Conservatory Plants

Conservatory plants thrive in the higher light levels of conservatories and glasshouse. They tend to be subtropical plants, accustomed to the high levels usually found in hot countries but not minding cool winter temperatures and often appreciate a cool winter resting period.

WATERING:  As a general rule, when the compost begins to dry out, give enough water to reach the bottom of the pot, preferably washing a little out through the bottom each time.

FEEDING:  Feed plants each week in Spring and Summer when they are growing strongly, reducing down to perhaps every 4 weeks, in Winter if plants are kept cool enough to be dormant. Use a fertiliser high in potash for flowering plants, a high nitrogen fertiliser for green plants and a seaweed or special Citrus fertiliser, high in trace elements for Citrus trees to keep them green and fruiting. Wash pots through with clean water twice a year to avoid a build up of unused fertiliser salts. Slow release granules can also be used to good effect on house and conservatory plants.

VENTILATION: Before putting plants into a conservatory, ensure there is enough ventilation to keep the room cool in hot weather and to allow ventilation when out. In Winter, plants appreciate fresh air to help prevent fungal diseases building up. Citrus trees benefit from adequate ventilation or they tend to drop leaves and fruit.

TEMPERATURE: Excessive heat can put stress on plants and create excessive watering. Subtropical plants are happy at 4-8oC, and many thrive in unheated glass. Keeping plants above 6oC will allow a large range of varieties to be grown.

REPOTTING: When plants become too big for their pots, they dry out too quickly and become stressed. To check the roots, remove pot with a sharp tap and see if rootball is too full and tight. Re-pot in Spring or Summer, when growth is strong, and plant in pot about 2-3cm (1”) bigger. Use a compost matching the previously one used checking if ericaceous compost is required. Water well after potting.

PRUNING: Generally prune after flowering to give a full year for glowering growth to develop, or in late Winter/early Spring just as growth is starting. Pinching out tips of bushy plants regularly can reduce the need for drastic pruning, and produces a nice well-shaped plant with lots of flowering shoots. (Be careful with poisonous plants like Datura and Oleander, using gloves where possible).

PESTS: Watch for sticky deposits or black sooty mould. At the first sign of pests, spray with an insecticidal soap or a chemical spray or biological pest controls used in accordance with instructions.
