Start seeds, grow in containers, and learn what your garden needs.
Search this topicAdult butterflies use nectar, while their caterpillars often depend on particular host plants for food. Choose both nectar flowers and hosts suited to butterflies in your region. A garden full of blooms may feed visiting adults without supporting their young. Expect some leaf feeding on host plants; that is part of their purpose.
Choose plants with overlapping bloom periods so nectar remains available from early through late season. Group suitable flowers together and include locally appropriate caterpillar host plants. Avoid relying entirely on highly doubled blooms, which may offer little accessible nectar. Observe which plants attract visitors and fill gaps in flowering the following year.
Identify the type and cultivar first. Many begonias are adapted to shaded conditions and can struggle in strong direct sun, but tolerance varies. Start with the plant label rather than applying one rule to every begonia. Choose a position with appropriate light and drainage, and watch for leaf scorching after a move outdoors.
Look for the name on the label and compare its growth with wax, tuberous, cane, and rhizomatous types. Cane begonias develop upright cane-like stems; tuberous types grow from storage tubers. The distinction matters for overwintering and propagation. A flower color alone is not enough to identify how the plant should be cared for.
Calibrachoa generally sheds its spent flowers without routine deadheading. Concentrate on sufficient sun, a well-drained potting mix, and appropriate feeding and watering. Hanging baskets can dry quickly, so check the mix regularly without leaving roots waterlogged. Removing every faded bloom is usually unnecessary, even though other flowering plants may benefit from that routine.
Calibrachoa is sensitive to root conditions and prefers an acidic, freely draining growing medium. A container makes those conditions easier to control than a heavy garden bed. Check drainage, moisture, and pH rather than repeatedly adding fertilizer. Choose a suitable potting mix and make sure the basket or pot has functioning drainage holes.
Plumed celosia has feathery flower spikes, while cockscomb types form crested, folded heads. Wheat types have a narrower grain-like flower shape. Choose according to the space and mature size on the label. Large cockscomb heads can be heavy enough to need support; the different shapes are normal varieties, not signs of disease.
Choose a warm, sunny position with well-drained soil. Match the cultivar's mature height to the bed so shorter plants are not shaded by taller neighbors. Celosia is commonly grown as a warm-season annual, so follow local frost guidance before setting it out. Good placement is more useful than trying to compensate for shade with extra feeding.
Some modern cultivars tolerate sun, while others perform best in shade. Check the named variety rather than assuming all coleus has the same needs. Acclimate plants gradually to their outdoor position and monitor moisture, especially in pots. A sun-tolerant selection still needs protection from cold and a growing medium that drains well.
Pinch the growing tip just above a leaf node once the young plant is established. This encourages side shoots instead of one long stem. Remove flower spikes if your goal is colorful foliage. Use clean tools and leave enough leaves for continued growth, then provide suitable light and steady moisture while new shoots develop.
Take a healthy stem tip about four to six inches long and remove the lower leaves. Put the bare lower stem in water while keeping leaves above the surface. Once roots develop, move the cutting into a suitable potting mix and keep it evenly moist during establishment. Use a healthy parent rather than propagating a struggling specimen.
It depends on the group and cultivar. Traditional Impatiens walleriana usually needs shade, while some New Guinea and selected hybrid types tolerate more sun. Read the label before choosing the location. Provide moisture with good drainage and wait for suitable warmth outdoors. Sun tolerance does not mean a plant can remain dry all day.
No. Traditional walleriana types have been particularly vulnerable, while New Guinea impatiens and some newer resistant selections offer different options. If the disease has been a problem, choose a clearly identified cultivar and seek local guidance before replanting. Do not assume every plant sold simply as impatiens has the same resistance.
Lantana generally performs well in sun, warmth, and a well-drained growing medium. It can tolerate drier conditions once established, but newly planted specimens still need attention to watering. Containers can help where garden drainage is poor. Check local suitability before planting, since a plant grown as an annual in a cold region behaves differently in warm climates.
Remove faded flower heads before they develop seed, taking off the spent bloom rather than only loose petals. This can encourage further flowering and remove heads that might rot in damp weather. Keep healthy foliage intact and inspect as you water. Marigolds can grow without deadheading, but regular removal often keeps the display tidier.
Check sunlight and feeding first. Marigolds need a sunny location, and excessive fertilizer can favor leafy growth at the expense of blooms. Stop adding feed automatically and assess the soil and product directions. Remove spent flowers and allow the plant time to respond; more fertilizer is not a reliable solution to a leafy, shaded plant.
Remove the spent flower together with the developing seed portion beneath it. Pulling away only the faded petals can leave the plant investing in seed production. Work carefully so nearby buds remain intact. Some varieties need less grooming, so also follow the cultivar's care instructions and maintain suitable light, water, and feeding.
Insufficient light can reduce flowering even when the foliage looks healthy. Petunias generally need several hours of strong sunlight and often bloom best in full sun. Move the basket gradually to a brighter suitable position, checking water needs as exposure increases. If the location must remain shady, choose a flower adapted to shade instead.
Wait until the risk of frost has passed, then sow in a sunny, well-drained location. Follow the variety's depth and spacing instructions; giant and branching types need much more room than compact ones. Keep the seed area moist during germination. Label the row so emerging seedlings are not mistaken for weeds.
Sow the same variety in successive small batches, or choose varieties with different days to flowering. Check that later sowings still have enough warm growing time in your area. Leave adequate space for each plant's mature size. One large sowing of a single-stem variety is more likely to produce a concentrated flowering period.
Choose a compact or dwarf variety and a container that provides adequate root space and drainage. Put it in full sun and check moisture more often than you would for plants in the ground. Read the expected mature height before buying seed; a giant sunflower can become top-heavy and unsuitable for a small patio pot.
Use a sunny, warm position and a container or bed that drains freely. Allow the growing medium to guide watering rather than keeping it constantly saturated. Young plants are particularly sensitive to unsuitable conditions. Confirm that you have annual flowering vinca, since the same common name is also used for different perennial groundcovers.
Use the cultivar's mature habit and packet spacing, since compact types and large branching plants need different amounts of room. Leave enough space for air to move through the foliage. Planting every variety at the tightest spacing can create crowding as they grow. Choose a sunny site and water at the soil when practical.
Remove spent blooms and harvest flowers regularly instead of allowing all the heads to develop seed. Pinching young plants can encourage branching where appropriate for the variety. Keep them in sun with suitable spacing and moisture. Do not crowd the plants to make the bed look full immediately; they need room as they expand.
