They lay eggs at the base of onion plants, and the larvae tunnel into onion roots. Damage: When young onion plants wilt for no apparent reason, pull up a sample plant to check for legless worms (maggots) feeding on it roots.

Crop Rotation Group Miscellaneous ● Soil Any average, well drained soil. After two years, valerian will grow into a 18" (45 cm) wide clump. Feeding Not generally needed. Dried valerian roots are used to make a bedtime tea that promotes sleep.

Frost tolerant A cold-hardy perennial, lemon balm can survive temperatures to -20F (-30C). Feeding Not generally required. Harvesting Gather sprigs as needed in the kitchen. Lemon balm can be transplanted from early spring to early summer.

Feeding Topdress with rich compost in spring, when new growth appears. Perennial candytuft makes an ideal companion plant. Harvesting Cut tulips to use as cut flowers just as the buds open.

Crop Rotation Group Miscellaneous ● Soil Fertile, well-drained soil. Spacing Single Plants: 7" (20cm) each way (minimum) Rows: 7" (20cm) with 11" (30cm) row gap (minimum) Sow and Plant Sow tiny ageratum seeds atop moist seed starting mix and gently...

A wide hole is better than a very deep one. Begins to bear after five years. Notes Self-fertile but pollination is improved by growing in groups with two or more cultivars present.

When bulbs form and the tops of the plants fall over, pull them and cure in a warm place for about 10 days before storing. Seedlings are less likely to bolt (produce flowers) compared to bulb onions grown from sets.

Crop Rotation Group Cucurbits (Squash family) ● Soil Rich soil with plenty of compost added. Notes Fruit size, flesh color and texture varies with variety and type of melon. Companions Tansy, Nasturtium and Catnip.

Damage: Meandering tunnels in apples, just beneath the skin and extending to the core, are usually the work of apple maggots. The larvae move from fallen fruit to the soil to pupate.

Spacing Single Plants: 11" (30cm) each way (minimum) Rows: 9" (25cm) with 1' 1" (35cm) row gap (minimum) Sow and Plant Only a few lantana varieties are available as seed, but it is better to start with vegetatively propagated plants because they are seed...

Frost tolerant Young seedlings easily tolerate spring frosts, and may survive winters in mild climates. The easiest chamomile to grow is a cool-season annual. Chamomile tea is made from the blossoms only.

Good drainage is essential. Frost tolerant No. Grow at temperatures above 7°C (45°F). Grow in containers of rich compost to keep plants compact and to make it easy to bring plants indoors for the winter.

Mature white currants bear best on two-year-old branches. White currants freeze very well. Notes Powdery mildew can be a serious problem for white currants, so consider planting resistant varieties such as ‘Blanka' or ‘Pink Champagne'.

Preventing Problems: Use row covers to protect plants during the 6 to 8-week period while Japanese beetles are feeding. Damage: Japanese beetles chew holes in leaves, often devouring much of the foliage from roses and other favored plants.

Frost tolerant A hardy perennial from the Mediterranean, lavender will survive winter temperatures to 0F/-17C. Feeding Not generally needed beyond annual topdressing with rich compost in spring.

Notes Peaches may need to be hand-pollinated when grown in sheltered spots. Young peach trees are at high risk for damage from insects that bore into the main trunk. Crop Rotation Group Miscellaneous ● Soil Moisture-retentive but well-drained.

If there are holes in the trunk which leak a gummy substance or sawdust-like frass, the culprit is probably a borer or beetle – to kill this pest, poke a needle into the hole. However, because cherries ripen early, they have fewer disease problems compared...

Frost tolerant Yes, but flowers can be damaged by late frosts. Feeding Mulch with well-rotted organic matter in spring. Harvesting Knock down nuts when ripe, remove the peel and dry.

Managing Outbreaks: Diamondback moths have become resistant to most pesticides, including Bt. Hand picking is a better option, and can make a big impact when you check your plants every day.

Follow up with two applications of insecticidal soap, one week apart. Managing Outbreaks: In small outbreaks, a high pressure spray from the garden hose can help remove aphids from plants.
