We leave the vents and doors of our Pelargonium house open all summer, from the end of May to the end of September. We open the vent on our greenhouse for a few hours each day, whatever the temperature outside. Fail to ventilate each day, and botrytis will become a major problem. Botrytis spores are always present in the atmosphere, but in a well-ventilated dry greenhouse, they will remain at modest levels. Pelargoniums hate poor ventilation as much as they do frost. No more waking in the morning to find your plants all frozen through, their foliage limp and black, the air already fetid with putrefaction! Thus speaks the voice of experience. On most models if the temperature falls below a programmed level an alarm is triggered, giving you the chance to jump from your bed and clad only in night shirt and wellies…. These require no wires and the monitors keep in touch with the sensor by radio signals. A new technological development is the availability of remote sensors, which can be placed in the greenhouse and be monitored in the house. Perhaps the best solution for the small greenhouse is to line it in winter with bubble wrap this cuts down hugely on heat loss and makes an electric fan heater much more economical. While paraffin and gas burners are cheaper to run than an electric fan heater, they emit a large amount of moisture, which will increase problems with botrytis. The Pelargonium greenhouse should be equipped with a heater and kept frost-free at all times. In a mild winter a cold frame may be adequate if the temperature is monitored. In the winter it is advisable to house them in the greenhouse, conservatory or in the house. You can increase the air in a compost using additives such as pearlite or diatomaceous earth.įrom the last frosts in May to the first frosts of October most Pelargoniums can live outside, in fact they benefit hugely from being in the garden during the summer months. For cuttings and seeds make sure you use a fine compost. We recommend using good quality composts from well-known suppliers, Sinclair’s or Levington’s. This is usually given as a percentage, the higher the percentage the more air in a mix. (AFP) is an indication of how open in structure a compost is. This is known as AFP – or ‘Air Filled Porosity’. Soil or loam based composts like John Innes are too heavy, Pelargoniums prefer compost with an open structure that does not compact over time. Multipurpose composts are not really suitable, as they lack structure and quickly collapse and become stagnant. Pelargoniums, although not difficult plants, are fussy about potting compost. However this can increase during busy periods Orders placed from early April onwards will be dispatched within our normal mail order time frame which is usually 5-7 working days. Orders placed from January to late March we aim to dispatch in the first two weeks of April. Please note you can only combine orders going to the same address. We will then send the orders all together and refund you back any additional postage paid for. If you wish to combine orders simply add to the ‘order notes’ box at the checkout – ‘please combine my orders’. You can add to your order anytime before dispatch in April. The best time to order is between January-March, as early as possible. We stop adding new stocks to the website in late autumn when we begin propagation for the following year. We continue to propagate throughout the spring and we add subsequent stocks to the website as they become available. In January we release our first availability of the season, this is done around 20th January and offers eager customers the opportunity to order plants for dispatch in early April.
