DIY Weed Killers Q&A

Frequently Asked Questions:

1. Will vinegar kill all weeds?

Vinegar is effective at killing most young, tender, and shallow-rooted weeds such as chickweed or small annual weeds. The acetic acid in vinegar dries out the plant’s leaves and stems, causing them to wither. However, it’s less effective against deep-rooted or perennial weeds like dandelions, crabgrass, or thistles. These tougher weeds may require repeated applications, higher-strength vinegar, or a combination of vinegar spray with manual removal to fully eliminate them.

2. Can DIY weed killers harm grass and plants?

Yes. DIY weed killers such as vinegar, salt, and boiling water are non-selective, meaning they don’t distinguish between weeds, grass, or flowers. If they come in direct contact with your lawn, vegetable plants, or ornamental flowers, they can cause scorching, yellowing, or even death. To avoid harming desirable plants, apply these solutions carefully and directly on weeds, ideally with a spray bottle or by shielding nearby plants with cardboard or plastic during application.

3. Is homemade weed killer safe for pets?

Generally, yes—when used properly. Unlike chemical herbicides, homemade options like vinegar, salt, or boiling water don’t leave behind long-lasting toxic residues. Pets and children can safely return to treated areas once the vinegar has fully dried or the boiling water has cooled. However, concentrated vinegar (horticultural vinegar with higher acidity) can cause skin or paw irritation if touched while wet, so always let the treated area settle before allowing pets back.

4. How long does it take for natural weed killers to work?

Natural weed killers typically show visible effects within 24 hours. Weeds may start to wilt, turn brown, or dry up soon after application, especially in hot, sunny, and dry conditions, which speed up the process. For tougher weeds or cloudy weather, results may take longer, and you may need to reapply for complete control. Keep in mind that these methods work best on small or actively growing weeds, not large established ones.

5. Are these solutions permanent?

No, most DIY weed killers are not a permanent fix. While they kill the parts of the weed above the soil, many weeds—especially perennials—can regrow from seeds or deep root systems. To maintain a weed-free garden, combine these natural treatments with preventive strategies such as mulching, pulling weeds before they seed, applying corn gluten meal to block germination, or maintaining dense, healthy plant cover to crowd out weeds naturally.

Planting and Growing Banana Trees Q&A

Q: Can I grow a banana tree indoors?

Yes, you can grow a banana tree indoors, especially if you choose dwarf varieties such as the Dwarf Cavendish. These smaller banana plants can thrive in large pots, provided they receive plenty of sunlight—ideally near a south-facing window—or supplemental grow lights. Indoor banana plants also benefit from high humidity, so regular misting or the use of a humidifier can help them flourish. With proper care, indoor banana trees can produce lush tropical foliage and, in some cases, even fruit.

Q: Do banana plants grow from seeds?

Most edible banana varieties, such as Cavendish, are seedless and cannot be grown from seeds. Instead, they reproduce through suckers (also called pups) that grow around the base of the plant. However, wild banana species do produce large, hard seeds that can be germinated. These seed-grown bananas are not commonly cultivated for eating, as their fruit is often filled with seeds and lacks the sweetness of cultivated varieties.

Q: How long does it take for bananas to fruit?

Banana plants typically take between 9 to 15 months from planting to produce fruit, although the exact time depends on the variety, climate, and growing conditions. They grow fastest in consistently warm temperatures with high humidity and fertile soil. Once the flower stalk emerges, it usually takes another 2 to 6 months for the bananas to mature and be ready for harvest.

Q: Do banana trees die after producing fruit?

Yes, the main stem of a banana plant, often called the "mother plant," dies after it produces fruit. However, the plant doesn’t completely die out—it produces new shoots or suckers at the base. These suckers grow into new plants, continuing the cycle. Gardeners often select the healthiest suckers to grow into the next generation of fruit-bearing plants, ensuring a continuous supply of bananas.

Q: Can bananas survive winter?

Banana plants are tropical and do not tolerate frost or freezing temperatures. In regions with cold winters, they must either be grown in pots and brought indoors before the first frost or protected outdoors with heavy mulching and wrapping. Some cold-hardy ornamental varieties can withstand cooler temperatures, but fruit-bearing types generally need a warm, frost-free climate to survive and produce well.

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.

How to Plant Squash in Containers

Planting squash in containers is a great way to grow this vegetable in your garden, especially for those with limited space or who want to grow squash in a pot. With the right steps, you can easily cultivate different varieties of squash and enjoy fresh produce even in small spaces. Follow these instructions to successfully grow squash in containers.

1. Choose the Right Container

Select a container that is at least 12-18 inches deep and has a diameter of 18-24 inches. Larger containers are better for giving squash roots enough space to grow. Make sure the container has drainage holes at the bottom to allow proper water flow. A container that is large enough to fit one squash plant will give your squash enough room to thrive.

2. Prepare the Soil

Use a well-draining potting mix with plenty of organic matter to feed squash plants and provide them with the nutrients they need. If you’re new to growing squash, consider adding compost or aged manure to the soil to improve its fertility. These soil preparations are crucial for successful squash growth. For squash varieties to grow, look for those that are known to do well in containers, such as bush varieties that require less space.

3. Plant from Seed or Seedling

  • From Seeds: If you’re planting squash from seeds, sow them directly into the container about 1-2 inches deep. Space the seeds 2-3 inches apart to allow enough room for the plants to grow. Once the seedlings emerge, thin them to one squash plant per container to avoid overcrowding.
  • From Seedlings: If you're using seedlings, gently remove them from their original pots, ensuring that the roots are not disturbed. Place the seedling in the container, making sure the top of the root ball is level with the surface of the soil. Be sure to choose squash varieties that are suitable for container planting.

4. Water Well

After planting, water the soil thoroughly to settle the soil around the roots. Keep the soil consistently moist, but not soggy. Squash plants require regular watering, especially when the plant was growing and starting to establish itself. Proper watering ensures the roots are developing well, setting the foundation for future growth.

5. Support the Plant (If Needed)

For vining squash varieties, consider installing a trellis or tomato cage immediately after planting to support the plant’s growth. Train the vines to climb upward, which will save space and help prevent damage to the leaves and fruit.

Squash Planting Requirements

To successfully grow squash in pots, it's important to understand the specific requirements of both summer squash and winter squash varieties. These squash plants thrive in vegetable container gardens and can be grown in a range of conditions, whether you're using vegetable container options or growing squash vertically on a garden trellis.

Soil

Squash prefers well-draining, fertile garden soil. For growing squash in pots, it’s essential to use high-quality potting mix or kitchen garden soil, as this will provide the necessary nutrients for squash vines to thrive. The container should be large enough to allow for proper root growth—generally, a container with a 2-3 inch size in depth works well. The larger the container, the better, as it ensures that the squash plant has enough space to spread its roots and grow. Make sure there are holes in the bottom of the container to allow excess moisture to escape, preventing waterlogged conditions that can lead to unhappy squash plants.

Water

Squash plants require consistent moisture, especially during hot, dry periods. Deep watering is essential to encourage strong root development, which helps the plant withstand drought. Aim for approximately 1-1.5 inches of water per week, either from rainfall or supplemental watering. It’s important to water the base of the plant, avoiding wetting the leaves, as damp foliage can create conditions that promote fungal diseases like powdery mildew. Consider using a drip irrigation system or soaker hose to keep the water focused on the soil.

Temperature and Humidity

Squash thrives in warm weather, with ideal temperatures ranging from 70°F to 85°F (21°C to 29°C). Plant squash after the last expected frost in your area to ensure the soil is warm enough for germination. Frost can damage young plants, so it’s important to wait until temperatures remain consistently above freezing. While squash plants do enjoy warmth, they are sensitive to excessive humidity, which can encourage fungal growth. A moderate level of humidity is best to maintain plant health, ensuring good airflow and preventing conditions that favor disease development.

Sunlight and Location

Squash plants need full sun to grow vigorously and produce abundant fruit. Ensure that your squash plants receive at least 6-8 hours of direct sunlight per day. If you're growing squash in containers, place them in a sunny location, such as a south-facing balcony or patio, to promote healthy photosynthesis. A sunny spot helps the plant produce the energy it needs for robust growth and strong fruit production. Avoid shaded areas, as insufficient sunlight can result in poor yields and weak plants.

Maintenance Tips for Squash in Containers

Maintaining healthy squash plants in containers requires ongoing care, including fertilization, pruning, and occasional repotting.

Fertilization

Squash plants are considered heavy feeders, meaning they require plenty of nutrients to grow strong and healthy. To ensure your squash thrives, use a balanced, slow-release fertilizer that provides essential nutrients like nitrogen, phosphorus, and potassium over time. Compost is also a great option, enriching the soil with organic matter and promoting healthy growth. Apply fertilizer at planting time, and then reapply every 3-4 weeks during the growing season. Be cautious not to over-fertilize, as this can encourage excessive foliage growth, potentially at the expense of fruit development. It's important to follow the recommended dosage for the specific fertilizer to avoid any nutrient imbalances.

Pruning

Pruning your squash plants regularly helps improve air circulation and light penetration, reducing the risk of fungal diseases. Remove any dead, yellowing, or damaged leaves to prevent the plant from wasting energy on unhealthy growth. For vining varieties, it is especially beneficial to trim back the vines. By cutting the excess growth, you can focus the plant's energy on producing fruit rather than allowing the vines to sprawl aimlessly. Be sure to use clean, sharp pruning shears to avoid damaging the plant and reduce the risk of spreading disease.

Mulching

Mulching is an excellent practice for squash plants as it helps conserve moisture, suppresses weed growth, and maintains a stable soil temperature. Organic mulches, such as straw, grass clippings, or wood chips, are ideal for this purpose. Spread a 2-4 inch layer of mulch around the base of the plant, ensuring it doesn’t touch the plant’s stems directly. This not only helps in moisture retention but also prevents soil erosion and keeps the root system cooler during hot weather. Mulch also breaks down over time, adding organic material back into the soil, which further benefits the plant’s growth.

Potting and Repotting

If you're growing squash in containers, be mindful that they have relatively large root systems that may outgrow their pot. When the plant becomes root-bound—meaning the roots start circling around the edges of the container—it’s time to repot. Choose a larger pot that provides more room for growth, typically about 2-3 inches larger in diameter than the current container. Repotting is best done in early spring or at the beginning of the growing season when the plant is still in its early growth phase. Use fresh, well-draining soil and ensure the new container has proper drainage holes to prevent waterlogged roots.

Overwintering

In areas with cold winters, squash plants are typically grown as annuals, meaning they will not survive the winter months. However, if you'd like to try overwintering your squash, consider moving the plant indoors before the first frost. Place the container in a sunny spot with temperatures above 50°F (10°C). Be aware that the plant may enter dormancy during the winter months and won't produce fruit until the next growing season. Alternatively, you can opt to grow squash as an annual by planting new seeds each year. This allows you to harvest fresh squash every season without worrying about overwintering the plants.

Common Pests and Diseases of Squash

Squash plants are susceptible to several pests and diseases, including:

Aphids

Small, sap-sucking insects that can damage plants. Use insecticidal soap or a strong spray of water to control them.

Powdery Mildew

A fungal disease that appears as a white, powdery coating on the leaves. Remove affected leaves and improve airflow around the plant.

Squash Bugs

These pests can damage both the leaves and fruit of the squash plant. Handpick them off or use insecticides as needed.

How to Harvest Squash

Harvesting squash depends on the variety and when it reaches maturity. For summer squash like zucchini, pick them when they are young and tender, about 6-8 inches long. Winter squash, such as butternut or acorn squash, should be harvested when their skin is hard and the vines begin to die back. Use a sharp knife to cut the fruit from the vine, leaving a few inches of stem attached.

Frequently Asked Questions:

Q: What is the best way to grow squash in containers?

A: To grow squash in containers, you’ll need a large pot (at least 12-18 inches deep) with good drainage. Choose a squash variety suited for container gardening, such as zucchini or summer squash, and use high-quality potting soil enriched with organic matter. Place the container in a sunny spot with 6-8 hours of sunlight per day, and keep the soil moist.

Q: Can I grow summer squash in a pot?
