High populations of thrips are promoted by a mild winter and a sunny spring.
Symptoms:
- Thrips are tiny brown or black insects (approximately 1 mm in length) and are most often found between the petals of the flowers.
- Their mouthparts pierce plant surfaces causing browning of petals and distortion of flowers.
- Leaves are distorted and generally curl upward. The leaves become crinkled and the laminae may be greatly reduced by high populations causing new leaves to be narrow.
The discolouring on the edges of the petals in the picture is caused by thrips.

This picture shows distorted leaves caused by thrip damage.
Pest development:
Survival of hibernating thrips is promoted by a mild winter, a sunny spring and abundant weeds. Female thrips lay colourless eggs in floral tissues. Adults feed on flower parts, later entering the soil to pupate. Thrip life cycles can range from 10 days to a month depending on temperature.
Control:
Spray with a registered chemical and remove weeds.

Botaniese naam
Veltheimia bracteata.
Gewone naam
Boslelie (Die gewone naam mag verwarrend wees omrede daar ook na die Clivia as ‘n boslelie verwys word).
Groeibeskrywing
Bolplante met blink breë blare, lang blomstele en trosse buisvormige blomme. Blare word in die middel van die somer met nuwe blare vervang.

Blomme
Blom in die lente. Blomme is stofpienk met groen punte. Blomme lyk baie soos aalwynblomme en hou ongeveer 30 dae.
Tuinplasing
Plant die bosboslelie in groepe onder bome of as potplante in die skadu op patios. Plant in goed gedreineerde grond wat met kompos verryk is.
Hoogte en wydte:
45cm x 30cm
Land van oorsprong
Gehardheid
Slegs gedeeltelik kouebestand en moet daarom op beskutte plekke onder bome geplant word.
Voortplanting
Plant voort deur middel van saad of sylote.
Botaniese naam
Impatiens
Gewone naam
Impatiens, Busy Lizzie.
Groeibeskrywing

Klein een of meerjarige struikies wat om hul helderkleurige blomme geplant word.
Blomme
Verskillende hibriede, gekenmerk deur ‘n verskeidenheid kleure, is by kwekerye beskikbaar.

Die plantnaam hou verband met die skielike “ongeduldige” manier waarop die ryp vruggies oopskiet wanneer dit aangeraak word.
Tuinplasing
Plant in volle skadu. Hierdie is die ideale plantjies om kaal skadukolle te versier. Impatiens is gevoelig vir koue en moet daarom eers aangeplant word wanneer die ergste gevaar vir ryp verby is. Impatiens vertoon ook mooi in houers op patios en binneshuis.
Besproeiing
Impatiens verlep maklik en moet daarom feitlik daagliks benat word.
Hoogte en wydte
30cm x 20cm
Gehardheid
Rypgevoelig.
Voortplanting
Plant maklik voort deur middel van stiggies.
Land van oorsprong
Tropiese Asië en Afrika.
