Garden Calendar – September
September is generally a cooler, gustier month than August and the days are noticeably shorter. In nursery, it’s time to get out and start planting spring-flowering bulbs for next year.
i.Strong growing tall annuals may be planted in newly planted shrubberies to fill up spaces caused by slow growth of permanent shrubs.
ii.Climbers should be finally overhauled, unwanted growth trimmed out and the plants tied in position. Water copiously and if the plants seem exhausted apply manure.
iii.Foliage plants in pots may be moved into position for decorative use protecting them from the hot mid day and afternoon sun.
iv.Chrysanthemum should be taken care of as the treatment they receive now will determine the quality of bloom two months hence.
v.Carnation in pots carried forward from the previous years may be pruned and transplanted into new soil.
vi.Final sowing in the seed beds of acclimatized seeds of winter flowering annuals required for beds and borders should be made.
vii.Monsoon and summer flowering annuals may be removed as soon as they cease to flower in order to allow time to prepare the beds and borders for winter use.
viii.Beds and borders required for winter flowering annuals should be finally prepared.
ix.Application of ammonia sulphate or nitrate of soda at the close of the monsoon.
x.Cutting of Geraniums are planted for flowering in January- March.
xi.Good time to redevelop lawn and also to establish new lawns. Mowing of lawns is necessary. Topdressing can be done and if required fertilizer application can also be done followed by watering.
xii.Suckers and bulbils of Cycas should be planted.
xiii.Seeds of Cycas can be sown.
September Pest and problems:
•Monitor and treat for grubs in lawns if required. Treating is only necessary if 10 or more grubs are found in a one square foot area when grass is actively growing. Apply Monocrotophos as per the instruction provided.
• Scorch is a common problem in hot, dry weather. The plants should be well watered during periods of drought. Stressed plants are more susceptible to attack by insects and disease. Many plants may also exhibit wilting leaves or yellowing foliage due to lack of adequate water. Water during dry spells.
• Galls are common on many plants throughout the season. Generally galls on leaves are just cosmetic and do little damage. Horned and gouty oak gall affects twigs and, although usually not a serious threat to the health of the tree, can be unsightly. Unfortunately, little can be done to control them. The galls can be removed, but there is no guarantee that they will not recur.
• Good time for planting of winter flowering plants both in beds and pots.
• Finishing of planting and transplanting activities during this month.
• All nursery activities continue.
