Problems

Bolting

Premature flowering, often triggered by heat stress, water shortage, or long days. Reduces leaf quality and yield. Premature flowering due to stress (heat, drought, long days).

Problems

Waterlogging

Excessive soil moisture leading to oxygen deprivation at the roots and promoting root rot. Leads to root rot, wilting, and plant death. Leaves may turn yellow.

Problems

Frost damage

Damage to blossoms or young fruit caused by late frosts. Leaves and shoots turn brown and wilt due to frost. Young plants are particularly vulnerable.

Problems

Premature bolting

Plant goes to seed too quickly, usually due to heat or drought stress. Plant flowers too early due to drought stress or heat.

Problems

Poor fruit set

Insufficient pollination (lack of wind, absence of pollinators) Flowers are not pollinated or do not develop into fruits.

Physalis pruinosaPhysalis peruvianaEggplantChayoteRaspberryJostaberry

Problems

Poor fruit set

Insufficient fruit development despite the presence of flowers. Can be caused by unfavorable weather during flowering (rain, cold, wind), insufficient pollination, or nutrient deficiency.

Problems

Late frost damage

Early-blooming apricots are susceptible to late frosts, which can destroy blossoms and young shoots. Crop loss due to frozen blossoms in May.

Problems

Bolting

Cold stimulus in seedling stage or drought stress. Choose varieties appropriate for the growing season

Problems

Fruit cracking

Splitting of the fruit skin shortly before ripening following heavy rain on dry soils.

Asian pearEuropean PlumQuinceDamson plum

Problems

Bolting

The plant prematurely forms a flower stalk, which inhibits root development and reduces root quality. Premature flowering due to heat or lack of water.

HorseradishBok choyRomaine lettuceRomanesco broccoli

Problems

Fruit splitting

Heavy rain after dry spells during ripening. Sudden water uptake after drought causes skin to burst.

Common FigPepinoGreengage

Problems

Bitter leaves

Natural bitter compounds in chicory, intensified by stress or bolting. Leaves develop an unpleasantly bitter taste.

Common chicoryArugulaSorrel

Problems

Bitter fruits

Stress reaction caused by cold irrigation water or drought. Fruits taste extremely bitter and are toxic.

Cucumberpattypan squashZucchini

Problems

Bitter taste

Some squashes can taste bitter, which is due to cucurbitacins. Can be caused by stress factors such as heat, drought, nutrient deficiency, or harvesting too late. Certain varieties can also be naturally more bitter.

Problems

Blossom drop

Often caused by extreme drought or heat. Night temperatures too low

Runner beanCommon beanPepper

Problems

Fruit drop

Unripe fruits fall prematurely from the plant. Premature dropping of fruits before they are ripe.

Physalis peruvianaRaspberryTomatillo

Problems

Poor Fruit Set

Poor fruit set can be caused by unfavorable weather conditions, nutrient deficiency, or pollination issues. Few or no fruits develop despite flowering.

Acorn SquashCherry plumWild Strawberry

Problems

Cold shock

Growth stops at temperatures below 10°C. Stalled growth, shedding of flowers and young fruit sets when temperatures drop below 12°C.

Common beanOkraMuskmelon

Problems

Sunburn

Damage to fruits and leaves caused by excessive sun exposure, especially on young plants. Direct midday sun on unprotected fruit

Problems

Woodiness

Plant sprouts sparsely if not pruned regularly. Older shoots become woody and unproductive

Problems

Bird damage

Birds love the ripe berries and can quickly destroy the harvest. Birds eat fruit before harvest.

Problems

Tip burn

Calcium deficiency due to irregular water supply. Brown, dry edges on inner leaves (calcium deficiency/stress).

Problems

Leaf discoloration

Unnatural discoloration of leaves indicating nutrient deficiency, diseases, or pests. Identify cause and treat accordingly (see diagnosis)

Tree spinachSpinach

Problems

Frost damage

Plant turns black and mushy Late frosts can damage young plants, while early frosts in autumn/winter can affect the harvest (often positively).

New Zealand spinachBrussels sprouts

Problems

Blossom end rot

A physiological disorder caused by calcium deficiency in the fruit, often exacerbated by inconsistent watering or rapid growth. Blossom end rot manifests as brown, sunken spots at the blossom end of fruits. It is caused by calcium deficiency or uneven water supply.

EggplantAcorn Squash

Problems

Fruit rot

Often caused by waterlogging, fungal infection (e.g., gray mold), or mechanical damage to the fruit.

red kuri squashwatermelon

Problems

Cracking of fruit

Sudden rapid growth of the fruit due to strong water uptake after drought can lead to cracks in the skin. Cracks in the fruit skin, usually caused by rapid water uptake after a dry spell.

ApricotEggplant

Problems

Yellowing Leaves

Leaves turn yellow. Can be caused by overwatering, waterlogging, nutrient deficiency, or the natural end of the life cycle.

Problems

Invasive Spreading

Horseradish can spread very vigorously and uncontrollably in the garden through its roots, outcompeting other crops. Mint grows uncontrollably beyond its designated bed

Problems

Poor Growth

Slow or insufficient plant development, often caused by nutrient deficiency, unfavorable soil conditions, or insufficient sunlight. small leaves

Problems

Cracked Bulbs

Bulbs crack when a sudden large amount of water is supplied after a prolonged dry period. The bulb rapidly absorbs water, and the outer layer cannot withstand the pressure. Inconsistent watering (sudden watering after drought)

Problems

Reduced yield

Lower fruit quantity than expected.

Problems

Slug damage

Holes in leaves Young leaves are occasionally eaten by slugs.

Problems

Sunburn on fruit

Damage to fruit from excessive sun exposure, especially on unshaded fruit. White or brown patches on fruits that become hard and dry.

AppleWild Strawberry

Problems

Late Frost Damage to Blossoms

Early blossoms freeze during late frosts, leading to low or no fruit set. Although honeyberries are very winter-hardy, late, severe frosts during flowering can damage blossoms and reduce fruit set.

Cherry plumHoneyberry

Problems

Uncontrolled spreading

The plant displaces other garden plants via its runners. As a perennial plant, sorrel can spread significantly through self-seeding or root runners.

Ground IvySorrel

Problems

Unripe fruits

Can be caused by too short a growing season, nutrient deficiency, or unfavorable weather.

red kuri squashwatermelon

Problems

Insufficient sunlight

Rosemary requires ample sunlight. Insufficient light leads to weak growth and reduced aroma. Although Tripmadam tolerates partial shade, too little light leads to sparse growth and loss of its typical compact form.
