Generally September is regarded as a month in which quite a lot of clearing up can be done. Certain plants have finished blooming and if they are annual varieties can now be disposed of on theheap. Vegetable remains can also be cleared away and the ground forked over. This is a good time of the year to begin building another compost heap. Plenty of lawn and other garden refuse is available and can be used for this purpose. The new heap should however be carefully built according to the instructions which can be found in an earlier **chapter**. When left to completely rot this new compost heap will provide valuable compost for when the is being prepared for next season’s planting.
During very dry periods however, water should be introduced into the heap from time to time as this will help rotting to take place successfully.
Do not add to the existing rotted heap but build the new one completely separately as any compost already decayed can be used whilst decomposition takes place in the new heap.
As the weather begins to get more windy the taller herbaceous border plants must be checked for efficient staking, and plants tied up where necessary.
Keep hoeing over the borders to keep thedown before they can reproduce themselves.
Look over the rockery and tidy up any uneven growth on the plants. This is a good time of the year toof alpines, and existing rock plants may now be lifted, divided and re-planted.
Cut backafter flowering has finished and re-tie them to their supports if these are in good condition. Any repairs necessary to the wall trellis or wire supports can be undertaken while the are detached for pruning.
Cuttings may be rooted this month of geraniums,and many bedding plants.
Irises and hardymay also be planted along with anemones.
Spring flowering bulbs will become established early if planted this month, and with the exception ofmost bulbs can now be set. These include crocuses, , narcissi, scillas and snowdrops.
The rooted cuttings of carnations taken earlier by themethod can be planted out now together with of polyantha.
There are many types of dwarf bulbs to be grown on the rockery and September is an ideal month to get them planted. Bulb catalogues frequently list and illustrate these and they really are worth the trouble planting as they remain in position each year without having to be disturbed, and the blooms are most attractive.
Earlynow in flower must be given sufficient water during dry periods.
September is the best time to sow the seeds for a new lawn but the ground must have been well prepared before actual planting takes place.
On establishedsome extra care should be given to get the grass in good condition before winter arrives. A thorough raking and spiking can be made over the entire surface and a good dressing of lawn fertilizer given. Do not run away with the idea that this will only encourage the grass to grow quicker and so give the gardener more hard work to do to keep it mown. Feeding the grass at this time of the year keeps it healthy and strongly rooted. A good closely knitted lawn will not suffer from nearly as many as a poor undernourished one will.
Continue to mow regularly this month and gradually begin to raise the cutters a little at a time to leave the grass slightly longer during autumn. Water during dry spells.
Trees and Shrubs
This month is the most suitable for transplanting evergreen shrubs. The preparations can be made to the new site before the shrub is actually dug up so that when it is actually transferred with plenty of soil around the roots, very little set back will occur.
When the shrub has been moved and re-planted it should be watered in well and sprayed overhead with water for a few days until sufficient moisture is being taken up naturally by the tree. This will save the foliage from any unnecessary drying out.
hedges which have become too large and thin at the bottom can be thoroughly pruned now. Cut the hedge down drastically to about 2-½ feet from the ground to encourage new shoots lower down. Dig in a quantity of compost or peat which will help to act as a moisture retainer and feed the complete hedge with a good balanced fertilizer.
Rambler roses can now be pruned. Cut away the oldest branches down to ground level as new growth to flower next season will be growing up and can be tied to the supports as replacements.
Prepare any new rose beds this month in time for the arrival of new roses ordered for delivery in November. Generally weed and hoe around existing beds and continually remove flower heads as the blooms fade.
Geraniums which are intended for winter flowering should now be placed in the sunniest position in the house.which have been flowering in the borders may now be lifted and potted up. These should be kept quite dry during the winter in readiness for the following February when they must be cut back and growth re-started by application of water.
Now that the hottest part of the year is over, all of the remaining shading on the greenhouse glass can be washed away and a check made over any heating appliances which will soon be needed as the colder weather approaches.from the flower border will have nearly died back and these can be lifted and stored in a dry part of the house or shed for the winter.
Prepare containers of soil or bulb fibre for planting with spring flowering bulbs for the house and keep them in the dark for a few weeks following planting.
Grease band all fruit trees during this month and give the soft fruit garden a good hoeing over.
Remove any remaining strawberry runners which are not required for planting as new stock.
Prepare storage boxes ready for harvesting the apples etc. Stored fruit should wherever possible be kept in even temperatures, wrapped separately and placed in single layers in open topped trays.
Get the ground ready for new fruit trees and make sure that the varieties chosen for purchase will suit local conditions as far as possible.
Harvesting vegetables begins in a big way this month and rewards received for the hard work put into the plot during the planting and growing season.
Onions may have their tops bent over and any that are already ripe may be lifted. Leave them spread out for a day or two to dry before storing.
Cauliflowers andcan all be planted during this month and transplant any available or savoy plants into vacant ground in the plot.
Celery andshould continue to be earthed up as this becomes necessary.
