This week, I've some tips on plant care if you're lucky enough to be away, some propagation ideas and some planning ahead for winter planting, including priority planting of some great bulbs. But make sure whatever you get up to in the garden, enjoy it!

Watering and holidays
- Indoor plants will survive your absence if they have enough water. Putting them in the bath on top of an old wetted towel may also be enough. Placing them on a draining board covered by capillary matting -with the ends in a partially filled sink- works well too.
- It may seem obvious, but this is the time of the year that saucers under pots help to stop plants drying out by increasing the water holding capacity.
- Ask a neighbour, friend or relative to water your plants for you while you're away. Encourage them to take vegetables and fruits that otherwise would go to waste.
- Moving plants to the shady side of your home will help reduce water demand.
- Sow seeds of autumn onion (sometimes called Japanese onion) this month to give you the earliest crop of next year. You’ll be able to buy onion sets of these next month, but seeds are cheaper!
- Harvest all marrows and cucumbers regularly. If you don’t, they will also stop producing. Give excess away or conserve them. It's even better to throw excess on the compost heap rather than leave them on the plants!
- Remove lower leaves if they show signs of powdery mildew. Try spraying with a mix of 50:50 milk and water. Let me know if it works for you too!
- Remove lower leaves from tomato plants when they start to show signs of going yellow. Removing them too soon can lead to uneven fruit ripening.
- Keep watering tomatoes evenly. If it varies too much, your fruits may get dead black tissue at the bottom end called ‘blossom end rot’.
Flowers and ornamental plants
- Trim lavender as the colour fades from the flowers. Remove just a little bit of the shoot too, as this will encourage branching out. If plants have become straggly, delay harder pruning until late spring.
- If you want to dry lavender, then you need to harvest the flowers before the colour fades. Hang them upside down in a cool, dry and airy place.
- You can take semi-ripe cuttings of many plants now. These are cuttings that have a slightly hardened and woody lower end and will root best on a mist bench. It's surprising what will root in a pot of compost covered with a thin polythene bag.
- Get catalogues as they become available and order ornamental trees for winter planting. These will normally be delivered in mid-winter.
- Autumn flowering crocus should be planted as soon as possible as they will flower this October. They bloom before the leaves appear and this has earned them the common name ‘naked ladies’.
- Hyacinths prepared for forced flowering around Christmas will be coming out of temperature treatment now. Get potting them up for some inexpensive scented decorations for Christmas!
- Plant Nerine bulbs in a position where they get plenty of sun and where the soil dries quickly. By a wall or hedge works well.
