A few pests and diseases rear their ugly heads at this time of the year so as well as my tips here, be sure to take a look at the resources in the 'Knowledge' section under 'Problems' for some more great tips.
For more gardening tips from me, go to my monthly tips for gardening in June.
Home grown food
- Harvest cucumber and courgette plants regularly, even if you can’t eat them! If you leave them on the plant, it will slow down the production of more. So if you have a surplus, perhaps share them with your neighbours or trade for something that they have grown!
- Autumn planted winter hardy onions and shallots may be ready to harvest now. You'll know if they are, as the tops fall over and then wither. Let the skins ripen thoroughly in the sun because they store better then.
- Stop harvesting asparagus so that it has a chance to build up strength for next spring.
- Sow more salad leaf mixtures in containers. These cut and come again salads are so much fresher and cheaper than shop-bought ones!
Trees, shrubs and roses
- Box trees in pots get hungry very quickly so I’d recommend sprinkling blood fish and bone on the compost surface as that has given the best results for me.
- If you are removing the dead flowers from Hybrid Tea and Cluster Flowered roses, you can cut these flowering shoots back hard and they will then throw up invigorated young shoots that will flower later this summer.
- Sow wallflower seed outside in seed drills. Soak the soil a day or two before sowing as this significantly improves germination. Sow thinly to develop bushy plants for transplanting into their flowering positions in autumn.
Weeding and watering
- Hoeing between plants regularly removes weed competition but also reduces water loss from the soil.
- If you have lots of planted pots and containers, invest in a drip irrigation system with a reliable time clock. This will help waste less water and can water automatically at night.
- When you are hose watering, soak the soil rather than wet the foliage. A good soak is better than a splash over every time you come home from work.
- Water early in the morning or late in the evening if you haven't got an automatic watering system. There will then be less water lost to evaporation.
- You can always link another water butt to your existing one. It's easily done if you add one that's a little shorter.
