Start to feed citrus plants – oranges and lemons. I have them in pots which I protect during the winter.
Increase the water given to houseplants – tidy them up, check if they could do with a compost freshen up and take cuttings.
Feed hungry shrubs and roses. Chicken manure pellets are a great slow release general fertiliser.
Sow new lawns or repair bare patches. Only time to water grass is when it has been seeded.
Plant summer bulbs, corms and tubers – Dahlias, Begonias, Gladioli, Calla Lilies (Zantedeschia) ,Lilies to name a few.
Vegetable seeds – here are a few – corn,broccoli ,beetroot, kale, peppers (Capsicums), Perpetual spinach, tomatoes again wonderful opportunity to sow perennial seeds to flower in your garden for many years.
