Harvesting what crops you have left

Harvest crops you have left in September

September is the time to harvest anything you have yet to harvest with the exception of things like leeks and parsnips which can be done later. Some crops like onions tell you when they are ready by flopping their leaves over and starting to turn yellow. Check them first to ensure they have not been damaged and that no insects have penetrated the onion below the soil and then enjoy.

Store extra crops and lift punkins and quash off the ground

All the extra crops can be stored in plant trays or old net bags, some nurseries even sell old net bags for a few pounds for a bundle or give them away free. Things like pumpkins and squash need to be lifted off the ground so that they can ripen in the sun before you harvest them.

If you are weather has already brought with it a great deal of rain, you can cut things like pumpkins and squash prematurely and leave them in your home inside of a sunny windowsill or in a greenhouse to ripen.

Remove tomato fruit in September and store them to ripen in the sun

Remove fruit from tomatoes and let them ripen

If you are removing your tomato plants and you still have some late bloomers that are green, bring them inside as well and allow them exposure to sunlight, eventually, they will turn red and be ready to eat.

 

Prepare fruit for storage

If you have fruit you want to prepare for storage, Harvest it and leave it in a warm room for at least two weeks. After that place them in a cool, dry area. There are certain fruit varieties, specifically apples, that are best eaten as soon as they are picked like Malus Discovery. So be cognizant of what varieties you have and whether they should be consumed immediately, converted into jams, or saved.

Preparing for Spring

Start planting winter and autumn bedding in September

It might seem like it’s a long way off, but September is the time to start preparing for spring. If you want a beautiful floral display at the beginning of Spring, you have to start planting your spring plants now including things like pansies, violas, primulas and Wallflowers which you can get bare root. If you go to your local garden centre, you should find a great selection of things you can plant immediately in trays. Pansies and violas are particularly good as they will flower through winter and well into spring.

Once you plant them, of course, water them well and deadhead regularly to promote more flowers.

Plant spring-flowering bulbs

You can also purchase your spring-flowering bulbs while buying your spring bedding. When picking your bulbs always choose firm, plump bulbs that have no mold. It is recommended that you plant bulbs as soon as possible, and if you see that they have started putting down roots, head out into the garden. Bulbs worth planting include daffodils, snowdrops and tulips

The cooler temperatures of autumn are good for tulips so if it’s still quite warm in your area you might want to hold off for another month.

Patio maintenance

September is when you should focus on the plants you have in containers on your patio. Continue deadheading if they are still producing blooms. If the weather is dry and you should give your plants some extra water. 

 

Feed summer containers to give them one last boost

If you are able, add some weekly liquid fertilizer to give them a boost. At this point the controlled-release fertilizer as you may have been using throughout the spring and summer will likely have run out which is why is well worth adding some liquid feed to keep them going that little bit longer, most will continue until the first frost arrives.

Tackling perennials – start dividing perennials

If you have perennials, now is the time to divide them. In order to divide clumps of perennials, you need to remove them from the ground, cut them into pieces by pulling them apart with garden tools like forks or shovels, or simply cutting them with a knife or even a spade.

Ideally, each piece you cut should have some leaves and roots. Then replant these new clumps wherever you want your perennials to thrive. 

Certain perennials do best if you divide them every few years such as agapanthus. This helps to prevent clumps from growing too vigorously, and is particularly important if your perennials are outgrowing their allocated space.

Plant those last few vegatables

If you are planning to grow more vegetables, now is the time to plant kale, chard, spinach, coriander, Dill, lambs lettuce, pak Choi, spring onions, and Rocket lettuce.
