The most suitable size is the right one, neither more nor less. It is not very convenient for the pot to be too large, however, terrace plants need somewhat larger containers while indoor plants should be kept in smaller pots.
A plant that has been over-watered shows fairly easy to identify symptoms. The leaves turn yellow, curl and take on a brown hue at the edges. In addition, continued excess water leads to root rot, the flowers become moldy and a whitish fluff appears on the ground, others need to be watered only and exclusively when necessary, this is appreciated by testing hydration even manually of the substrate to water just when it is necessary and depending on the time of year
Any type of seed needs a pleasant temperature to germinate, that is, a temperature that is neither too cold nor too warm. For this reason, without having a suitable and protected place such as a greenhouse, where the seeds can be provided with the appropriate temperature, the best time for sowing is spring.
Except for annuals and biennials, which die after flowering, all others are pruned. It is convenient to prune the plants that bloom in spring just at the end of this and not leaving much more time because if it is not likely that it will not bloom next season. Perennials and hedges should be pruned in early spring and late summer. Summer roses and shrubs should be pruned in the period between late winter and early spring.
Basically almost all plants support potting, what must be taken into account is that depending on the species / variety to be grown is the growth rate it has, it is easier for plants with minimal root development to adapt better to smaller spaces.
