Snapdragons require 1 inch of water each week. To provide this, water snapdragons once per week until the soil is moist to a depth of 1 inch (25 mm). Watering needs may increase during hot, dry periods. So, it’s best to regularly check the soil moisture where your snapdragons are planted. If the top 1 inch of soil is dry, your snapdragons need water.
How Much Water Do Snapdragons Need Per Day?
Snapdragons only require daily watering when they are seedlings or have just been transplanted. If you are caring for new snapdragons, water lightly every day. Provide just enough water to keep the top ½-inch (13 mm) of soil moist. Avoid making the soil muddy. Continue this daily watering for two weeks.
- Only snapdragon seeds and newly planted snapdragons require daily watering.
- When watering daily, water until the top ½-inch (13 mm) of soil is moist.
- 2 weeks after planting, reduce watering to 1 time per week.
- Do not water established snapdragons daily.
Once your Snapdragons have been in place for two weeks, reduce your watering frequency to once per week. Established snapdragons do not need daily watering. Watering them too frequently can actually harm these plants. So, only use daily watering for young snapdragons.
How Do You Water Snapdragon Flowers?
Water established snapdragons once per week. Provide enough water to moisten the soil to a depth of 1 inch (25 mm). Never allow the water or dirt to splash onto snapdragon leaves or flowers during watering. This can invite disease. Instead, water at ground level with a soaker hose or watering can.
- Provide snapdragons with 1 inch (25 mm) of water per week.
- Water once weekly.
- Water until the soil is moist to a depth of 1 inch.
- Potted snapdragons may require two weekly waterings.
While snapdragons planted in the ground benefit most from once-weekly watering, potted snapdragons have slightly different needs. Potting soil dries out more quickly, so it’s often necessary to water potted snapdragons twice each week. Follow the same process for in-ground snapdragons. Moisten the soil with water until it is moist to a depth of 1 inch.
Do Snapdragons Like Wet or Dry Soil?
Snapdragons are tricky flowers that do not grow well in wet or dry soil, so monitor conditions like sun exposure. Instead, these tender perennials require slightly moist soil. If the ground gets too dry or too wet, your snapdragons will suffer. So, it is essential to keep the right moisture balance.
- Snapdragons struggle if the soil becomes too wet or too dry.
- Soil should be kept slightly moist at all times for snapdragons.
- Use this moisture meter to make sure the top inch (25 mm) of soil is always slightly moist.
Snapdragons love neutral soil that is neither dry nor wet. After watering, the soil should feel cool and damp. Once the soil surface begins to dry and crack, conditions are becoming too dry. This is the perfect time to check the soil moisture in case you need to water again. You can push your finger 1 inch (25 mm) into the soil to check for dryness or use a moisture meter. Either way, it’s important to check the soil often to keep it at the ideal moisture level for snapdragons.
Can You Overwater Snapdragons?
Snapdragons can easily be harmed by overwatering. If your snapdragons turn yellow and begin to flop over, they are being overwatered. Too much water can also cause fungal disease and mildew to attack your snapdragons. If your plants are yellowing and wilting, reduce watering immediately. If there are black spots or fuzzy mildew, spray the snapdragon with this neem oil spray to kill off the infection.
- It is easy to overwater snapdragons.
- Yellowing leaves and floppy stems mean your snapdragon is overwatered.
- Black spots on leaves mean your snapdragon has gotten too much water.
- Let the soil dry to a depth of ½-inch (13 mm) if your snapdragon is overwatered.
When watering your snapdragons, restraint is essential. Do not water until the ground becomes muddy or has visible pools of standing water. Water with a slow-acting soaker or hose, or add a little bit of water into the soil at a time with a watering can. Allow for the water to soak in before adding more. Always use your finger or a moisture meter to make sure the soil has been moistened down to 1 inch in depth. Once the water reaches this saturation depth, stop watering.

How Do You Know If Snapdragons Need Water?
Dry, curling leaves that begin to turn brown or yellow are a sure sign your snapdragon needs water. If the problem is very bad, your snapdragon may begin to wilt and fall over. Additionally, if your snapdragon isn’t receiving enough water, it may lose leaves, buds, and flowers.
- Foliage is dry or starts curling.
- Leaves begin to turn yellow or brown.
- Sudden loss of leaves, flowers, or buds.
- The soil surface is dry or cracked.
- When you poke your finger into the soil, it is dry at a depth of 1 inch (25 mm).
Check the soil if you see any signs of drought damage to your snapdragon. The signs of too much water and too little water can be similar in some cases. However, if the soil is dry at a depth of 1 inch (25 mm), your snapdragons need more water. Dry soil or a cracked soil surface are common indicators that the ground isn’t moist enough for your snapdragons.
Do Snapdragon Flowers Require Lots of Water?
Snapdragons do not require a lot of water but they do struggle in dry conditions. To properly water snapdragons:
- Water snapdragon seedlings and new transplants daily for 2 weeks.
- Once garden snapdragons are established, reduce watering to once weekly.
- Potted snapdragons need twice-weekly watering.
- At each watering, slowly water until the soil is moist to a depth of 1 inch (25 mm).
- Water snapdragons as soon as the top inch of soil is dry.
- Yellow leaves, floppy stems, and wet soil are signs that snapdragons are overwatered.
- Dry leaves, wilting, and cracked soil show that snapdragons are suffering from drought.
Now that you know the proper watering care for snapdragons, it will be much simpler to diagnose when your flowers need more water. Look out for the common signs that snapdragons are struggling and monitor soil conditions closely to keep your plants healthy.
