Here Is Your August Garden To Do List
Stake tall or top heavy perennials such as Dahlias, Peonies, Delphiniums and Lilies to prevent wind and rain damage.
Divide peonies now. Replant in a sunny site and avoid planting deeply.
Dead-head bedding plants and perennial plants to stop them self-seeding and to encourage further flowering into the autumn.
Clip ripening seedheads from plants that tend to self-sow aggressively, like Joe-Pye weed, comfrey, lemon balm, cleome and money plant.
Pot up and bring some of your favorite herbs indoors. parsley, rosemary, chives, thyme and marjoram do well like this.
Cut back faded perennials to keep borders tidy.
Keep your Camellias and Rhododendrons well watered at this time of year to ensure that next year’s buds develop well.
Keep patio container plants well watered and fertilize them with liquid fertilizer every two week.
Prune summer flowering shrubs once they have finished blooming.
Trim your Lavender plants after they’ve finished flowering to keep them compact.
Prune climbing roses and rambling roses once they’ve finished flowering (unless they are repeat-flowerers in which case leave them).
Water your vegetable plants and fruit plants daily in warm weather.
Pinch the top of tomato plants to concentrate the growth into the fruit that has already formed. Aim to leave 5 or 6 trusses of fruit per plant.
Plant seeds for fall leafy greens such as kale, spinach, chard and lettuces.
Protect ripening fall pumpkins and winter squash. Slip a piece of terra-cotta beneath them to prevent rot on the bottom.
Cut back herbs now to encourage a new flush of tasty leaves you can harvest before the frost.
Pinch the tips of your runner bean plants once they reach the top of their support. This encourages side-shooting and more beans at a manageable height for picking.
Start harvesting potatoes as the leaves yellow and die back.
Don’t worry if your lawn is looking brown. It is going into summer dormancy. The fall rains will soon make it green again.
Turn the compost in your compost bins every month to keep it well aerated and to speed up decomposition.
Keep bird baths topped up in hot weather.
As you work in the garden this month, remember to keep yourself well hydrated too!
