August can be one if the first months of the harvest. Its been a bit wet so far but that could so easily change so keep the watering up during the drier days to make sure that your crops continue to swell nicely. If you are going away on holiday don't forget to ask a friend of neighbour to water regularly for you.
Continue to feed the bedding plants in your pots and hanging baskets to keep a good show all summer long. Feed at least every 2 weeks for the best results.
Also keep feeding your tomato and cucumber plants to keep them fruiting (as well as any other veg in pots). Ideally, feed each week.
Continue to deadhead flowers such as Roses, Penstemon, Dahlias and of course bedding to keep your plants flowering for longer.
It’s time to plant autumn flowering bulbs such as colchicums and start planning what spring flowering bulbs you want to plant.
It’s a great time for harvesting from your veg plot – keep picking veg such as runner beans, French beans, courgettes, mangetout & sugar-snaps to keep them cropping and prevent them from becoming tough.
Now is the time to give many of your herbs a trim. Whether you’ve been using them or not, it’s a good idea to give herbs such as thyme, rosemary, sage, winter savory and of course Lavender a good trim to keep them in a good shape for next year and harden them up for the winter. This is especially true for Lavenders, which is tricky as they are often still in flower but be brave and give them a good hair cut by the end of August.
Got space after lifting your spuds? There is still time to fill the gaps with plants such as perpetual spinach, rainbow chard, lettuce & salads, cabbage such as Wheelers Imperial, kales and purple sprouting.
If your garden is looking like it needs a colour boost in August then look out for stars of the month such as Hydrangeas, Perovskia, Rudbeckia, Echinacea, Verbena bonariensis, Helenium, Penstemon, Sedum, Japanese Anemone and Crocosmia. These look especially great when mixed with some ornamental grasses.
