As a continuation to Monday's post, catmint is much more than just a natural mosquito repellent. It's also beloved by pollinators, such as honeybees, hummingbirds, and butterflies! Tiger swallowtails are said to particularly enjoy catmint, alongside snowberry clearwing moths.

The plants shown here are "Cat's Pajamas" catmint, by Proven Winners.

Warmer weather is unfortunately accompanied by the pests we all know and hate: mosquitoes. Fortunately, we have plenty of mosquito repellent plants in stock, like these catmint plants! According to a study from Iowa State University, catmint was found to be 10x more effective than the chemical DEET. Easy to care for but with the tendency to grow like a w**d, catmint is a very reliable way to keep those pesky mosquitoes out of your garden! 🌱

4 Tips for Dividing German Iris Like a Boss
Love irises and want to divide them? Read below!! From our friends are Dutch Bulbs!
Some dividing tips:
1. About four weeks after the flowers fade, cut down the foliage by about two-thirds.
2. Carefully dig up the clumps and gently separate individual rhizomes by hand or with garden shears.
3. Discard damaged or discolored rhizomes. Also, toss out any with soft spots.
4. Freshen soil with compost and replant the newly separated rhizomes 15-24" apart.
