It seems like only yesterday you were brushing up leaves and tidying the garden ready for spring. Now spring is almost over and summer is just a couple of weeks away. The weather is much warmer and the threat of frost is no longer an issue. There’s lots of preparation work you can be doing. You can also thin out those plants that are already sown. Protecting the plants inside your greenhouse is also worth considering. June is also a busy time for planting and sowing seeds.
Flowers You Can Plant in June
Flowers for planting in the Autumn, such as primrose, polyanthus and pansy can be sown in the greenhouse. Plant the seedlings out in a few month’s time, and you’ll have a riot of colour next spring. Flowers you want to enjoy this year can now be sown outdoors. These include canterbury bells, sweet williams and achillea.
Any hardy annuals you’ve already sown will appreciate being thinned out now. Bedding plants that are already growing can be potted up and will provide a glorious display on a balcony, patio or windowsill.
Planting Young Plants in June
The bedding plants that you’ve been protecting can now be planted outdoors in their rightful places. It could be in hanging baskets, containers or a garden border. To help any potted plants grow when taken outside you should apply a weekly liquid feed. This will ensure you can enjoy them all summer long. When planting out young plants pinch out any shoot tips to encourage new growth and branching. Remove dead flowers or buds so the plants energy isn’t wasted.
Roses and Bulbs
Sprinkling rose fertiliser will encourage strong growth. You can also gently hoe around the base and gently water in. Spring bulbs will have finished flowering so you can remove any dead foliage and seed heads. Daffodils and tulips should be left to die back naturally.
Beetroot, carrot and lettuce should already be planted and growing well. June is the time to thin them out and make further sowings. Carrots should be protected from carrot fly. A good way to do this is to use raised beds. Vegetables such as cabbage, brussel sprouts, marrows, cucumbers and courgettes can be brought out of the greenhouse and planted outside.
If you’ve been growing strawberries under glass or cloches you need to uncover them so that the insects can do their job of pollinating. To prevent birds from eating your growing fruit, cover them with a fruit cage or netting. Raspberries and blackberries will soon need support.
