Here are some homemade weed killers:

• VinegarMix one gallon of white vinegar with one tablespoon of dish soap and optionally one cup of salt in a container. Pour the mixture into a sprayer and apply to weeds, making sure to cover the leaves and stems. The vinegar's acidity dehydrates the weed, and the dish soap breaks down the plant's outer coat.
• SaltA non-toxic, non-selective option that kills weeds by poisoning them with sodium chloride.
• Boiling waterPour boiling water directly on weeds to destroy them and nearby greenery.
• Baking sodaA natural desiccant that sucks water out of weeds and their roots. It's a slow-acting method, but it can be effective if used early in the season.
• Rubbing alcoholMix two tablespoons of rubbing alcohol with four cups of water in a bowl, then spray the leaves of weeds. The ethanol-based liquid causes weeds to lose water.
• Lemon juiceThe citric acid in lemon juice dries out weed

How to Bring Dying Flowers Back to Life

1. Clean Your “Operating Room”
2. Cut the Stems.
3. Add Bleach to the Water to Kill Bacteria.
4. Add Sugar or Plant Food to the Water.
5. Trim Away Dead or Dying Foliage.
6. Keep Them Cool.

Watering dead grass won't bring it back to life, and in fact, it can make the situation worse by causing the roots to rot faster. Instead, you can try these steps to revive a dead lawn:

1. 1. Remove dead grassUse a rake in the spring to remove dead grass patches. You can also rake over bare spots to prepare the soil for new seeds.
2. 2. AerateLoosening the soil with aeration helps grass get the nutrients it needs to grow.
3. 3. DethatchRemove the layer of dead grass and debris called thatch that can build up over time. Removing thatch allows water to heal living grass and encourages new growth.
4. 4. Add compostSpread a thin layer of compost, about 1/2 inch thick, as topdressing.
5. 5. Add seedsUse a broadcast spreader to spread new seeds across the lawn, then lightly rake them into the topsoil.
6. 6. FertilizeSpread a starter fertilizer.
7. 7. WaterWater the lawn twice a day for the first two weeks, applying 1/4 to 1/2 inch daily. After the third week, gradually reduce watering frequency, and by the fourth or fifth week, return to your regular irrigation schedule.

A plant that looks dead may still have some life left. Here are some tips for reviving a dying plant:

• Trim dead leaves and stemsRemove dead leaves and stems with scissors or pruning shears so the remaining plant can get all the resources.
• WaterIf the soil is dry and the leaves are brittle, the plant needs water. Water until the soil feels damp, then immerse the plant in a shallow bowl of water for 10 minutes.
• Add humiditySome plants, like ferns, need more humidity than a living room can provide. Place a shallow pan of small rocks under the plant and add some water.
• RepotRepotting with fresh, well-drained soil can help revive a plant. However, repotting is stressful for plants, so it shouldn't be done too often.
• Adjust sunMove the plant to a more suitable location in your home. Keep water-damaged plants out of direct sunlight.
• Add nutritionYou can make homemade plant food with common household items. However, avoid adding fertilizer while the plant is struggling, as it can damage the roots. Instead, wait until the plant has fully recovered.

Here are some steps for transplanting a plant:

1. 1. Prepare the soilLoosen the soil so roots can breathe and penetrate deep into the soil.
2. 2. Water the plantWater the plant before removing it from its container to help the soil stick to the roots.
3. 3. Dig up the plantDig a hole that's slightly larger than the plant's container, and try to keep as much soil around the roots as possible.
4. 4. Inspect the rootsGently loosen any roots that are too concentrated at the bottom of the pot or completely cover the soil.
5. 5. Place the plantPosition the plant in the hole at soil level, or slightly higher if the soil is loose or sandy. For vegetables, bury the plant up to its first set of leaves.
6. 6. Firm the soilUse your hands to firm the soil around the plant. For vegetables, smooth the soil around the stem at a slight decline so water drains toward the plant.
7. 7. Water againWater the plant well to encourage root growth and help it settle into its new spot.
8. 8. Protect the plantCover the plant with lightweight cloth and stakes for about two days after transplanting to protect it from the elements
