April is a pivotal month for Swiss cheese plants. After a slow winter, they’re finally ready to do something impressive – and a handful of well-timed tasks right now is what makes that happen. This is the month to get things right before the real push begins, when the plant starts to ramp up its growth and produce bigger, more fenestrated leaves. But ‘fine’ and ‘thriving’ are pretty different things – and April is when that gap starts to show.
1. Bump Up Watering
Swiss cheese plants tend to be low-maintenance when it comes to watering, especially during the winter months. The root system is dormant, and the soil holds moisture longer, making it easy to forget to water them. However, April marks a significant change. The root system becomes active again, pulling more moisture from the soil, and the soil turns over faster than it did in February. As a result, the plant needs more water to stay healthy.
So, how do you know when it’s time to water your Swiss cheese plant? The best way is to check the soil moisture by inserting your finger into the soil up to the first knuckle. If the soil feels dry, it’s time to water. If it’s still damp, wait a few more days and check again. You can also use a moisture meter, like the Raintrip 4-in-1 Soil Meter, to get a more accurate reading. When you do water, make sure to soak the pot thoroughly and let it drain completely. A monstera sitting in a wet saucer is a root rot situation waiting to happen, even in spring when the plant is drinking more than usual.
It’s also essential to note that the frequency of watering will depend on the specific conditions of your plant. Factors like temperature, humidity, and light exposure can all impact the plant’s water needs. As a general rule, aim to water your Swiss cheese plant every 7-10 days, but be prepared to adjust based on the plant’s response.
Watering Tips:
- Check the soil moisture by inserting your finger into the soil up to the first knuckle.
- Use a moisture meter, like the Raintrip 4-in-1 Soil Meter, to get a more accurate reading.
- Soak the pot thoroughly and let it drain completely after watering.
- Adjust the watering frequency based on the plant’s response to changing conditions.
2. Move It Closer to the Light
Swiss cheese plants can survive in lower light conditions, but they don’t exactly thrive there either. In April, the light situation changes enough that it’s worth taking a fresh look at where the plant is sitting. Newer leaves coming in smaller than expected, or without the characteristic splits and holes, almost always point to a light issue. Bright indirect light is the target – a spot that gets good light for several hours without direct afternoon sun beating on the leaves.
East-facing windows are solid choices for Swiss cheese plants, as they receive gentle, indirect light throughout the day. South or west-facing windows also work, but be sure to provide some distance or a sheer curtain to filter the intensity. Avoid placing the plant directly in front of a south-facing window without some protection, as Monstera leaves can scorch faster than you expect.
If you’re struggling to find the perfect spot, consider using a sheer curtain or a sunshade to filter the light. The Yesus Sunshade mesh from Amazon is a great option for protecting plants on the hottest days. By moving your Swiss cheese plant closer to the light, you’ll encourage it to produce bigger, more fenestrated leaves and support its overall health.
Lighting Tips:
- Provide bright indirect light for your Swiss cheese plant, aiming for a spot with several hours of good light.
- East-facing windows are solid choices, as they receive gentle, indirect light throughout the day.
- South or west-facing windows also work, but provide some distance or a sheer curtain to filter the intensity.
- Avoid placing the plant directly in front of a south-facing window without some protection.
3. Start Fertilizing Again
Swiss cheese plants don’t need fertilizer during the winter months, as the plant isn’t actively growing. However, in April, the plant starts to ramp up its growth, and it needs a boost of nutrients to support its development. A balanced liquid fertilizer around 20-20-20, diluted to half strength, is an excellent choice for Swiss cheese plants. Apply it once a month through spring and summer, and watch your plant thrive.
One common mistake people make when fertilizing houseplants is applying the fertilizer to completely dry soil. This can concentrate the salts and scorch the roots, leading to browning leaf edges a few weeks later. To avoid this, give your Swiss cheese plant a plain water rinse first, let it drain, and then come back with the diluted feed. This will ensure that the fertilizer is absorbed by the plant, rather than building up in the soil.
Fertilizing Tips:
- Start fertilizing your Swiss cheese plant in April, using a balanced liquid fertilizer around 20-20-20.
- Dilute the fertilizer to half strength and apply it once a month through spring and summer.
- Avoid applying fertilizer to completely dry soil, as this can concentrate the salts and scorch the roots.
- Give your Swiss cheese plant a plain water rinse first, let it drain, and then come back with the diluted feed.
4. Clean the Leaves
Big leaves collect a surprising amount of dust, which can cut into photosynthesis and impact the plant’s overall health. A winter’s worth of buildup can be particularly problematic, especially when the plant is trying to ramp up its growth in April. To keep your Swiss cheese plant healthy, give it a good cleaning every now and then.
Using a damp cloth and plain water is all it takes to clean houseplants. Simply wipe down each leaf, supporting the back of the leaf while you do so to avoid putting strain on the stem. Be sure to flip the leaves over and check the undersides as well, as spider mites and scale tend to set up shop there. Catching these pests early is a quick fix with a damp cloth and a little neem oil. Left until summer, either can spread fast and take months to clear.
Cleaning Tips:
- Use a damp cloth and plain water to clean your Swiss cheese plant.
- Wipe down each leaf, supporting the back of the leaf while you do so to avoid putting strain on the stem.
- Flip the leaves over and check the undersides for spider mites and scale.
- Catch pests early with a damp cloth and a little neem oil.
5. Check the Roots and Consider Repotting
Two years in the same pot is about when it’s worth checking the roots of your Swiss cheese plant. If the roots are circling the inside of the pot or pushing out the drainage holes, it’s likely time to repot the plant. A root-bound Swiss cheese plant is unlikely to thrive, and repotting can give it the room it needs to grow.
When checking the roots, look for any signs of root rot, such as soft, mushy roots or a sour smell. If you find any of these signs, it’s best to repot the plant immediately. Use a well-draining potting mix and a pot that’s only slightly larger than the previous one. This will give the roots room to grow without overwhelming the plant.
Repotting Tips:
- Check the roots of your Swiss cheese plant every two years or so.
- Look for signs of root rot, such as soft, mushy roots or a sour smell.
- Repot the plant immediately if you find any signs of root rot.
- Use a well-draining potting mix and a pot that’s only slightly larger than the previous one.
Conclusion
April is a pivotal month for Swiss cheese plants. By following these five essential tasks – bumping up watering, moving the plant closer to the light, starting fertilizing again, cleaning the leaves, and checking the roots and considering repotting – you’ll give your plant the boost it needs to thrive. Remember, these tasks are not complicated, and it’s mostly just catching up to where the plant already is – adjusting a few things that have been on winter settings for too long. With a little care and attention, your Swiss cheese plant will reward you with bigger, more fenestrated leaves and a healthier, more vibrant appearance.
