C) with good ventilation. Properly cured and stored sweet potatoes can last for several months.
