Garden World’s Guide to Gardening - Summer Houseplant Care!

Houseplants may love warm weather, but summer’s intense sun and heat can still take a toll. Even tropical varieties can suffer when conditions become too harsh. If you’re seeing wilting, yellowing, or brown patches on leaves, your plant may be stressed — or even sunburned. A little extra care goes a long way this time of year.

What’s Bugging You

Houseplants can be prone to pests in the summertime. Keep an eye on them and if you see any insects, cobwebs or white powdery substances, take action. Sometimes it’s enough to take them outside and wash them off with a gentle stream of the hose. If it persists, use an insect spray or neem oil. Remove any dead leaves or other debris from the soil surface to prevent mildew and other disease.

Shower Them

Nothing is better than fresh air flowing through open windows on a cool summer day. The downside is that a lot of pollen, air pollutants, and dust blow in and build up on plant leaves. That makes it hard for plants to breathe and absorb sunshine. Wipe off foliage with a damp cloth every couple of weeks or give them a soft shower. They will love getting a deep watering, lots of humidity and having clean fresh leaves. After the shower, give the plants some time to drip dry. This allows the water to completely drain out of the pot too.

Nature’s Vitamins

This is the perfect time to feed your plants. In spring and summer it’s a good idea to keep plants on a regular feeding schedule with an organic liquid fertilizer. Feeding after watering helps ensure that the plant food doesn’t just run out of the pot. Moist soil is better at absorbing the food.
