Seeing Wheel Bugs in Your Garden? It’s a Good Thing!

You may have seen this around your garden and home and thought “eeewwww”, what is that ugly thing? That, my dear, is a wheel bug and not to be feared unless they bite you. They are a generalist predator and love to feast on the dreaded spotted lantern fly, which is a good thing! Often known as assassin bugs they sport a dagger-like, piercing-sucking beak. They feast on something small like an aphid right up to something the size of a caterpillars. The wheel bug can reach up to 1 1/2 inches in length but don’t mess with them because if they bite you they can pack quite a punch. Avoid using broad-spectrum pesticides because this is one bug you want in your garden. We’ve posted photos of wheel bug eggs compared to the eggs of the spotted lantern fly so you can identify the one to seek out and destroy. Photos courtesy of U. of Md. Entomology Dept.

Know Which Bees Not to Mess With!

PSA for today: If you see a beekeeper run, then you should probably run too! 🐝🐝 Love and respect the bees, they are so important but know which ones not to mess with.

Test Your Soil Before Planting This Season!

We are often asked about soil testing. Univ. Of. Maryland no longer offers this service, but they have provided a list of labs that currently offer comprehensive soil tests.
  • Have your soil tested before planting a vegetable or flower garden, trees, and shrubs, or starting or renovating a lawn.
  • Soil testing labs provide more complete and accurate results than do-it-yourself soil test kits.
  • Soil test results give you baseline information on soil pH, nutrient levels, and organic matter content and recommendations for fertilizing and adjusting soil pH. Soil testing is an essential tool for improving soil health.
  • Soil testing helps reduce overfertilizing, keeping excess nutrients (nitrogen and phosphorus) out of Maryland’s groundwater and surface waters.
  • Vegetable gardens, regardless of location, should be tested for lead (Pb).

We came in today and it looks like the Leprechauns made a delivery, OXALIS! Super easy to grow and another plant that can live with proper care for years. And what is proper care you ask? Well, it’s actually pretty simple. A degree in horticulture is not required to grow this happy little plant. Oxalis has a fun personality all its own. Triangular leaves in shades ranging from emerald green to deep maroon and some are even variegated. You’ll also find some varieties sporting an extra leaf for good measure, just like the lucky four-leaf clover. 🍀 Oxalis are members of the wood sorrel family and are not true “shamrocks”, even though they are more readily available around St. Paddy’s Day. They like a well-drained soil and care should be taken to not overwater. Oxalis are grown from bulbs (corms) and they can rot if overwatered. They like to be placed in an area with bright but indirect light. Low light can make them leggy (and ugly ☹️). Fertilize with a well balanced all purpose food about every 2- 3 weeks when they are actively growing. They do occasionaly have a few nuisance pests like aphids, whiteflies, and spider mites. All in all a great little plant to have in your collection, and one that can provide years of enjoyment. So come on in, and see if you can find one that has a lucky leaf. If you do, it’s calling your name!


“The hills are alive with……no, not music, Hellebores! Our hellebores are waking up! They’re not out on the sales tables yet so come and take an early peek and get the best ones. They don’t mind a chill so they’re ready to go. A sure sign of Spring!

African Violets

African violets, the memories they bring back of the writer’s “Granny” growing huge and beautiful violets. All while making it look so easy, which it actually is! Today stunning colorful tri-color violets came in to the gift shop. These little beauties will certainly perk up the remaining gray days of winter. With proper TLC they will be repeat bloomers for many years to come, that’s right, we said YEARS! Here are a few tips for growing violets and if you feel overwhelmed come on in and we can answer any questions or concerns you have.

Avoid plants with soft, droopy leaves and those with brown spots or pests. Plants with a few open flowers and many closed buds will remain in bloom longer after you buy it. Tip: peek under the upper leaves to look for newly forming flower stems.

African violets need bright light to bloom, but cannot tolerate hot, direct sun because their leaves are easily scorched by intense light. Violets bloom best at temperatures from 65 to 75 degrees.

In the winter, violets grow best in south, east, or west-facing windows. On cold winter nights, move the plants away from the glass to a spot that remains above 55 degrees. When the sun gets stronger in the spring, move plants to a cooler east or even north-facing window.
Give each plant a one-quarter turn clockwise every few days to keep the growth symmetrical.

Watering is not as complicated as one would think. Water only when the soil surface feels dry. The pot may feel “light”.
Use room-temperature tap water. Cold water shocks the roots and causes leaf spots.
Let chlorinated water sit overnight before using.
Avoid softened water, which is too salty.
Water from the top or bottom, whichever is easier. Soak the soil thoroughly.
Let the pot drain completely; don’t let plants sit in water!
Try to avoid splashing water onto the leaves and never water directly onto the leaves. Use a high quality violet food, we recommend Espoma Organic African Violet Food.

Violets prefer a well-draining potting soil. Try to find a potting soil with a loose peat perlite mix. When you repot from a nursery pots, remember that the new pot should be about one-third to half the diameter of the plant. For example, a 7-9″ plant should be in a 3″ pot. A 9-12″ plant goes into a 4″ pot. Choose shallow pots for best drainage and root aeration. Repot your plant in fresh soil and a clean pot once a year.
Violets are very easily propagated. Often a healthy leaf allowed to root in a glass of water will produce another violet that you might want to pass along to a friend or family member.

Spacing is important. Try to keep your violets from touching each other and to allow for good air circulation around the plants.
When you see the blooms on your violet start to die simply reach in and pinch that bloom off as close to the plant as possible. Nothing makes a violet look more sad than dead flowers.

Violets can be susceptible to some pests, like Aphids and Mealy Bugs. Most pests can be easily treated. If you notice something unusual on your plant, please bring us a photo and we will do our best to diagnose and offer suggestions for treatments. Sadly, there are times when the best we can offer is “last rites” for the plant. But that’s okay, just buy a new one and start over!

Violets, or houseplants in general, are a fun and rewarding hobby!

Plants for Privacy

“What can I plant to screen the neighbors?” is a question we hear year round. While there are many conditions to consider, here are some of our favorite picks.

Pruning Hydrangeas

From our friends at Espoma, here is a great guide to pruning hydrangeas. Of course, we are always available at the garden center to answer any questions.
YOUR GUIDE TO FALL HYDRANGEA CARECaring for your hydrangea can make all the difference for next year’s blooms. Hydrangea’s are strong and can come back from almost anything when given enough time and proper care.

Just follow these fall tips for pruning and maintenance. It isn’t complicated.


It is important to identify your variety first because some hydrangea varieties do not like being pruned in the fall.

If your garden has hydrangeas, then you need to know that there are two types of hydrangeas. One type produces flower buds on old wood and the other produces flower buds on new wood. Stems are called old wood if they have been on the plant since the summer before. New wood are stems that develop in the current season.  Most varieties found in gardens are old wood bloomers including Mophead, Big Leaf, Lacecap, and Oakleaf hydrangeas. Double check your variety with your local garden center.

When to Prune

Hydrangeas can grow for years without being pruned, but if they get unruly, over take an area of the garden or lose their growing capabilities – it is time to trim. But when to prune them?

Prune fall blooming hydrangeas, or old wood bloomers, after they bloom in the summer. If you prune old wooded hydrangeas in fall, you are cutting off next seasons blooms.

Summer blooming hydrangeas, or those that bloom on new wood, are pruned in the fall, after they stop blooming.

Hydrangeas are colorful and vibrant in the early season, but are hard to preserve after being cut. They are easier to care for after they start drying on the bush.

How to Prune

Near the bottom of your plant, you will see thin, wispy, weak growth. Cut those down. They will take up energy that your plant could use for blooms.

Look for any dead stumps on your stems. They will not have grown any new wood or buds out of the original old wood. Cut the dead stumps down to their base to completely remove them. This will allow the new growth underneath to have a chance to succeed.

Dead and old blooms need to be removed to make room for new buds to come through. Cut the flower head off right above the first few leaves to encourage blooms for the next summer.

Stand back from the plant and observe its shape. You’ll want to prune the shrub into the shape you prefer, a sphere is the typical style but you could prune it into any shape you want!

Clean the Debris

Remove any debris that fell off from the base of the plant. You want to make sure your soil is free of any weeds, leaves and dead flowers.


If you’re growing blue hydrangeas, feed with Holly-tone to keep the soil acidic and the blooms bright. Otherwise, opt for Flower-tone.

For the best hydrangea care, feed 2-3 times throughout the growing season, which is from spring until fall.

Follow these few steps and your hydrangeas will be happy and vibrant for years to come.
