Growing Guide – April


Jobs To Be Getting On With

Hopefully this month brings warmer weather with it, in which case you will need to keep your greenhouse ventilated. A good aim is to keep the temperature inside the greenhouse between 7 – 21°C (45 – 70°F). The roof vents should provide the majority of the ventilation, with the side vents only being used once the outside air is warmer.

As the temperature increases, your plants will become thirstier and you will need to check regularly to see if watering is needed. Plants that are actively growing may well need watering several times a week but remember over-watering can be as much of a hazard as under-watering!

Depending on the plants you are growing, the warmer temperatures may mean that the need to heat the greenhouse is reduced this month. Remember, however, that young plant growth is especially susceptible to low temperatures so check that heaters in the greenhouse are working whenever a frost is forecast.

Find out what to sow and grow this month in our April Growing Guide.

The seeds i sowed, For weeks unseen, Have pushed up pygmy, Shoots of green, So frail you’d think, The tiniest stone, Would never let, A glimpse be shown.
