• I’ve been using Growpots to grow tomatoes for several years now and am convinced that they improve the performance of growbags. I needed to go online to remind myself about the watering routine and I thought it might be useful to show the planting up process.
• Before you start, give your growbags a good shake to make sure the soil is evenly distributed and not lumpy. I use New Horizon Organic & Peat Free Growbags.
• Pierce several holes in the bottom of each growbag and put them in position. Each growbag will support 3 Growpots.
• Use the serrated teeth on the bottom of the Growpot to cut a hole in the growbag – you will need to twist firmly.
• Once the Growpots are in position push a cane into each one – I tie the canes to wires stretched across the greenhouse to keep them firmly in place.
• Half fill the Growpots with compost and plant your tomatoes.
• Add half a liter of water to the inner pot and fill the outer trough to the rim and leave to seep into the growbag. For the first 2 weeks don’t add any further water to the outer ring.
• For the next month pour a liter of water into the outer trough every second on third day, preferably in the morning.
• Water and liquid feed the inner pot at least once a week – it mustn’t dry out, but do not use tomato feed until the first fruit has set – before that use a week solution of general purpose plant food
• After that fill the outer trough with water every day on hot sunny days
• Once the fruit starts to ripen gradually reduce the amount of water.
