What is nemesia?

Nemesia is a colorful flowering plant native to South Africa. It stays fairly small, typically only growing to around a foot tall, making it great for borders and edges. These flowers can grow as annuals or perennials, depending on the zone they are planted in, and they also make excellent container plants.

Pollinators love nemesia, and they are particularly attractive to bees and butterflies. While nemesia is most commonly found in bright shades of pink and yellow, there are also varieties with softer, more pastel colors. There are even some two-toned varieties of nemesia.

Planting nemesia

Nemesia can grow as a perennial in USDA zones 9 to 11, but it can also grow as an annual north of that. However, you can grow it indoors or in a greenhouse, no matter what zone you live in. Nemesia can grow in full sun or partial shade, but it can’t tolerate poor drainage. Make sure the soil is a well-draining type and light to avoid root rot and fungal problems.

If you live in an area with dense, clay-heavy soils, then you may want to grow your nemesia in a pot instead. Nemesia is tolerant of heat, salt, and drought. It is also nontoxic for people and pets, although nemesia isn’t generally considered good to eat.

Nemesia care

Nemesia plants appreciate soil that’s moist but not soggy. Depending on the weather, this means watering your nemesia once or twice a week. Indoor nemesia may need less frequent waterings, but make sure the pot is draining properly. If the drainage holes are clogged, water could build up in the soil and cause problems down the line.

Nemesia begins to slow down and go dormant when the temperature reaches the mid-50s. If it dips much further than that, it’s a good idea to bring your nemesia indoors if possible. If you can’t, consider covering your nemesia to protect it from frost damage. Nemesia plants don’t need to be pruned or deadheaded. However, some gardeners choose to deadhead their nemesia plants. Although it isn’t necessary, it encourages the plant to bloom again.

Common pests and diseases

The most common problem with nemesia plants, and the problem from which most of their common pests and diseases stem, is overwatering. Soggy soil and damp leaves lead to fungal infections such as root rot. Nemesia is also prone to leaf spot and other fungal infections. These fungal infections can attract fungus gnats and pests that feed on rotting plant matter, which is not a pleasant sight. Avoid all these problems by watering your nemesia only when the soil is dry, and avoid getting the leaves wet when possible.

Nemesia are beautiful, colorful flowers that will brighten up any garden or home. From pink to yellow to red and purple, these flowers come in a wide range of colors, so they’ll fit nicely no matter what type of aesthetic or theme you prefer. Nemesia are easy to care for, and all they need is sunshine and the occasional watering to flourish. With this care guide, you’re ready to fill your garden to the brim with nemesia flowers.

Outdoor gardens are bound to have outdoor creatures in them from time to time, but not all creatures are popular. While you might be delighted to see a bird or bunny in your garden (or feel distraught, if they’re eating your plants), many gardeners would be less excited to see a spider or snake. Snakes have an important role in our ecosystem, and they can even benefit your garden, but you might still wonder what exactly you should do if you see one. We’ll answer all your questions, so you’ll know what to do if you see a slithering intruder in your garden.
What to do if you see a snake

If you see a snake in your garden (or anywhere else), do not approach it. It’s easy to misidentify snakes, especially if they're moving quickly or partially hidden by plants, and even non-venomous snakes will bite if they feel threatened. Keep pets or children away from the area as well. In most cases, you can simply wait for the snake to leave with no further action.

Planting peonies

Peonies are most commonly found as bare root tubers (meaning just the tuber, without any soil) or are mature plants. Mature plants are easier to find later in the year and are usually sold as container plants. If you choose one of these, look for one that hasn’t fully bloomed yet. Flowers that are already fully open will fade more quickly, so choosing a plant with buds will help you get the most out of your plant.
